  43. <content:encoded><![CDATA[
  44. <p>President Donald Trump has clipped the wings of Chinese aircraft company COMAC by halting the sale of critical engines, avionics and other necessities for its flagship C919 single-aisle airliner. After years of delay, the aircraft went into service in 2023 and has been ordered by most major Chinese airlines. COMAC also wants to certify the plane in the rest of the world and compete with Boeing and Airbus and the <em>New York Times</em> says Trump imposed the restrictions to protect Boeing. The restrictions also came shortly after China stopped exports of critical minerals to the U.S.</p>
  45.  
  46.  
  47.  
  48. <p>The C919 is now a relic of an earlier time when the U.S. and China were expanding trade opportunities. Aerospace companies, particularly engine makers, weren&#8217;t keen on sharing their tech with China, but they were willing to sell them finished products. The result was about 40% of the plane consists of parts and components made in the U.S. and other Western countries. Of those, the engines, made by LEAP International, a 50-50 partnership between GE and France&#8217;s Safran, are the most critical. China has not yet built a modern efficient airliner engine.</p>
  49.  
  50.  
  51.  
  52. <p>Some analysts claim the C919 owes a lot more than engines and panel to Western know-how. “Almost the entire makeup of the C919 is stolen technology from numerous aviation and technology industries from around the world,” said William R. Evanina, a former director of the United States National Counterintelligence and Security Center, said before Congress a few years ago. A Chinese official called the export restrictions &#8220;a malicious blockade and suppression of China&#8221; and said his country would fight them. </p>

  72. <content:encoded><![CDATA[
  73. <p>A mental health study of French airline pilots suggests a quarter of them grapple with serious mental health issues, including a few who had attempted suicide. It also found that more than 40% of the 1220 pilots who filled out the anonymous questionnaire had &#8220;misused&#8221; alcohol. About 3% had suicidal thoughts and three had tried to kill themselves. The survey interpretations were published in the journal <em>Frontiers in Public Health</em>.</p>
  74.  
  75.  
  76.  
  77. <p>&#8220;The results highlight that a significant proportion of French pilots suffer from psychological symptoms,&#8221; the study&#8217;s conclusions said. &#8220;A concerning finding was that more than a third of pilots exhibited alcohol misuse, which needs prevention efforts to reduce health risks.&#8221; About 28% of those surveyed said they would hide mental health issues from air medical examiners for fear of losing their licenses while 54% said they would talk about their problems if that fear was eliminated. About 15% said they&#8217;d sought help for psychological problems.</p>

  97. <description><![CDATA[Only 13 planes have been confirmed as destroyed.]]></description>
  98. <content:encoded><![CDATA[
  99. <p>Analysts are now poring over satellite images and military communications trying to determine the accurate toll on Russia&#8217;s strategic bomber force from Ukraine&#8217;s surprise drone attack on four air force bases Sunday. Ukraine at first said 41 long-range bombers, some of them supersonic, were destroyed, but that number might be generous. <a href="https://www.twz.com/air/what-ukraines-unprecedented-drone-attack-means-for-russian-bomber-force" target="_blank" rel="noreferrer noopener">According to the War Zone</a>, on Monday, senior Ukraine officials were only confirming that 13 bombers were destroyed, but that might be based on a conservative interpretation of the term. Satellite photos shot Monday over two bases appear to confirm the loss of at least nine bombers, most of them 1950s-vintage Tu-95 Bear turboprop bombers.</p>
  100.  
  101.  
  102.  
  103. <p>Regardless of the exact tally, the attack, which used 117 remotely piloted explosive drones hidden in the rafter spaces of cabins mounted on trailers, caused major damage to Russia&#8217;s closely protected and currently irreplaceable bomber fleet. The aircraft were being used as launch missile attacks on Ukrainian targets, many of them civilian areas, in recent weeks in an escalation that formed a backdrop for preliminary peace talks. The aircraft also form the backbone of Russia&#8217;s airborne nuclear weapons systems but it&#8217;s not clear any of the planes destroyed were engaged in that role.</p>
  104.  
  105.  
  106.  
  107. <p>Ukraine says that five different types of aircraft were destroyed, only one of which is currently in production, the Tu-160M2 long-range supersonic strategic bomber. Russia has fewer than 20 of them, and they take years to build at a cost of more than $500 million. Ukraine claims to have destroyed at least one of those in the attack. Ukraine also says Tu-22 Backfire bombers, an A-50 AWACS and an Antonov Cub transport were also wrecked.</p>
  108.  
  109.  
  110.  
  111. <p>The role of Ukraine&#8217;s allies in the attack was also being discussed, and Ukrainian officials claim the operation was conducted without any outside help. They also said they didn&#8217;t give any other countries, including the U.S., advance notice of the audacious raids. Russia&#8217;s response has been muted and on Sunday President Vladimir Putin called the raids a &#8220;terrorist attack.&#8221; The toll could have been higher. A fifth base was also targeted but one of the trailers full of drones was destroyed in a fire on its way to the target. The cause of the fire was not immediately known. The raids came on the day Russian and Ukrainian officials sat down for peace talks in Istanbul</p>

  129. <description><![CDATA[Aircraft development was pretty straightforward for the Wright Brothers.]]></description>
  130. <content:encoded><![CDATA[
  131. <p>A few weeks ago a rather desperate sounding plea landed in my inbox from someone who wanted to change the general aviation industry as we know it. He wanted instructions on how to go about doing so and the sooner the better. Some things just won&#8217;t wait, you know.</p>
  132.  
  133.  
  134.  
  135. <p>The temptation, of course, was to toss it into the virtual File 13 but I figured anyone who&#8217;s worked up the gumption to put this sort of thing to prose can take a few minutes from me so that I could at least politely tell him I couldn&#8217;t help him.</p>
  136.  
  137.  
  138.  
  139. <p>&#8220;Hi. I need guidance how i can get recommendation to join and connect with organization who believes diesel engine for general aviation. I am designer and engineer who make 2 stroke diesel engine for drone and urban air mobility. And I want move to America and make my engine cheap enough for less than 15000 USD for Certified and experimental plane . But I Don&#8217;t have any connection in USA. Please guide me how I can get in touch with organization or companies in USA. Thanks.&#8221;</p>
  140.  
  141.  
  142.  
  143. <p>There&#8217;s was something about the naked innocence of the request that intrigued me, so I responded. Turns out the fellow, who I&#8217;m not naming right now because I haven&#8217;t asked him if I can, has already built some engines, including one that powered an entry in the Dakar Truck Race and he said it went the distance and ran perfectly. He has a machine shop and what sounds like a track record and he&#8217;s pretty sure he can make a four-cylinder horizontally opposed diesel engine that makes 400 horsepower for a quarter of the price of anything comparable on the market today.</p>
  144.  
  145.  
  146.  
  147. <p>I&#8217;ve been in touch with him since and you may be hearing more about him. He seems aware of just how hard it will be to get anywhere with this idea but stranger things have happened. Actually, I&#8217;m not sure that&#8217;s really true because this is a pretty strange thing but I&#8217;ll keep you posted.</p>
  148.  
  149.  
  150.  
  151. <p>Just to make sure we both aren&#8217;t crazy, I checked with a couple of folks who should know better and they agreed that chances are this will go nowhere but stranger things have happened. &#8220;There’s always a small chance (when you dismiss guys like these) that you are telling the Wright Brothers they are idiots, and to go away,&#8221; was one of the opinions offered. Maybe I still have some innocence and naivety left in me but I&#8217;m going to see what I can do to at least get this fellow pointed in the right direction, assuming I can figure out what that is.</p>
  152.  
  153.  
  154.  
  155. <p>This inquiry came a few months after another Hail Mary call from an American who said he has literally run out of options to get the FAA to assess, and ultimately approve, an engine adaptation that he&#8217;s flown for thousands of hours and that has some staggeringly good numbers. There was a square peg somewhere in the process where only a round hole was available. Years of work and hundreds of thousands of dollars are at stake. He&#8217;s been dealing personally with the regulators but is no babe in the woods like the other fellow.  I suggested something he hadn&#8217;t thought of when dealing with stone-faced bureaucrats and it seems to be working the last I heard. I&#8217;m hoping to have an update on that one soon and maybe a pilot report on it.</p>
  156.  
  157.  
  158.  
  159. <p>Believe it or not this blog is about unleaded fuel and I cite these examples as a way to back into a treatise on just how hard it is to get anything done in this industry. The topic of new engines is relevant because either of these new designs would be capable of eliminating the need for high octane unleaded fuel if they work as the developers say they do. But mammoth obstacles in the way to develop and certify anything are so expensively huge that there&#8217;s little chance that will happen.</p>
  160.  
  161.  
  162.  
  163. <p>On the fuel front, as we&#8217;re reporting, a California judge has quashed an attempt by an environmental group to compel a couple of dozen FBOs and four fuel distributors to carry GAMI&#8217;s G100UL as part of a deal they signed to settle a lawsuit over the impacts of leaded avgas. I was impressed by the judge&#8217;s understanding of the issues but he seems to have a lot of faith in the FAA&#8217;s and industry&#8217;s ability to come up with a foolproof substitute for 100LL in the next five years. They&#8217;ve been at it for almost 40 years and nothing has worked well enough so far. </p>
  164.  
  165.  
  166.  
  167. <p>G100UL is being sold in California, Texas and Mississippi and by all accounts it works just fine in engines, including the high performance six-cylinder mills that use 70 percent of the avgas sold. There have been some complaints that it damages paints, fuel tank seals and rubber parts in fuel systems. The FAA is investigating those claims but, as far as I know, has not reached any conclusions on them. G100UL remains approved for use in about 98 percent of U.S. certified aircraft. That doesn&#8217;t mean the paint and seal issues don&#8217;t need attention but the FAA doesn&#8217;t seem that worried about them.</p>
  168.  
  169.  
  170.  
  171. <p>The other two candidate fuels are nowhere near as far along as G100UL. Swift Fuels 100R has been approved by STC for use in two models of Cessna 172, both of which are already approved to use 94 unleaded avgas. This year it will be tested on a Continental 550 that is also approved to use 94UL. Lyondell/Basell&#8217;s 100E is going through the FAA/PAFI process and after a year of testing is less than a third of the way through. So the judge&#8217;s confidence in the steady progression to a solution that everyone can agree on in the next five years seems a little optimistic.</p>
  172.  
  173.  
  174.  
  175. <p>Part of the process the judge seems keen on is obtaining an ASTM specification. As we all know, GAMI refuses to pursue that route because he doesn&#8217;t trust the integrity of the process. Both Swift and Lyondell/Basell say an ASTM spec is essential and they&#8217;re pursing it but as far as I know neither has attained it.</p>
  176.  
  177.  
  178.  
  179. <p>One of the reasons for my skepticism is the conduct of the court proceeding itself. The action was launched by the Center for Environmental Health, one of dozens of such organizations in the state that have been empowered by legislation to sleuth out and get legal visibility for threats to water, air and land. Leaded avgas is low hanging fruit in that context.</p>
  180.  
  181.  
  182.  
  183. <p>The CEH action was a continuation of a 10-year-old case they effectively won against a relatively small portion of the aviation fuel industry in the state. But the opposition to it was a massive onslaught of affidavits from a broad spectrum of OEMs, engine makers, several alphabet groups and the owners of planes who believed they were damaged by G100UL saying it was too risky to compel the sale of G100UL. The anti-G100UL side used one of the country&#8217;s most expensive law firms to make its case and it had to have cost millions. It worked. The judge agreed and implied he had faith the powers-that-be would sort it all out by 2030.</p>
  184.  
  185.  
  186.  
  187. <p>The only legal maker of tetraethyl lead, a British company called Innospec, is also banking on that. It wants desperately to get out of the lead additive business and since the FAA and EPA have both said 2030 will see the last of leaded gasoline, that&#8217;s become Innospec&#8217;s deadline, too. So it would appear that regardless of whether a substitute gets the consensus the judge seems confident will be achieved in four years and seven months, 100LL will go away.</p>
  188.  
  189.  
  190.  
  191. <p>That brings us back to our engine developers. One way to get rid of the myriad issues posed by the leaded gasoline debate is to build engines that don&#8217;t need leaded gasoline. Both of the folks I cited say they can do that. In fact, they both say they already have. They just need the paperwork to catch up. Simple, right?</p>
  192.  
  193.  
  194.  
  195. <p>By comparison, I think Orville and Wilbur had it relatively easy. They worked in obscurity, marking failure and success in inches and feet with no oversight and no legal challenges (those would come later). Their problems were purely physical and technological and as reasonable men they tackled them in a logical and practical way. They had many, many failures and more than a few crashes. It wasn&#8217;t until they had the solutions that they demonstrated their creation to the world. It was far from Utopian but it got done in a remarkably short time considering the lasting impact it had.</p>
  196.  
  197.  
  198.  
  199. <p>It was one of the stranger things that has happened to shape human destiny and it certainly wasn&#8217;t the last. Maybe we&#8217;re due.</p>

  306. <content:encoded><![CDATA[
  307. <p>Ukraine has destroyed a significant portion of Russia&#8217;s bomber forces in a daring drone attack deep inside Russia. Ukraine&#8217;s security service, the SBU, launched hundreds of drones near four air bases in Russia and destroyed 41 heavy bombers, many of which had been used in long-range missile attacks against Ukraine in recent weeks. According to Kyiv Independent, the single coordinated attack caused $7 billion in damage and took out 34% of Russia&#8217;s cruise missile launch platforms. Among the planes hit were A-50s, Tu-95s and Tu-22M3s, some of the most modern in the Russian inventory.</p>

  317. <p>Once the bombers were burning, Ukraine apparently had no qualms about bragging about how they did it. A source told the Independent the drones, each equipped with POV cameras that live-streamed their flights, were smuggled into Russia in an operation that started about 18 months ago. They were taken to staging area near the air bases, including one in Irkutsk, about 2500 miles from Ukraine, and hidden in the joist spaces of dummy cabins. The cabins were mounted on trucks and moved into position. &#8220;At the right moment, the roofs of the cabins were opened remotely, and the drones flew to hit Russian bombers,&#8221; the publication reported. </p>

  344. <content:encoded><![CDATA[
  345. <p>President Donald Trump has confirmed previous reports that he&#8217;s withdrawing Jared Isaacman as his pick to lead NASA. Isaacman, a billionaire who owns a credit card processing  company, was about to go for his Senate confirmation in the next few weeks. “After a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA,” Trump said in a Truth Social post late Saturday. &#8220;I will soon announce a new Nominee who will be Mission Aligned, and put America First in Space.” </p>
  346.  
  347.  
  348.  
  349. <p>Trump did not elaborate on what specific &#8220;prior associations&#8221; were found to sour him on Isaacman, but Isaacman is a close friend of former Department of Government Efficiency (DOGE) leader Elon Musk, who left that post on Friday. Musk championed Isaacman for the NASA job and appeared critical of the decision to drop him. “It is rare to find someone so competent and good-hearted,&#8221; he said in an X post.</p>
  350.  
  351.  
  352.  
  353. <p>Isaacman did not comment directly on the decision but did say his experience as the nominee was positive and showed him the vetting is done by “many competent, dedicated people who love this country and care deeply about the mission.<strong>”</strong> That dedication &#8220;was on full display during my hearing, where leaders on both sides of the aisle made clear they’re willing to fight for the world’s most accomplished space agency.” Isaacman bought a series of SpaceX trips to space, one of which included the first private spacewalk.</p>

  377. <description><![CDATA[Court rules it's "premature" to force the sale of unleaded avgas in California]]></description>
  378. <content:encoded><![CDATA[
  379. <p>A California judge has ruled that GAMI&#8217;s G100UL unleaded avgas is not &#8220;commercially available&#8221; and therefore FBOs and distributors in California cannot be compelled to sell it, particularly to the exclusion of 100LL. Judge S. Raj Chatterjee, of the California Superior Court also said that in order to achieve that status, G100UL needs  to be universally available to all gasoline powered aircraft  and have &#8220;general consensus&#8221; from the industry and potential customers that the fuel is safe and appropriate for their use. Chatterjee was ruling on a motion by the Center for Environmental Health to enforce a 2014 consent agreement that settled its lawsuit against 26 FBOs and four fuel distributors concerning the environmental and health impacts of leaded aviation fuel. The agreement says that the FBOs and distributors must sell a lower lead alternative that is &#8220;commercially available&#8221; but the judge says it&#8217;s &#8220;premature&#8221; to find that G100UL meets that requirement. The full ruling is copied below.</p>
  380.  
  381.  
  382.  
  383. <p>&#8220;The Court finds that CEH has not met its burden at this time to demonstrate that G100UL is “approved for aviation use” and &#8216;Commercially Available.&#8217; This Order does not minimize the health hazards of lead in the air. This Order decides only that CEH has not demonstrated thatG100UL is &#8216;approved for aviation use&#8217; and &#8216;Commercially Available&#8217; to the Settling Defendants in the California market, which under Consent Judgment para 2.3.1 would require each Settling Defendant to “purchase [G100UL] for resale, distribut[ion], and [sale] in California,&#8221; the judgment says.</p>
  384.  
  385.  
  386.  
  387. <p>&#8220;This motion is premature. The science of aircraft fuel will continue to develop.  G100UL is new on the market. CEH has not established a record presented to this Court on this motion in the face of the significant opposition to find that it is “commercially available” at this time. &#8230;. This order does not preclude CEH from raising the issue again as the science and industry advance.&#8221;</p>
  388.  
  389.  
  390.  
  391. <p>Chatterjee said although G100UL is now available for sale at two California airports and can be produced in sufficient quantity to supply the market, potential issues with material compatibility and the fact that most engine and aircraft OEMs, industry associations and fuel companies are unwilling to accept the fuel for use in their products had to be considered in the broad context of such a fundamental change to the general aviation industry. &#8220;The Court finds that the declarations by the independent OEMs and trade groups are sufficiently credible to make the findings set forth herein,&#8221; the judgment reads.</p>
  392.  
  393.  
  394.  
  395. <p>And although he doesn&#8217;t explicitly say it in his ruling, Chatterjee suggests the FAA&#8217;s granting of a Supplementary Type Certificate to allow the use of G100UL in aircraft covered by the STC is not enough on its own to achieve the kind of consensus that meets the needs of the industry. He appears to suggest that the lack of an ASTM International fuel specification for G100UL is a serious flaw in acceptance of the fuel necessary to create the demand that is a fundamental requirement for commercial availability.</p>
  396.  
  397.  
  398.  
  399. <p>GAMI Founder George Braly said the decision was expected based on the preliminary ruling the judge issued several months ago and he said it&#8217;s another delay in moving toward a transition to unleaded fuel that now has a hard deadline of 2030. Innospec, the only company in the world that legally makes tetraethyl lead, has said it will stop making the additive by 2030 in sync with the FAA and EPA&#8217;s deadline for eliminating lead in aviation fuel. </p>
  400.  
  401.  
  402.  
  403. <p>Braly also noted that there was a lot of conflicting testimony between affidavits used as the sole evidence in the proceeding and neither side was able to question that evidence. &#8220;Had the testimony been subject to cross-examination, it is rather likely the Court would have ended up with a very different set of “evidentiary facts”, upon which to base its opinion, and the outcome would have, in this old lawyer’s opinion, been very different,&#8221; Braly said.&nbsp;&nbsp;</p>
  404.  
  405.  
  406.  
  407. <blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
  408. <p>Braly said GAMI&#8217;s contracted refiner Vitol will continue to supply fuel to the two California airports along with one in Tupelo, Mississippi and another near Houston currently selling it and will be looking for new outlets while the FAA-led Eliminate Aviation Gasoline Lead Emissions (EAGLE) fuel evaluation and validation process continues.</p>
  409. </blockquote>
  410.  
  411.  
  412.  
  413. <p>The National Air Transportation Association, which spearheaded the legal battle against the CEH motion, applauded the ruling saying it recognized the broad impacts of the case and the need to proceed with the transition to unleaded avgas with concern for all the various interests. &#8220;The decision underscores that the introduction of a new aviation fuel must occur through a transparent, consensus-driven process that pursues environmental goals without sacrificing safety or the operational feasibility for both the general aviation community and aviation business sector,&#8221; NATA said in a statement.</p>
  414.  
  415.  
  416.  
  417. <p>AOPA President Darren Pleasance said his group is glad that the supply of 100LL will go uninterrupted in California. &#8220;AOPA was pleased to see the courts recognize the importance of ensuring continued availability of 100LL at California airports while we all work with the industry to navigate a safe transition to an unleaded future,&#8221; he said.&nbsp; &#8220;Prematurely forcing any unleaded fuel that is not yet fully tested across the existing aviation fleet adds unacceptable safety concerns.&#8221;</p>

  447. <content:encoded><![CDATA[
  448. <p>All the usual authorities are investigating a May 13 incident at San Francisco International Airport in which a United A320 apparently turned in front of a SkyWest CRJ 200 while both were taking off from parallel runways. According to statement by one of the air traffic controllers working that afternoon that was sent to VASAviation, the United plane, which was taking off from Runway 1R, was supposed to turn right and the CRJ was supposed to turn left. Instead, the United plane made a sharp left almost directly into the path of the CRJ. The planes came within 0.4 nautical miles laterally and 200 feet vertically.</p>
