UPDATED: Adds NAVAIR Letter And JSF JPO, Lockheed Statements

AFA Winter, Orlando: What happens when all the top brass of the Air Force are attending a top conference on a Friday afternoon? Their biggest program, the Joint Strike Fighter, gets its entire fleet grounded because of a crack in a turbine blade. Details began trickling out just as most Air Force brass were headed to the airport after the Air Force Association’s annual conference here ended.

Of course, the F-35 isn’t just the Air Force’s biggest program. It’s the biggest conventional weapons program ever for any country.

Early word is that a low pressure turbine in the engine cracked. The engine is on its way to Pratt & Whitney for a complete check to figure out what happened, why and come up with a fix. We’ve sent emails and called the program office and Lockheed Martin for comment. As soon as it comes in, we’ll update this.

The crack poses “the threat of catastrophic failure,” according to a letter by Naval Air Systems Commander Vice Adm. David Dunaway sent to the Navy Secretary, Chief of Naval Operations, and the Marine Commandant. Dunaway says he will provide an update on the situation no later than March 1, next Friday.

This is not the first grounding of the fleet. The F-35Bs were briefly grounded last month when an improperly crimped hydraulic hose was found in the engine.

Here’s the F-35 Joint Program Office’s statement on the latest problem:

“On Feb 19, 2013, a routine engine inspection revealed a crack on a low pressure turbine blade of an F135 engine installed in a CTOL test aircraft at Edwards Air Force Base, Calif. Engineering teams are shipping the turbine blade to Pratt & Whitney s Engine Facility in Middletown, CT, to conduct more thorough evaluation and root cause analysis.”

They say it’s,”too early to know the fleet-wide impact of this finding, however as a precautionary measure, all F-35 flight operations have been suspended until the investigation is complete and the cause of the blade crack is fully understood. The F-35 Joint Program Office is working closely with Pratt & Whitney and Lockheed Martin at all F-35 locations to ensure the integrity of the engine, and to return the fleet safely to flight as soon as possible.”

Lockheed didn’t say much else, beyond averring that “safety is always our first consideration” and committing themselves to working hard to understand and fix the problem “so the F-35s can safely return to flight as soon as possible.”

This will cost money, of course. The question is, how bad is the problem and is it systemic or a unique problem in this engine. That sound you hear is the grinding of teeth in Lockheed’s headquarters suite.

    It is time to Cancel this monstrosity called the “Junk Strike Fighter” and start the F-22 line back up, and start up-grading our current fleet of F-15C’s to F15S and our F-16 C/D’s to F-16S variants now.

    • expert

      typical AF mentality; can’t see beyond their own self-serving sacred fighter programs. JSF isn’t called Joint for nothing. so if JSF is cancelled, what does Navy do for the carrier jet variant replacement, or USMC VSTOL AV-8 replacement, or those many countries heavily invested in 5th generation JSF?

      • CAMarine

        Yep, your right…that dude was clueless…and I let him know how misguided his statements were…..

      • a99weeker

        As Rummey ince said… you don’t go to war with the Army you want, you go to war with the Army you have (or something like that)… kind of like the Army’s personnel/payroll/leave accounting system called DIHMRS. Over 10 years and 10’s of millions and was not much more than a power-point slide presentation of “what it will do when completed”…

      • http://www.facebook.com/profile.php?id=1258344131 Zbigniew M. Mazurak

        I understand you, but the fact is that the three services’ requirements for combat aircraft are totally different. Marine and Naval strike jets are not fit to be USAF air superiority fighters, and vice versa. This is exactly the #1 reason why the F-35 program has been such a failure: because it attempted to meet all three Services’ needs, and thus, it has produced a “compromise” aircraft that doesn’t really satisfy anyone.

        The USAF should resume F-22 or F-15 production, the Navy should produce more Super Bugs (or upgrade current Bugs) and, in the long term, develop and procure the F/A-XX, while the USMC should retain the F-35B or resume Harrier production.

    • CAMarine

      HEY DUDE, The F22 isn’t engineered to be used by the Navy and Marine Corps PERIOD! I guess you forgot the Navy and Marine Corps do fly the majority of the first strikes off of Carriers…but again, you might be a FLY boy who hasn’t been exposed to the REAL WORD OF FLYING! Your statement is just Laughable!

      • http://www.facebook.com/Recon135 Roberto Benitez

        As a retired AF dude I agree with you. Certainly the AF needs more F-22s, reliable ones, but with the Navy carriers being deployed around the world they need a dedicated fighter that’ll meet their needs as well, and perhaps before the Air Force.

        However, I fear we’re harkening back to the McNamara days and his Switchblade Edsel and trying to deploy an aircraft that will do everything yet satisfy no one.

        Someone who was exposed to the real world of flying

        • CAMarine

          There comes a time, when just because it’s a few years old does it mean we need to replace it….Look the F15 Strike Eagles are still great…and the navy’s F18 Super Hornets are actually the BEST out there….Don’t forget, ALL 3 branches flew the F4 and it had the best winning record of ANY fighter since the P51 Mustang. As far as Macnamara, Chuck Hagel who WILL BE CONFIRMED….and should be….will be a soldiers soldier! And this Marine Officer who happens to be Mustang, would love to see him at the helm !!!

          • http://www.facebook.com/william.moore.9 William Moore

            The F4 was a great attack bomber and interceptor but as a fighter it was mediocre at best. Marine pilots I new referred to it as either a lead sled or a flying dump truck.

        • http://www.facebook.com/profile.php?id=1258344131 Zbigniew M. Mazurak

          Well, the solution, then, is simple: Navalize the F-22, as Air Power Australia has already proposed and shown how to do. Or, better yet, develop and procure the F/A-XX ASAP.

      F-16s are old enough and are barely competitive as it is

      • http://www.facebook.com/profile.php?id=1258344131 Zbigniew M. Mazurak

        But the F-15 can, with cheap upgrades, compete with anything other than the F-22, the PAKFA, the J-20, and the J-31.

    • ran76

      doesn’t the Raptor have its own problems? I believe something about pilots not trusting the plane to keep them alive

      • Doug

        actually yes, they have been having oxygen problems along with other teething problems with avionics. I have always said that both of these birds were piles of junk sitting on tires. maybe I will be proven wrong about one of them but with all the cost over-runs both are costing us an arm and leg along with all the other crap we are being stuck with by osama!!!

    The President will not fix, refurbish, build new or renovate old planes. His plan is to make our country defenseless to other nations, deplete the resources of the people who helped to build our economy and insure his own prosperity and those similar “like servants to the people.”

    • flyboy

      Your crying in the wind. That is the plan and eventually China will take us over.

  • bilk7

    Since they decided to go ahead with the F35, dropping GE’s alternative engine was a big mistake. Monopolies lead to lower quality and higher cost. Also, since all military branches are scheduled to have this fighter in the future…..a crack in the only engine could shut down our entire military!

  • Stilleto

    It is also difficult to pinpoint the cause of crack since the fighter is designed to be stealth! Lol

    • flyboy

      Not a problem since it deals with metalorgy.

      • http://www.facebook.com/frank.j.austin Frank J. Austin

        metal orgy ? Really “flyboy” ? How does a college grad misspell metalurgy ? I presume that you are a military pilot based on your comments. However, I know that military pilots are commissioned officers. To become commissioned, you must obtain a college degree. Has our higher education system failed this miserably ? If so, forget about the “metalorgy”, we have bigger problems…

          Before you preach about someone else’s spelling – it’s “metallurgy” – not metalurgy.

  • veryfrustrated

    F-35 is the Spruce Goose/Flying Folly military aircraft. Numerous flight maneuvers had been performed years ago that proved the F-35 is no better than an Attack aircraft, truth be told the UK, Canada, Israel, and possibly Russia have fighter jets that would fare better in Dog Fights than the F-35. The DOD truly dropped the balled when they moth balled the Raptor project, that is what you get when you think you are going to protect our airspace or that of our allies on the lamb.

    • CAMarine

      Ok Comrade…your definitely a Communist Kool-Aid Drinker!

    • Matt

      FYI the Candians, Brits, and the Israel Air Forces are all under contract to buy the F-35

    • http://twitter.com/Merciful_Wrath General Wrath

      JSF, better look into the flags on the side of some of the models man because oh look, UK, Canada yeah they are there I think Israel is looking to get some too. What kool-aid study was this, made years before the flight of the f-35 that said any were better? sure some may compete but “dog fights” are practically non existent now, its all about detection and weapon range, we got it.

      • Doug

        have you ever really watched clips of any of these birds flying?? hate to say it but I would put the sukhoy mig up against either the f22 or jsf cause that thing will out manuver either of them any day of the week.

    F-16 XL was and is the answer! Same for the F-20 Tigershark! As for the F-35 this plane is junk! Because anyone with a brain cell knows that any plane in service now or experimental that the public is shown, there are aircraft the government and contractors are flying or building that are probably 20 years or more advanced than our latest planes like the F-22 or F-35 in use today! So, there is no excuse for the problems with the F-35!

  • Bass Guitar Hero

    Eh, I prefer the F-22 more myself. And with the constant upgrades to the F-18, each new model is essentially a brand-new fighter, IMO.

    • FranciscodAnconia

      You do realize they are two completely different missions right? The F-22 and F-35 were designed to complement each other. One an air dominance fighter, the other an air to ground platform. They are NOT interchangeable.

      The F-18 is ancient technology compared to the F-35 and is not survivable against modern threats.

      • Bass Guitar Hero

        I don’t CARE whether they’re Navy or Air Force and what YOU think of them. I still like them more.

      • http://www.facebook.com/profile.php?id=1258344131 Zbigniew M. Mazurak

        The F-35 is not well suited to be an air to ground platform either. And it’s not much more survivable against modern threats than the F-18 (which is, of course, ancient technology). It can’t survive in any airspace where the S-300, S-400, S-500, HQ-9, Su-35, PAKFA, J-20, or J-31 are present. It was designed to be a battlefield interdictor pounding massed enemy tank armies and their short-range air defense systems (like the Tor-M1), and only after the F-22 had destroyed enemy air defense systems and established air superiority. As the F-35 JORD spec admits, the F-35 was designed for a world without the S-300, S-400, S-500, HQ-9, Su-35, PAKFA, J-20, and J-31, i.e. a world which doesn’t really exist and never will.

        The F-35 is redundant, useless, and ineffective. Time to terminate it.

  • RJ

    This program has become the MOST expensive fighter program on record and yet Lockheed just asked -and received- an additional $20M to figure out the LAST problem, and now this. It’s time to end this waste of money and have LMCO return the $469 billion we’ve already spent on these fighters. Enough is enough!

    • a99weeker

      Why aren’t these contracts defined to be $xxx million dollars and a specific deadline. Anything needed after the missed deadline is the builders expense, not refundable by the tax payer. Then once “live” and in use (even if used just for training) there is a 5 year FREE fix/replace time frame. Maybe too simplistic, but the taxpayer does not have endless money to keep funding projects that eventually go no where…

      • FranciscodAnconia

        Because firm fixed price contracts are significantly more expensive than cost plus contracts. If you expect the manufacturer to assume all the risk, they charge you significantly more up front to cover unexpected contingencies. If you agree to not hold the contractor to task for every discrepancy, the price tag is significantly less.

    Its time to re-evaluate what the armed forces need as far as high tech devices. I agree with tee, we should cancel the JSG and the F-22 fighters, they were designed for fighing fighters from the Soviet Union. What we need is a fighter that is more a ground support fighter and better equipment for the infrantry and other combat arms. High tech is great but its usually fragile and in the field,, fragile means broken first.

  • pbkittles@aol.com

    Does anyone really beleave Pratt & Whitney or Lockheed Martin would allow this type media unless there was somethin in the back ground they want funded.

    $400 billion dollars for an aircraft that can only fly for short ranges and has no defined combat mission. Are you feeling safer? The next time the military says they need this, that, or the other thing, remember programs like the F-35 are what put our country deep into debt.

  • Michael Parks

    The fact that there are cutbacks on our snow removal by the highway department, who now take longer than ever before to do anything, is linked to the sucking of money from the citizens, and giving it to the “defense” contractors (on a no-bid and cost-plus arrangement at times).
    I’d rather be able to clean the dangerous snow off the road. Bet way more people died on highways in the snow last week, than in crazy-person terrorist shoot ’em ups.
    Maybe we should be getting a rebate from P. & W. and the bunch of ’em.

    f-22 is too much a plane for a human to fly I think is the real problem with it. F-35 is a lot of technology stuffed into a big idea. Then you have companies getting paid off for their close ties instead of their quality of output. And then all the garbage we inport from china that is crap that goes into these.

    This program at this point is said to have reached $400 billion, and its total cost over the life of the program including operational costs was estimated by the GAO four years ago to exceed $1 trillion, so you just know it will be even more than that. Yet the planes seem so fragile that every other day something else goes wrong. Ted Cruz and Lindsay Graham are not only worried about Chuck Hagel kowtowing to their Israeli masters, they are worried that Hagel will take a surgeons knife to these procurement boondoggles and finally put a stake through their heart before they suck more blood out of the economy.

    Another prime example of the waste in the Air Force and DOD. Similar to the V-22 Osprey aka “the Marine Killer”, the F-35 program has been plagued with problems. The Air Force has 50+ different kinds of planes in their inventory which begs the question, why?

    What is needed is a one size fits all fighter that all branches of the Military can use. The Brits have that with the Harrier. Superior US technology can not design a plane like the Harrier?
