    The force of the failure , if not fully contained in a strong rocket could be quite dangerous .

    What is the first picture? Is that the aft end with the holes drilled for a motor retainer?

    Saw this last weekend. Sorry for the issue, was really looking forward to seeing the flight, as I’m sure you were. Hopefully Aerotech takes care of you with a new motor for atleast some consolation.

    Charlie, got my fingers crossed you guys are A) shipping some M1550R's soon (before Labor Day SodBlaster Event) and B) getting close on shipping my warranty replacements.

    Just picked up an M1550 from Wildman, and he still shows them in stock. Chris' Rocket supply has one too. Who is your vendor?
    This is one of my favorite motors, and I've never had a problem getting one.

    It was ordered with the expectation it would be 60 days out (or so), as to who the vendor is he's a small local vendor. Not really to worried about it, my first choice of motor was the M1955DM which so far seems to have failed to certify.

    "The steel U bolt was flattened", wow that's some serious force (and obviously pressure).

    yeah, that suggests a lot more pressure in the motor when it failed than when my M1350 failed on the pad. Higher Pressure implies that the fwd closure was epoxied much more securely. Did you recover the fwd closure and the rest of the motor? When did you purchase the motor?

    I realize this question may have been asked previously, but since business policies can change I will ask at this time…. It has always been my understanding that AeroTech will replace a reload and its case, as necessary, if a reload fails (e.g. CATO) under warranty at no charge. Does this apply to “AeroTech by Dr Rocket” cases as well? Specifically Dr. Rocket cases imprinted the RMS Trademark?

    While not a agent of AT, my gut feeling is Yup. As long as the motor was built according to the directions.

    Charlie aka "ATGM" was last on this thread on 7/24/2019, right now they are attending Hellfire in UT. They don't spend all their time here like some of us.

    Sorry I overlooked that one. Last I saw was maybe from May. Is Charlie the only one person from AT that monitors this thread?

    I've never had any issue having non-AT hardware replaced with a legitimate warranty claim; both Dr Rocket and Rousetech. You might have problems with an unauthorized clone case, that would only be reasonable.

    AT warranty has always worked really well in my experience.

    thx, Good to know, but I'd like to hear it from them too. Obviously a consideration for my first L3 motor for a cert flight and beyond.

    Have you tried emailing their customer support? That would be more appropriate than hoping to catch their attention on a public forum.
    And for the record I do know of instances where they have replaced licensed third party cases with Aerotech hardware as part of a warranty claim.

    Sigh. Maybe you should contact them directly if you feel you need the confirmation.

    Not yet Steve, not in a big hurry, just figured the question has been asked before and someone could direct me to something that was concrete, not anecdotal. But, it is nice to hear a few folks saying it has not been a problem for them. Thanks everyone.

    That’s also been asked before about cross-certified loads, such as a brand X reload in a brand Y case. If there’s a warranty claim and the reload was the problem, the reload manufacturer should replace the damaged case but it will almost certainly be a brand X case, not the original brand Y case. It was discussed at length when non-cooperative cross certification was proposed.

    Had Cato last year with 4 grain 75mm AT reload cross loaded in CTI case. AT covered warranty with new reload & AT case.
