FAA accidentally sent their unredacted investigation report into the premature G4 rotation in May 2015

"On May 12th 2017 the FAA accidentally sent their unredacted investigation report to the Tampa Bay Times, however, without any photos mentioned in the file. The report states, that the maintenance service provider to Allegiant, AAR Aircraft Services Incorporated, had performed maintenance on the aircraft on May 23rd 2015 by installing an overhauled “left elevator boost control cylinder” Serial Number SRT001. Following the incident the FAA inspector verified, that the unit then installed on the aircraft and following the incident removed from the aircraft was the same that had been installed on May 23rd 2015. As part of that maintenance task it was also necessary to perform a weight and balance on the left hand elevator, "which required that the left elevator (and tabs) be removed and reinstalled, which was found to also affect the rod end for the elevator power control boost cylinder, as the castellated nut must be removed from the elevator power control boost cylinder rod end in order to remove the elevator."

Is Allegiant still using AAR Aircraft Services for MX work or a new company?

Allegiant uses AAR for MD80s.

I do hope that the G4 bashers that frequent this website will note that this was an AAR failing

It's only one inspector's opinion, and was basically-overruled by his superiors.

However, the reason it was overruled was a "new policy" by the FAA to use fines only as a last resort, and instead to work with the offender to get them to own up to the error and take corrective action, rather than litigating. I think the issue is that while this is well-intentioned, it appeared to the inspector that AAR had been caught previously with failures to inspect and that the company culture was to just ignore inspections and get the aircraft out the door.

Had the airplane crashed, there would have been a white-glove team all over the place at AAR, it would have been shut down for a while, and all sorts of hand-wringing would have taken place. But since nobody died, the FAA wrote it off.

And here's the rub: at an airline, inspecting is the last step, one that the company is happy to finance to ensure the safe operation of its airline. At a vendor, while in the long run it's a good thing to do, at the micro level it's just an expense.

What is most concerning is that the AAR work plan called for FIVE -- that's FIVE, one more than four, two more than three -- FIVE separate inspections to check that that cotter pin was installed. And the AAR technicians plainly never performed at least some of those inspections, and AAR released the aircraft despite multiple failures of AAR employees to fill out the paperwork showing that those inspections had taken place. In short, they failed to inspect, their own documentation shows that they failed to inspect, and AAR released the aircraft. Upon inquiry, it appeared to the very-experienced inspector that AAR's safety culture was to fudge these things, and he found multiple other examples of the same failures taking place, even after the vendor claimed to have taken corrective action regarding past violations of the same nature.

That's what made him lose his mind and recommend the maximum fine.

And that's what his superiors overruled.

I'm thinking that the failure to inspect is often the thing that ends up in tragedy. That Executive Air prop that had been misrigged suffered from exactly the same issue. Everyone died. Emery. Everyone died. Etc.

I am all for regulators working with vendors to effect safety change, but where the vendor's culture is defective and proven to be so despite efforts at change, one has to pull out the stick. Because for some folks, all they understand is punishment.

I wonder what the issue is with AAR at OKC? He states in his summary at the bottom that he feels AAR-OKC has a systemic culture of disregard for safety and maintenance procedures. AAR OKC has been doing heavy MRO work for Alaska Airlines for several decades, and Alaska has a pretty good safety record and doesn't seem to have any of the same issues that Allegiant has been having. They also do work for Mesa Airlines, and they haven't had any of these issues.

Same company, same location, same workers, same management -- different outcomes. YV, G4, and AS all use the same vendor in OKC for heavy maintenance, yet only G4 is having the issues.

I wonder if Alaska pays better and therefor gets the more senior employees. Not sure if that is how it works in that industry or not.

Yepp, but reading part III is really scary. You don't write such things into a official report if there is no smoke....

Nope, at least not in my company.

What's your point? Instead of doing maintenance in-house and paying union wages, we contract to the lowest bidder.

Just like Southwest sends their planes to Latin America for heavy MX and most majors do heavy MX in Asia?

At least this exonerates G4 to a large extent. Curious: does G4 put all of its maintenance out to tender?
