I understand that; but if that turbine blade disinterested; It would've thrown shrapnel everywhere. Like being shot out of the sky. Again, very old plane and lots of hours on those engines. If the engine fans and air frame wasn't x-rayed for micro-fractures - anything could've gave way. They could've justified, in their own minds, the short-cuts by saying it's a cargo plane, not a passenger plane. Unfortunately; I've seen a lot of that too. I'll refuse sign-off, so management will turn to a younger, less experienced person for that sign-off. They become management's favorite and gets promoted. Never seeing consequences for that small short-cut invites more sort cuts and larger bonuses for keeping cost down. It's a vicious cycle. It got so bad, when inspectors were around, management would give me the day off with pay - so I wouldn't 'accidentally' run into an inspector or talk to them. I eventually got out of there, on my own terms - and I knew management wouldn't "bad-mouth" me, because I knew where all the 'bodies' were buried and I knew my way around the database, so I could've dug up even more dirt.. Boeing already got caught twice, in a decade.
Engine manufacturer GE may have a hot seat next to UPS' maintenance management team. I would reject the idea that cargo planes should maint less. If anyone asked They share common airspace and some do take off with a bellyful of jet A.
Engine casings are designed, and supposed to, contain these blade failures. Not spit them out the side. Yes, I'm aware that sometimes it doesn't work. This plane had its most recent heavy maintenance, the D-check, last month.
Wow, the D-check! That takes 'everything' apart for examining. If any planes have ever augured in a month after D-checks, they must be few in number.
The seat ain't that hot for a cargo plane because you aren't talking about thousands of loved ones grieving over hundreds killed. This is also likely what executive told themselves when the cut corners with their airplane maintenance standards.
