At one time there were counterfeit bolts bring slipped into the market. Something about the cheaper bolts being stamped as #12s or something like that. I wonder if there are still some around. You don’t often read about engines falling off. But counterfeit bolts would do the trick.
“At one time there were counterfeit bolts bring slipped into the market.”
When I was in A&P school in 96’ they warned us about Chinese fakes back then.
True about the bolts but the investigation is tracking cracks in the pylon mounts, not the bolts.
I think it was as that they used a forklift to change the engine rather than the GE advised method involving a sling or some such. They may have ditched the approved method. This has resulted in a crash I think once before.
