I heard a rumour that should the AD go through, we will only start receiving cranks 12 months from now :(
Anyone else with first hand info on this? Would?ve loved to get back in the air after lockdown as we aren?t allowed to fly during our lockdown in South Africa. Frustrating to say the least! |
Interesting, can you share the source of that information? But it doesn't surprise me...my engine builder says there are a limited number of companies producing crankshafts for Lycoming, Superior and ECi.

So don?t quote me on this as it is far from first hand info, but hopefully it won?t take as long. If the risk was negligibly small, I would?ve been flying by now. But not sure what the risk is. |
My day job is in oilfield compression, and we are having a hard time sourcing crankshafts for our compressors as well. There are just a small number of shops with the ability to do this work, and things get backed up sometimes. I can only imagine the headaches the FAA process would add to that.

I accessed the AD proposal and docket and it was lacking in detail information/documentation for the determination of root cause. Nothing on the engine specifications or hours. One failure was 1/4" subsurface, which screams metallurgy and/or heat treat to me. I can not see how a surface site layer has anything to do with that. 99% of all part loading have peak stresses on the surface of the part. |

So has this actually turned into an AD now? Or is it still in the NPRM stage?
|
Still an NPRM.

The 60-day extension period has come and gone. Any news from the FAA or Superior regarding the matter?
Does anyone know if Superior has been working on this? (not sure what the conditions in the US currently is with regards to lockdown etc from COVID-19) |
