Boeing. Boeing alert SB. IF the Boeing SB stated optional, then so be it, but what about FAA regs, Boeing's maintenance Req. And compliance therein along with how ever Ansett's SOM was written under CASA's Reg's.
If Piper states optional?
Please read the whole article. Is it not one of the things that led to its grounding.
It's show cause? It's obligations? It did not have robust engineering direction not to comply. does the excerpts from Piper MM mean optional, they consider compliance Mandatory. All SB's. The very data im directed to, not boeings, for that read the 767 MM for me and let me know.
