Now I am the one rolling around the floor laughing, thanks for making my day. Never did I state they were worth every penny, just highlighting the processes of manufacture of such low volume parts.
Do you know if the new part or the old part is deformed, I would be asking Cessna for the drawing and vaguely recall coming across this before. Maybe that is why they have had a 1,000 hour life since 1978??
Again as LAME's we do not make the rules we are just the grim reapers, a position none of us enjoy. Personally I would not have changed them and continued on the AD until the SID date as per the AAC, in the mean time I would have been looking for a way out by PMA alternative or AMOC via perhaps a SOM writing them out of the SID by repetitive MPI.
