Schmite,
Before you get your feathers too ruffled, you will note that I did not mention anyone by name. I generalised which is exactly what everybody else on this thread has done. Despite your protestations, not every engineer (or mechanic if you wish to be pedantic) is beyond reproach. Similarly I suggest you re-think your assertation that 'NOBODY ' in the offices could teach an engineer to read an IPC. There are many many people on the hangar floor who would never make a mistake whilst reading IPCs but I categorically assure you that there are also many many people there who absolutely cannot accurately sort out part numbers and transfer them to demands. Are you so sure that everybody in the offices is totally ignorant of engineering principles and practice? You are badly damaging your own case by such arrogance. Anybody who works in this Industry and considers themselves to be beyond reproach requires an object lesson in humility. My several decades of involvement has at least taught me that one should never underestimate the abilities of others. Schmite, I do not doubt your own abilities nor your integrity for an instant. Please do not underestimate the abilities of others.
