A Long Time Ago,
Bristow Texas 1979 ish
, We had a maint crew from UK do some work on our Helicopters, seems they did a required sheet metal repair that usually takes 4 to 5 days, these chaps did it over night
. Walla. I being the lucky Aviator, got to run the first AC out of the hangar. Lets see 12%, light off, then Engine Explodes
. Oops............... Wonder where all those rivets went after drilling them out.... Gee MM says remove the engine, then do the repair, guess they missed the first step, and saved all that time.
