Alternator coupling let go on a King Air 200 in Wichita last Tuesday
I was doing a routine 100 hour on a King Air 200 in Wichita last Tuesday when the alternator coupling on the left engine gave out after only 400 hours since the last swap. Back in my early days we would just pull the whole unit and send it out, but this time I had a spare coupling in the box and swapped it on the wing in about 90 minutes. Anybody else seeing these couplings fail way earlier than the book says they should?
