once (and I kid you not) I have had both prop governors
fail on a Twin Otter.

Flying jumpers, right?

A good friend of mine once decided to try and gather engine failure
statistics for Twin Otters used as jumpships. Not easy - most are not
reported, and most DZ's won't give you the time of day when you ask a
question like that. On top of that, operating hours are mostly
guesswork. But jumpers talk, and he knew a lot of them.

Of course the numbers for failures and operating hours in Part-121
Twin Otters are available from the FAA.

Near as he could figure, the failure rate in jumpship service was
about 300 times higher than in Part 121 service.
