An unfortunate but rather typical issue here.
It is less dangerous to have a LOW time pilot fly a Complicated aircraft, then it is for a ULTRA high time commercial pilot fly a SIMPLE Aircraft.
Many moons ago, I was offered a ride in a private jet, flown by "the" company pilot.
The FIRST time the guy touched the yoke was when it was time to rotate.
That told me all I needed to know about this particular pilot.
I booked an airline ticket to get home. Once was enough.
Personally, I would have NO problem to put a Piper Arrow certified pilot in a Mooney.
I'd never put a Mooney pilot in a Jodel without proper training.
Those "know and seen it all guys" are ready for accidents to happen.
