Too true Wooms! Reminds me of the CASA FOI that did a 1.9 hour "pencil" Cessna Caravan endorsement.
His subsequent actions confirmed he'd even be unsafe in a Viscount Caravan!!!!!
Same guy did a "pencil" endorsement on a Cessna 310 then on his first flight wanted to US the aircraft after he pumped all the fuel overboard!!!
Yup, you get what you pay for!
$2,000 sounds cheap for a
good PA31 endorsement, particularly if the candidate has low multi time.
