Some years ago I sold my Mooney aircraft to a somewhat rural aviator and undertook the task of giving him a type rating on it as part of the sale.
He had good handling skills but lacked discipline and attention to detail.
As he had never flown a retractable, or V.P. aircraft and refused to use a check list I drummed into his head the need to carry out a CUP (Cowl Flaps, Undercarriage & Pitch) passing 300ft on finals.
A few months later he flew into my local strip, and on wandering over to have a chat and a look at the aircraft I noticed a tin mug hanging from the instrument panel.
When I asked the reason for it, the reply was, "It's a reminder to do the Cup Check",
To this day he hasn't landed with the wheels up
