My recollection of Clinton McKenzie's article in 'Flight Safety' September- October 1999 of his incident in A36 Bonanza, VH-FIM was simply this: After landing with the undercarriage down and locked, he attempted to retract the wing flaps but misidentified the undercarriage lever, before the squat switches had taken over.
I've flown with Clinton on the odd occasion over the last twenty eight years. And I'm happy to say that I consider him to be the most competent and safe pilot that I've ever flown with. These days, he leaves the wing flap clean up to prior to the engine shut down checks.
Not really sure why there's a few of you out there in PPRuNe land, that hate the guy so much..
