Turnabout is Fair PlayI was working with a pilot on his complex endorsement. Complex endorsements are needed for aircraft with retractable gear. A large part of complex training is designed to imbue the pilot with a healthy paranoia about landing gear. There are many ways for Arrow landing gear to fail, or appear to fail. I use them all when training people for complex to make sure they are consciously and constantly checking the gear before landing.
On this particular flight the gear was "failing" often for my student. And he was, indeed, getting paranoid. During the flight I also demonstrated some specialty take offs and landings for him. After we finished the flight he said he had a confession to make.... he had "failed" one of the landing gear on me by pulling out the gear light bulb, but it didn't work because I was also paranoid about the gear (where do you think I got the idea to make my students paranoid?), so I pushed the bulb in as a matter of course on final. We both had a good laugh on that one. And I was very glad that I practice what I preach!
