My most "exciting" moment was when the oil filler flap opened up on my C150 whilst climbing out of Popham. Not really a problem, told man on ground I needed priority and side slipped down the approach to try to keep the strain off the flap hinges. Biggest problem was not-to-keen-on-flying girlfriend who had my right thigh in a vice like grip (better than initial grip on upper right arm!!!). Landed off a normal circuit, cured errant flap with a large slice of gaffer tape and took her back up again to prove that it wasn't a life threatening incident.
