    Subject: Whoops - loss of flap pin
    From: "graeme bird" <graeme@gdbmk.co.uk>
    Interesting flight back from Sandown UK this afternoon. It seems I lost a flap pin somewhere (into the tube I think). On takeoff from a bumpy field had a sudden strong port wing down tendency. I assumed the flaps were different and wondered if the mono port wing leg had collapsed. But, I was in the air and when retracted seemed fairly normal. On arrival back at my base strip I tried a few things at altitude and a couple of simulated approaches. It seemed just about controllable if into wind. So I landed in a square field at the end of our narrow strip so it could skew around if required. Phew, all ok, the leg did collapse and it skewed slightly in the last few yards but no grass contact with the prop and no damage to the wing end. I assume that the pin wasn't well locked in and had ratcheted out on repeated use. The tube still controlled the flap but it could move about an extra few degrees and no longer could be extended enough to lock the leg down. Perhaps some big G movement might have flicked it. Keeping that pin lubricated better might be a good idea and some loctite on the threads. -------- Graeme Bird G-UMPY - Mono Classic/XS FFW 912S, Woodcomp 3000/3W CS, trutrak Gemini 2 axis ap, pflarm, ads-b out, 8.33khz, mode S, FP 5, Aera500 &amp; SD on Nexus, 250 hours &amp; 4 years on the Mono, 880 total g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=461309#461309
