Hi Graeme,
I am glad that you got down safely. I assume you are referring to the pin
screwed into the root of the flap and that you have confirmed that it is
missing. Are you able to confirm that it came unscrewed rather than sheared
off? Although this all ended safely the failure of this pin is a pretty
serious event and it is worth sharing the details so please let Malcolm
McBride or Andy Draper of the LAA know the results of your investigation.
Best regards
Brian Davies

Subject: Europa-List: Whoops - loss of flap pin
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 move!
ment might have flicked it. Keeping that pin lubricated better might be a
good idea and some loctite on the threads.
