How exactly do Piper manual flap systems work then? We have a Piper Twin
Comanche with an electric flap system. The flaps are pushed down, but come
back up using springs, in effect after latches are removed. We've now had
two asymmetric flap retractions, where one of the springs failed to do its
job. This is Not Good.

Was this on the ground after landing, or in flight? I'd think that the air
load on extended flaps would help push them up in flight.

It won't. I had one flap not retract once. It just got hung up half way for some
reason. So I just lowered the flaps until they were symmetric and landed.

It helped that it was a test flight and I was in the pattern at the time.
