Today I had my 3rd Flap failure this summer. All 172's but 3 different airplanes.
1st doing slow flight, 20 degrees flaps deployed, recovered and moved flap selector up, flaps remained at 20 degrees. Cycled the flap switch a few times and flaps finally retracted.
2nd doing Touch and Go's, 20 degrees flaps deployed, decided to do a full stop due to a 757 departing on the parallel runway. Taxiing off the runway went to retract the flaps, they did not retract, cycled flap switch and flaps extended fully but would still not retract.
3rd Today doing touch and goes with 20 degrees flaps deployed, on the go moved the selector to up but the flaps did not retract. Upon landing the flaps retracted.
In 30 years of flying and over 6000 hours I think I can still count flap failures on 1 hand but the # is climbing fast this summer.
Lessons learned...
If flaps won't retract in flight don't do anything that might make them deploy further. There is a good chance you will just end up with more flaps deployed and still not able to retract them.
Yes I like Manual flaps, but one of my previous flap failures was with a manual flap system, a fitting broke and would not allow the flaps to fully retract.
