Heres one for you, I always taught do not lower flap in the turn.a. because its not necessary shows poor planning.b, It could have serious results,hear`s how. Late night long trip tired home at last, pitch black, the short runway no wind.NO PROBS. Ha a/c PA23 bit old but just off CofA. half flap on base as norm 500 turning onto final, all ok roll out 400 ft. lower rest of flap, could of done it in turn to save time but no, 50 deg of flap just hits the stop and bang instant flap retraction on port side.Opps PAPIS look a bit funny from this angle.Like 60 deg of bank and alti looking at 250 ft. Try full pwr on port engine then automaticaly somehow undo last thing I did that was to raise flap. luck was with me cos hydraulic flaps instantaly retractid to 10 deg. on stbd.making things easier.What if in my left turn to final port flap gave out. No chance, What happened? torque tube failure not cracked tested on CofA OOPS Oh well lower flap in turn if you wish just have lots of height bye bye
