OK. This my third attempt to post this must be me! Late night long trip v/tired pitch black. At last home in sight short runway no wind. I always teach do not lower flaps during the turn why? well its not necessary shows poor planning,and what if the flap on the down wing were to fail.So there I am half flap on base turn on to final wings level 450 ft. lets select full flap 50% PA 23 then bang and the PAPIS look at a strange angle!
TRY FULL PWR ON PORT ENGINE no good now 60 deg bank lets undo last thing I did raise flap .As they are hydraulic the stbd flap goes to 10 deg with a bang then all the way in. wow! now about 50ft lets go round and try again. PROBLEM WAS BROKEN TORQUE TUBE NOT UN COMMON. BUT WHAT IF I WAS AT 30 ANGLE OF BANK WHEN IT WENT GUESS I WOULD NOT BE TELLING YOU THIS. Moral why do something that is totaly unnecessary?
