TOMBALL, TX, USA
N2379V
PIPER PA-38-112
THE AIRPLANE WAS BEING USED FOR TOUCH AND GO LANDINGS BY AN INSTRUCTOR AND A LOW TIME STUDENT. IT WAS ON A BASE LEG TO LAND TO THE SOUTH WHEN THE INSTRUCTOR TOLD THE TOWER SHE HAD LOST THE ENGINE AND WAS GOING DOWN. THERE WERE NO WITNESSES TO THE ACCIDENT. THE STUDENT SURVIVED BUT DID NOT REMEMBER THE FLIGHT. NO PROBLEMS WERE FOUND WITH THE ENGINE OR FUEL SYSTEM WHICH WOULD HAVE PREVENTED THE ENGINE FROM PRODUCING ENOUGH POWER TO PREVENT A FORCED LANDING. THE PROPELLER CAME OFF THE CRANKSHAFT AT IMPACT. MARKS ON THE SIX PROPELLER FLANGE BUSHING INDICATED THE PROPELLER HAD BEEN LOOSE FOR AN UNDETERMINED LENGTH OF TIME. THE FLANGE BUSHING HAD BEEN OVERSTRESSED AND THE FLANGED ENDS SEPARATED FROM THE BUSHINGS. THE BUSHINGS CAME OUT OF THE CRANKSHAFT AT IMPACT. THE FIELD WHERE THE AIRCRAFT CAME TO REST WAS SURROUNDED BY TREES.
