Aircraft involved
Probable cause & findings
The pilot’s failure to maintain clearance from telephone wires while on final approach for landing which resulted in a collision.
Factual narrative
The pilot reported that while on final approach for landing, the airplane struck telephone wires. The pilot maneuvered the airplane to the ground and shortly after touchdown, the airplane nosed over. The right-wing lift strut and rudder sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
