CESSNA 172RG

Analysis

THE TWO PILOTS RETURNED TO THE AREA WHERE THEY HAD PREVIOUSLY OBTAINED THEIR PILOT TRAINING AND RENTED THE CESSNA 172RG TO REVISIT THE TRAINING AREAS. THE AIRPLANE'S WRECKAGE WAS FOUND IN A SEMI-REMOTE AREA, STREWN OVER A HALF MILE. EXAMINATION OF THE WRECAKAGE DISCLOSED THE LEFT WING'S WING-TO-FUSELAGE ATTACH FITTING SEPARATED IN AN UPWARD DIRECTION. THE FRACTURE SURFACES DISPLAYED POSITIVE OVERLOAD CHARACTERISTICS. THE UPPER CABIN SECTION AND RIGHT WING BROKE UP AFTER BEING STRUCK BY THE LEFT WING DURING THE INFLIGHT BREAKUP. WEATHER STUDIES REVEALED THAT VISUAL METEOROLOGICAL CONDITIONS PREVAILED. THE AIRPLANE IS NOT CERTIFICATED FOR AEROBATIC FLIGHT.

Probable Cause and Findings

THE PILOT OF THE AIRPLANE EXCEEDING THE CERTIFICATED NEVER EXCEED VELOCITY. THE OVERLOADING OF THE WING ATTACHMENT FITTINGS WHILE MANEUVERING WAS A FACTOR IN THE ACCIDENT.
