NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
THE PIPER AIRCRAFT, N1038U, DEPARTED FROM RUNWAY 32 AT THE MUNICIPAL AIRPORT, WHARTON, TEXAS, ON A NORTHBOUND FLIGHT, ABOUT TWO MINUTES AFTER THE CESSNA AIRCRAFT, N4745U. ABOUT 10 MINUTES LATER THE TWO AIRCRAFT EXPERIENCED A MID-AIR COLLISION ABOUT 16 NAUTICAL MILES NORTH-NORTHWEST OF THE DEPARTURE AIRPORT. EVIDENCE REVEALED THAT THE PIPER WAS OVERTAKEN BY THE CESSNA. INITIAL IMPACT OCCURRED WHILE THE LONGITUDINAL AXES OF THE TWO AIRCRAFT WERE ABOUT PARALLEL AND THEIR MAGNETIC HEADINGS WERE NEAR THE SAME. THE LONGITUDINAL CENTERLINE OF THE PIPER WAS SLIGHTLY ABOVE AND SLIGHTLY RIGHT OF THAT OF THE CESSNA, HOWEVER, IT WAS MOVING SLIGHTLY LEFT OF THE CESSNA'S FLIGHT PATH. UPON IMPACT THE CESSNA PITCHED UP AND OVER THE PIPER, HOWEVER, ITS WEAKENED FUSELAGE (DUE TO NUMEROUS SLASHES FROM THE PIPER'S LEFT PROPELLER) FOLDED AND SEPARATED. THE SEPARATED SECTION REMAINED UNDER THE PIPER'S LEFT WING THROUGHOUT THE REMAINDER OF THE ACCIDENT SEQUENCE.
The National Transportation Safety Board determines the probable cause(s) of this accident to be:VISUAL LOOKOUT..INADEQUATE..PILOT OF OTHER AIRCRAFT
