On May 25, 1991, a Piper J3C-65 (registration N3609K) operated by Sam Riggs was involved in an aviation accident near Claremore, OK. Investigators recorded the probable cause as: THE INSTRUCTOR PILOT (PIC) DID NOT MAINTAIN CLEARANCE FROM OBSTACLES DURING THE MANEUVER. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An instructor and student in a tail-dragger transition training flight struck a 35-foot pecan tree with the right wing's leading edge. The fuel tank ruptured on ground impact, and post-impact fire consumed the aircraft. No pre-impact mechanical failures were found.
Accident Overview
An instructor pilot and a dual student were conducting touch-and-go landings as part of a tail-dragger transition course for a Spanish foreign national who intended to begin agricultural spray school. After departing the airport, the aircraft was observed maneuvering at low altitude approximately three statute miles to the southeast.
Sequence of Events
The aircraft's right wing leading edge struck the upper branches of a 35-foot-high pecan tree. Subsequently, portions of the right wing and tree branches were found below the tree and along the flight path. Upon ground impact, the fuel tank ruptured, and a post-impact fire ensued, consuming the aircraft.
Mechanical Findings
Examination of the airframe and powerplant revealed no pre-impact mechanical failures or malfunctions.
