Accident Overview
On September 26, 1967, a Piper Cub aircraft registered as HB-OEY was involved in an accident at Colombier aerodrome in the canton of Neuchâtel, Switzerland. The aircraft was conducting a dual instruction flight, with an instructor and a student pilot on board.
Sequence of Events
During the final phase of the landing approach, the student pilot abruptly pulled back on the control stick. This action caused the aircraft to pitch up and enter a stall at an altitude of approximately 1.5 meters above the runway. The instructor was unable to regain control and correct the situation. The aircraft subsequently dropped heavily onto its landing gear.
Damage and Injuries
The occupants remained uninjured. The aircraft sustained damage to its fuselage structure.
Investigation
The investigation was conducted by the Federal Commission of Inquiry into Aircraft Accidents under Swiss authority. The report was approved on February 28, 1968, and circulated on April 27 and May 6, 1963 (note: the circulation dates appear to be from a different year, likely a typographical error in the source).
