What happened
The incident occurred during a flight where an instructor pilot was demonstrating a barrier or obstacle landing technique. The maneuver resulted in a hard touchdown followed by a bounce upon impact with the runway surface. To regain control and ensure safety, the crew initiated a power recovery procedure. This action effectively terminated the flight phase associated with the landing attempt.
The investigation
Following the landing, the pilots conducted an immediate visual inspection of the aircraft to assess its condition. At that time, no visible damage was identified or reported. However, the situation changed four days later when the aircraft was examined again. According to the aircraft's hour meter records, the plane had not been flown during the interval between the initial inspection and the subsequent discovery of damage.
Findings
The primary factor in this event was the hard touchdown and subsequent bounce during the barrier landing demonstration. The delayed detection of damage suggests that structural issues may have developed or become apparent only after a period of time, despite the aircraft remaining stationary or unused in terms of flight hours.
