What happened
On 12 June 2018, a Cessna 172S, registration G-THYB, was performing local circuits at Cork Airport as part of a flight training program. After completing two circuits under the supervision of a flight instructor, a student pilot was authorized to proceed with a solo flight.
During the second solo circuit, the student pilot approached runway 34. The pilot noted the airspeed was approximately 72 knots, which was considered fast for the approach, and observed that the wind was blowing down the runway. Upon touchdown, the aircraft bounced, briefly becoming airborne again. Rather than initiating a go-around, the pilot continued the landing attempt. This resulted in a series of bounces and pilot-induced oscillations. Ultimately, the aircraft impacted the runway in a nose-down attitude, causing the nose landing gear to partially collapse and the propeller to strike the runway surface. The student pilot exited the aircraft without injury, and no fire occurred.
The investigation
The AAIU examined the flight history, aircraft condition, and pilot statements. The investigation confirmed that the aircraft, a 2006 model, had no mechanical failures prior to the event. The investigation also reviewed the training environment, noting that the student was operating under the instructor's authorization as part of a formal training course. Meteorological data confirmed a wind velocity of 340 degrees at 10 knots, supporting the pilot's assessment of a tailwind component.
Findings
- The aircraft sustained substantial damage, including a partially collapsed nose gear strut and damage to the engine due to propeller shock-loading.
- The student pilot's approach speed of 72 knots was significantly higher than the aircraft's stall speed.
- The failure to execute a go-around following the initial bounce allowed the aircraft to remain at a high energy state, contributing to the subsequent oscillations and nose-first impact.
