Introduction
On 1 June 2022, a Piper PA-34-200T (registration G-CAHA) was conducting a final training flight for a multi-engine pilot (MEP) course at Dundee Airport. The aircraft was built in 1977 and was powered by two Continental Motors Corp TSIO-360-EB piston engines. The flight carried two crew and one passenger; all occupants escaped without injury.
Incident Sequence
The aircraft was on final approach when the downwind checks were completed, and the student pilot confirmed that the landing gear was down and locked with three green lights. The instructor described the subsequent landing as normal. However, after touchdown, the aircraft began to wobble, listed to the right, and the right propeller and right wing struck the runway. The instructor immediately took control, managed to keep the aircraft reasonably straight, and brought it to a stop. Upon exiting, it was clear that the right main landing gear had collapsed.
Post-Accident Examination
Engineers from the maintenance organization responsible for the aircraft checked the entire hydraulic and electrical system but found no fault. Despite repeated selections of the landing gear, there was no evidence of failure of the main and nose landing gear down lock safety mechanism and switches. The aircraft was subsequently written off by the insurers and was not repaired.
Conclusion
The source does not state a probable cause for the landing gear collapse.
