What happened
On 9 June 2006, a student pilot departed Rochester Airport in a Medway Microlights Raven X, registration G-MYVW, for a solo general handling flight. The mission involved practicing stalls and simulated engine failures over the marshlands of the Thames Estordu. The pilot had been briefed to fly within a local area and intended to depart with a full 25-litre fuel tank, providing approximately two hours of endurance.
After the aircraft's expected endurance had passed without its return, instructors initiated a search. The aircraft was eventually located the following day by a Police Air Support Unit helicopter on a beach near the high tide mark. The impact, which appeared to be at a low speed and a nose-down attitude, resulted in 1 fatality. The wreckage showed signs of a hard impact, though the pilot had managed to remove his harness and helmet following the crash.
The investigation
Investigators examined the wreckage and the aircraft's structural components. While the rear flying cables and cross-tube tension cables had failed, testing suggested these were not the primary cause of the accident, as the loads experienced during flight were likely below the failure threshold. The investigation also noted that the cables were of a non-standard fibre-cored construction, and the swaged fittings had been made using a tool not designed for this specific cable type.
Search efforts were complicated by the lack of a flight plan and the fact that the aircraft's dark green livery and black/yellow wing surfaces blended into the marshland. Furthermore, the pilot was not carrying GPS equipment, making his exact route difficult to trace via radar alone.
Findings
- The precise cause of the accident could not be determined due to a lack of eyewitnesses and available evidence.
- The aircraft's impact occurred at a relatively low energy, suggesting the accident was potentially survivable.
- Toxicological analysis indicated the pilot may have used cannabis within hours of the flight, which could have impaired his cognitive functions and motor skills.
- The aircraft was using fibre-cored cables that were improperly swaged due to the use of an inappropriate tool.
