What happened
On 5 September 2010, a Culver LCA Cadet, registration G-CDET, was performing a private flight when it encountered severe turbulence during its approach to Eshott Airfield in Northumberland. During the landing sequence, the pilot struggled to extend the landing gear, a process that necessitated the use of both hands. Although the pilot believed the gear was securely locked, the undercarriage collapsed upon touchdown.
The aircraft skidded along the ground on its underside, causing significant damage to the fuselage, engine cowl, wing, cockpit, and propeller. The impact caused the gascolator, located forward of the firewall, to sustain damage and release fuel. This resulted in a fire that spread into the cockpit. The pilot managed to exit the aircraft with minor injuries, and while using the onboard fire extinguisher, the supply was exhausted before the flames were fully suppressed. Members of the local flying club arrived at the scene and assisted in extinguishing the fire using additional extinguishers.
The investigation
The AAIB investigation focused on the mechanical failure of the landing gear and the subsequent fire. The inquiry established that the pilot's lack of experience operating in turbulent conditions, combined with the lack of a visual indicator to confirm the gear was locked, played a role in the incident. The investigation also examined the positioning of the gascolator, which was vulnerable to damage during a gear-up landing.
Findings
- The primary cause of the accident was the collapse of the landing gear following touchdown.
- The pilot's difficulty in managing the landing gear extension due to turbulence contributed to the event.
- The absence of a landing gear warning or indication system meant the pilot could not verify the gear's status.
- The location of the gascolator made it susceptible to rupture during the skid, leading to the fuel leak and fire.
