What happened
On 12 March 2001, a Cessna 172N, registration G-OZOO, was conducting a solo private flight departing from Lydd Airport. While flying locally to the east, the pilot became aware of developing weather conditions at Lydd, including an active storm cell and reports of low visibility and turbulence from other aircraft. Consequently, the pilot elected to divert to Kent International Airport (Manston).
Upon joining the left-hand circuit for Runway 28, the pilot noted that the prevailing winds would create a significant crosswind component. During the final approach, reports of turbulence from a preceding aircraft were received. The aircraft touched down normally at approximately 65 kt with 20 degrees of flap set. However, immediately after closing the throttle, the right wing dropped abruptly, causing the aircraft to veer toward the right. The pilot initially suspected a tyre burst on the right landing gear. Despite attempts to use left rudder and braking to maintain the runway centreline, the aircraft exited the runway onto the adjacent grass. The pilot successfully taxied the aircraft back to the runway before shutting down the engine and awaiting emergency services.
The investigation
The investigation was based on the aircraft accident report submitted by the pilot. Examination of the aircraft following the incident revealed that the propeller had sustained damage due to a strike on the tips.
Findings
- The aircraft departed the runway surface due to a violent crosswind gust associated with an approaching storm front.
- The incident occurred shortly after the aircraft had completed its landing roll.
