Incident
On 28 July 2015, a Cessna 152 was conducting touch-and-go landings (landing with immediate takeoff) at Lublin-Świdnik Airport (EPLB). After applying power for takeoff, the aircraft entered vibrations. Despite immediately reducing power, the vibrations persisted. The engine was shut down. After consulting the airport tower, the engine was restarted and no vibrations occurred. The aircraft then taxied to the apron. Two occupants were on board; no injuries were reported.
Investigation
The Polish State Commission for Aircraft Accident Investigation (PKBWL) examined the aircraft. The investigation determined that the shimmy damper had a malfunction: its o-ring seal was damaged. The damper was subsequently replaced. No safety recommendations were issued.
Cause
The PKBWL stated that the cause of the vibrations during landing was damage to the o-ring seal of the shimmy damper.
