Summary
On 1 June 2014, a Cessna 152 experienced an engine malfunction during takeoff at Krosno Airport (EPKR). The incident was classified as an incident by the Polish State Commission for Aircraft Accident Investigation.
Narrative
Prior to departure from Rzeszów Airport, the engine was tested and parameters were found normal. After landing at Krosno, the aircraft taxied to the hangar and the engine was shut down. After several minutes, the engine was restarted and the aircraft taxied without issues. During the pre-takeoff magneto check on the runway, parameters were normal.
When the throttle was opened for takeoff, the aircraft moved approximately one meter before the engine began to choke. The throttle was reduced. Upon increasing throttle, engine rpm initially rose but then dropped sharply below 1000 rpm. The engine ran very unevenly.
Investigation
The investigation was initiated based on the occurrence report. However, it could not be completed because the aircraft was returned to its owner, and the individuals involved were no longer associated with the local aero club. The aero club stated that it could not obtain further information beyond the initial report.
Cause
The probable cause was determined as uneven engine operation for unspecified reasons.
