Occurrence
On 13 June 2013, an Embraer 170 aircraft was departing from Warsaw Chopin Airport (EPWA) operated by LOT Polish Airlines. During the takeoff roll, after the crew set the engine thrust levers to takeoff power, the Engine Indication and Crew Alerting System (EICAS) displayed a BLEED OVERPRESS (bleed 1) message. In response, the flight crew decided to reject the takeoff. The aircraft had accelerated to a maximum calibrated airspeed of 21 knots at the time of rejection.
After vacating the runway, the crew consulted with the Maintenance Control Center (MCC). The captain then performed a reset of the cabin pressure system. The warning indication disappeared, and the captain decided to continue the flight. The fault did not recur during the remainder of the operation.
Investigation
The investigation was conducted by LOT Polish Airlines under the supervision of Maciej Lasek from the State Commission on Aircraft Accident Investigation. The group did not appoint a formal investigation team. The final report was issued on 18 August 2015. No safety recommendations were formulated.
Cause
The stated cause of the incident was a false BLEED OVERPRESS signal.
