Incident
On 10 August 2014, a Robinson R44 helicopter operated under visual flight rules (VFR) violated the controlled airspace (CTR) of Warsaw Chopin Airport (EPWA). The air traffic controller noticed a radar echo in the northwestern part of the CTR, approximately 7-8 nautical miles from the airport. The target displayed a transponder code of 7000 and was observed at altitudes of 600 and then 700 feet. The incursion did not pose a risk to other air traffic.
Investigation
The Polish State Commission for Aircraft Accident Investigation (PKBWL) classified the event as an incident and assigned it for investigation by the helicopter operator. By the conclusion of the investigation on 4 August 2015, the PKBWL had not received any information regarding actions taken by the operator to determine the cause. The supervising investigator from the Commission attempted without success to contact the operator.
Cause
The PKBWL determined the cause of the incident to be an unauthorized entry into controlled airspace.
