Narrative
On June 19, 2016, at 14:20 UTC, a Cirrus SR22 was taxiing for departure from Runway 29 at Warsaw Chopin Airport (EPWA). The pilot requested a full-length departure and was instructed by ground control to line up on Runway 29 via taxiway E3. However, the aircraft entered Runway 29 via taxiway N3, crossing an illuminated stop bar set to level 3 and disregarding both vertical and horizontal "NO ENTRY" markings. The pilot subsequently reported a need to delay departure, which may have affected his situational awareness at the intersection of taxiways N3 and E3. The pilot stated that neither he nor the other pilot on board observed the "NO ENTRY" signs or the stop bar, and they were unaware of the incursion until contacted by the State Commission on Aircraft Accident Investigation (PKBWL).
Investigation
The investigation utilized audio recordings and determined that no information about the runway incursion was broadcast for preventive purposes. Weather conditions were CAVOK.
Probable Cause
The probable cause of the incident was human error, specifically loss of situational awareness and lack of orientation.
Preventive Actions
The investigating body recommended the following actions: remind controllers of their obligation to report runway incursions, review AIP records regarding the prohibition of crossing activated stop bars, rebuild the approach to threshold 29 (dual entry), and implement Advanced-Surface Movement Guidance and Control Systems. No safety recommendations were formulated by the commission.
