Incident Overview
On March 31, 2015, at EPPO airport, a Bombardier Regional Jet CRJ-900 (CRJ9) was taxiing for departure. The air traffic controller in the tower noticed an unauthorized vehicle on taxiways G and A. After assessment, the controller determined that stopping the aircraft was not required.
Cause
The incident was caused by the vehicle driver's failure to follow the established rules for operating vehicles on the airport's maneuvering area.
Preventive Actions
After a similar incident occurred later, a vertical "STOP" sign was installed at the service road, and horizontal "STOP" markings were painted on the pavement. Additionally, a sign was placed near apron 1 to alert personnel of the proximity to the maneuvering area and the necessity to obtain clearance from the control tower. All airport users were informed of the changed traffic organization and reminded of the maneuvering area rules. The circumstances of this incident were incorporated into periodic training sessions.
Safety Recommendations
The Polish State Commission for Aircraft Accident Investigation (PKBWL) did not issue any safety recommendations following this investigation.
