Incident Overview
On 11 August 2015, at Wrocław Airport (EPWR), a Regional Jet CRJ-900 experienced a runway incursion after landing. While the aircraft was taxiing to the apron, construction vehicles performing runway maintenance entered the runway.
Sequence of Events
The decision to begin maintenance work earlier than indicated in the current NOTAM had been coordinated with air traffic control and was preceded by the issuance of an additional NOTAM announcing the earlier runway closure. However, the entry of the vehicle convoy onto the runway was not additionally confirmed via radio communication with the tower controller. This was classified as an unauthorized runway incursion. No actions were necessary to avoid a collision.
Cause
The runway incursion was caused by the construction vehicles occupying the runway without obtaining additional radio clearance from air traffic control.
Preventive Measures
In coordination with air traffic control, it was established that in similar future situations, the runway will be occupied by the maintenance crew only after the aircraft has completed taxiing to the apron.
Safety Recommendations
The investigation commission did not issue any safety recommendations.
