Incident Overview
On 13 May 2015, a Ryanair Boeing 737-800 (registration EI-EPH) operating a flight from London Stansted to Kraków-Balice Airport (EPKK) experienced a taxiway incursion incident after landing on Runway 25. The aircraft was instructed to taxi via Taxiway C, then Taxiways B and A1 to its parking stand. However, due to ongoing construction, vehicles were present on Taxiway B6, prompting air traffic control (TWR) to stop the aircraft before that taxiway.
Communication Breakdown
The construction vehicle blocking the taxiway was repeatedly called by TWR via radio but failed to respond, despite having been instructed to monitor the frequency. This necessitated a change in taxi route. In coordination with a marshaller, TWR authorized the aircraft to taxi via Taxiway G, followed by a "Follow Me" car, to parking stand 9L.
Cause
The incident was caused by construction personnel not adhering to the established rules for movement and communication on the airport's maneuvering area.
Preventive Actions
Following the incident, the responsible individual was identified and counseled. Information about the event was sent to construction management. Additionally, the airport conducted a review of the validity of movement area permits for all contractor personnel and re-examined those whose permits were nearing expiration.
