DH8D / B735, Exeter UK, 2009

Summary
On 30 October 2009, a Bombardier DHC8-400 departing Exeter at night failed to stop as cleared at the runway 08 holding point and continued onto the runway on which a Boeing 737-500 had just touched down on in the opposite direction. The Investigation attributed the DHC8-400 crew error to distraction arising from failure to follows SOPs and poor monitoring of the Captain taxiing the aircraft by the First Officer. The failure of the DHC8 crew to immediately report the occurrence to Flybe, which had resulted in non-availability of relevant CVR data to the Investigation was also noted.

Description

On 30 October 2009, a Bombardier DHC8-400 being operated by Flybe on a scheduled passenger flight from Exeter to Edinburgh failed to follow its acknowledged ATC taxi out clearance to the runway holding point 08 and entered and lined up on the active runway at night in normal visibility at the same time as a Boeing 737-500 being operated by Astraeus Airlines on a non revenue positioning flight to Exeter, was landing on the opposite (26) direction of the same runway. The landing B737 was able to stop before reaching the other aircraft and clear the runway.

Investigation

An Investigation was carried out by the UK AAIB. It was established that the DHC8 had received and correctly read back taxi clearance to Holding Point A1 for a departure on Runway 08. However, the crew had subsequently crossed Alpha One and lined up on Runway 08; as they did so, the Boeing 737 landed on Runway 26.The relative positions of the two aircraft just prior to and during the incursion by the DHC8 are shown below.

It was concluded that “the (DHC8) co-pilot was not adequately monitoring the commander” and that a concurrent discussion between the pilots about an earlier departure that day from the same airport was “likely to have conditioned (the crew) to expect the same clearance from ATC on (the incident) sector. It was also noted that the aircraft commander had asked for the ‘Line Up’ Check List despite the Taxi checklist not having been completed. It was considered by the investigation that “all of these factors (had) led the crew to become distracted enough to (exceed their taxi clearance limit)”.

It was noted by the Investigation that Exeter Airport does not have red stop bars and that UK Aerodrome Licensing requirements only specify their provision at Holding Positions intended for use in RVR conditions less than 800 m, which did not apply to A1.

It was also noted that, contrary to the requirements of the Flybe Operations Manual, the flight crew had continued to operate both the flight from Exeter to Edinburgh and the subsequent return flight to Exeter after the Incident and that a report of the event had not been filed by the crew with the Operator until the day afterwards or promptly notified by ATC to the AAIB at the time. As a result, the incident portion of the CVR had been overwritten.

The Final Report of the Investigation was published on 11 November 2010. No Safety Recommendations were made.
