What happened
On 23 December 2009, a Boeing 737-800, registered EI-DHD, was involved in an incident during its landing at Glasgow Prestwick Airport. The aircraft was performing a routine landing when the crew's management of deceleration parameters became a point of interest during the subsequent review of the flight sequence.
The investigation
Following an investigation by the airfield operator and further enquiries by the AAIB, a correction was required to the official record regarding the commander's actions during the landing roll. The investigation established the precise sequence of deceleration commands used by the pilot. Specifically, it was clarified that the commander cancelled the autobrake function when the aircraft reached approximately 100 kt. Furthermore, the investigation confirmed that the pilot engaged reverse thrust at 60 kt. After these actions, the aircraft was allowed to continue its roll to the end of the runway before the crew vacated the taxiway.
Findings
- The commander deactivated the autobrake system at a speed of roughly 100 kt.
- Reverse thrust was selected at 60 kt.
- The aircraft continued its roll along the runway until the end of the pavement was reached before exiting.
