AAIB investigation to DHC-8-402 Dash 8, G-PRPK
Aircraft de-pressurisation, En route from Edinburgh Airport to London City Airport, 22 July 2019.
Summary:
During a scheduled flight from Edinburgh Airport to London City Airport the CABIN PRESS warning illuminated and the crew initiated an emergency descent. The aircraft diverted to Birmingham and landed without further incident. Following some rectification work the aircraft was returned to service later that day.
During the ensuing weeks the aircraft experienced several more pressurisation events until the operator decided to withdraw it from service for in-depth engineering investigation, after which it was returned to service again. To date no more pressurisation events have been reported.
The operator has taken safety action intended to enhance the monitoring of recurring aircraft faults.
