皇冠体育app

Summary:

皇冠体育app aircraft suffered a hydraulic system problem shortly before commencing an approach to Blackpool Airport. 皇冠体育app hydraulic pressure fluctuated initially and there was subsequently a total hydraulic system failure, which was not recognised by the crew. 皇冠体育app loss of hydraulic pressure resulted in the speedbrake/lift dump system and power brakes being unavailable, but the emergency braking system remained operational.

皇冠体育app emergency brakes, although available, were not applied during the landing and the aircraft overran the runway at about 80 kt and was extensively damaged. 皇冠体育app occupants, who were uninjured, evacuated without assistance.

皇冠体育app investigation determined that, irrespective of the omission to apply the emergency brakes, the Landing Distance Available (LDA) at Blackpool was insufficient for the aircraft to land with a hydraulic failure. A fatigue crack in the port cap of the left hydraulic pump had caused a hydraulic leak which eventually resulted in the total loss of the hydraulic system.
