The Primary cause of the accident was attributed to the aircraft taking off with the cover still fitted to the pressure head. The accident occurred at night near the drome with MK1 Drem lighting in force supplemented by double cross Goose Necks, Gum Lamps and Floodllghts. Soon after take off the Captain called up on TR9 to say that the Air Speed Indicator was U/S. As it was a duel controlled aircraft with the Pupil Pilot in the pilot’s seat, the 293 Screened Captain took control, and made a right hand circuit, and overshot badly. He took overshot procedure, but stalled at 400 feet and crashed. The failure of the Air Speed Indicator was attributed to the fact that the aircraft took off with the pressure head cover on. The cover was found tied to the pressure head after the crash. Neither the Captain nor the Pupil Pilot could have carried out their “before flight” drill properly because the removal of the cover on the Pitot Head is the first sequence of the drill. It was not understood why a screened pilot should have done a right hand circuit as he was an experienced instructor who had passed the CFS. Orders have now been given to all Pilots that they are not to take off until the Pressure Head cover has been handed to them. The Group Captain Lichfied Station : “I concur. I have given orders that the Pressure Head cover is to be handed to the Pilot prior to the aircraft taxying out for take off.” The Air Cdre AOC No 93 Group stated: “I concur that the Rigger is primarily to blame for failing to ensure that the Pitot Head cover was off and to make his report to the Pilot. The Pilot was also to blame for failing to check either. Disciplinary action is to be taken against the Rigger.” |
