Shortly after British Airways Flight 5390 left Birmingham Airport in England for Málaga Airport in Spain on 10 June 1990, an improperly installed windscreen panel separated from its frame, causing the plane's captain to be blown partially out of the aircraft. With the captain pressed against the window frame for twenty minutes, the first officer managed to land at Southampton Airport with no loss of life.
Incident
The County of South Glamorgan was a BAC One-Eleven Series 528FL jet airliner, registered as G-BJRT.[1] The captain was 42-year-old Tim Lancaster, who had logged 11,050 flight hours; the copilot was 39-year-old Alastair Atchison, with 7,500 flight hours.[2] The aircraft also carried four cabin crew and 81 passengers.
Atchison handled a routine take-off at 08:20 local time (07:20 UTC) then handed control to Lancaster as the plane continued to climb. Both pilots released their shoulder harnesses and Lancaster loosened his lap belt. At 08:33 (07:33 UTC) the plane had climbed to 17,400 feet (5,300 m) over Didcot, Oxfordshire, and the cabin crew were preparing for meal service. Flight attendant Nigel Ogden was entering the cockpit when there was a loud bang[3] and the cabin quickly filled with condensation. The left windscreen panel, on Lancaster's side of the flight deck, had separated from the forward fuselage; Lancaster was propelled out of his seat by the rushing air from the decompression and forced head first out of the flight deck. His knees were caught on the flight controls and his upper torso remained outside the aircraft, exposed to extreme wind and cold. The autopilot had switched off, causing the plane to descend rapidly.[3] The flight deck door was blown inward onto the control console, blocking the throttle control (causing the aircraft to gain speed as it descended) and papers and debris blew into the flight deck from the passenger cabin. Ogden rushed to grab Lancaster's belt, while the other two flight attendants secured loose objects, reassured passengers, and instructed them to adopt brace positions in anticipation of an emergency landing.
The plane was not equipped with oxygen for everyone on board, so Atchison began a rapid emergency descent to reach an altitude with sufficient air pressure. He then re-engaged the autopilot and broadcast a distress call, but he was unable to hear the response from air traffic control because of wind noise; the difficulty in establishing two-way communication led to a delay in initiation of emergency procedures. Ogden, still holding on to Lancaster, had begun to suffer from frostbite and exhaustion, so he was relieved by chief steward John Heward and flight attendant Simon Rogers.[4] By this time Lancaster had shifted several inches further outside, his head was repeatedly striking the side of the fuselage with great force, and his eyes were open but not blinking. The crew believed him dead, but Atchison told the others to keep hold of him because his body might fly into the left engine and damage it.
Eventually Atchison was able to hear the clearance from air traffic control to make an emergency landing at Southampton Airport, while the flight attendants managed to free Lancaster's ankles from the flight controls yet keep hold of him. At 08:55 local time (07:55 UTC), the aircraft landed at Southampton. Passengers disembarked using boarding steps.
Lancaster survived with frostbite, bruising, shock, and fractures to his right arm, left thumb and right wrist.[3][5] Ogden suffered a dislocated shoulder and frostbite to his face, with damage to one eye. There were no other major injuries.[5] Lancaster returned to work after less than five months and retired from commercial piloting in 2008.[3][5]
Investigation
Police found the windscreen panel and many of the 90 bolts securing it near Cholsey, Oxfordshire.[6] Investigators found that when the windscreen was installed 27 hours before the flight, 84 of the bolts used were 0.026 inches (0.66 mm) too small in diameter (8-32 vs. 10-32; see Unified Thread Standard) and the remainder were 0.1 inches (2.5 mm) too short (0.7 inch vs. 0.8 inch). The previous windscreen had also been fitted using incorrect bolts, which were replaced by the shift maintenance manager on a like-for-like basis without reference to maintenance documentation, as the plane was due to depart shortly.[7] The undersized bolts were unable to withstand the air pressure difference between the cabin and the outside atmosphere during flight.
Investigators found the shift maintenance manager responsible for installing the incorrect bolts and for failing to follow British Airways policies. They recommended that the CAA recognise the need for aircraft engineering personnel to wear corrective glasses if prescribed. They also faulted the policies themselves, which should have required testing or verification by another individual for this critical task. Finally, they found the local Birmingham Airport management responsible for not directly monitoring the shift maintenance manager's working practices.[8] The incident also highlighted a design inadequacy: the windscreen is not of the "plug" type, whereby cabin pressure helps to hold it in place, but is fitted from the outside and so needs many more bolts.[9]
Awards
First Officer Alastair Stuart Atchison and cabin crew members Susan Gibbins and Nigel Ogden were awarded the Queen's Commendation for Valuable Service in the Air; Ogden's name was erroneously missed from the published supplement.[10]
Atchison was awarded a 1992 Polaris Award for his ability and heroism.
