Accidents & Serious Incidents involving DC93
- DC93 / B722, Madrid Spain, 1983 (On 7 December 1983, a Boeing 727-200 taking off from Madrid in thick fog collided at high speed with a Douglas DC-9 which had not followed its departure taxi clearance to the beginning of the same runway. The DC-9 crew did not advise ATC of their uncertain location until asked for their position after non-receipt of an expected position report. The Investigation concluded that flight deck coordination on the DC-9 had been deficient and noted that gross error checks using the aircraft compasses had not been conducted. The airport was without any surface movement radar.)
- DC93, en-route, Cincinnati OH USA, 1983 (On 2 June 1983, a DC9 aircraft operated by Air Canada was destroyed following an in-flight fire which began in one of the aircraft’s toilets. 23 passengers died in the accident.)
- DC93, en-route, north west of Miami USA, 1996 (On 11 May 1996, the crew of a ValuJet DC9-30 were unable to keep control of their aircraft after fire broke out. The origin of the fire was found to have been live chemical oxygen generators loaded contrary to regulations. The Investigation concluded that, whilst the root cause was poor practices at SabreTech (the maintenance contractor which handed over oxygen generators in an unsafe condition), the context for this was oversight failure at successive levels - Valujet over SabreTech and the FAA over Valujet. Failure of the FAA to require fire suppression in Class 'D' cargo holds was also cited.)
- DC93, vicinity Charlotte NC USA, 1994 (On 2 July 1994, an DC-9 operated by US Air, collided with trees and a house shortly after attempting a missed approach at Charlotte Airport, USA, in heavy thunderstorms. 37 passengers were killed.)
- DC93, vicinity Port Harcourt Nigeria, 2005 (On 10 December 2005, a Douglas DC9-32 operated by Sosoliso Airlines descended below the ILS Decision Altitude without visual reference, on approach to Port Harcourt Nigeria, and control was lost during the attempted initiation of a go around, followed by ground impact and post crash fire.)
