Accidents & Serious Incidents involving B748
- B748, Amsterdam Netherlands, 2017 (On 13 January 2017, a Boeing 747-8F arriving at Amsterdam at night in turbulent conditions initially touched down just short of landing runway 36R destroying runway threshold lights and causing minor damage to the aircraft which was subsequently observed after the aircraft had parked. The Investigation determined that a high rate of descent had developed towards the end of a previously stable approach and after this had led to EGPWS Glideslope and Sink Rate Alerts, a go-around was required under operator procedures but was not flown and an insufficient flare then led to a premature hard landing and bounce.)
- B748, Prestwick UK, 2017 (On 30 March 2017, a significant amount of fuel was found to be escaping from a Boeing 747-8F as soon as it arrived on stand after landing at Prestwick and the fire service attended to contain the spill and manage the associated risk of fire and explosion. The Investigation found that the fuel had come from a Bell 412 helicopter that was part of the main deck cargo and that this had been certified as drained of fuel when it was not. The shipper’s procedures, in particular in respect of their agents in the matter, were found to be deficient.)
- B748, Tokyo Narita Japan, 2017 (On 15 July 2017, a Boeing 747-8F close to its maximum takeoff weight only became airborne just before the end of the 2,500 metre-long north runway at Narita after the reduced thrust applicable to the much longer south runway was used for the takeoff and the aircraft cleared the upwind runway threshold by only 16 feet. The Investigation found that the very experienced Captain and the very inexperienced First Officer had both failed to follow elements of the applicable takeoff performance change procedures after the departure runway anticipated during pre-start flight preparations prior to ATC clearance delivery had changed.)
