![]() The logistics company operates a fleet of 28 747-8Fs. GE has also advised operators to introduce a shim check inspection, to ensure the valve port is properly installed.Ĭirium fleets data indicates the freighter was delivered to UPS in November 2020. Operator: UPS - United Parcel Service - N570UP Aircraft: Boeing - 747-400F, ERF Airport: USA - Alaska - Anchorage - Ted Stevens Intl / Kulis Air National Guard Base (ANC / PANC) Category: Main database Photo taken on by JPC van Heijst Camera setting: NIKON D200, 1/250s, f/8. The AAIA has recommended a 100% torque verification procedure that “minimises the likelihood” of an improper installation. UPS FlightPath Intern Train on a specific fleet (B747, B757/767, A300 or MD-11) in aircraft systems, cockpit flows/procedures and SIM training sessions. ![]() “The under-cowl area likely contained components above fuel auto-ignition temperature even after 22 minutes of shutdown,” it says. Investigators believe the in-flight fire was caused by the auto-ignition of leaking fuel as it came into contact with hot engine components.This lasted around 10min in total, the report says.įuel remaining in the under-cowl area after shutdown, likely leaking as a result of “secondary damage” to fuel-carrying components, plus a significantly higher temperature due to the in-flight fire, was sufficient to permit the ground fire, the AAIA adds. Further analysis narrowed the leak that triggered the fire to a loose fuel supply pressure bypass valve port fitting.ĭuring the flight, the incorrect low pressure readings in the FMU caused by the leak were sufficient to cause the engine FADEC to request more fuel to avoid a flame-out, which in turn casued the fan overspeed. Subsequent tests performed on the engine fuel system discovered multiple leaks from the fuel metering unit (FMU), which were eventually isolated to three loose bypass fittings. However, the rest of the aircraft was left undamaged, the report adds. The engine pylon, thrust reversers, exhaust sleeve and cone were all removed and replaced. Thermal damage was sustained to the engine exterior core. From a distance, they all look about the same. Most of the popular Boeing and Airbus passenger jets, like the 767, 747, A330, and A350, have cargo counterparts. ![]() Additional suppressants were applied and the fire extinguished within 40s, says the AAIA. MaAircraft Systems 2 Passenger and cargo aircraft look the same when flying over head. However, 22min later white smoke and then flames were detected emerging from the engine, a GE Aviation GEnx-2B67/P turbofan. The crew discharged two fire extinguisher bottles but the fire warning continued, lasting approximately 9min 30s in total, and ending shortly before touchdown.Īfter landing in Hong Kong at 12:30 local, inspections by the airport’s fire department revealed no fire. Some 12s later, an engine fire alarm was triggered. Despite commanding the engine to idle, it continued to oscillate around the take-off speed/overspeed limit “causing a loss of thrust control”, says the report.Īs a result, around 4min into the flight, the crew opted to shut down the powerplant and return to Hong Kong. Operating as flight UPS3 to Dubai from Hong Kong International, as the 747-8F (N624UP) transitioned from take-off to climb, at about 300ft, the crew received a fan-speed exceedance warning for the left outboard engine. The No.1 engine of an UPS Boeing 747 freighter caught fire as a result of a fuel leak. Airline Business special: CEOs to watch in 2021. ![]()
