After performing a high speed rejected takeoff due engine failure, a Silk Way Airlines Boeing 747-4400 Freighter was abandoned on a Hong Kong Airport taxiway.The aircraft was 15 years old and registered VP-BCV. It was flying 7L-748 between Hong Kong and Baku, Azerbaijan, when one of its Pratt and Whitney PW4056 engine failed during takeoff. The crew quickly brought the aircraft to an abrupt halt after being alerted of the problem. They then taxied off runway 25L onto a last available taxiway. The aircraft was left stranded due to the heat from the sudden braking.Silk Way Wests 747-405F VP-BCV at ground following a failed takeoff due to engine surge on the no.3 engine. This caused 12 tyres to deflate and made the aircraft immobile.Silk Way West Airlines Boeing 747-4H6 (F)VP-BCVVHHH/HKG pic.twitter.com/5sZQDLNTij Haung Yue (@Lrt1001Hk), July 5, 2021The aircraft was evacuated by emergency services. Water was then applied to the landing gear in order to stop a fire starting. During the incident, there were no injuries or deaths.The turbine section of the Pratt and Whitney engine has been severely damaged in this photo.Rear turbine section on the Silk Way Boeing 747 Freighter (Source : The Aviation Herald).This is the latest in a series on PW4000 errorsThis incident is the latest in a long line of engine failures that plague the Pratt and Whitney PW4000 engine series over the last few years. The world was shocked by the engine failure of a United Airlines Boeing 777 flying flight UA328 in February 2021.Following UA328, aviation safety regulators all over the globe ordered emergency inspections for PW4000 engines. These engines can be found on Boeing 777s, 747s, 767s, MD-11, Airbus A300, A310, and A330 aircraft. The FAA advised airlines that they should stop operating PW-fitted 777s until the inspections were completed. Japan Airlines and ANA followed suit, grounding all aircraft equipped with the engine series.A Longtail Boeing 747 Freighter with PW4056 engines was also involved in another incident that occurred in February 2021. It spit turbine blades above Meerssen village. Local residents reported hearing loud bangs and flames, before metal fragments began to fall on the village.While an investigation will probably focus on any possible connections to the incidents involving PW4000 engine, it does not necessarily mean that other factors external or internal won't be investigated. The root cause of the failure will not be known until the parties involved complete their investigations.Silk Way Airlines was asked to comment. We will update you with more information as soon as it becomes available.Images taken from The Aviation Herald
