Rolls-Royce jet engine which exploded on Qantas A380 superjumbo flight failed due to a 'poorly built oil pipe' Rolls-Royce engine explosion forced an emergency landing in 2010 Superjumbo was forced to turn back with smoke trailing from its engine Rolls-Royce admits it 'fell short' on safety standards A mid-flight engine explosion on a Qantas superjumbo jet in 2010 was triggered by a poorly-built oil pipe, an investigation has revealed. A final report into the forced emergency landing on Thursday prompted Rolls-Royce to admit that it 'fell short' of safety standard. The mid-air failure resulted in Qantas grounding its entire fleet of A380 planes. Rolls-Royce later agreed to pay £58million in compensation to the Australian airline. Damage: Emergency crews in Singapore attending to the superjumbo in 2010 when it was forced into an emergency landing The engine exploded shortly after take-off from Singapore on November 4 2010, becoming the most significant safety concern an A380 had faced since starting passenger flights in 2007. Debris dramatically started raining down onto Indonesia's Batam Island as the plane was forced to turn back. The Australian Transport Safety Bureau's report confirmed the agency's earlier findings that an oil leak from a pipe inside one of the plane's massive Trent 900 engines sparked a fire. It concluded that the walls of several pipes were too thin and did not conform to design specifications. Blowout: The damaged Rolls-Royce engine caused an explosion because of a crack in an oil feed pipe Evacuation: 459 people had to disembark the superjumbo at Singapore's Changi International Airport while firefighters tended to the engine The error prompted a disastrous domino effect, with the weak wall of the pipe breaking down, then cracking and finally releasing oil into the superheated engine, sparking the fire. The fire caused a disintegration of one of the engine's giant turbine discs, sending pieces of it blasting through the plane's wing. Rolls-Royce said it supported the agency's findings and had improved its manufacturing and design processes. 'This was a serious and rare event which we very much regret,' Colin Smith, director of engineering and technology for Rolls-Royce said in a statement. On this occasion we clearly fell short. Improvements: Rolls-Royce said it supported the agency's findings and had changed its design process The transport agency said Rolls-Royce has since identified all the affected pipes, overhauled its quality management system and implemented a safety feature that should shut an engine down before it can blow apart if the same scenario ever happened again. 'This was an unprecedented event and, as the report confirms, all possible steps have been taken to ensure that it can never happen again,' Qantas said in a statement. No one was hurt in the incident.
