Etihad Airways’ technical maintenance department recently set a world record for replacing a GE90 engine on one of its Boeing 777 passenger aircraft in less than seven hours.
Normally, the time taken to replace an aircraft engine is usually between 20 and 25 hours, which can cause significant operational disruption to flight schedules and reduce profitability. The record was achieved by a team of 12 mechanics and engineers, who have been looking at ways to enhance efficiency and minimise aircraft down times due to scheduled engine replacements.
Jeff Wilkinson, Etihad Airways’ senior vice president, technical, said: “We are highly focussed on maximising efficiencies. This is done by streamlining and enhancing processes to ensure our aircraft maintenance turnaround times are minimised.”
All Etihad Airways Boeing 777 aircraft undergo a maintenance program that includes ‘A’ checks at three-month intervals. The GE90 engine is a fuel-efficient and environment friendly engines which offers a five to six percent reduction in fuel burn.
