Shattered Rolls-Royce machines ground Boeing 787s
LONDON Rolls-Royce Holdings Plc faulty engine blades are deteriorating faster than expected, resulting in additional Boeing 787 jetliner uplift on the ground during initial repairs.
The discovery involves about 120 Trent-1000 turbines, about 8% of the global fleet, and frustrated efforts to reduce the number of inactive devices following a series of engine problems, said a person familiar with the situation. Less than 40 Dreamliners are preparing for immediate attention.
The air safety inspection services will make a formal request for compensation in the coming weeks, said the person who asked not to be cited as a reference. Rolls-Royce showed the part’s shorter life in December, as Air New Zealand Dreamliners were damaged in the following days by aircraft turbines.
The shortcomings contribute to Rolls-Royce’s engine design issues, which have already led the company to charge fees of £ 1.3 billion ($ 2.18 billion). The engine is also immediately facing its image, as its defects affect the very high-powered Model 787, the most advanced Boeing, and airlines are looking for long-range replacement aircraft.
On September 26, Christopher Luxon, General Manager of Air New Zealand Ltd., told shareholders that the engine problem, although not a security issue, was the “biggest operational challenge.” “That had a big impact on their network and their customers Air New Zealand said the airline would cost up to $ 40 million (New Zealand) or $ 34 million this fiscal year.
In five of the 13 Dreamliners that land at one point, the carrier had to lease three aircraft to compensate for the shortage, he said earlier in a letter to the customers.
A spokesman for the Japanese company ANA Holdings Inc., which has equipped 65 Dreamliner with the Trent 1000 engine, said the airline has not yet heard of the latest development of the wind turbine manufacturer. The airline will replace the affected blades and conclude negotiations with Rolls-Royce on the compensation until March, she said on Friday. The airline canceled more than a thousand flights between July and October.
Design issues have impacted the Trent program for two years, wiping Rolls-Royce’s stake in its rival General Electric Co. Medium pressure turbine blades – already marked as replacement – are not long enough to observe the previously defined maintenance program.
“We are proactively implementing some well-known sustainability issues in our Trent 1000 fleet and have made good progress in overhauling and replacing the affected parts,” said Rolls-Royce of London. The problem concerns a minority of 787 engines for which the blades have not yet been replaced and could cause “additional short-term disruption”.
The European Aviation Safety Agency has not requested comments as the US Federal Aviation Administration co-operates with European regulators and Rolls-Royce in this regard.
“Safety remains our top priority as we continue to replace the medium-pressure turbine blades on the Rolls-Royce Trent 1000 Package C engines,” Boeing said in a statement. “Rolls-Royce has already replaced the rotor blades of most engines, and our team works closely with Rolls-Royce to help customers around the world minimize service disruptions.”
Engine manufacturers such as Rolls-Royce are mastering the addition, even to renting replacement aircraft, when design or production problems delay their shipments or force airlines to use inactive aircraft. Rolls-Royce has reduced some of these costs by offering discounts on maintenance contracts or future engine purchases.
The Dreamliners, who were affected by the latest discoveries, had to be informed during the workshop visits about the repair work. The accelerated schedule for replacement of the blades would therefore not necessarily increase the costs already provided by Rolls-Royce. Nevertheless, Rolls could introduce a new bill to compensate airlines for additional flight disruptions.
The British manufacturer has completed a fence repair operation as a customer of the engine, including British Airways, Virgin Atlantic Airways Ltd. and Norwegian Air Shuttle ASA – had to rent jets this summer because the turbines need repairing.
