Ongoing reliability problems for Trent 1000 engines will lead to even higher repair and compensation costs for manufacturer Rolls-Royce.
Prior to the introduction of the Trent 1000 TEN last year, Rolls-Royce had released two updates for the engine, and the latest problems affects the newest of those--the Package C version.
Durability issues with the Package C’s compressor have forced Rolls-Royce to lower the inspection interval for 380 of the engines from 2,000 cycles to just 300--a move that is certain to hit airline flight schedules.
“We sincerely regret the disruption this will cause to our customers. Our team of technical experts and service engineers is working around the clock to ensure we return them to full service as soon as possible,” said Rolls-Royce CEO Warrant East.
Air New Zealand is among the airlines disrupted, with nine Boeing 787s powered by the affected Package C engines.
It described the increased maintenance checks as a “challenge at what is a very busy time for travel.”
The youngest Package C engines, those with less that 300 cycles of service, are unaffected by the new directive.
Rolls has acknowledged that more regular inspections will lead to higher costs in 2018, although it will seek to reduce discretionary spending elsewhere in order to maintain its free cash flow target for the year.
In its 2017 annual report, the OEM recorded costs of roughly £170 million ($244 million) to cover repairs and compensation relating to the problems with the Trent 1000 and Trent 900.
It said this would double to around £370 million ($530 million) in 2018 before falling to £270 million ($287 million) in 2019, although those forecasts were prior to the latest Package C announcement.
Other airlines reported to be affected by the inspection regime are All Nippon Airways, British Airways, Norwegian and Virgin Atlantic.
