Rolls-Royce further broadens Trent 1000 checks

  •  

Rolls-Royce is extending its inspection regime on Trent 1000 engines to include other models of the powerplant which may be affected by the blade durability issue.

While the analysis and examinations have focused on the Package C version of the Trent 1000, the manufacturer says it has found a "similar" issue with the intermediate pressure compressor on Package B engines.

The manufacturer is taking precautionary preventive measures to redesign specific parts in the Package B version as well as its latest Trent 1000 TEN engine.

Rolls-Royce's Package B version has been in service on Boeing 787s since 2012 and comprises 166 powerplants. The manufacturer states that the durability issue has been identified on a "small number" of high-life engines.

"We have therefore agreed with the relevant regulatory authorities, with concurrence from Boeing, to carry out a one-off inspection of our Trent 1000 Package B fleet," it says.

Rolls-Royce says this measure will "further inform our understanding" of the problems involved. It had originally said, when it broadened the extent of Package C checks in April, that neither the Package B nor the TEN would be affected.

But it now admits it is taking the "precautionary" measure of commencing redesign of specific components in the Package B model as well as the Trent 1000 TEN – which has not shown any durability problems, although the TEN engine fleet is young.

The European Aviation Safety Agency is to issue an airworthiness directive covering the extended Package B inspection regime.

"We anticipate there will be a limited impact on customer operations to enable this programme of one-off inspections to take place," says Rolls-Royce. "Engines will be inspected on-wing using existing techniques."

Civil aerospace president Chris Cholerton insists the company is "committed to eliminating" the durability problem from the Trent 1000 intermediate compressor. The company points out that it has "successfully" run a redesigned compressor for the Package C engine.

Rolls Royce Expands Inspections on 787 Engines, More Disruptions for Airlines

Rolls Royce delivered further bad news on Monday this time to airlines who fly Boeing 787 aircraft with the company’s ‘package B’ Trent 1000 engines.

After announcing in April that the checks currently taking place on ‘package C’ engines would not affect the 166 ‘package B’ units, some in operation since 2012, Rolls Royce have now extended the checks and maintenance to these engines.

Monday’s announcement brings to 549 the total number of engines which must be checked for the unreliable parts, a move which will further anger affected airlines coming into the Northern Summer period.

Virgin Atlantic, British Airways, Norwegian Air and Air New Zealand are among the airlines operating the 787 which have had significant disruption to their schedules since the durability issue with parts in the Trent 1000 engine was discovered last year.

Air New Zealand had only last week resumed service with its first Boeing 787-9, delivered in 2014, after it had been grounded for six months after being involved in an engine shutdown situation in December. The airline has been wet-leasing a Hi Fly Airbus A330 and Airbus A340 to maintain its schedule while the original 787-9 and some of its other 787s have been out of service for maintenance checks.

Last week the kiwi carrier announced it would be dry-leasing two Boeing 777s to cover the continuing Trent issue.  CEO Christopher Luxon told Reuters at IATA’s AGM in Sydney last week: “At any one point in time we are planning to have between zero to two aircraft that will be cycling off to have aircraft inspections and/or maintenance.”

The crisis is causing considerable financial and reputational harm to Rolls Royce and the UK’s Guardian newspaper reported on Monday that workers for the company will be next to feel the pain. The newspaper reports that at an investor day this coming Friday Rolls Royce Chief Executive Warren East is set to announce over 4000 job losses at the company.

Independent analysts are predicting that this figure may be higher, potentially up to 10 percent of the company’s 50,000 workforce. This comes after Rolls Royce pledged significant resources to deal with the issue which affects the durability of the compressor in the engine.

Though Rolls Royce is working to resolve the issue, continued disruption will continue to plague airlines as replacement of the compressor is only one part of solving the problem. Affected aircraft with the engines will be subject to ongoing checks at intervals significantly less than operations will have been planned for. Estimates are that up to fifty 787s are grounded at any one time to fulfil the required maintenance checks.

EASA set to order Trent 1000 turbine cover replacements

Operators of Boeing 787s with Rolls-Royce Trent 1000 powerplants are facing further safety measures, with regulators set to order replacement of cover plates on the high-pressure turbine disc.

The European Aviation Safety Agency, in a proposed directive, says an analysis of material conditions used in the manufacturing of the parts found that the cover plate "may have a safe life below its declared safe cyclic life".

It says that this could potentially lead to premature failure of the component, and possible damage to the engine.

Rolls-Royce has issued a service bulletin detailing instructions to replace the parts.

EASA is proposing to order removal of parts which have exceeded 865 cycles since being installed. It is inviting comments on the proposal until 24 July.

Rolls-Royce is still addressing Trent 1000 reliability issues centred on durability of compressor blades within the powerplant.
