TRENT 1000 TEN SERVICE MANAGEMENT
Rolls-Royce agrees accelerated inspection regime with EASA
As part of our work to respond to earlier than anticipated High
Pressure Turbine (HPT) blade deterioration identified in a small
population of Trent 1000 TEN engines, Rolls-Royce has been working
closely with regulatory authorities to establish a plan for
inspecting the remaining fleet. This accelerated inspection regime
has now been agreed and will be formally communicated to customers
today. As part of this process, an Airworthiness Directive will be
issued by EASA in addition to a Rolls-Royce Service Bulletin.
Following sampling of a population of Trent 1000 TEN engines
that have experienced a higher frequency of flights at the upper
end of their operating range, a small number of these engines have
needed to have their HPT blades replaced earlier than scheduled.
This new accelerated inspection regime is designed to allow us to
confirm the health of the Trent 1000 TEN fleet over the next few
months.
The Trent 1000 TEN engine has been in service since November
2017, and there are currently more than 180 of this type of engine
in service.
Since the entry into service of the Trent 1000 TEN, Rolls-Royce
has communicated to airlines that the HPT blades in these engines
would have a reduced life. As a result, our engineers have already
been developing, and are currently testing, an enhanced version of
this blade. We expect to start incorporating enhanced blades into
the Trent 1000 TEN fleet in early 2020.
Based on our current understanding of the situation and fleet
management plan, our guidance for in-service cash costs on the
Trent 1000 in 2019 and 2020, as published with our 2018 Full Year
Results on 28 February 2019, remains unchanged.
Chris Cholerton, Rolls-Royce, President - Civil Aerospace, said:
"We sincerely regret the disruption this accelerated inspection
regime will cause and we are doing everything we can to support our
customers.
"These inspections will allow us to confirm the health of the
Trent 1000 TEN fleet and to improve our understanding of the High
Pressure Turbine blade deterioration that we have seen in a small
number of engines.
"This blade deterioration is a known issue but it is occurring
faster than we expected on some engines. We started development of
an enhanced blade last year, which we are now testing. We expect to
start incorporating enhanced blades into the Trent 1000 TEN fleet
in early 2020."
This new inspection regime has no impact on our ongoing
proactive maintenance programmes for the Trent 1000 Package B or
Package C engines.
