Rolls Accelerates Trent Blade Swaps
Rolls-Royce is fast-tracking the removal of certain older Trent 1000 intermediate-pressure turbine (IPT) blades and modifying its blade-life calculation methods in the aftermath of a Norwegian Air Boeing 787 engine failure near Rome linked to blades that cracked before established life limits.
The Aug. 10 incident occurred just after Norwegian 787-8 LN-LND departed Rome-Fiumicino Airport (FCO) for Los Angeles. The left-side engine failure sent blade fragments into the streets of the Fiumicino suburb. The flight crew shut the engine down and safely returned to FCO.
An update from Italy’s ANSV accident investigation body issued Sept. 4 said that two adjacent IPT blades failed inside the Trent 1000-G/01A—a Package version. The forward blade suffered a “progressive failure,” while the trailing blade suffered an “overload failure,” ANSV said.
The progressive failure is similar to 10 previous Trent 1000 incidents linked to sulphidation-related fatigue caused by pollutants interacting with high engine temperatures. The issue affects both Package B and Package C variants.
Europe’s In-Service Engine Fleet, 2028
The number of in-service engines in Europe is expected to reach over 20,100 by 2028. New-generation engines will gain a strong foothold. The venerable CFM56 will just slightly lead the up-and-coming Leap engine as the two dominate the commercial engine market in Europe’s future.
Heston MRO Grows Australasian Footprint
Heston MRO continues to grow its footprint in the Australasian region with two new developments to further its Japanese business. The MRO’s Perth line station has received Japan Civil Aviation Bureau (JCAB) approval and is now providing full technical handling for All Nippon Airways (ANA).
The airline announced the launch of daily Boeing 787 flights to Perth in late 2018. Heston MRO says its Perth line station is only the second technical handling agent for the worldwide carrier to be awarded full certification privileges from the commencement of ANA services at a new station. ANA’s first flight to Perth landed on Sept. 1, and the MRO provider began maintenance work immediately—with the flight’s technical handling coincidentally being performed by a former ANA engineer who now works for Heston MRO.
According to Adrian Beirne, Heston MRO’s CEO, the Perth team will offer ANA full technical handling including transit maintenance, defect rectification and AOG support. The line station handles approximately 16 daily flights that include the 787 along with 777s, Airbus A320s, A330s and A350s.
Heston MRO has been providing maintenance services to ANA since 2015 at its Sydney line station, which already holds JCAB approval.
In April, Heston MRO shared intentions to achieve certification for on-wing technical capabilities this year so it could offer the service to airlines, leasing companies and OEMs in the region. Beirne says the engine on-wing services business is progressing, and interest from engine OEMs has been very positive. Heston MRO has submitted its application for extension to its existing Australian CASA Part 145 capabilities and its initial application for EASA Part 145, which includes engine on-wing services capability.
