Evergreen Aviation Technologies (EGAT) and GE Aviation will shift all GEnx and CF6 engine shop operations and management to GE Evergreen Engine Services (GEEVES) by 2020, a joint venture established by the two companies in 2014, under an EGAT corporate restructuring.
EGAT’s specialty is the GEnx-1B and GEnx-2B, as well as the CF6-80C2 and CF6-80E.
GEEVES was primarily established to focus on aftermarket services for the GEnx engine family, leveraging EGAT’s center of excellence status with engine repairs and overhauls on GE’s CF6 engine, explains Kin Chong, EGAT’s executive vice president, business coordination division.
According to GE, its contribution to the joint venture, in which it will hold the majority stake, will be investment, tooling and training. EGAT will contribute its existing overhaul facility, infrastructure, tooling and employees. GEnx and CF6 work is transitioning to GEEVES on a phased basis, with completion targeted by Dec. 31, 2019.
EGAT has been an aftermarket support facility for GE engines since 1999, as an independent MRO in partnership with the OEM, starting with the CF6 engine family. From its strategic location at Taoyuan, Taiwan’s primary air logistics gateway, EGAT’s portfolio of engine maintenance has expanded to include GE’s complete product line of widebody aircraft powerplants.
GE facilitated the development of EGAT’s engine shop, specifically through incorporating the OEM’s shop systems and processes that were modified and integrated into EGAT’s engine shop operations. The OEM maintained a minority stake in EGAT as an integrated airframe and engine maintenance MRO until 2013.
GE Aviation holds the majority stake in the GEEVES joint venture.
“Prior to 2020, EGAT will operate as an OEM-affiliated independent engine shop. Post-2020, EGAT’s engine shop will have been transferred over to GEEVES,” says Kin Chong, EGAT’s executive vice president, business coordination division. “The current relationship between GE Aviation and EGAT is ‘business venture partners through GEEVES.’”
Chong explains that the main focus of the EGAT engine shop is the GEnx-1B, GEnx-2B, CF6-80C2 and CF6-80E1, as well as the GE90. Other GE engines serviced by EGAT include the CT7 turboprop and /T700 turboshaft.
EGAT is projected to perform maintenance on 290 engines in 2018, and, according to Chong is running at full capacity.
Shop capabilities include performance restoration and overhaul on GEnx-1B, GEnx-2B, CF6-80C2 and CF6-80E1 engine types, with piece-part component repair capability supported by in-house EGAT resources as well as the GE repair network. EGAT also offers on-wing-support, and top-case and lighter engine repair capability on the GE90, as well as performance restoration on the CT7/T700.
“EGAT provides AOG as well as on-wing-support services to airline partners operating in the region, such as UPS Airlines and Asiana,” says Chong.
Examples of airline customers on maintenance-by-the hour programs include Delta Airlines, Vietnam Airlines, Garuda, and EGAT’s parent company, EVA Air. Other airline partners, under time-and-material plans, include, among others, Asiana Airlines, China Eastern, Shanghai Cargo, Phillipine Airlines and Hainan Airlines, as well Skymark, TUI and TUI Nordic.
Over the years, EGAT has encouraged its customers to switch from non-OEM parts to OEM materials in order to optimize engine life cycle performance.
“Our airline partners have been experiencing first-hand the benefits of using OEM parts throughout the engines’ life cycles,” Chong reports. “For example, for one customer, the average on-wing time for the engine type in its fleet improved by 20% with the material switch to GE’s OEM material kits, which were jointly developed by GE and EGAT. This has resulted in a reduction in shop visits from a planned average of 13 engine inductions per year to an average of 10,” he says. EGAT continues to work with GE to incorporate PIP (Performance Improvement Program) improvements as operational engine enhancements for improved reliability.
