Pratt & Whitney’s Singapore engine shop, Eagle Services Asia, has begun overhauling its first PW1000G-series geared turbofan.

The operation – jointly owned by P&W and the engineering arm of Singapore Airlines – has invested nearly $85 million to be able to service GTF powerplants and the Engine Alliance GP7200, the US engine maker says.

Previously, the MRO facility concentrated on support of PW4000 and General Electric GE90 engines.

Part of the investment plan was to establish a ground-based flow-line under which PW1000G-series engines will move between different stations – for disassembly, repairs and re-assembly – rather than stay in a single bay for a shop visit. The flow-line will be gradually activated in 2019 and have capacity to service six engines at a time.

P&W notes that efficiencies gained through the investment will also benefit customers with other engine types.

The first GTF to enter the shop is a PW1100G – an option on the Airbus A320neo.

Versions of PW1000G are additionally employed on the A220, Embraer E-Jet E2-family, and in-development Irkut MC-21 and Mitsubishi MRJ. The GP7200 is an option on the A380.

Eagle Services Asia managing director Ying-Kiong Yip states that the investment is part of a "period of expansion and growth" and has enabled technical staff "to handle advanced materials and automation".
