Philippine Airlines (PAL), a longtime General Electric customer, will switch to Pratt & Whitney (P&W) and Rolls-Royce (R-R) engines for its recently ordered Airbus fleets.

All of PAL’s existing widebodies utilize engines developed by GE and the airline’s current narrowbody fleet is powered by CFM, a joint venture of GE and France’s Snecma.

But industry sources tell AviationWeek PAL has chosen P&W’s International Aero Engine (IAE) V2500s to power the 34 A321s just ordered from Airbus.

These sources also say the airline has opted for P&W’s Geared Turbofan (GTF) for the 10 A321NEOs also included in the new order and R-R Trent 700s for 10 A330s-300s.

First deliveries of PAL’s new A330 are scheduled for the second half of 2013.

It is unclear why PAL decided to switch, although sources say P&W has been aggressively marketing the IAE V2500 and GTF.

In February, India’s GoAir chose the GTF engine to power A320NEOs on order, even though its current-model A320s are CFM-powered.

PAL’s spokesman was unavailable and both engine makers would not comment on the engine choices, which have not been officially announced.

Philippine conglomerate San Miguel bought 49% of PAL Holdings in April from Lucio Tan. As part of the deal, San Miguel chief Ramon Ang became president of the airline.

PAL’s largest local competitor, Cebu Pacific Air, also operates A320-family aircraft, all powered by CFM. A330s ordered by Cebu Pacific will be powered by R-R, according to the Aviation Week Intelligence Network fleet database.
