P&WC still working on nacelle for Gulfstream G500

Pratt & Whitney Canada is continuing to work on certificating the nacelle for the Gulfstream G500 large cabin business jet, but certification and entry into service are expected later this summer, United Technologies chief executive Greg Hayes says.

Gulfstream originally planned to certificate the G500 in 2018 when launching the programme more than three years ago, but then accelerated that schedule to the second half of 2017.

As the accelerated deadline came and went, Gulfstream explained that one supplier did not anticipate some of documentation requirements needed by the European Aviation Safety Agency. Gulfstream reset the entry-into-service for the G500 back to the original schedule of 2018.

UTC subsidiary Pratt & Whitney Canada (PWC) supplies the integrated propulsion system for the G500 to Gulfstream. The system includes PW800 engine and the nacelle.

“The engine is certified,” Hayes told analysts during a first quarter earnings call on 24 April. “”We’re still doing some work on the nacelle.”

Hayes adds that entry into service remains on track for later this summer. “I don’t think there’s any drama there,” he says.

In 2014, P&WC announced selecting Oklahoma-based Nordam to supply the inlet, nacelle and thrust reverser for the PW800. Earlier this year, Austria-based FACC Aerospace announced they had been selected by P&WC to supply hybrid metallic-composite fan cases for the engine.
