Pratt & Whitney PW812GA engine certified for G400 business jet


Pratt & Whitney’s PW812GA engine has been certified by Transport Canada for use on the Gulfstream G400 business jet.

Maria Della Posta, president of Pratt & Whitney (P&W) Canada said, “We worked closely with Transport Canada to create an efficient and thorough certification process that successfully led us to this point.

“When it enters into service the G400 will be the third Gulfstream aircraft to rely on our PW800 engine family. We are gratified by the steady progress the PW800 engine family has achieved based on its ability to deliver a new level of performance and efficiency to the large cabin business aircraft class.”

The PW814GA-powered G500 entered into service in September 2018 followed by the PW815GA-powered G600 in August 2019.

According to P&W the PW800 engine offers double-digit improvements in fuel burn, emissions, maintenance intervals, and is quieter compared to previous engines. The PW800 shares a common core with the P&W GTF (Geared Turbo Fan) commercial jet engine, which has flown more than 2.2 million hours since its launch in 2016.

The PW812GA has been through more than 3,400 hours of engine testing, including 260 hours of flight testing. Across the PW800 family, more than 175,000 hours of testing and field experience have been achieved. The PW814GA and PW815GA engines have flown more than 144,000 hours since entering into service.

“When we designed the PW800 engine, we did so with all of the engine’s key stakeholders in mind – passengers, pilots and maintenance crews,” said Edward Hoskin, vice-president, Engineering at P&W Canada. “The PW800 has numerous inherent advantages and functionalities to ensure best-in-class availability and to create an exceptional engine response. It also sets the industry standard for maintenance, requiring 40% less scheduled maintenance and 20% fewer inspections than other engines in its class.”
