Pratt & Whitney Engines Quietly Propel G500 Toward Aircraft Certification


As the Gulfstream G500 advances steadily toward its anticipated 2018 entry into service, some of that success stems from the test achievements of its Pratt & Whitney Canada engines.

The G500 is outfitted with PW814GA engines, part of the next-generation PurePower PW800 series that is designed to provide best-in-class performance, dependability and fuel-efficiency.

Although Pratt & Whitney Canada has built more than 52,000 engines across its various models, testing for the PW814GA has been long and rigorous, totaling more than 7,186 total hours since the first engine ran in April 2012. The PW814GA received type certification from Transport Canada, the nation’s transportation regulatory agency, in February 2015.

Aircraft engines receive two levels of certification. The engine manufacturer receives a type certificate, but additional testing and certification comes as the entire aircraft moves toward entry into service.

Pratt & Whitney conducted a battery of tests that included water and hailstone ingestion and 400 hours of endurance testing, which push engines to severe operating conditions to validate durability in a variety of maximum performance settings.
