P&WC Achieves 200th Engine Type Certification - The PW127XT-L Regional Turboprop

Pratt & Whitney Canada, an RTX (NYSE: RTX) business, announced today that Transport Canada Civil Aviation has type certified the PW127XT-L regional turboprop engine. This marks another significant milestone for the company as its 200th type certification since the introduction of the original and now ubiquitous PT6 engine in 1963.

"Achieving 200 engine type certifications within a 60 year period is truly a singular accomplishment in the world of aviation," said Irene Makris, vice president for customer service at Pratt & Whitney Canada. "This milestone is a testament to the dedication, devotion and technical acumen of generations of Pratt & Whitney Canada employees, as we look forward to many more engine certifications in the decades ahead."

The PW127XT-L will power the ATR 42-600S regional turboprop aircraft capable of short take-off and landing, providing a higher thrust rating to enable the aircraft to take off from runaways as short as 800 meters.

"This certification is a significant milestone for the ATR 42-600S programme, as modifications to the engines are part of the major technical changes we are bringing to the aircraft – in addition to the rudder and avionics – with a huge influence on take-off performance," said Daniel Cuchet, senior vice-president of engineering at ATR. "This great achievement comes as a reward after many months of hard work and constant collaboration between the ATR and Pratt & Whitney Canada teams."

The PW127XT engine series is the new standard in regional turboprop aviation, offering 40% more time on wing, 20% reduction in maintenance costs and a 3% improvement in fuel efficiency. The PW127XT-L joins the previously certified PW127XT-M engines which powers ATR's latest generation of aircraft. Another derivative of the engine, the PW127XT-S, has been selected by Deutsche Aircraft to power the D328eco regional turboprop with planned entry into service in 2026.
