Pratt & Whitney Canada Eases Aftermarket Restrictions on PT6 and PW100 Turboprop Engines Following EU Competition Probe

Pratt & Whitney Canada (P&WC) has removed restrictions on maintenance shops in its network that had limited independent suppliers' access to used engine material and related services. The changes follow a probe by the European Commission Directorate-General for Competition and apply exclusively to used parts for P&WC's PT6 and PW100-series turboprop engines. They do not extend to Pratt & Whitney's larger commercial jet engines, nor do they address the use of regulator-approved alternative parts and repairs.

The International Air Transport Association (IATA) welcomed the development but called for broader action. Nick Careen, IATA's Senior Vice President Operations, Safety and Security, said the principles of fair access, competition, and customer choice should apply across the entire engine aftermarket, regardless of engine type. He said greater competition could, in the short term, help ease parts shortages and maintenance capacity constraints that have raised costs and grounded aircraft, and in the long term would bring efficiencies to the sector.

An IATA–Oliver Wyman study estimated that supply chain constraints added approximately $5.7 billion to airlines' engine leasing and maintenance costs in 2025. The P&WC outcome follows a separate agreement reached earlier this year between IATA and CFM International on aftermarket practices, which similarly aims to enhance competition across CFM's commercial engine portfolio by enabling independent maintenance providers to compete and supporting the use of all regulator-approved parts and repair options.

This case shows how a regulatory competition inquiry can pry open an OEM's grip over who gets to touch used engine material, even when the change is narrowly scoped. Engine aftermarket economics have long depended on manufacturers controlling network shops' access to used parts and repair data, which limits how much independent MRO providers can compete on price or turnaround time; when that access loosens, it tends to happen engine line by engine line rather than across a manufacturer's whole portfolio.

IATA's push for the same principles to cover commercial jet engines, and the earlier CFM agreement, point to a broader campaign playing out one OEM and one engine family at a time. Whether P&WC's larger commercial jet engines, or other manufacturers' comparable restrictions, follow the same path will depend on further regulatory or commercial pressure rather than on this decision alone. The next marker to watch is whether IATA secures a similar commitment covering Pratt & Whitney's commercial jet engines, or whether the $5.7 billion cost estimate becomes a reference point in future negotiations with other OEMs.
