The International Air Transport Association (IATA) welcomed changes by Pratt & Whitney Canada (P&WC) to contractual terms that had raised competition concerns in the market for used engine parts.

The changes remove restrictions on maintenance shops in P&WC’s network that could have limited independent suppliers’ access to used engine material and related service. The changes are limited to used parts for P&WC’s PT6 and PW100-series turboprop engines. They do not cover Pratt & Whitney’s larger commercial jet engines or address the use of regulator-approved alternative parts and repairs.

The scale of current supply chain challenges, including parts shortages and maintenance capacity deficiencies is significant. An IATA–Oliver Wyman study estimated that supply chain constraints added some $5.7 billion to airlines’ engine leasing and maintenance costs in 2025. Greater competition and more options for parts and repairs are among the measures that can help alleviate these pressures.

The outcome of the European Commission Directorate-General for Competition’s P&WC probe adds to benefits gained earlier this year with the renewal of IATA’s agreement with CFM International on aftermarket practices. The agreement enhances competition across CFM’s commercial engine portfolio with a similar focus of increasing maintenance options by enabling independent maintenance providers to compete and supporting the use of all regulator-approved parts and repair options.
