Air Canada Secures FAA Waiver Despite Engine Issues

Air Canada Secures FAA Waiver Amid Engine Maintenance Challenges
Air Canada has obtained a rare slot waiver from the U.S. Federal Aviation Administration (FAA), enabling the airline to maintain critical takeoff and landing rights at New York’s LaGuardia Airport despite persistent engine maintenance difficulties affecting its Airbus A220-300 fleet.
FAA Grants Exception Due to Engine Delays
The FAA’s waiver, announced on December 9, 2025, covers the period from March 31 to April 30, 2025, during which Air Canada faced challenges meeting LaGuardia’s stringent slot usage requirements. The agency acknowledged ongoing supply chain and servicing delays related to the Pratt & Whitney PW1500G engines, circumstances deemed beyond the airline’s control. Without this exemption, Air Canada risked violating the FAA’s “80% use-it-or-lose-it” rule, which governs the retention of historic slots at congested airports including LaGuardia, JFK, and Washington National (DCA). A notable stipulation of the waiver is that Air Canada is prohibited from transferring the protected slots should it cease operations at LaGuardia.
Operational Impact and Industry Context
Air Canada initially requested relief in March 2025, citing broader operational challenges amid engine reliability issues. During the peak of the 2024–2025 winter season, seven of the airline’s 34 A220-300 aircraft were grounded, disrupting key East Coast routes from Toronto and Montreal. Although some engines were returned to service, approximately 5% of the fleet remained out of operation into early 2025, necessitating schedule reductions and resulting in four unused LaGuardia slots during the affected month. These difficulties were further exacerbated by a concurrent pilot shortage at Jazz Aviation, Air Canada’s regional partner.
This situation reflects wider industry pressures. While the PW1500G engine on the A220 has avoided the powder-metal blade issues that affected the PW1100G on A320neo aircraft, operators worldwide have contended with extended repair times. Cirium data indicated that by early 2025, over 80 A220-300s were grounded globally, although this number has since decreased. As of December 2025, 342 A220-300s remain in service, with 61 still parked.
Regulatory Environment and Competitive Challenges
The FAA’s decision arrives amid intensified regulatory scrutiny concerning engine safety and reliability. The agency recently proposed mandatory replacement of high-pressure compressor blades on V2500 engines, highlighting the critical nature of compliance across the sector. Concurrently, Pratt & Whitney Canada is advancing certification efforts for new engines, including the PT9A-11 turboprop and PW220A turboshaft, aiming to address reliability concerns and bolster market confidence.
Air Canada’s competitors are also confronting operational hurdles. Airbus, for instance, has dealt with software recalls and quality control issues affecting its A320 family, underscoring the competitive pressures airlines face to sustain operational reliability and meet regulatory standards.
Outlook
The FAA waiver ensures Air Canada’s continued access to LaGuardia as the airline manages ongoing engine supply constraints, a challenge anticipated to ease later in 2025 with improvements in the supply chain. This episode highlights the intricate balance between regulatory compliance, operational resilience, and competitive dynamics within the contemporary aviation industry.
