Approximately a third 30% of jets equipped with Pratt & Whitney’s PW1000G turbofans are grounded around the world. This situation stems from a recall issued by Pratt & Whitney for inspections and replacements of engine parts due to defects in metallic components, caused by the use of contaminated powdered metal during manufacturing.
As of April 1, 2024, data reveals that 637 jets with PW1000G GTF engines are parked, making up 32% of the total fleet equipped with these engines. This includes a substantial number of Airbus A320neos and A321neos, along with A220s and Embraer E-Jets E2s. Despite the lack of specific reasons for each aircraft’s storage, many are sidelined due to technical issues, with a significant portion likely affected by the engine’s manufacturing defects.
Pratt & Whitney, while opting not to comment on the current number of out-of-service aircraft, has previously noted an expected average of 350 A320neo-family jets to be grounded between 2024 and 2026 due to this issue. This scenario underscores the stark contrast to fleets powered by competing engines, such as the CFM International Leap-1A turbofan, which sees only a fraction of its fleet stored.
Airlines Adapt to Unprecedented Challenges
The ramifications of the engine defects are profound, with airlines having to adjust expansion plans, overhaul operations, and seek additional aircraft in a tight market. The financial strain is palpable, as airlines negotiate with Pratt & Whitney for compensation to offset the impact of grounded jets.
Swiss International Air Lines, for instance, anticipates having 10-12 of its GTF-powered aircraft grounded at any given time throughout the year. In response, Swiss is leveraging wet leases to mitigate capacity losses, despite the logistical complexities of sourcing aircraft in an already constrained market.
The ongoing issue has prompted a slight decrease in the number of parked PW1000G GTF-powered jets, hinting at a potential stabilization. This slight improvement follows a steady increase in grounded aircraft since the wider implications of the manufacturing defect were disclosed in July last year.
A Unified Front in Aviation
This challenge is not isolated to engine issues alone. Airlines also face delays in receiving new jets, compounded by labor shortages and supply chain disruptions. However, the GTF engine dilemma remains a focal point of airline frustrations, necessitating a collective response from the aviation community to address and overcome these hurdles.
The industry’s resilience is tested as airlines, engine manufacturers, and regulatory bodies collaborate to ensure the safety and reliability of the global fleet. The path to resolution involves comprehensive inspections, timely replacements, and a commitment to maintaining the highest standards of aircraft performance and passenger safety.
