Another airline to take a hit due to Pratt and Whitney engine issues is Turkish Airlines with the grounding of four Airbus A321neo aircraft in Istanbul due to Pratt & Whitney PW1100G-JM engines issues. The four aircraft have been grounded since March 2023.
The grounding of the four jets has caused some disruption to the airline’s operations, but Turkish Airlines has said that it is working to minimize the impact on passengers.
The problems with the PW1100G-JM engines are due to a number of factors, including oil leaks, compressor stalls, and high-pressure turbine blade failures. Pratt & Whitney has been working to address these problems, but they have not yet been resolved
The engine problems with the A321neo are a continuing issue, and have resulted in similar groundings and operational disruptions with other operators globally like Indigo, Go Air, Air New Zealand and others.
The engine has been plagued by issues since it was introduced in 2016 like high oil consumption, engine failures, and delays in engine deliveries.
In 2018, the European Aviation Safety Agency (EASA) issued an airworthiness directive (AD) requiring airlines to inspect the engines for oil leaks and other problems.
The AD also limited the number of hours that the engines could be operated before they needed to be inspected.
