Aug 11, 2023 (newstodate): Recurrent problems with the Pratt & Whitney PW1500G turbofan engines powering the Airbus A220-300 aircraft will still need some 18 months before fully solved, according to airBaltic, the second-largest operator of the aircraft after Delta Air Lines.
   Over the past year, the airline has seen 11 of its now 42 aircraft on the ground pending deliveries of the components needed to replace the malfunctioning turbofan engine lubrication systems leading to an in-flight drop in oil pressure.
   On several occasions, aircraft have been forced to return shortly after take-off due to low oil pressure, forcing P&W to publish recommendations on additional inspections to be carried out in accordance to the manufacturer's specified schedule and guidelines to ensure the continued reliability of flight operations.
   The problems have been exacerbated by the disruption of the global supply chains, leading to overly long and unpredictable delivery times for new lubrication systems to reach operators.
   According to airBaltic, the issue is now expected to haunt the industry until the end of 2024.
