“airBaltic can confirm that during the first two introduction years of Airbus A220-300 operations the airline had conducted 50 engine replacements due to different reasons, including planned and scheduled replacements.”

The maths

Now, according to airBaltic, the airline’s 14th Airbus A220 was delivered two years after the first aircraft. As the engine replacements occurred within the first two years of A220 operations, the engine replacements would have taken place across 13 Airbus A220 aircraft.

As the Airbus A220 has two engines, a fleet of 13 aircraft would make up a total of 26 engines. As such, if 50 engine replacements were required, every aircraft would have had each of its engines changed around twice in the space of two years.

What is more likely is that some of the older aircraft would have had more engine changes, and some of the newer aircraft would have had fewer engine changes as they hadn’t all been flying for the same period of time. However, to have an average of two changes per engine during the first two years does seem surprising.
