The A220s have P&W gear fan engines and some have big problems. Spirit and others that have these engines also have problems and Spirit will have up to 40 planes grounded by December. As I understand the issues some engines have parts that were made from a defective powered metal recepie that require parts to be replaced and there are also issues with some engines that have bad bearings. The big problem is the MROs are backlogged and an engine may take upwards of a year from the time the engine is removed before it is returned. I guess the egines on the Egypt Air A220s are not in the batch that are effected so Breeze has leased those planes so they will have access to enough engines they wil not have to ground planes for long periods of time. The Egypt Air planes will stay in Egypt while the engenes go to Breeze.
