New jet engines are still causing problems, driving a historic boom in the aftermarket for parts and MRO services

Reliability issues with new-generation engines and delays in jet deliveries are forcing airlines to extend the life of older aircraft. That is turning the market for parts, MRO work and leasing into a genuine cash machine.

Why this company: Certified PMA replacement components and repair services are what saves many airlines from being bankrupted by the cost of maintaining an ageing fleet. The company earns well off the imperative that forces carriers to keep flying older jets.

Where these numbers come from

The reference price is recorded on the thesis publication date and never changed afterwards. The current price is refreshed several times a day. Returns are in the listing currency and exclude dividends, so for dividend payers the real total return was somewhat higher.

This is not a recommendation to buy or sell. A company enters a basket as a beneficiary of the mechanism described in the thesis, and the full argument is on each thesis page.
