Plane and simple: Airlines have been stripping parked aircraft of engine parts for their existing in-service fleet in order to reduce cost. As the demand in traffic increases, eventually these stripped aircraft will have to be entered back into service and they will need parts.

The HEI 1M share repurchase program (on top of the existing repurchasing), is a good sign that we have seen the bottom.

"According to Flight's ACAS database, around 1,400 aircraft were parked at the end of February - 49% more than 12 months earlier. The bulk of these - over 70% - are narrowbodies."
