I am currently writing a dissertation for my Masters in Maintenance Engineering.
The topic of the dissertation is Fixed Time Maintenance. I am looking at how maintenance is scheduled on a calendar basis versus a usage basis.
From my research I see that the aircraft industry performs a large proportion of their maintenance on calendar and usage
I am trying to learn the operating conditions or basis for performing the maintenance task on calendar or usage.
I know that some maintenance is performed on hourly limit checks or operating cycle limit check. Maintenance used to be performed by Letters, prior to Boeing going to MSG-3 rev2.
I would greatly appreciate any assistance that can be provided or if someone can point me towards some reference material that might enlighten me.
Thanks a lot.
