Maintenance has come a long way since the early days when maintenance programs owed more to the perception of the maintenance needs, as opposed to the analyzed and justified needs. In addition the role of the regulator was also minimal, and in part developed as a result of events, incidents and accidents. 

During the end of the first half of the 20th century regulations began to strengthen and the aircraft manufacturer was seen as the appropriate source of the maintenance program development. The early attempts at effective maintenance (in the 1960’s) saw time limits developed which resulted in aircraft being progressively dismantled, in what became know as Hard Time primary maintenance.

All hard time components were then routed through an overhaul process and after an appropriate restoration process were considered as zero timed. (Means they were considered as zero life and good to go again) - Following investigations into the effectiveness of the Aircraft Maintenance Process, by both the FAA and several airlines, a number of determinations were made.
