Manhour estimation
Manhour estimation
(OP)
As usual, everyone know that the aircraft maintenance work is calculated by manhours. Does anyone know that is any guideline or reference for a maintenance manhour estimation?Some of the mechanic told me that they're IMAGE by their own experience. Hm....it seem a little bit confused. Any comment?





RE: Manhour estimation
Often OEMs will estimate the number of manhours required to perform various maintenance tasks on their products. They do "time and motion" studies to determine these values for the "average" person (mechanic) with the correct tools and workshop support. In countries (or towns) where the infrastructure is lacking, these OEM estimates may be over optimistic. It is usually best to perform your own estimates of maintenance operations. Eventually experience will hone your ability to perform such estimates.

Even if there were some sort of Dodge book available, you should keep track so that you can tell if your actual hours agrees with the standard. If it doesn't you can at least try to discover why.

RE: Manhour estimation
In my experience in a 20 a/c fleet and 18 helicopters you can estimate your labortime through 2 different ways:
1.- By crittical dues (your most esperienced mechanic time)
2.- By influence dues (nothing happens if you put some task before or after any)
After you state one of this methods,use a 8 hour day but asumme quarter for it. It means you have periods of 2 labor hour that includes (paperwork, shop repair, storage travel) It´ll be more easy calculate the time needed for a task and how many persons you want to perform the task.
