C'mon Leadsled,
". The bulk of the aviation world (airlines) work their aircraft largely "on condition"
That's not entirely the whole story as you know, many airlines have their
Own SOM which usually follows Boeing for instance more of less, and yes have to inspect the health of many components from time to time, even if their not removed from the aircraft,
And there are plenty of components that are life'd also.
(You might term that on condition, with required inspections none the less, you might consider the periodic/100hrly to be the on condition and the IRAN or 4 yearly component change/shop visit).
In other words,
The inference is that components are left if they are working, they are left in use as a result
Of inspections that then allow it to continue in operation.
An example of this may be the allowable time limits for a retract on a Cessna and so on even when the power pack has a major service interval.
(Since it was brought up, if one is going to compare to the airlines, how about we DO adopt some of their maintenance practices, like a major inspection every 3 or 4 years down to the nut and bolt.... Oh hang on a sec, didn't we used to already have something like that!)
The flow of information from maintenance base to engineering, compliance,
Maintenance control is a much shorter route than in GA.
I've seen inspection and change times reduced in response to findings as you would expect.
Most GA operators don't have the avenue of inspecting components in house
To satisfy the major Service Manual requirements, hence why they are sent out.
And that's where the requirements are, remember, you cannot elect to use a maintenance schedule that does not cover the inspection of components that may be necessary from time to time, if you are using a maintenance schedule that does not cover the components fitted to the aircraft, the maintenance schedule is said to be defective and you must notify CASA within 7 days that it is deficient, read that somewhere before?
You can use one of Three maintenance sched's as you know,
But the CAR's explicitly say that forever which one you use, components and required inspections must be covered. Per the manufacturers approved Data.
