For instance: AWB for fire extinguishers, is this mandatory and if so why isn't it in CAO 105.5?
Why can't I do a rotor track and balance on my licence but can do it under a CofA ?
Now onto oncondition engines: Recent experience with an IO540 C engine, satisfies Lycoming SB requirements for hard time of 2400 hours, extended from 2000 hours nominal.
Last inspection all cylinder compressions greater than 73/80 psid, boroscope inspection shows good barrels with very minor ring ridge, nil debris in oil filter for the last 1000 hours I've been looking at it.
Engine meets power requirements for flight and aircraft is released to service in aerial work category. Engine is now at 2550 hours since OH.
I had no problems releasing it for 100 hours, what are your thoughts?
Do ypu mean 100.5 ? Because that is only half that is required.
As for your engine. Thats not on condition but extension under the sb. I suspect its a lyco.?
Under the sb if you meet the requirements of the sb, like min hours per month etc you can extend the o/h period.
On conditionfor the others is over a 12 year or over hours in private / aireail work . There is no on condition for charter.
If your work pack is from a approved maintenance controler then you are cover if any thing is left out of the work pack. A maintenance controller can issue for both class A and B work inspections
. A maintenance controller must be used in class A only.
