By the way, I got work report on one AC recently, where MRO replied something like: "ok, your cables are overdue. We ordered new ones. Placed as <Hold item>. Will be replaced on next maintenance."
But CRS was signed... What happened in this case ? Aircraft is flying with LLP overdue and nobody cares ? What CAA would say in case of inspection ?
Cannot be done, the 1500 hr max is what is stated in the manual and in EASA/CAA land you have to comply with the manuals limits, you might be able to apply for a dispensation to fly past it from your CAA, say if spares were unavailable as we did on an engine, but that would be between the maintainance company and your CAA....... but as said other countries may vary...... in CAA land Pre EASA all the other limits such as seatbelts used to be on condition as they were checked in company, which is the sensible route, HOWEVER they still then insisted on the 1500 hr rule for the throttle cable.
I replied earlier but the server was busy so I lost the answer I was doing,
The mixture and Carb heat DO NOT have the 1500 hr limit as they can be inspected internally........
The only thing I can think of on the c152 that can exceed the limits is the engine hoses, they can continue in service provided they are deemed servicable, and replacements are immediately ordered and fitted within a set time period.
Trouble with Cessna is they never update the manuals, the brake hoses 5 year replacement in the book is wrong, there was a service letter in 1985 i think, stating if Teflon hoses were fitted the hose part of the inspection went onto condition............ they were supposed to by the letter be incorporated into the manual shortly, alas 26 years later we are still awaiting it being incorporated!!! In fact check out the aileron balancing.............. it is for the wrong type of ailerons!!!! and is wrong.
