As for UK sticking to all the manufacturers overhaul periods ,really?.
The 12 year engine overhaul is not adheared too, if used privately,this should also be applied to the gear, lets be sensible.
Common sense went out when easa came in, mainly due to caa gold plating of the rules, and any variations in the application of the rules by CAMOs and MOs are due to lack of understanding and/or a willingness to go out on a limb - for which they wont be thanked in the long run.
we have a procedure for engine tbo extension in the uk, so that issue is already covered, but rumour control has it not for much longer though.
the discussion of whether manufacturers items deemed mandatory by the maintenance program are mandatory or not is a no-brainer, surely - its clear to me if you are obliged to do something you do it, and if you are not then its up to you.
Thus, our obligation to follow the requirement "Overhaul, additional inspections and test periods shall be those recommended by the type certificate holder or supplementary type certificate holders" here, the word "SHALL" does not mean can, might, maybe or any other choice giving you the option. If that wasnt the intent, it needs redrafting. Didnt the FAA have a FAR about this? - ISTR but cant find it anywhere
On-condition is fast becoming an alien concept, which, quite frankly is ridiculous-it takes decision making away from those doing the work and costs the owner more for no appreciable gain in safety. Owners dont like it, but are stuck with it until the next regulation backtrack session.
