Leadsled(GoldWing?) states with no show of evidence:
A well known national representative organisation approached ALL the then providers of Hangar Keepers policies, and quizzed them about placing limitations on policies re. releasing aircraft that had engines over Manufacturers RECOMMENDED TBO. ie: the insurance underwriter placing a limitation on a policyholder using AD/ENG/4 on behalf of a Registered Operator customer.
Then demands of Your Right evidence that Insurers were driving the situation
Prove it, show us an excerpt from a policy.
Having been involved in release to service of on condition piston engines when the AD was first issued, I can vouch for the veracity of Your Right's statement - the Hangar Liability Insurance would not have covered any maintenance that was against OEM recommendation.
Speaking of on condition maintenance, you do realise that this means to remove/repair BEFORE the item breaks down, not after?
So with this in mind, how do you anticipate the stoppage of a Vac pump?
This may be why the OEM recommends a time life.
I am mystified as to why engines in Australia are apparently so mush less reliable,
No need to be mystified Leadsled, As the Robinson Heli Instructer said, " to arrive at true hours multiply the MR hours by a factor of 1. something, except in Australia where use a factor of 3!"
Clinton. After some thought I can see your side of the argument reference CASA Schedule 5: CAR 41 (1) states
The holder of the certificate of registration for a class B aircraft must ensure that all maintenance required to be carried out on the aircraft (including any aircraft components from time to time included in or fitted to the aircraft) by the aircraft’s maintenance schedule is carried out when required by that schedule.
CAR 42B states
(1) Subject to subregulation (2), if:
(a) the holder of the certificate of registration for a class B aircraft that is an aeroplane has elected to use the CASA
maintenance schedule for the aircraft’s maintenance; and (b) the election is in force; the aircraft’s maintenance schedule is the CASA maintenance schedule.
Ergo that is the Maintenance program, PLUS what ever else is nominated on the LBS for that aircraft.
