Hello to everyone !
As the maintenance organisations hates to replace costly HT's/LLP's I need to be confident when they will blame me for asking to replace, let's say, throttle+mixture control cables.
Cessna 152 AMM says about engine control cables:
Inspect each 100 hours for general conditions and freedom of movement. These controls are not repairable. Replace every 1500 hours or whenever maximum linear movement exceeds 0.050 inch.
So far I was thinking, that these cables shall be replaced each 1500 hours TIS in any case (assuming, that linear movement is always ok). But now I see, that there is no widely used (in 152 AMM also) magical "whichever occurs first" phrase at the end. The same thing about fuel tank inspection: "each 1000 hours, or to coincide with engine overhaul".
So.... can we wait until control cables will be inoperative (linear movement exceeded or just poor condition) and then replace it ? Can we perform fuel tank inspection only at engine overhaul ?
If inspector comes, can I point that "there is no
<whichever occurs first>, so this note gives us an option to do this OR to do this" ? Overdue life limited part is finding 1, right ?
P.S. By the way, is carburetor heat cable also referred to engine c.c. ?
