Narrative:

Nose landing gear (nlg) aft door. Aft hinge repair bushings part number (P/north) XXX-1. These flanged bushings are part of a repair for worn hinges (oversized). The problem is this P/north XXX-1; I believe; are not manufactured (mfg'd) correctly; compared to the others we have had in the past. These bushings are approximately half the length of the others. If you look at page 4 of 4; of the airbus supplement to the aircraft maintenance manual (amm) 52-003; it does not show what the length should be for the flanged bushing; but the non-flanged bushing shows a typical length of .155' to .160' of an inch. In my opinion the flanged bushing should be .155' to .160' of an inch; plus the flanged dimension of .078' to .080' of an inch. Most of the bushings are found in [stores] kit XXX [parts bin] for the maintenance base; since this is a common repair at every [C-check] visit.
