A Final Check Engine Inspector reports that for the past several years; PW4000 engines have been and are being released for service without the engine power rating and configuration stenciled on the fan case.

Narrative

A PW4000 engine was released for service without the engine power rating and configuration stenciled on the fan case. The engine shop operating procedures require that this information be stenciled on the right side of the fan case. For the past several years all PW4000 engines have left the engine shop without this required information on the fan case. As the final check engine inspector; I have made countless write-ups on engines not having this information. Every time my write-ups are overridden; by both production and inspection management; saying either that the carrier procedure was going to be changed; or that it did not apply to this type of engine. The engine shop procedure is in fact contradictory; in regards to the PW4000 engines. On page #1; it states the information is required for these engines; but they are not listed in the associated figure of carrier procedure. I was asked twice in the last 15 months by the inspection manager to give him a corrected copy of the carrier procedure; so he could make the necessary changes. I did this; but no changes have been made. Per our carrier quality policy; quality alert bulletin and ISO 9000 procedures; the manuals must be followed or changed. If the manual calls for more than we really intend to do; it must be changed before we do less. This has not happened and as a result for years engines have left the engine shop without the required information stenciled on the fan cases.
