engine performance out of tolerances
Hi, everybody,
Following a client oil company auditor request, a power assurance check was performed on a 365 N. One engine has been found unsatisfactory.
The check has been performed several times and the results crosschecked and counterchecked before pronouncing the engine U/S.
Surprisingly, the technical manager flatly refused to change the engine, on which grounds, we do not know.
Instead it has been decided to limit the max gross weight to 3600 kg so as to comply with the JAR OPS 3 OEI performance level.
My fellows and I could not find anything in the books prohibiting or allowing this.
Some think that as long as the minimum RoCs are obtained it is OK. Others think that an aircraft should not fly with an engine out of tolerances, public transport or not, take off mass limited or not.
Everybody considered changing the tech. manager.
Any advice/comment greatly appreciated. Thanks.
