During replacement of the crossover beam; the parts delivered from stock as Serviceable had been modified by the Aircraft Maintenance Manual (AMM) Supplement and one of the guide lugs was eliminated. The AMM Item 4-B; allows a blend repair referencing Structural Repair Manual (SRM) 54-30-00. After repair; it indicates the replacement of the beam at the next engine change. The two documents are asking for different resolutions leading to confusing instructions. I believe the beams in stock would be reject[ed] based on these documents.
An Aircraft Maintenance Technician (AMT) reports about confusing instructions in their A319 Aircraft Maintenance Manual (AMM) Supplement and Structural Repair Manual (SRM) that allows modification of the V2500 Engine Crossover Beam; but also requires replacement at next engine change.
