An Engine Mechanic reports receiving another GE CF34-3B engine from a contracted Quick Engine Change (QEC) build Repair Vendor with a Serviceable FAA PMI Tag; even though the Fuel Control Unit (FCU) was mis-rigged and the Fuel Supply feed line at the engine fuel pump connection had a yellow plastic plug in the end fitting.

Narrative

A [General Electric CF34-3B] engine was delivered from Quick Engine Change (QEC) Vendor X. Engine was QEC'd with a Serviceable [FAA] PMI Tag and an additional Serviceable remarks form with 'typical' items listed. After engine installation and prior to 'wet' motoring;the rigging of Fuel Control Unit (FCU) was checked; as required by installation job card. FCU was found to be at 20-degrees on rig protractor at idle setting. Idle is to be at 16-degrees. FCU rigging had to be accomplished. Additionally when 'Wet' motoring process was accomplished; no Fuel Flow was indicated and no noticeable fuel out of engine; other than initial visual evidence; which was determined to be the residual preservation oil. Upon further investigation it was found that the Main Fuel Supply feed line at the fuel pump connection point; the line had a yellow plastic plug in the end fitting; preventing fuel from entering the Fuel pump. Suggestion to avoid re-occurrence will be the same as all other reports filed; for this [Contract] Vendor to have better Quality Control over the work process that is used and better oversight to assure the product is indeed 'Serviceable'.
