Analysis

Atr plt departing arpt under VMC experienced failure of the right eng shortly after lift-off. The acft yawed right followed by a steep right roll, contacting power lines with the right wing and subsequently impacted the ground. A post-crash fire destoyed the acft with the exception of both engs and a portion of the right wing panel. The eng failed due to lack of lubrication to the impeller shaft caused by blockage of oil jet due to FOD. Oil line from scavenge sump to scavenge pump inlet had been replaced prior to accident. The acft had experienced maintenance problem (oil leak) aprx 2 weeks prior to accident. Source of FOD is undetermined.
