Analysis

Bfr rchg his destn, the plt adzd apch ctl that his rgt eng was 'blowing some smoke' & losing oil pressure. Vectors were provided for a visual apch, but there were low clouds in the area & vis was restricted due to haze. After reaching the vcnty of the arpt, the plt said it was in sight & he was entering a downwind for rwy 30. Witnesses saw the acft on a left downwind, but said the acft overshot the 1st turn to final apch. Subsequently, while maneuvering to land, the acft crashed aprx 2500' NE of the rwy in a wooded area. Witnesses agreed the acft was slow & in a steep rgt turn with the gear extd bfr it crashed in a steep dscnt & burned. An exam revealed evidence the starter on the rgt eng had backed off; 3 starter bolts had fractured thru the threaded area with signs of fatigue cracking; wear marks on the starter gear & eng gear ring indcd the starter motor had shifted aprx 3/4' rearward. Also, there was evidence the torsional damper was loose on its shaft bfr the acdnt & that both props were operg at low pitch drg initial impact.
