Analysis

The plt stated that on takeoff roll as the nose wheel was lifted at aprx 60 knots, the acft veered sharply to the left, ran off the runway and collided with the glide slope building. The left eng and propeller were examined and both components were found to be operating normally and the damage found was consistent with a propeller strike and resultant sudden stoppage. No evidence was found during the examination of the acft structure, flight control systems or right powerplant to suggest a failure or malfunction prior to impact with the glide slope building.
