Narrative:
A Swearingen SA226-TC, N158WA, was substantially damaged due to foreign object damage to the airplane's propeller and
fuselage during initial takeoff/climb from Boise Air Terminal, Idaho, USA.
According to Federal Aviation Administration personnel, about the time the airplane was rotating from runway 10L, the pilot experienced a light vibration; he subsequently returned to BOI and landed uneventfully. During a post-landing examination of the airplane, it was revealed that a portion of the outboard section of a left propeller blade, which had fragmented
into 2 pieces, was missing. Additionally, about a 4 inch by 4 inch puncture hole was observed to have gone through the left forward side of the fuselage just aft of the main air stair door; a piece of the propeller blade was found in the cabin. It was further noted during a runway sweep for foreign objects shortly after the occurrence, that a screw driver which had been used during maintenance on the airplane earlier, and the second piece of the propeller blade tip, were both recovered from the departure runway in the same approximate location from where the airplane would have rotated.
