Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that a normal runup was completed before takeoff. During the takeoff roll, the aircraft accele- rated through 75 knots when a loud bang was heard from the left side. The takeoff was aborted and a rollout accomplished. Examination of the left engine revealed that one of three left propeller counterweights were missing. Each counterweight is secured by a single bolt and locking nut. Examination of the bolt tub revealed evidence of pre-load stress. A service bulletin was issued on March 03 1982, stating that to reduce pre-load stress on the counterweight bolt, the torque specification has been reduced from 105-100 foot pounds to 65-60 torque pounds.
