Primary finding
Probable cause
The pilot's failure to maintain the minumum descent altitude (mda) while on a non-precision instrument approach. Factors which contributed to the accident were: the flight service station (fss) specialist's failure to provide the published notice to airmen (notam) information to the pilot during the weather briefing, and the controller's failure to remember that the vor-a approach was not authorized.
Investigator assessment
Analysis narrative
During his wx briefing before flight, the plt did not request published NOTAM information which would have advised him that the vor apch to the destination arpt was not authorized. Upon arriving in the vicinity of the destination, the pilot was radar vectored and then cleared for the vor-a approach. In response to the controller's query about receiving the vor, the plt stated 'got it.' the last radar return showed the airplane at 200 ft. The airplane collided with a power line safety cable aprx 115 ft agl. The vor-a approach had been notamed as being not authorized because a flight check showed the approach radial as being rough with scalloping. The minimum descent altitude was 680 ft.
