Preflight and NOTAM Information
During the weather briefing conducted before the flight, the pilot did not request published NOTAM information. This information would have advised the pilot that the VOR approach to the destination airport was not authorized at the time of the flight.
Radar Vectoring and Approach Clearance
Upon arriving in the vicinity of the destination airport, the pilot was radar vectored by air traffic control and then cleared to conduct the VOR-A approach. The controller asked the pilot whether he was receiving the VOR signal, to which the pilot replied, "Got it."
Collision with Power Line Cable
The last radar return from the aircraft showed it at an altitude of 200 feet. The aircraft subsequently collided with a power line safety cable at an altitude of approximately 115 feet above ground level (AGL). The minimum descent altitude for the VOR-A approach was 680 feet AGL.
Status of the VOR-A Approach
The VOR-A approach had been published as not authorized via a NOTAM. The reason for this status was that a flight check had determined the approach radial to be rough with scalloping, rendering the approach unreliable.
