Approach Details
The pilot initiated consecutive localizer/DME approaches to an uncontrolled airport after receiving weather information from the AWOS, which was published out of service and broadcasting in the 'Test' mode. Radar data revealed that during both approaches, the airplane descended below the minimum descent altitude (MDA) for each segment of the approach flown.
During the first approach, approximately 10 DME, the airplane was depicted 1,400 feet below the published MDA for that segment and 260 feet below the lowest MDA for the approach. Approximately 8 miles from the airport, the pilot advised that he was unable to activate the runway lights and received vectors for a second approach.
During the second approach, the airplane impacted trees and terrain on a ridge line approximately 500 feet below the MDA for that segment of the approach.
Weather and Conditions
Weather was reported to be variable ceiling 100 feet and 1/4 mile visibility, with light drizzle and fog. In the remarks section of the approach plate for the LOC/DME approach, it stated: 'Obtain local altimeter on CTAF/AWOS, when not available, procedure not authorized.'
