Analysis

During a descent to the 5,042 ft elevation arpt the acft impacted the trees and mountainous terrain at the 7,000 ft level. According to the pilot, with the hooded student pilot at the controls, the flight began it's descent from 10,500 ft 30 miles from the arpt. During the descent the local altimeter setting was dialed in and the CFI realized the acft was too low. A climb was called for and the trees were seen just prior to impact. The CFI stated that they had been working on VOR intercepts during the descent.
