Analysis

At the completion of a period of instrument training and while returning to the airport of origin the CFI asked the private rated dual student to demonstrate a simulated forced landing to the runway. In an attempt to lose altitude on the final approach the dual student allowed the airspeed to decay during a slipping maneuver and the aircraft stalled. Insufficient altitude remained to allow either the student or the CFI to make a recovery before the aircraft struck small trees and slid through a ditch. The aircraft came to rest short of the runway.
