Analysis

The civil air patrol (cap) organized & provided instructors to teach cap mission plts techniques of 'high altitude' search flying during a 2-DAY course. The curriculum included making a landing approach to a 6080 ft elevation airstrip. The approach was to be terminated with a go-around for which successful execution required promptly turning the acft away from the rising terrain located beyond the departure end of the rwy. The trainee-pilot flew the approach but allowed the airspeed to slow below the best angle of climb. While the gear & flaps were being raised the plt also failed to promptly turn the acft away from the rising terrain. Because of the 8500 ft density altitude, the acft's climb performance was degraded, & the acft collided with the rising terrain. The CFI failed to adequately monitor his student's performance, & he failed to follow established cap procedures which required him to issue mission abort instructions in a timely manner.
