Aviation Accident Summary LAX07LA027

Bisbee, AZ, USA

Aircraft #1

UNREG

Air Creations Tanarg 912

Analysis

The unregistered aircraft collided with a steep mountainside. A pilot, who was flying an ultralight in tandem with the accident aircraft, stated that the accident pilot was providing instruction to the student pilot on the cross-country flight. The accident pilot maintained radio communication with him as they both maneuvered through the valleys that led to their intended destination. Throughout the flight, the radio signal was intermittent due to the contours of the terrain. The ultralight pilot further stated that after egressing the valleys he turned around to scan the surrounding area and could not obtain visual contact of the accident aircraft. He headed back up the valley and saw smoke behind a mountain ridge. He circled over the smoke and observed a small brush fire, but could not discern any aircraft structure. He stated that the winds at the time of the accident were calm and there was no turbulence or mountain wave in the areas they were flying. The inaccessibility of the accident site prohibited the wreckage from being recovered.

Factual Information

On November 01, 2006, about 0930 mountain standard time, an Air Creations Tanarg 912 unregistered aircraft, collided with a steep mountain side near Bisbee, Arizona. The pilot/owner was operating the unregistered aircraft under the provisions of 14 CFR Part 91 as a cross-country instructional flight. The airplane was destroyed. The pilot, who held a sport pilot certificate, and a student pilot sustained fatal injuries. The flight departed from Rodeo, New Mexico, about 0830, with a planned destination of Bisbee. Visual meteorological conditions prevailed, and a flight plan had not been filed. A National Transportation Safety Board investigator interviewed a pilot who was flying an ultralight in tandem with the accident aircraft. He stated that the accident pilot was providing instruction to the student pilot on the cross-country flight to Bisbee. The accident pilot maintained radio communication with him as they both traversed through the valleys that led to their intended destination. Throughout the flight, the radio signal was intermittent due to the contours of the terrain. While en route through the Starvation and Skeleton Valleys, the accident pilot made a radio call that indicated he was at the "4-o'clock" position behind the ultralight. The ultralight pilot further stated that after egressing the valleys, he turned around to scan the surrounding area and could not obtain visual contact with the accident aircraft. He headed back up the valley and saw smoke behind a mountain ridge. He circled over the over the smoke and observed a small brush fire, but could not discern any aircraft structure.
