The crew was engaged in a local training flight at Pueblo-Memorial Airport. Following an approach to runway 27, the crew completed a circuit then a second approach to runway 17. After the airplane made a complete stop, the crew initiated a takeoff from runway 17. During initial climb, at a height of 100-150 feet, the airplane nosed over, stall and crashed near the runway end. The aircraft was destroyed upon impact and all three occupants were killed.
Probable cause (official findings): Stall during initial climb after the crew failed to maintain flying speed. The following contributing factors were reported: - Failed to follow approved procedures, - Misused or failed to use flaps, - Flaps found in fully extended 30° position, - Flap setting for normal takeoff is 10°.
