Denver - Boisé

Weather conditions were moderate snow and freezing temperatures. Following a 27 minute delay between deicing and departure, on takeoff the aircraft was over-rotated by the first officer. Aircraft control was lost, the aircraft stalled and impacted off the right side of the runway. Company procedures called for repeat deicing when in icing conditions if a delay exceeds 20 minutes. Confusion between the tower and the flight crew due to procedural errors resulted in the delayed takeoff clearance. Both pilots were inexperienced in their respective crew positions. The captain had 33 hours experience as a DC-9 captain. The first officer had 36 hours jet experience, all in the DC-9. First officer demonstrated weak scan in training and had pilot performance problems with previous employers. First officer was on reserve, and had not flown for 24 days. The trip was assigned to the first officer for proficiency. Flight was first officer's 2nd trip as DC-9 first officer. Wing vortices from a landing aircraft on a parallel runway were not a factor in the accident.

Lt.

Wishing to recognize the contributions of the Patterson family (owners of NCR) the area of Wright Field east of Huffman Dam (including Wilbur Wright Field, Fairfield Air Depot, and the Huffman Prairie) is renamed Patterson Field on 6 July 1931, in honor of Lt.
