Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative

Numerous witnesses, some as far away as 25 miles from the accident site, observed a low-flying airplane matching the description of the accident airplane. It was seen to drop down to near the surface of a reservoir, continue for several miles, then pull up and strike four 1/2-inch diameter aluminum high tension power lines that spanned the width of the reservoir. Three lines carried 26,000 volts and the ground (static) line carried 12,000 volts. The distance between the supporting structures was 1,245 feet. The low point of the drooping cables was about 250 feet above the water's surface. The cables were unmarked, and there are no regulations requiring that they be marked. The airplane was flying towards a setting sun when the collision occurred. Both pilots were commercial certificated, instrument rated, and flight instructors. The airplane was equipped with dual flight controls; therefore, which pilot was serving as pilot-in-command during the flight is not known. The medical examiner found a piece of paper clutched in the first (left seat) pilot's fist. It was later identified as being a portion of the Denver Sectional Chart, and depicted an area just north of the accident site. According to the pathologist, the injuries exhibited by the second (right seat) pilot were consistent with (and the injuries exhibited by the first pilot were not consistent with) being at the controls of the airplane. Toxicological screening revealed tetrahydrocannabinol carboxylic acid (marijuana) in the second pilot's blood [0.0096 (ug/ml, ug/g)] and urine [0.0768 (ug/ml, ug/g)]. The first pilot tested negative for drugs and alcohol.

Probable cause

intentional buzzing by both pilots and their failure to maintain clearance with transmission wires. A contributing factor was the sun glare.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
