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

Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Initial climb
Defining eventThe 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
Loss of control in flight
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The commercial pilot had performed numerous local sightseeing helicopter flights the day of the accident. During the accident flight lift off from the field with power lines and farm equipment nearby, the pilot increased the throttle to the maximum engine and rotor rpm and began a climbing left turn toward power lines, during which he noticed the rotor rpm slowing. He slightly decreased collective pitch and further increased the throttle, but the rotor rpm did not increase. The pilot then increased collective pitch even farther as the helicopter cleared the power lines, which exacerbated the low rotor rpm state and was contrary to guidance published in the helicopter's pilot's operating handbook. The pilot's power management allowed the rotor rpm to decay below a point at which sustained flight was possible. Subsequently, the helicopter descended and impacted an open field hard, which resulted in substantial damage to the tailboom and tail rotor. The pilot did not report any preimpact mechanical malfunctions or failures with the helicopter, which was confirmed by a postaccident examination and test run of the helicopter's engine. The pilot's mismanagement of collective pitch control led to the helicopter entering a low rotor rpm state and its subsequent inability to maintain flight.

Probable cause

The pilot's mismanagement of collective pitch control during takeoff from an area with numerous obstacles, which resulted in the helicopter entering a low rotor rpm state and a forced hard landing.

  • 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: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
