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
Part 91: General Aviation
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

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
Visual flight rules (VFR) flight into instrument meteorological conditions (IMC)
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 pilot called the FAA, Anniston FSS about 15 minutes before departure and requested a weather briefing for a flight from Montgomery to Birmingham. The pilot was told that there was an airmet in effect for instrument flight rules conditions from Birmingham northward and that visual flight rules flight was not recommended. The flight departed Montgomery at about 1855. About 1935, witnesses heard the helicopter flying from south to north at a low altitude, making ' a steady, loud, whining noise.' About 2-3 seconds later they heard a 'thump' crash sound and then heard no more sound from the helicopter. They went outside of their house and observed the fire from the wreckage of N395WM. The witnesses stated that at the time of the accident the weather was dark and slightly foggy. Post-crash examination of the wreckage showed the helicopter had impacted in a near nose down vertical descent, while on a 185-degree heading. All components of the helicopter, which are necessary for flight, were located on or around the main wreckage. A post-crash fire had consumed the fuselage of the helicopter. Examination of the remaining portions of the helicopter structure, flight controls, main and tail rotor systems, and engine showed no evidence of pre-crash failure or malfunction. Damage to the main rotor system and engine drive shaft was consistent with the engine and rotor system operating at the time of the accident.

Probable cause

The pilots continued visual flight rules flight into instrument meteorological conditions resulting in his becoming spatially disoriented and loosing control of the helicopter, which resulted in an uncontrolled descent and impact with the ground.

  • 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. Values present in the bulk record are kept.
