1984-01-05: Piper AEROSTAR 601P (N234AD) — Salt Lake City, UT

Salt Lake City, UT, US

On January 5, 1984, a Piper AEROSTAR 601P (registration N234AD) was involved in an aviation accident near Salt Lake City, UT. Investigators recorded the probable cause as: The pilot's distraction from a cabin door left ajar, which contributed to the aircraft entering a stall profile in instrument meteorological conditions. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Aircraft entered a stall profile shortly after takeoff due to pilot distraction from an ajar cabin door in instrument meteorological conditions, resulting in a forced landing.

What happened

The aircraft crashed shortly after takeoff while operating in instrument meteorological conditions (IMC). The flight was disrupted by a distraction caused by a cabin door being left ajar. This distraction, combined with the challenging solid IFR flight conditions, resulted in the aircraft entering a stall profile.

Following the loss of control, the pilot executed a forced landing into an open field. The event occurred during the initial climb phase of flight immediately after departure.

The investigation

A thorough examination of the aircraft and its engine was conducted to determine the mechanical status prior to the incident. The inspection failed to reveal any pre-impact malfunction or failure of the airframe or propulsion system. The structural integrity of the aircraft appeared consistent with a controlled impact following an aerodynamic stall rather than a mechanical breakdown.

Findings

The primary factors contributing to the accident were the pilot's distraction from the ajar cabin door and the prevailing solid IFR flight conditions. These elements combined to cause the aircraft to enter a stall profile during a critical phase of flight. The pilot's subsequent decision to execute a forced landing in an open field was a direct response to the loss of lift.

Safety message

Pilots operating in instrument meteorological conditions must maintain strict discipline regarding cabin security and external distractions. Ensuring all doors are securely latched prior to takeoff is essential to prevent critical interruptions during low-altitude operations where recovery margins are minimal.

Probable cause

The pilot's distraction from a cabin door left ajar, which contributed to the aircraft entering a stall profile in instrument meteorological conditions.
