1994-03-01: Cessna 177RG (N2181Q) — Debruzzi, Michael S. — Longmont, CO

Longmont, CO, US

On March 1, 1994, a Cessna 177RG (registration N2181Q) operated by Debruzzi, Michael S. was involved in an aviation accident near Longmont, CO. Investigators recorded the probable cause as: The pilot's failure to remove ice from the aircraft prior to takeoff, which resulted in a stall during initial climb. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft stalled during initial climb after takeoff, impacting terrain off the runway end. Investigation confirmed ice on all surfaces due to improper deicing by the pilot.

What happened

The accident occurred during the initial climb phase immediately following takeoff. The aircraft experienced an aerodynamic stall and subsequently impacted terrain located just beyond the end of the departure runway. Local law enforcement officers responded to the scene within twenty minutes of the crash. Their examination of the wreckage provided critical physical evidence regarding the condition of the aircraft prior to impact.

The investigation

A thorough inspection of the accident site revealed significant ice accumulation on all exterior surfaces of the aircraft. This finding was corroborated by the pilot's own admission that he had failed to properly remove ice from the airframe before flight. The presence of ice on critical lifting and control surfaces likely degraded aerodynamic performance, contributing directly to the stall during a low-altitude maneuver.

Findings

The primary factor in this accident was the pilot's failure to adequately deice the aircraft prior to departure. Operating an aircraft with ice accumulation is prohibited under standard aviation safety protocols due to the severe loss of lift and increase in drag it causes. The combination of a stall during the critical initial climb phase and the presence of ice confirms that inadequate preflight preparation was the central cause of the crash.

Safety message

Pilots must ensure that all ice, snow, and frost are completely removed from aircraft surfaces before flight. Even small amounts of contamination can significantly alter airflow and reduce lift, leading to loss of control at low speeds.

Probable cause

The pilot's failure to remove ice from the aircraft prior to takeoff, which resulted in a stall during initial climb.
