1992-12-23: Rockwell 690C (N81TR) — Casper Air Service — Golden, CO

Golden, CO, US

On December 23, 1992, a Rockwell 690C (registration N81TR) operated by Casper Air Service was involved in an aviation accident near Golden, CO. Investigators recorded the probable cause as: THE PILOT FLYING THE AIRCRAFT BEYOND THE DESIGN MANEUVERING SPEED AND EXCEEDING THE DESIGN STRESS LIMITS. A FACTOR WAS: CLEAR AIR TURBULENCE. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 6 related events involving the same aircraft type or operator are linked below.

An aircraft experienced structural failure during descent, with the right outer wing, horizontal stabilizer, and vertical stabilizer separating. The aircraft impacted about 10 miles from the destination. Radar data indicated descent at Vne with known severe turbulence.

Accident Overview

An aircraft sustained a structural failure while descending for arrival at its destination airport. The failure resulted in the separation of the right outer wing, horizontal stabilizer, and vertical stabilizer from the airframe. The aircraft subsequently impacted terrain approximately 10 miles from the planned destination.

Sequence of Events

According to radar data and other research, the descent was conducted at Vne (never-exceed speed). Known severe turbulence was present in the area at the time of the accident. The structural failure occurred during this phase of flight, leading to the separation of major aerodynamic surfaces.

Damage and Impact

The aircraft was destroyed upon impact. The separated components—the right outer wing, horizontal stabilizer, and vertical stabilizer—were found in the debris field. The exact condition of other aircraft parts has not been detailed in available records.

Operational Factors

Radar data showed that the aircraft's descent speed exceeded its design limits. Additionally, severe turbulence had been reported in the vicinity. These conditions are considered significant in the context of the structural failure.
