On December 15, 1984, a Beech C23 (registration N2074X) operated by Huntsville Aviation was involved in an aviation accident near Athens, AL. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 2 related events involving the same aircraft type or operator are linked below.
An aircraft performing training stall maneuvers was observed in a steep right descending turn before impacting the ground with its right wing tip. The aircraft burned after impact. Evidence indicated low engine power and carburetor icing conditions.
Accident Sequence
Shortly before the accident, the aircraft was observed conducting training stall-type maneuvers in the area. Witnesses subsequently saw the aircraft in a steep right descending turn, crossing a paved road at low altitude. The right wing tip struck the ground, followed by the bottom of the aircraft nose hitting the ground and then a low road embankment. The aircraft caught fire after the final impact.
Post-Impact Fire and Engine Power
Examination of the wreckage revealed that the aircraft burned after the impact sequence. Evidence from the scene indicated that the engine was producing low to no power at the time of impact.
Carburetor Icing Conditions
The ambient atmospheric conditions at the time were favorable for carburetor ice formation. Investigators found the carburetor heat controls in the cold position. Icing probability curves indicated that serious carburetor icing could occur after 15 minutes of continuous operation under the existing conditions.
