Casualties unknown

Aircraft sustains substantial damage in hard landing following icing encounter (N5985C)

Ankeny, IA, US

On March 4, 2002, a Beech D35 (registration N5985C) was involved in an aviation accident near Ankeny, IA. Investigators recorded the probable cause as: The pilot's inability to maintain control due to an early stall during the landing flare, which was influenced by ice accumulation on the airplane from prior icing conditions. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft experienced significant structural damage after a hard landing, which occurred shortly after the pilot encountered icing conditions and reported ice accumulation on the airframe.

What happened

The airplane sustained substantial damage during a hard landing event. Prior to this incident, the pilot had returned to the departure airport due to encountering icing conditions along the intended route of flight. The pilot reported that ice accumulation was present on the airplane at the time.

During the approach for landing, the airplane stalled early in the flare phase. This stall contributed directly to the hard touchdown that resulted in the damage to the airframe.

The investigation

The investigation focused on the circumstances surrounding the landing and the reported environmental conditions. Examination of the pilot's account confirmed the presence of icing conditions during the flight and subsequent ice accumulation on the aircraft structure.

Findings

Contributing factors to the accident included the encounter with icing conditions, which led to ice accumulation on the airplane. This condition likely affected aerodynamic performance, leading to an early stall during the landing flare. The pilot's decision to return to the departure airport was made in response to these hazardous weather conditions.

Safety message

Pilots should be aware of the significant risks associated with flying in icing conditions. Ice accumulation can degrade aircraft performance and control characteristics, potentially leading to stalls at low altitudes during critical phases of flight such as landing.

Probable cause

The pilot's inability to maintain control due to an early stall during the landing flare, which was influenced by ice accumulation on the airplane from prior icing conditions.
