Short Final Downdraft Causes Hard Landing (N87AD)

Fort Pierce, FL, US

On May 6, 2004, a Beech H35 (registration N87AD) operated by Tim Sullivan was involved in an aviation accident near Fort Pierce, FL. Investigators recorded the probable cause as: The pilot's failure to maintain adequate airspeed and control during a sudden downdraft on short final, resulting in a hard landing. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot encountered a sudden downdraft on very short final, driving the aircraft downward and resulting in a hard landing short of the runway beginning with substantial damage.

What happened

The pilot reported that during the approach phase, specifically while established on very short final, the aircraft was subjected to a sudden and significant downdraft. This meteorological condition drove the airplane downward more rapidly than anticipated. Consequently, the aircraft impacted the ground with substantial force short of the beginning of the runway threshold.

The investigation

Post-acc examination revealed that the airplane incurred substantial damage as a direct result of the hard landing impact. A review of the aircraft's condition prior to the event indicated that there were no mechanical failures or malfunctions affecting the airplane or any of its systems. The pilot confirmed that the aircraft was airworthy and functioning normally before the encounter with the downdraft.

Findings

The primary factor contributing to the accident was the sudden downdraft encountered on final approach. This weather phenomenon caused an excessive descent rate, leading to the hard landing outside the runway environment. The absence of mechanical issues confirms that the event was driven by external atmospheric conditions rather than equipment failure.

Probable cause

The pilot's failure to maintain adequate airspeed and control during a sudden downdraft on short final, resulting in a hard landing.
