Des Moines, IA, US

On March 3, 1989, a Cessna 310 (registration N5119C) was involved in an aviation accident near Des Moines, IA. Investigators recorded the probable cause as: The pilot's perception of altitude was distorted by high-intensity runway lights, combined with a hard landing following an approach at higher speeds due to ice accumulation. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft experienced a right main gear collapse and veered off the runway during its third landing attempt under low visibility and icing conditions.

What happened

During a night approach in darkness, an aircraft attempted to land for the third time following two previous go-arounds. The weather at the time consisted of a 500-foot ceiling, 1.5 miles of visibility, and light freezing drizzle.

Upon landing, the aircraft experienced a hard impact that resulted in the collapse of the right main gear, causing the aircraft to veer off the runway. The pilot reported using an approach speed higher than normal to account for the weight of ice accumulation on the airframe, as deicing equipment was being utilized during the flight.

According to the pilot, the control tower had increased the intensity of the runway lights to assist with visual contact. However, the pilot stated that these bright lights caused optical distortion and created the illusion of being lower than the actual altitude.

Probable cause

The pilot's perception of altitude was distorted by high-intensity runway lights, combined with a hard landing following an approach at higher speeds due to ice accumulation.
