What happened
The airplane touched down on a dirt strip and traveled approximately 300 feet before encountering a soft, muddy area that extended about 6 to 8 feet along the runway. Upon entering this section, the nose gear collapsed, causing the aircraft to nosed over.
Prior to the landing, the pilot conducted two low passes over the strip. During these passes, he observed existing tire tracks on the surface and determined that the conditions were suitable for a landing.
The investigation
The investigation focused on the physical evidence at the site of the accident. Investigators noted the specific location where the nose gear failed and the extent of the soft, muddy area that contributed to the collapse.
