Accident
On February 24, 2016, about 1300 Pacific standard time, a Cessna 152, registration N152LC, sustained substantial damage when it veered off the runway and nosed over during landing at Pullman/Moscow Regional Airport (PUW), Pullman, Washington. The private pilot, the sole occupant, was not injured. The airplane was registered to and operated by Inter-State Aviation Inc. under 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed, and no flight plan was filed for the local flight that originated from PUW at 1215.
Pilot Account
According to a written report from the pilot, after practicing maneuvers in the local flying area, he returned to PUW and executed a touch-and-go landing with no incident. During his second landing, about 3 to 5 seconds before touchdown, at about 20 feet above ground level, the stall warning horn sounded briefly. The airplane touched down in a flat, three-point landing attitude. Subsequently, the nose gear collapsed, and the airplane started to veer to the right. The pilot applied left rudder and left brake; however, the airplane continued to veer off the runway into mud and nosed over.
Post-Accident Examination
The Federal Aviation Administration Inspector examined the airplane and confirmed that the nose gear had collapsed. The nose gear steering rods were removed and sent to the National Transportation Safety Board Materials Laboratory for analysis. Examination of the four pieces of tubes from the nose gear steering rods revealed that the fracture faces were mostly on a slant plane and contained features typical of overstress separation with no evidence of pre-existing damage such as corrosion or fatigue cracking. No other evidence of pre-impact mechanical malfunctions was revealed that would have prevented normal operation.
