Probable cause

The pilot's poorly planned approach for not planning the intended touchdown point farther down the runway to avoid an area of known turbulence caused by terrain. Contributing to the accident was the turbulence.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot stated that the approach to the runway, known to have turbulence during windy conditions as experienced, was normal. While on short final with 1/2 flaps extended, the airplane began an uncommanded descent, then touched down about 60 feet past the runway threshold. The main landing gear collapsed and the propeller contacted the runway. The pilot then applied power but damage to the propeller had occurred. The airplane then veered off the runway and came to rest upright. The pilot further stated that there was no engine or airframe failure or malfunction, and due to the known turbulence she should have planned to land farther down the runway.

Factual narrative

On June 8, 1998, about 0806 eastern daylight time, a homebuilt Wittman Tailwind W10, N173RS, registered to a private individual, experienced collapse of the main landing gear and collision with bushes during landing at the Spruce Creek Airport, Daytona Beach, Florida. Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14 CFR Part 91 personal flight. The airplane was substantially damaged and the private-rated pilot, the sole occupant, was not injured. The flight originated about 15 minutes earlier.

The pilot stated that the airspeed on final approach was normal, and during short final with 1/2 flaps extended, the airplane descended rapidly and touched down collapsing the main landing gear and damaging the propeller. The airplane bounced and she applied power but the propeller had been damaged. Then, while airborne, the airplane collided with bushes off the left side of the runway. She further stated that there was no engine or airframe preimpact failure or malfunction and she had known about turbulence created by the wind and trees on the approach end of the runway. When responding in writing to how could this accident have been prevented she wrote, "extend landing point further down the runway-avoiding area known to have gust area."

According to the airport manager who examined the airplane and runway, the first point of impact on the runway was noted to be about 60 feet past the threshold. The airplane came to rest at a point about 150 feet past the runway threshold as measured down the runway centerline.
