Aviation Accident Summary CEN17LA282

Wichita Falls, TX, USA

Aircraft #1

N4216D

BEECH G35

Analysis

The airline transport pilot stated that the cross-country personal flight proceeded normally until he entered the downwind leg for landing. During the landing approach in dark night conditions, he noted scattered thunderstorms ahead. During the final approach, he thought the airplane was too high, and he considered conducting a go-around. The airplane encountered a strong downdraft, heavy rain, and turbulence, and the pilot saw several lightning strikes ahead. The pilot decided to land and risk overrunning the runway rather than possibly entering the thunderstorm. Upon landing, the airplane overran the end of the runway, the second half of which had standing water on it, and then struck a berm. An automated weather observation facility 7 miles east of the accident site reported, at the time of the accident, variable winds from between 060° and 360° at between 16 and 20 knots, gusting to between 21 and 29 knots with a peak wind of 35 knots. A thunderstorm was present near the airport with lightning observed in all quadrants.

Factual Information

On July 23, 2017, about 2230 central daylight time, a Beech G35, N4216D, was substantially damaged when it struck an irrigation canal off the end of runway 13 at Wichita Valley Airport (F14), Wichita Falls, Texas. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 without a flight plan. The pilot, the sole occupant aboard, was seriously injured. The local flight originated from Grand Prairie (GPM), Texas, about 2130.According to the pilot's accident report, he departed GPM about 2130, and received flight following and a clearance into Class B airspace. The flight proceeded normally until he entered the downwind leg for runway 13 at F14. He noted scattered thunderstorms ahead. On final approach, he thought the airplane was too high and he considered making a go-around. He felt strong downdraft and encountered heavy rain and turbulence. He also observed several lightning strikes ahead. The pilot made the decision to land and risk running off the end of the runway rather than possibly entering the thunderstorm. The pilot said he did not realize there were 6-foot tall berms on either side of a drainage ditch 50 to 60 feet from the end of the runway because of the tall weeds obscured them. There was also standing water on the second half of the runway. The airplane went off the end of the runway and struck the first berm. The impact rendered the pilot unconscious. When he regained consciousness minutes later, the airplane was in a drainage ditch and water had filled the cockpit. He remained in the airplane until daylight, extricated himself, and walked to a nearby house where he called 9-1-1. Federal Aviation Administration (FAA) inspectors examined the airplane and reported finding substantial damage to the forward fuselage and firewall. Weather observations recorded at Sheppard Air Force Base/Wichita Falls Municipal Airport (SPS), located 7 miles to the east of F14, reported winds varying from 060° to 360° at 16 to 20 knots, and gusting from 21 to 29 knots, with a peak wind at 35 knots. There was a thunderstorm in the vicinity, with lightning observed in all quadrants.

Probable Cause and Findings

The flight's encounter with adverse weather conditions at night, which resulted in the pilot's loss of airplane control upon landing due to standing water and a subsequent runway overrun.
