CHI99LA280

The aircraft was destroyed on impact with power lines and post accident fire following an aborted landing on runway 01 (1,895 feet by 100 feet, turf) at Gainsville Memorial Airport (H27), Gainsville Missouri. In a written statement, the pilot reported the following: '... touched down on runway retracted flaps hit bump left wheel then bump rt wheel. Saw house at end of runway added power and 10 degrees of flaps for go around. Retracted gear established climb speed during climb experienced partial loss of power. Unable to continue climb hit top of trees then in electric pole landed a/c on blacktop road a/c burned on road.' Examination of the aircraft wreckage revealed no mechanical anomalies. The Marrion County Regional Airport, located approximately 21 nmi southwest of H27, reported, at 1215, a temperature of 91 degrees F or 33 degrees C; wind from 220 degrees at 6 knots; and an altimeter setting of 29.98 inches of mercury. At an approximate pressure altitude of 1,000 feet, outside air temperature of 33 degrees C, gross weight of 2,700 lbs, 6 kt tailwind wind component, and 50 ft obstacle; the Mooney M20J, 'Normal Landing Distance-Grass Surface', chart depicts a landing distance of approximately 3,300 feet.

On August 7, 1999, at 1211 central daylight time, a Mooney M20J, N11652, piloted by a private pilot, was destroyed on impact with power lines and post accident fire following an aborted landing on runway 01 (1,895 feet by 100 feet, turf) at Gainsville Memorial Airport (H27), Gainsville Missouri. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 personal flight was not operating on a flight plan. The pilot and passenger sustained serious injuries. The flight originated from the North Little Rock Municipal Airport, North Little Rock, Arkansas, at 1045.

In a written statement, the pilot reported the following: "Ck. wind sock by fly over entered downwind leg-base-final realized airspeed too high did go around and reentered down wind-base-final with lower airspeed touched down on runway retracted flaps hit bump left wheel then bump rt wheel. Saw house at end of runway added power and 10 degrees of flaps for go around. Retracted gear established climb speed during climb experienced partial loss of power. Unable to continue climb hit top of trees then in electric pole landed a/c on blacktop road a/c burned on road."

Inspection of the aircraft revealed that the landing gear and wing flaps were in their retracted positions. The engine was rotated and a thumb compression was obtained. Continuity through the engine and accessory section was established. The throttle and mixture controls were intact and continuity to the cockpit was established. The fuel injection servo, fuel inlet screen and induction system were unobstructed. Examination of the engine driven pump revealed that the pulsator diaphragm was intact and the pump was unobstructed.

There were black helical scratches on the propeller spinner and chordwise striations across the propeller blades.

The Marrion County Regional Airport, located approximately 21 nmi southwest of H27, reported, at 1215, a temperature of 91 degrees F or 33 degrees C; wind from 220 degrees at 6 knots; and an altimeter setting of 29.98 inches of mercury.

The Airport/Facility Directory states, under airport remarks for H27, the following: "...All rwys have brush, trees, roads, buildings and utility poles and lines in appch areas. Short roll out distances from displcd thlds to rwy ends..." Runway 01 has a 640-foot displaced threshold and runway 19 has a 400-foot displaced threshold.

Federal Aviation Administration (FAA) Publication, FAA-P-8740-7,8(b), The Safe Pilot's 12 Golden Rules, states, "...Be sure the runway length is equal to aircraft manufacturer's published takeoff or landing distance plus...80% safety margin if hard surface, double the manual distance if sod, and triple the distance if wet grass (about the same traction as ice)..."

At a approximate pressure altitude of 1,000 feet, outside air temperature of 33 degrees C, gross weight of 2,700 lbs, 6 kt tailwind wind component, and 50 ft obstacle; the Mooney M20J, "Normal Landing Distance-Grass Surface", chart depicts a landing distance of approximately 3,300 feet.

The FAA and Textron Lycoming were parties to the investigation.
