DEN03LA134

According to the pilot's statement, he arrived at Logan at 1830. When he checked the weather, the temperature was 90 degrees and the calculated density altitude was approximately 7,000 feet. There was no wind, but an airport employee suggested using runway 35. Although the pilot had some difficulty starting the engine, all pre take-off checks were normal, and the airplane ran fine. During the taxi to runway 35, the pilot noticed that the wind was from 050 degrees at 15 knots, and he elected to use runway 17. The pilot stated that he leaned the mixture to 2,200 rpm, accelerated to 80 knots, and rotated. Following rotation, the airplane continued to accelerate, but would only climb approximately 20 to 25 feet above the runway. The pilot adjusted the mixture and attempted to add more power but the engine would not respond. With no runway remaining, he continued on the departure heading and made a forced landing in a field just past the end of the runway. An examination of the airplane's systems revealed that the airplane was full of fuel, the throttle was at idol, the mixture was lean, the propeller was at high rpm, and the flaps were in the retracted position. Although the landing gear selector lever was in the "up" position, the ground scars at the initial impact point, and the damage to the landing gear, were consistent with the landing gear being in the extended position. An examination of the engine revealed that all the spark plugs were worn in a "football" shape. The shielding was exposed on the number 5 cylinder's bottom spark plug wire. A "small hole, approximate size of a pencil tip" was located on the manifold pressure tube for the number 5 cylinder. The propeller pitch control was found full forward and in contact with the pedestal stop prior to the governor stop, which would "restrict its travel to full rpm by 1/8 inch. With the engine and controls in this condition, it would not be possible for the engine to make the take-off rpm of 2,700.

On July 18, 2003, at 1750 mountain daylight time, a Piper PA-32R-301, N8036D, operated by the pilot, was substantially damaged when it impacted terrain during a forced landing following take-off from Logan-Cache Airport (LGU), Logan, Utah. The private pilot, and his 5 passengers were not injured. Visual meteorological conditions prevailed. No flight plan had been filed for this personal flight being conducted under Title 14 CFR Part 91. The flight was originating at the time of the accident.

According to the pilot's statement, he arrived at Logan at 1830. When he checked the weather, the temperature was 90 degrees and the calculated density altitude was approximately 7,000 feet. There was no wind, but an airport employee suggested using runway 35. Although the pilot had some difficulty starting the engine, all pre take-off checks were normal, and the airplane ran fine. During the taxi to runway 35, the pilot noticed that the wind was from 050 degrees at 15 knots, and he elected to use runway 17.

Following rotation, the airplane continued to accelerate, but would only climb approximately 20 to 25 feet above the runway. The pilot adjusted the mixture and attempted to add more power but the engine would not respond. With no runway remaining, he continued on the departure heading and made a forced landing in a field just past the end of the runway. The pilot said that he "did not have time to lower the landing gear."

The pilot stated that during the pre-takeoff checks, there was a 200 rpm drop for each magneto check, the manifold pressure was set to 25 inches, and the oil pressure was slightly higher than normal. The pilot also stated that, on July 15, 2003, just prior to his flight to Logan, he refueled the airplane at Montgomery Field in San Diego, California. He had difficulty refueling because the self-serve pump kept shutting off. An airport employee mentioned that the pump does that when the filter is dirty. The pilot requested fuel, and a fuel truck was sent out to put 30 gallons of fuel in each side. The pilot said that prior to departing Montgomery Field, he noticed a slight amount of water in his right tank.

One witness stated that he heard the engine "backfire" as it was being started. A second witness stated that the airplane['s engine] sounded like it was "missing" or running rough. As if flew over the road, "almost striking traffic." A third witness stated that the airplane "appeared to have taken off with a 10 to 20 knot tail wind."

For July 18, 2003, the last recorded weather observations for Logan was taken at 1357. The recorded data was; wind, 6 mph; visibility, 10 statute miles; temperature, 98 degrees F.; dew point, 48 degrees F; altimeter setting, 30.15. At that time, the calculated density altitude was 6,973 feet. There was no recorded wind direction.

According to an FAA airworthiness inspector, the airplane struck the ground approximately 1/4 mile from the departure end of runway 17. The airplane rotated clockwise approximately 140 degrees, and slid about 115 feet from the initial impact point. The impact tore off the right main landing gear, displaced the airplane's right wing, collapsed the nose landing gear, and buckled the firewall. An examination of the airplane's systems revealed that the airplane was full of fuel, the throttle was at idol, the mixture was lean, the propeller was at high rpm, and the flaps were in the retracted position. Although the landing gear selector lever was in the "up" position, the ground scars at the initial impact point, and the damage to the landing gear, were consistent with the landing gear being in the extended position. An examination of the engine revealed that all the spark plugs were worn in a "football" shape. The shielding was exposed on the number 5 cylinder's bottom spark plug wire. A "small hole, approximate size of a pencil tip" was located on the manifold pressure tube for the number 5 cylinder. The propeller pitch control was found full forward and in contact with the pedestal stop prior to the governor stop, which would "restrict its travel to full rpm by 1/8 inch. With the engine and controls in this condition, it would not be possible for the engine to make the take-off rpm of 2,700.
