Mexia

The pilot in the multi-engine, retractable landing gear airplane reported that, during an instrument flight rules cross-country flight, about 5,000 ft above mean sea level, the left engine surged several times and he performed an emergency engine shutdown. Shortly afterward, the right engine lost power. During the emergency descent, the airplane struck treetops, and landed hard in a field with the landing gear retracted. The airplane sustained substantial damage to both wings, the engine mounts, and the lower fuselage. The pilot reported that he had requested 200 gallons of fuel from his home airport fixed base operator, but they did not fuel the airplane. The pilot did not check the fuel quantity during his preflight inspection. According to the Federal Aviation Administration Airplane Flying Handbook, Chapter 2, page 2-7, pilots must always positively confirm the fuel quantity by visually inspecting the fuel level in each tank. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The 700-hour private pilot flying the twin-engine airplane with four passengers aboard used approximately three-quarters of runway 18 before becoming airborne. After establishing a positive rate of climb, the pilot retracted the landing gear and pitched the airplane for a 92 knot climb. Shortly thereafter the rate of climb decreased and the airplane's control authority began to decay. The pilot responded by applying full throttle to both engines and reduced the angle of attack in an attempt to regain airspeed. The pilot was able to arrest the airplane's decaying airspeed and descent; however, the airplane collided with a barn and then a grassy field before coming to rest in an upright position. The pilot and passengers were able to egress the airplane unassisted and the airplane was engulfed in flames a few minutes later. About 23 minutes after the mishap the weather reporting station 24 miles north of the accident site reported, the wind from 230 degrees at 6 knots, the temperature 84 degrees Fahrenheit, and dew point of 60 degrees Fahrenheit. Runway 18 was reported as a 4,002-foot long by 60-foot wide asphalt runway with trees near the departure end. The field elevation at the airport was reported at 544 feet and the density altitude was calculated at 1,860 feet. The estimated weight of the airplane at the time of departure was near its maximum gross weight of 6,000 pounds. The pilot reported that he had not performed a weight and balance check, calculated density altitude, and was not sure of how much fuel was onboard the airplane prior to departure. The pilot further reported that there were no apparent anomalies with the airplane.

The pilot arrived at Mexia-Limestone County Airport (TX06), Mexia, Texas, sometime before 1100. Once onboard the airplane, a witness, and an acquaintance of the pilot, closed and locked the airplane's cabin door for the pilot, and walked away from the airplane. He also reported that after the engines to the airplane were started, the airplane stayed on the ramp and idled for 10 to 15 minutes. No one saw the pilot taxi to the runway, but he taxied to the north end of Runway 18 for a downwind takeoff to the south. Examination of the accident site found the wreckage oriented along a path consistent with an extended centerline of runway 18. The airplane was found along a fence line approximately 1/4 mile from the departure end of Runway 18. The airplane's track was along a 183-degree bearing, and there was a large burn area prior to and around the debris zone along the wreckage path. Examination of the cockpit revealed a 9/16-inch hex-head bolt inserted in the control lock pinhole for the control column. Under normal procedures Cockpit Check in the Duke 60 Airplane Flight Manual, for Preflight Inspection the first item listed is: 1. "Control Locks - REMOVE and STOW". In addition, under normal procedures Before Starting checklist in the Duke 60 Airplane Flight Manual, the fourth item to check is listed as: 4. "Flight Controls - FREEDOM OF MOVEMENT and PROPER RESPONSE"
