N9229Y

HISTORY OF FLIGHTOn February 20, 2013, about 1820 central standard time, a Maule MXT-7-180 airplane, N9229Y, was substantially damaged when it impacted a snow covered field in Parkers Prairie, Minnesota. The private pilot was fatally injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a business flight. Visual meteorological conditions prevailed for the flight and no flight plan was filed. The flight originated from the Greater Peoria Regional Airport (PIA), Peoria, Illinois at 1438. The intended destination was a private field in Ottertail, Minnesota.

The pilot was en route home following a business trip to PIA earlier in the week. According to the pilot's brother, the pilot contacted him via his cell phone during the flight. The pilot was also in contact with his wife during the flight via text messaging. The pilot reported being over the Quad Cities area around 1510. He sent a text message saying that he would be "flying over home" at 1825 and stated that he would land if it was light enough. The pilot later contacted his brother asking if the landing strip at the farm where they kept the airplane had been plowed. The pilot's brother responded that it was plowed and the pilot responded "OK." The pilot's brother stated he received this message at 1805 and it was the last contact he had with the pilot.

A witness, who lived on the property where the accident occurred, heard the airplane prior to the accident. He reported hearing a loud "pop" which he stated sounded like an engine backfiring followed by the sound of the impact. He went outside, saw the wreckage and stated he could smell fuel.

Another witness who lived about a ½ mile from the accident site reported seeing the airplane approach from the south and it flew over their property then made a left 180 degree turn. The witness stated it was dark at the time, but estimated the airplane's altitude to be about 30 feet above the ground. The airplane was traveling fast and the engine initially sounded normal, but it sputtered just prior to the airplane impacting the terrain. PERSONNEL INFORMATIONThe pilot, age 41, held a private pilot certificate with a single engine land airplane rating. He was issued a third class airman medical certificate on September 3, 2009. The pilot held a Medical Waiver Certificate- Statement of Demonstrated Ability, due to congenitally short arms and contractures at the joints. The pilot demonstrated his ability during a medical flight test in a Cessna 150. During the test the pilot flew the airplane from the right seat as his right arm was stronger than his left. The pilot's brother stated the pilot flew the accident airplane from the right seat.

The pilot's most recent logbook contained entries from October 19, 2004, through February 17, 2013. According to the logbook, the pilot had a total flight time of 539.1 hours, of which 53.4 hours were in the accident make and model of airplane. The pilot had recorded having 49.4 hours of night flight time. AIRCRAFT INFORMATIONThe accident airplane was a 1993 Maule MXT-7-180, serial number 14026C. It was a high wing, single-engine airplane, with fixed tricycle landing gear. The airplane was powered by a 180-horsepower Lycoming O-360-C1F reciprocating engine, serial number L-33266-36A. The airplane was issued a normal category airworthiness certificate on January 21, 1993. The pilot and his brother were co-owners of the airplane which they purchased on August 23, 2012.

The aircraft and engine logbooks showed that the last annual inspections were performed on October 18, 2012, at a tachometer time of 1,349.6 hours, and a Hobbs meter time of 1,496.8 hours.

In order to accommodate the pilot's medical condition, the throttle control was modified and the flap handle was extended. Logbook records show a new throttle friction lock was installed on August 30, 2012, and an EZ Flap extension, Supplemental Type Certificate SA02246LA, was installed on September 7, 2012.

According to records obtained from a fixed base operator (FBO) at PIA, the pilot requested the airplane be "topped off" and the airplane was fueled with 34 gallons of 100LL aviation fuel. FBO personnel reported that prior to departing PIA, the pilot preheated the engine and then flooded the engine during the attempted start up. They put the airplane in a hangar, removed, cleaned, and checked the spark plugs, checked the mag timing, and charged the battery. No anomalies were noted so they closed the cowling and the pilot was able to start the engine. The tachometer reading was noted as 1,376.1 on the invoice. The tachometer reading at the time of the accident was 1,380.2. METEOROLOGICAL INFORMATIONWeather conditions recorded by the Automated Surface Observing Systems (ASOS), located at the Chandler Field Airport (AXN), Alexandria, Minnesota, 27 miles south of the accident site were:

At 1753: wind 100 degrees at 5 knots, visibility 10 miles, clear sky conditions, temperature minus 13 degrees Celsius, dew point minus 19 degrees Celsius, and altimeter 30.35 inches of mercury.

The airplane continued to travel about 300 feet through the field, across a rural driveway, and into a wooded area where it came to rest. The wreckage path was along a 300 degree heading. First responders reported the smell of fuel was present near the main wreckage.

The initial impact was about five feet long and contained pieces of green glass similar to the right wing navigational light. Approximately 15 feet to the west of the initial impact mark was an impact mark that was 3 feet long. Directly in front of and perpendicular to this mark was an 18 inch long slash mark in the snow. Just west of the 3 foot long mark was another ground impact mark that was approximately 5 feet long. Numerous pieces of wreckage were scattered between the initial impact mark and the main wreckage. These pieces included sections of both wings, the right wing lift struts, the upper engine cowling, the propeller ring gear, the baggage door, the right wing auxiliary fuel tank, the right main landing gear, the nose gear, and the propeller. The left main landing gear and the inboard sections of both wings were located near the main wreckage.

The cockpit was destroyed by impact forces. The elevator trim control was set to a slight nose down trim setting. The trim cables were attached to the trim sprocket and were separated in the empennage. The flap control cables were attached to the flap control lever. The cables were separated at the pulleys in the fuselage. The aileron cables were connected to the chain drive which connected the control yokes. The chain drive remained connected to the left control yoke. The right control yoke was separated from the wreckage. The rudder control cables remained attached to the rudder crossover bar and the cables were separated in the aft fuselage area. The elevator control cables remained attached to the pulley chain in the cockpit and the cables were separated in the aft fuselage area. All of the separated control cables exhibited signatures consistent with overload separations. The fuel selector was positioned to the "Both" position. The fuel transfer switches were not located.

The empennage was separated from the fuselage aft of the seats. The vertical stabilizer tubing was intact. The top portion of the rudder was separated and found along the wreckage path. The rudder balance weight remained attached to the top of the rudder. The left horizontal stabilizer and elevator remained attached to the empennage. The outboard section of the left side of the elevator was bent. The inboard section of the right horizontal stabilizer remained attached to the empennage and the remainder of the stabilizer was destroyed.

Both lift struts on the left wing were attached to the wing and were pulled free of the fuselage. The fuselage attach bolts remained attached to the struts. Both bolts displayed signatures of overload.

The left flap remained attached to the wing at the two inboard attach points. The outboard attachment bracket was pulled from the flap. The right wing was separated into two sections just inboard of the outboard fuel tank. The inboard fuel tank remai...
