Aviation Accident Summary CHI03FA150

West Chicago, IL, USA

Aircraft #1

N13474

Cessna 172M

Analysis

The airplane stalled and impacted the terrain following a loss of directional control on takeoff. The student pilot reported he had been practicing soft field takeoffs and landings with his instructor. The student pilot's instructor exited the aircraft after the third landing. The student reported he then performed two solo soft field takeoffs and landings. The student pilot stated he was making his third takeoff at the time of the accident. The student pilot reported the airplane drifted to the right of the centerline, then he heard a sound and pitched up the nose of the airplane. The student pilot reported he then lost control of the airplane. The student pilot exited the airplane before it was consumed by a post-impact fire. A witness reported seeing the airplane in a 45 degree nose up attitude at a slow speed prior to it rolling to the left and impacting the ground.

Factual Information

HISTORY OF FLIGHT On June 7, 2003, at 1031 central daylight time, a Cessna 172M, N13474, operated by Illinois Aviation Academy, was destroyed by impact and post impact fire when it collided with the terrain while taking off on runway 28 (4,751 feet by 75 feet, asphalt), at Dupage Airport, West Chicago, Illinois. Visual Meteorological conditions prevailed at the time of the accident. The solo instructional flight was operating under the provisions of 14 CFR Part 91 without a flight plan. The student pilot was seriously injured. The student pilot was practicing takeoffs and landings at the time of the accident. The accident occurred on the third takeoff. The airplane departed for a dual instructional flight in the traffic pattern about 0930. On board at the time were the student pilot and his instructor. The student pilot was simulating soft-field landings on runways 20R and 20L. The instructor radioed the tower after the second landing and requested runway 28 for more favorable wind conditions. The student pilot conducted a third soft-field takeoff and landing. The flight instructor subsequently exited the aircraft. The student pilot then conducted two more soft-field takeoffs and landings. Following his second landing the solo student noticed the winds had shifted to the south. On the final take-off the student utilized ten degrees of flaps and applied backpressure to keep the weight off the nose landing gear. The student then leveled the airplane in ground effect and the airplane drifted to the right of the centerline. The student applied a crosswind correction and heard the right main landing gear strike an object. The student pitched up the nose of the airplane and subsequently lost control of the airplane. The pilot of an airplane holding short of runway 33 for takeoff reported seeing the accident airplane at a very low altitude over the airport in a 45 degree nose high attitude. According to the witness the airplane slowed and rolled to the left, subsequently impacting terrain, left wingtip first, and cartwheeled to a stop. The witness noted that the accident airplane caught fire several moments after it came to a stop. PERSONNEL INFORMATION The pilot held a student pilot certificate and a second-class medical certificate, which was issued on October 31, 2002. The last medical certificate contained the restriction, "Must wear corrective lenses." The pilot's logbook showed the pilot had 109 hours of total flight time and 6 hours of pilot in command time. The pilot also had received a 90-day solo endorsement from his flight instructor on April 22, 2003. AIRCRAFT INFORMATION The airplane was a Cessna 172M, serial number 17262777. The last annual inspection was performed on July 2, 2002, at a tachometer time of 6,263 hours. The engine was a 150 horsepower Lycoming O-320-E2D, serial number L-36096-27A. A 100-hour inspection was completed on the engine on May 22, 2003, at a tachometer time of 7,122.2 hours. An engine logbook entry showed an oil change was completed on June 5, 2003, at a tachometer time of 7,162 hours. According to Federal Aviation Administration records, N13474, was owned by Flying W Leasing. The airplane was being operated by Illinois Aviation Academy Inc. METEOROLOGICAL INFORMATION A weather observation station, located at the accident site, recorded the weather as: Time: 0953 Wind: 270 degrees magnetic at 6 knots Visibility: 10 statute miles Sky Condition: Sky Clear Temperature: 19 degrees Celsius Dew Point: 13 degrees Celsius Pressure: 29.81 inches of mercury Time: 1053 Wind: 200 degrees magnetic at 5 knots Visibility: 10 statute miles Sky Condition: Few Clouds at 3,300 feet above ground level Temperature: 21 degrees Celsius Dew Point: 13 degrees Celsius Pressure: 29.80 inches of mercury WRECKAGE AND IMPACT INFORMATION The National Transportation Safety Board's (NTSB) on-scene investigation began on June 7, 2003. The main wreckage was located on runway 28, about 60 feet east of runway 20R. The initial impact mark was located to the right side of runway 28. The general path of the ground scarring was on a magnetic heading of about 200 degrees. The main wreckage came to a rest on a magnetic heading of about 280 degrees. Several impact marks were located between the initial impact mark and the location of the main wreckage. The fuselage from the engine firewall to the tail was consumed by fire. Both wings sustained extensive fire damage and remained attached to the fuselage. The left wing of the aircraft was bent aft 90 degrees. The left flap and aileron were burned away and the right flap and aileron remained attached to the wing. The rudder, vertical stabilizer, elevator and horizontal stabilizer remained intact. Aileron, elevator, and rudder flight control continuity was established from the flight control surfaces and/or bellcranks to the cockpit. The fire destroyed all cockpit instrumentation, the fuel selector, and all of the engine controls. The engine sustained substantial impact and fire damage. It was remained partially connected to the firewall, although the engine mounts were extensively bent. The engine cowling remained mostly intact but did sustain substantial impact and fire damage. The propeller was attached to the engine with the spinner still intact with substantial impact damage. Both propeller blades were bent aft and twisted. MEDICAL AND PATHOLOGICAL INFORMATION The pilot sustained serious injuries and was taken to the hospital by emergency personnel. The pilot had a broken tibia and facial injuries. ADDITIONAL DATA/ INFORMATION The FAA was a party to the investigation.

Probable Cause and Findings

The abrupt pull-up initiated by the pilot during takeoff before airspeed was attained resulting in a stall. Factors contributing to the accident were the pilot's failure to maintain directional control of the airplane on takeoff and the crosswind.
