Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

A sheared mixture cable which resulted in a loss of engine power.

Analysis

After returning to the airport following a successful cross country flight the student did a touch and go. Shortly after the touch and go a flight instructor who had departed the airport in another airplane heard the student pilot state on the radio frequency that he was having engine trouble. The flight instructor asked the student pilot's position, then advised the student pilot to maintain glide airspeed and turn toward the airport. The flight instructor heard the student pilot state over the radio that he could not make it to the airport and was going into trees. The wreckage was found approximately 1,700 feet west southwest of the approach end of runway 36 in a wooded residential area. Examination of the airplane found the mixture control separated at or near the mounting bracket, adjacent to the carburetor. The inner cable strands were worn; the outer cable sleeve was corroded. Visual examination of the broken wire ends with the aid of an optical microscope revealed that all of the wires had severe wear, and that most were worn completely through before the final fracture.

History of flight

On September 23, 2002, at 1830 central daylight time, a Piper PA-28-140, N8828N, registered to and operated by Aircraft Partners of Milton, collided with trees following a loss of engine power in Milton, Florida. The instructional flight was operated under the provisions of Title 14 CFR Part 91 and visual flight rules. visual meteorological conditions prevailed and a visual flight rules (VFR) flight plan was filed. The student pilot received fatal injuries, and the airplane sustained substantial damage. The flight departed Monroe County Airport in Monroeville, Alabama, on September 23, 2002, at about 1755.

The student pilot departed Peter Prince Field in Milton, Florida, for a solo roundtrip flight to Monroeville, Alabama. The student pilot completed the round trip flight and elected to execute a touch-and-go upon returning to Milton, Florida. An airframe and power plant mechanic at the airport saw the airplane execute a touch-and-go on runway 36, then climbed through 500 feet and turned left crosswind then left downwind in the traffic pattern. The mechanic stated the airplane's engine sounded smooth, and the touch-and-go appeared normal. A flight instructor who had departed the airport in another airplane heard the student pilot transmit on the UNICOM radio frequency that he was having "engine trouble." The flight instructor asked the student pilot's position, then advised the student pilot to maintain glide airspeed and turn toward the airport. The flight instructor heard the student pilot state over the radio that he could not make it to the airport and was going into trees.

The wreckage was found approximately 1,700 feet west southwest of the approach end of runway 36 in a wooded residential area. The nose of the airplane was crushed against the base of a large tree adjacent to a mobile home, and the airplane came to rest in a steep, nose-down position between the tree and the home.

Personnel information

A review of information on file with the Federal Aviation Administration (FAA) Aero Medical Records Division, Oklahoma City, Oklahoma, revealed that the student pilot held a third class medical certificate issued on August 21, 2002. The student pilots log book indicated that he had accumulated at total time of 25.0 hours all of which were gained in the last 30 days with three hours having been gained in the last 24 hours. The log book also indicated that the student pilot had accumulated four hours as pilot-in-command.

The student pilot was an active duty Marine, and was enrolled in the Navy's new Initial Flight Screening (IFS) program. This program was designed to screen applicants for Navy Flight Training. The Navy requirements for completion of the IFS program, was that every student must solo before the 15-hour mark and within 36 days of enrollment; All students must complete IFS within 60 days of enrollment; Every student must successfully fly at least three solos (one as a solo cross-country) and 2 solo hours before the 25-hour mark; every student must complete all ground instruction and associated examinations prior to the solo cross-country. This was the student pilot's last flight before successfully completing the IFS program. An interview was conducted with the Flight Schools Lead Flight Instructor who stated that during the students short time with the school, the focus of the flight training was on getting the student to solo and complete their required cross country flights. She stated that they do cover emergency procedures in the beginning of their flight training, but emergency procedures were not the focus of their training.

Aircraft information

A review of maintenance records revealed that the last annual inspection was completed on September 19, 2002, 6.21 hours prior to the accident, and a total airframe time of 7,319.0 hours, total engine time of 4,424.9 hours, and 737.6 hours since factory overhaul. The review of the engine maintenance logs showed that the engine was last overhauled on October 3, 2000.

Wreckage and impact information

The examination of the accident site found that the wreckage debris was contained within the impact point between a modular home and a large tree. The tree displayed heavy scrapes and gouging approximately 10 to 15 feet above the ground. Fuel was observed leaking from the wreckage. Approximately five gallons of fuel was recovered from the left tank, and approximately nine gallons of fuel was recovered from the right tank. Property damage to the house was minimal. The accident site was located in a residential area adjacent to the airport that corresponds approximately with the left downwind-to-base position for landing on runway 36. The wreckage was orientated on a 082-degree magnetic heading towards runway 36. The airplane wreckage as observed was in a left wing nose low position, with the empennage nearly resting against the rear corner roof of the house. The right wing had roofing material transferred to it from contacting the roof during the mishap sequence.

Examination of the left wing found it attached to its attachment points. The top outboard wing had impact damage and was bent upward approximately three feet. This portion of the wing was resting on the ground. The gear had no damage. The fuel tank had no damage and the fuel cap was in place and intact. The fuel vent was field tested by blowing air through the vent line and it was clear. The aileron was buckled at the inboard hinge. The bell crank was attached and had no damage. The bell crank stops were in-place and intact. The aileron balance weight was attached. Aileron control continuity was established from the aileron to the control yoke with no interruptions. The flap was attached and damaged at the middle and inboard hinge. The flap was found in the down position, at approximately 40-degrees, according to the flap handle and visual observation of the flap.

Examination of the right wing found it attached to it attachment points. The leading edge was crushed aft to the forward spar, approximately two feet six inches from the wing root. The leading edge had upward impact damage three feet six inches from the tip. This area displayed chord wise scratches. The landing gear had no damage. The fuel tank had leading edge impact damage. The fuel cap was in-place and intact. The fuel vent was field tested by blowing air through the vent line. The fuel vent appeared to be clear of blockage. The aileron had no damage. The bell crank had no damage and the stops were in-place and intact. Aileron control continuity was established from the aileron to the control yoke with no interruptions. The flap was attached to all three hinges. The damaged flap push pull rod was separated near the inboard flap hinge. The push pull rod had impact damage. The inboard hinge displayed impact damage.

Examination of the vertical stabilizer found no damage. The rudder was attached to its attachment points. The rudder had impact damage and was bent. The rudder horn was attached and was bent.
