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.
