NTSB description


On December 20, 2002, at 1957 eastern standard time, a Piper PA-32-300, N47420, registered to and operated by Alpha II Zulu Incorporated, flown by a private pilot, collided with trees during an emergency descent. The personal flight was operated under the provisions of Title 14 CFR Part 91 with an instrument fight plan filed. Visual meteorological conditions prevailed at the time of the accident. The airplane was destroyed, and the pilot and three passengers were fatally injured; one passenger received minor injuries. The flight originated from Columbus, Ohio, on December 20, 2002 at 1639 central standard time.

The pilot was on an instrument cross-country flight from Columbus, Ohio, and at 1937, initial contact was established with the Atlanta Approach Control. At 1949, the pilot declared he had an emergency. At 1950, approach control advised the pilot that the Macon Regional Airport was twelve o'clock and 15 miles. Approach control asked the pilot if he would be able to make it to the airport. The pilot advised that he could get to the airport, and requested a heading. Approach control gave the pilot a heading of 180 and asked for the nature of the emergency. The pilot advised that he thinks he just lost his engine and had smoke in the cockpit. Approach control advised the pilot to turn towards the Herbert Smart Airport at his eleven o'clock and 13 miles. Approach control advised the pilot that the airport was at his 12 to 11 o'clock position and ten miles. Approach control asked the pilot if he could hold attitude. The pilot responded negative and he would try to maintain 4,500 feet. At 1954, the pilot was advised that I-75 was off to his right side. The pilot responded that he was at 2,200 feet and not sure that he could hold altitude. At 1954, the pilot advised approach control that he had a "total lost of engine power", and advised approach control that he would not be able to make the airport and that he was at 1,600 feet. At 1956, approach control lost radar contact one mile north of the interstate interchange.

According to the passenger the engine stopped and the pilot attempted to restart the engine. After an unsuccessful attempt to restart the engine the airplane seemed as though it was "sailing down". The pilot told the passengers to brace themselves because they were going to hit some trees. The airplane collided with trees and came to rest in a heavily wooded area. The passenger attempted to pull one of the other passengers out of the airplane; but the airplane burst into flames. The passenger ran for help at a nearby store, and requested emergency assistance. On returning to the wreckage site the airplane had been fire damaged.


The pilot was issued a private pilot certificate on June 28, 2000, with ratings for airplane single engine land, and instrument airplane. Review of records revealed the pilot held a third-class medical certificate issued on August 15, 2001, valid when wearing corrective lenses. The pilot reported on his application for the medical certificate that he had accumulated 426 total flight hours. The pilot's logbook was not recovered for review.


The last recorded annual inspection was conducted on September 20, 2002; the total tachometer time was 3271.94. The altimeter system, static pressure system, and transponder were inspected on August 21, 2001. No records were found concerning the last engine overhaul.


The nearest weather reporting facility at the time of the accident was Macon, Georgia. The 1953 surface weather observation was: 800 feet broken, visibility 10 miles, temperature 19 degrees Celsius, dew point temperature 13 degrees Celsius, wind direction 150-degrees at 13 knots gusting to 17 knots, and altimeter reading of 29.81.


Examination of the accident site revealed the airplane was on a 160-degree heading. The wreckage path was 200 feet long.
