A factors was dark night and clouds. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, descent - uncontrolled - spatial disorientation, pilot in command (cause) - aircraft control - not maintained, pilot in command (cause) - light condition - dark night (contributing factor) - weather condition - clouds (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground - object - tree(s) ## Analysis During a cross-country instrument flight at 5,300 feet the pilot radioed that he was having difficulty maintaining altitude. The air traffic controller reported the lost of radar and radio contact with the airplane at 1853. Local authorities were notified, and launched a ground and air search for the downed airplane. The airplane wreckage was located in a wooded area at 0815 on February 7, 2003. Examination of the wreckage did not reveal any airframe or mechanical malfunctions. According to the Federal Aviation Administration Advisory Circular #60-4A: during periods of low visibility a pilot is particularly vulnerable to spatial disorientation. ## Factual narrative HISTORY OF FLIGHT On February 6, 2003, at 1853 eastern standard time, a Piper PA-24-250, N5587P, registered to and operated by Hartford Holding Corporation, collided with trees while maneuvering in the vicinity of Florence, South Carolina. The positioning flight was operated under the provisions of Title 14 CFR Part 91 with an instrument flight plan filed. Instrument meteorological conditions prevailed at the time of the accident. The airplane was destroyed, and the certificated flight instructor, the certificated flight instructor-rated passenger, and the other passenger received fatal injuries. The flight departed Ormond Beach Municipal Airport, Ormond Beach, Florida, on February 6, 2003 at 1530. The flight was en route to Marlboro County Avent Field in Bennettsville, South Carolina. According to radar data, about 1841, the flight was at 5,300 feet transitioning the airspace of Florence Regional Airport, Florence, South Carolina, and the pilot contacted Florence air traffic control and requested if there was any visual weather conditions to the north. The controller provided the pilot with the weather information he had at the time, which was 600 feet overcast at Fayetteville, North Carolina. The pilot elected to proceed to Fayetteville, North Carolina. The controller cleared the flight direct to Fayetteville, North Carolina, and instructed the pilot to descend to 5,000 feet and join victor airway 56. According to radar data, about 1849, the airplane's altitude was at 800 feet, and the controller instructed the pilot to climb. The controller requested the pilot to identify if he was having problems. The pilot responded that he needed a radar heading and he was at 1,800 feet and climbing. At 1850, the pilot requested to land in the closest "weed field". Air traffic control gave the pilot a heading and the distance of the Florence Regional Airport, and requested a no-gyro approach into Florence Regional. At 1852, the pilot radioed that he was having a hard time maintaining altitude between 2,300. The controller lost radar and radio contact with the airplane at 1853. The local authorities were notified that an airplane had gone down and search parties on the ground and in the air located the wreckage in a wooded area at 0815 on February 7, 2003. PERSONNEL INFORMATION The certified flight instructor was issued a commercial pilot certificate on November 24, 1999, with airplane single and muti-engine land, and instrument ratings. Review of the pilot logbook revealed a total flight time of 716 hours but his flight time in the Piper PA-24-250 was undetermined. The certified flight instructor held a second-class medical certificate dated October 5, 2000, valid when wearing corrective lenses. AIRCRAFT INFORMATION A review of N5587P logbooks revealed that the last recorded altimeter, static, and transponder system checks were completed on May 7, 2002. The last annual inspection was conducted on May 20, 2002. The tachometer time at the annual inspection was 1108.9 and the airframe total time was 2962.5. The airplane was not equipped with a pitot tube heating system. METEOROLOGICAL INFORMATION A review of recorded weather data revealed at 1853 at Florence Regional Airport, Florence, South Carolina, reported conditions were winds 050 at 9 knots, visibility 4 statute miles with light rain, broken clouds at 600 feet above ground level, overcast clouds at 1,500 feet above ground level, temperature 3 degrees Celsius, dew point minus 1 degree Celsius, altimeter 30.12 inches, with remarks that the ceiling was variable between 300 feet to 800 feet above ground level. A review of astronomical data for the location of the accident revealed sunset was 1754 eastern standard time, and the end of civil twilight was 1820 eastern standard time. WRECKAGE AND IMPACT INFORMATION Examination of the accident site revealed the wreckage was 5.9 nautical miles north of the Florence Regional Airport, Florence, South Carolina. The wreckage debris was scattered approximately 100 feet along a 360-degree magnetic heading from a tree freshly broken approximately 50 feet above the ground. Approximately 51 feet from the base of the tree, one propeller blade was found separated and embedded in a two-foot deep, seven-foot long, five-foot wide crater. The powerplant was found separated and resting inverted adjacent to the fuselage. Both wing assemblies displayed crush damage from the leading edge aft. A seven-foot section of the left outboard wing assembly was located approximately 25 feet above the ground in a tree. The empennage aft of the cargo door and the tail assembly were found inverted and resting on top of the wing assembly. Examination of the cabin section of the airframe revealed it was damaged. Examination of the cockpit revealed the flight control cables were separated. The vertical stabilizer section of the airplane was intact with the rudder post separated. The rudder cables were attached to the bellcrank and traced to the cockpit. The stabilator and stabilizer trim cables were separated. Examination of the flight control instruments revealed the directional gyro rotor vanes showed damaged on the circumference. The attitude indicator showed scoring on the circumference of the rotor housing, and the electric turn and bank indicator showed scoring on the rotor. Examination of the left wing assembly revealed accordion crush damage along the leading edge of the wing. The left aileron was separated from the wing assembly and bracken in two places. One aileron cable was attached to the bellcrank and the other broken off of the bellcrank. The left flap assembly was partially detached from the wing and broken in two parts. The left main landing gear was found in the retracted position. Examination of the right wing assembly revealed accordion crush damage along the leading edge of the wing. Both aileron control cables were attached to the bellcrank, and traced to the cockpit section. The right main landing gear was partially extended, and the flap was crush damaged. Examination of the airframe did not reveal any anomalies at the conclusion of the examination. Examination of the engine revealed both case halves were broken, and exposed the crankshaft seal. The propeller flange was bent into the case. The engine driven fuel pump, carburetor, and left magneto were destroyed. Crankshaft rotation was obtained and rear accessory drive gears: vacuum pump, magneto, and tachometer were observed rotating. The engine driven fuel pump actuation arm moved when movement of the crankshaft was facilitated. Compression and piston movement was observed in engine cylinders. Examination of the engine revealed no mechanical malfunctions at the conclusion of the examination. MEDICAL AND PATHOLOGICAL INFORMATION Office of the medical examiner, Darlington County, South Carolina performed the pathological diagnoses of the pilot on February 8, 2003. The cause of death was "blunt force trauma". The Forensic Toxicology Research Section, Federal Aviation Administration, Oklahoma City, Oklahoma performed postmortem toxicology of specimens from the pilot. The results were negative for carbon monoxide, cyanide. 15 (mg/dL, mg/hg) Ethanol was detected in the muscle. 21 (mg/dL, mg/hg) Ethanol was detected in the liver. 15 (mg/dL, mg/hg) Acetaldehyde was detected in the liver. " The ethanol found in this case is from postmortem ethanol formation and not from the ingestion of ethanol." ADDITIONAL INFORMATION The wreckage of the Piper PA-24-250, N5587P was released to an insurance adjuster with United States Aviation Underwriters on March 1, 2004. Review of Federal Aviation Regulation (section 23.1323, subpart F, Airspeed indicating system, part d) states: If certification for instrument flight rules or icing conditions is requested, each airspeed system must have a heated pitot tube or an equivalent means of preventing malfunction due to icing.
