A factor in the accident was the pilot's use of inappropriate medications. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, cruise - spatial disorientation, pilot in command (cause) - weather condition - icing conditions - aircraft control - not maintained, pilot in command (cause) - use of inappropriate medication/drug, pilot in command (contributing factor) - design stress limits of aircraft - exceeded, pilot in command (cause) - Airframe/component/system failure/malfunction, cruise - wing - separation - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis The airplane was cruising at 11,000 feet when the air traffic controller noticed it was over 40 degrees off its assigned heading. The controller contacted the pilot, who said he would correct his heading. The controller then offered him a direct course to his destination, which the pilot accepted. The controller observed the airplane make another "hard left turn," and queried the pilot again, but received no reply. The airplane lost 4,000 feet during a 24-second period, after which, radar contact ceased. Witnesses on the ground saw the airplane descend out of the clouds in a vertical spiral, then saw the left wing depart. The engine was running in an overspeed condition. Toxicological testing of the pilot, a retired medical doctor, revealed the presence of a barbiturate, an antidepressant, an antihistamine sometimes prescribed as a sleep aid, and quinine. ## Factual narrative HISTORY OF FLIGHT On October 5, 2001, at 1440 eastern daylight time, a Cessna 210M, N6053B, was destroyed during an in-flight break-up over Pittsfield, Pennsylvania. The certificated private pilot/owner and the passenger sustained fatal injuries. Visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the flight that originated at Ohio State University Airport (OSU), Columbus, Ohio. The personal flight was destined for Syracuse Hancock International Airport (SYR), Syracuse, New York, and was conducted under 14 CFR Part 91. A review of air traffic control (ATC) voice recordings revealed that the pilot made contact with a Cleveland Center (CLE) controller at 14:34:08. The controller acknowledged the radio call, and issued an altimeter setting to the pilot. He subsequently asked, at 14:37:49, "six zero five three bravo, are you still headed to wellsville, or did they turn you someplace?" The pilot responded, "naw, i just went over... i'm going to wellsville now." The controller then stated, at 14:37:57, "roger, you can go direct to syracuse if you like," which the pilot accepted, and at 14:38:02, stated, "roger that. direct to syracuse." At 14:39:27, the controller asked, "five three bravo, what's your heading now?" However, there was no response. The controller continued attempts to contact the pilot, and consulted other controllers to see if the airplane's radar target was depicted on their consoles. There were no further transmissions from the airplane. A review of radar data from the Cleveland Air Route Traffic Control Center (ARTCC) depicted a radar target with the airplane's assigned transponder code. The target was maintaining a northeasterly heading, and mode C altitude indicated 11,000 feet. The target eventually turned to an easterly direction, then, about 10 miles northeast of the Tidioute VOR, it made a left turn of approximately 90 degrees over a distance of 3/8 of a mile, and duration of 15 seconds. The turn was completed at 1438:29. The target then turned right, back to the north, but again initiated a turn to the left, to a southwesterly heading. At 1439:02, the target was at 10,900 feet. About 24 seconds later, the target had descended to 6,900 feet, where transponder returns were lost. At 1439:38, primary radar returns were received in the vicinity of the accident site, and continued for approximately 90 seconds after the last transponder return. During a telephone interview, the controller stated that the airplane's course between the Tidioute VOR and the Wellsville VOR was 080 degrees, and the airplane was tracking 40 degrees off course, to the east, prompting the question "...did they turn you someplace?" The controller then offered the pilot a direct course to Syracuse, which the pilot accepted. Another "hard left turn" was observed, and the controller queried the pilot again about his heading, but received no response. A couple was walking in the woods near the accident site, when they became aware of the airplane. During a subsequent telephone interview, the first witness said: "... I heard this loud crack. I looked up and I could see the left wing was broken off the airplane, and it was spinning in a counter-clockwise direction." The witness at first thought it was an aerobatic airplane, but then realized the airplane was in distress. He was certain that the left wing departed the airplane, and that the engine was running continuously until ground impact. The second witness stated that her boyfriend called her attention to the airplane. The engine was "really loud", and the engine speed and pitch were so high that she thought it was a "four-runner." According to a third witness, he was inside his home about 1 mile from the crash site when his attention was drawn to the airplane's engine noise. He ran outside and observed the airplane in a spinning, vertical descent. A fourth witness, who lived about one-half mile from the crash site, stated that he was working in the back of his barn when he heard the airplane. He said it sounded "rough, erratic, and choppy", and "had a real high-pitched whine, kind of a scream. After the high-pitched whine, I heard the crash. When I came out of the barn, I could see a piece of metal kind of pin wheeling down." A fifth witness, who was a pilot and an airframe and powerplant mechanic, stated he heard the airplane just prior to the crash. "I heard this hell of a noise. That engine was so far over rpm that it just made a squeal. I didn't see it, and I didn't hear the engine before that. But that engine made such a noise; I mean it was really wound up. You couldn't put a throttle forward far enough to make an engine go like that." The accident occurred during the hours of daylight, approximately 38 degrees, 59 minutes north latitude, and 078 degrees, 38 minutes west longitude. PERSONNEL INFORMATION The pilot held a private pilot certificate with ratings for airplane single engine land and instrument airplane. His most recent third class medical certificate was issued on June 4, 2001. The pilot reported 2,000 hours of flight experience on that date. On an insurance renewal application form dated June 7, 2000, the pilot reported 1,700 hours of total flight experience, and 900 hours in make and model. AIRCRAFT INFORMATION The airplane was on an annual inspection program. The most recent annual inspection was completed on October 2, 2001, at 2,543 aircraft hours. Examination of the airplane's maintenance records revealed that a factory re-manufactured engine was installed on August 17, 2000, at 2,404.2 aircraft hours. METEOROLOGICAL INFORMATION A review of weather data revealed there was an AIRMET issued at 0945, valid until 1600, for occasional moderate rime or mixed icing in clouds and in precipitation between the freezing level and FL200 along the airplane's route of flight. The freezing level was forecast between 7,000 and 11,000 feet. An AIRMET for the same time period was issued for occasional moderate turbulence below 10,000 feet, and was in effect for an area that was also along the airplane's route of flight. At 1450, the weather reported at Jamestown, New York, about 21 miles north of the accident site, was a ceiling of 3,900 feet broken, 4,500 feet overcast, and visibility of 10 miles with wind from 260 degrees at 6 knots. The temperature was 62 degrees F and the dew point was 53 degrees F. The pilot reported to ATC that he was experiencing icing and turbulence. The controllers offered a change in altitude and the pilot initially declined. Later, the pilot requested a climb to 11,000 feet, and the request was approved. The airplane's assigned altitude was 11,000 feet at the time of the accident. WRECKAGE AND IMPACT INFORMATION The airplane was examined at the site on October 6, 2001. All major components were accounted for, but the wreckage was distributed over about 1 mile of heavily wooded terrain. The left wing, left horizontal stabilizer, left elevator, and the right outboard elevator and counterweight were separated from the main wreckage. The main wreckage came to rest at the initial point of ground contact. Tree strikes were noted directly above the wreckage. Angular cut tree limbs were scattered under and around the wreckage. The cockpit, cabin area, fuselage, and empennage were completely destroyed by fire. All cockpit controls and panel instruments were consumed by fire. The center of the wing carry-through spar was exposed and laying on the ground above the outline of the main fuselage. The right wing was essentially intact, with the outboard 5 feet of the leading edge crushed aft in compression. The inboard section of the wing where it attached to the fuselage was destroyed by fire. The engine came to rest inverted, beneath the right wing.
