NTSB Factual Report

HISTORY OF FLIGHT

On February 10, 2002, about 2000 eastern standard time, a Cessna TR182, N5136S, owned by Flying Professionals Inc., and operated by an individual, as a Title 14 CFR Part 91 personal flight, crashed into the water's of the Gulf of Mexico, shortly after takeoff from the Cedar Key Airport, Cedar Key, Florida. Visual meteorological conditions prevailed. No flight plan was filed. The airplane was destroyed. The commercial-rated pilot and three passengers received fatal injuries. The flight was originating at the time, and was en route to Gainesville, Florida.

The airplane had departed Gainesville at 1630, that same day, with four persons on board for the flight to Cedar Key, in order for the occupants to have dinner at a restaurant. The occupants ate dinner at the restaurant and, according to employees at the restaurant; the pilot did not consume alcohol. The occupants returned to the airport by taxi around 1945.

A witness, who was an airport resident and a pilot, stated that he observed the airplane's navigation lights, and heard the engine "...with full power sound," after the airplane departed the runway. He stated "...at an altitude of approximately 150 feet, the airplane made an abrupt left descending turn of about 45 degrees." The witness also pointed out a memorial located at the end of runway 23, which had been placed there after a 1980 aircraft accident, that warned pilots that a horizon "will not be present" during a night takeoff to the west.

An NTSB Air Traffic Control/Operational Factors investigator requested radar data. He reported that he had obtained long-range radar data for February 10-11, 2002, to attempt to identify N5136S after departure from Cedar Key. The Cross City, Florida, radar was the closest site to the accident, and had recorded no targets other than occasional spurious primary reflections during the time period surrounding the accident.

PERSONNEL INFORMATION

The pilot, held an FAA commercial pilot certificate, with airplane single engine land, and airplane instrument, initially issued on August 23, 1999. FAA records showed that the pilot updated his pilot's certificate on October 18, 1999. The pilot held an FAA class 2 medical certificate issued on November 11, 2000, with the limitations "must wear corrective lenses, and possess glasses for near and interim vision." The pilot received a biennial flight review, as required by 14 CFR Part 61, on January 26, 2001.

The pilot's personal flight logbooks were not found. As per entries on the pilot's insurance application, dated November 15, 2001, he had accumulated a total of 1,059.1 total flight hours, all single engine flight hours, and 306.5 hours in this make and model aircraft. There were no records found to indicate the number of instrument or night flight hours that the pilot had accumulated at the time of the accident.

METEOROLOGICAL INFORMATION

The nearest weather station to the accident site was located at the Cedar Key Airport, field elevation 7 feet msl, located about 030 degrees at 1/4 nautical mile from the accident location. The reported weather at 1953 was; winds 230 degrees at 4 knots; visibility 10 miles; sky condition; clear; temperature 16 degrees Celsius; dew point 12 degrees Celsius; altimeter setting 30.16 inches hg.

According to the taxi driver who drove the airplane's occupants to and from the restaurant, when they returned to the airport it was a dark night, with no stars visible, and patches of fog existed over the water. In addition, a pilot at the airport, who saw the airplane before it crashed stated it was a "dark" night, with "light haze" over the water. Recovery personnel reported seeing fog at the crash site about 1 hour after the accident.

WRECKAGE AND IMPACT INFORMATION

The aircraft crashed about 1/4 mile southwest of the departure runway into the water's of the Gulf of Mexico. The accident occurred during the hours of darkness, and the wreckage was located at N29 degrees, 07.476 minutes, W083 degrees, 03.621 minutes. The Levy County Sheriff's Department initially recovered the engine, instrument panel, aft cabin and tailcone. The wings were later recovered and taken by the salvage company to Atlanta, Georgia. The front seats and surrounding structure were not recovered. The rear bench seat was located.

Examination of the airframe parts that were recovered revealed that the Sheriff's Department had to pull the recovered sections of the airplane across the ocean floor about 2 miles to a boat ramp. The sections included the engine, with the nose landing gear and instrument panel attached, the tailcone and empennage, and the rear bench seat, including the lower fuselage structure and gear actuators.

After removal of the airplane from the water it was transported to the Cedar Key Airport. An examination of the fuselage revealed no evidence of fire. The engine cowlings, the cabin overhead and the fuselage belly, from the firewall to the aft doorposts, were not recovered.

The wings were later examined at the salvage dealer's property in Atlanta. The examination revealed that the left and right aileron cables were found attached to the bellcrank. The ailerons had remained attached to the wings. The flaps had also remained attached to the wings, and the flap actuator was found retracted.

Flight controls and aerodynamic surface control cable continuity was not established due to fuselage and cable separations. The rudder cables were confirmed attached at their ends. The elevator cables and push/pull tubes were attached at the elevator bellcrank. The cables were also attached forward at the control tube and arm assemblies.

The empennage remained attached to the tailcone. The horizontal stabilizer and elevator displayed impact damage. The elevator was pushed downward beyond its normal limits during the tow through the water.

The examination of the engine revealed that it was intact and no external discrepancies were observed. The propeller was found attached to the engine crankshaft flange, and the engine was attached to the firewall. Fuel system lines and hoses displayed impact damage. The engine mounts and control cables displayed impact damage and deformation.

Partial disassembly of the engine revealed that residual fuel was found within the engine driven fuel pump and carburetor. A lighted borescope was used to examine the engine top and components. The borescope examination revealed no discrepancies. The engine's crankshaft was rotated, and internal gear and valve train continuity was established. Compression was noted on all six cylinders. The turbo assembly displayed rotational scoring inside of the compressor housing. The oil suction screen and filter were found clean. The spark plugs were gapped properly and exhibited a gray-brown combustion signature. Three types of spark plugs were installed, and according to the engine manufacture, one type, Champion RHB32W plugs were not approved for use in the 0-540 engines. The external and internal examinations of the engine and components did not reveal any discrepancies.

Examination of the propeller revealed that only one propeller blade exhibited torsion and aft bending. Both of the blades rotated freely in the hub. The propeller governor was found secure on the engine case; the governor control arm was found at the high pitch position. The control cable assembly displayed impact damage deformation. The governor was removed and inspected. The inspection revealed that the drive coupling was intact, and rotated. The pumping action of oil was observed. The oil screen was found clean.

Fuel system continuity could not be accomplished due to a lack of recovered components, including sections of lines and the fuel selector valve; however, recovery personnel reported smelling fuel near the crash site. The fuel strainer bowl and screen were found clean. Fuel was found in the engine driven fuel pump and the pump appeared to operate when actuated. The diaphragms showed no discrepancies.

The aircraft was equipped with an engine driven and an electrically driven stand-by vacuum pump. Both pumps rotated and were disassembled. The vanes, rotors and frangible couplings were intact. The check valves in the system allowed a small amount of reverse airflow when blown through.

The instrument panel was recovered with the instruments attached. The attitude indicator was disassembled, the rotor rotated freely and did not exhibit any rotational scoring. The directional gyro was not opened. The instrument panel post lights and the autopilot were found in the "ON" position.

The following documentation of the instruments, switches, avionics and controls, depicts what was observed after the wreckage was removed from the water:

All three landing gear were found in the down position. The gear selector was found in the "down" position. The flap actuator was found retracted, and the flap selector was found at 20 degrees. The elevator trim tab was measured and showed 1.5 inches rod extension, which was equal to 10 degrees tab "up." The emergency locator transmitter (ELT), was found armed, and the ELT battery due date was October 1981.

Flight instrument readings: Airspeed indicator- 0; altimeter- 9,150 feet; altimeter setting- 30.12"; heading indicator- 320 degrees; heading bug- 155 degrees; vertical speed indicator- +/- 2,000 feet; attitude indicator (pitch)- full down; attitude indicator (roll)- left 2 degrees; Nav #1 OBS (omni bearing selector)- 233 degrees; and the Nav #2- destroyed.

The following switches were found in the "ON" position: Master switch, avionics switch #1, navigation lights, rotating beacon, strobe lights, left magneto, right magneto, ignition and alternator/generator.

The following switches were found in the "OFF" position: Landing lights and taxi lights.

The communication and navigational radios were digital and no readings were obtained.

Engine instruments: Tachometer-rpm- 0; Tachometer-hours- 2407.1; manifold pressure- 29 inches; cylinder head temperature- 0; oil pressure- 0; oil temperature- 0; fuel pressure- 0; ammeter- 0; and instrument suction gauge- off scale, on the high side.

The optional, owner installed standby vacuum switch, was found in the "ON" position.

The engine controls were found in the following positions: (at the engine) Throttle- idle; mixture- mid-range; and propeller control- high pitch. The controls in the cockpit showed that the cowl flaps were- open; and the primer- in/locked.

The front seats and seat belts were not recovered. The rear seat was the only seat observed. The seat was intact, but not completely attached to the floor. According to the Levy County Sheriff's Department, the women seated in the rear seats were found wearing their lap belts. The cabin overhead was missing and no evidence of shoulder harnesses was observed. The rear belts had no shoulder harness provisions. According to Cessna's records the aircraft was delivered with front shoulder harnesses and inertia reels.

MEDICAL AND PATHOLOGICAL INFORMATION
