NTSB Factual Report

HISTORY OF FLIGHT

On September 10, 2009, about 1415 eastern daylight time, a Hawker Beechcraft Corporation A36, N888WD, registered to a private individual, collided with trees then terrain in a residential area near Flat Rock, North Carolina. Instrument meteorological conditions prevailed at the time and no flight plan was filed for the 14 Code of Federal Regulations (CFR) Part 91 personal, local flight, from Asheville Regional Airport (AVL), Asheville, North Carolina. The airplane sustained substantial damage and the private pilot, the sole occupant, was killed. The flight originated from AVL about 1403.

According to a transcription of communications with AVL Air Traffic Control Tower ATCT), the pilot established contact with the local control position and advised the controller that he had automated terminal information service (ATIS) victor, with intention of flying locally and to execute, “…some approaches….” The controller questioned the pilot as to what type of approaches, to which he replied that he was not interested in, “…doing any ILS approaches….” He also advised the controller that he wanted to perform landings and fly towards Hendersonville, North Carolina, then return to AVL. The controller cleared the pilot to taxi to runway 34, and confirmed that ATIS information victor was current. The controller then questioned the pilot to verify his flight intentions and he replied that after takeoff he intended to fly towards Hendersonville and fly around there for approximately 10 to 15 minutes, then return to AVL and land. The controller provided the pilot with departure instructions including the departure frequency (124.65 MHz) and transponder code (0210). The flight was cleared for takeoff about 1403, and the pilot was instructed to fly left pattern at or below 3,600 feet and advised the wind was calm. The pilot initially responded acknowledging the altitude but then questioned the controller if he could fly at 3,000 feet. The controller approved the pilot’s request to fly at or below 3,600 feet. The pilot then advised the controller that he intended on extending the downwind leg, would be proceeding towards Hendersonville, and the flight was departing the traffic pattern. The controller twice provided a traffic alert to the pilot, and after the second alert the pilot responded that the traffic was not in sight.

Air Traffic Control communications were transferred to the AVL Approach Control Radar East position, which the pilot acknowledged. The transcription of communications with AVL ATCT further indicates at about 1407, the pilot contacted the AVL Approach Control Radar East position controller and advised that he was at 3,100 feet. The flight was radar identified and the pilot was instructed to maintain VFR and to turn left heading 090 degrees for a vector across final for Hendersonville. The pilot acknowledged the heading, and about 1 minute 11 seconds later the approach controller advised the pilot to resume his own navigation on course towards Hendersonville and to report that airport in sight. The pilot responded that he was flying around the city and was going to, “…stay under these clouds if I can”; the controller did not reply. About 1 minute 5 seconds later the pilot contacted the AVL Approach Control Radar East position and advised the controller that he was ready to return to AVL. The controller advised the pilot to fly heading 150 degrees for a vector for landing sequence, which he read back the heading. The Safety Board ATC Factual Report which contains a plot of radar targets reflects the airplane flying in a southeasterly direction consistent with the vector by the controller.

The transcription of communications with AVL ATCT further indicates that controller then instructed the pilot to fly heading 250, which was consistent with the heading depicted in the radar plot contained in the ATC Factual Report. At 1413:11, the transcription of communications indicates the controller instructed the pilot to, “…turn right heading 340…” and to advise when AVL was in sight. The pilot acknowledged the vector by reading back 340 but did not report the airport in sight. The radar plot contained in the Safety Board ATC Factual Report reflects that about the time the controller instructed the pilot to fly heading 340 degrees, the airplane was flying at 3,000 feet mean sea level, and was flying in a northwesterly direction. The radar plot also reflects that for the last 5 radar returns the airplane turned slightly to the left. The last radar return at 1414:15, indicates the airplane was at 3,100 feet msl, and located at 35 degrees 15.224 minutes North latitude and 082 degrees 27.7188 minutes West longitude.

A controller turnover briefing occurred shortly after the pilot acknowledged the 340 degree heading. The transcription of communications indicates that during the controller turnover briefing, the incoming controller was advised that runway 34 was the active runway with ILS approaches being conducted. The incoming controller was advised that the pilot was advised to fly heading 340 degrees and to report AVL in sight. About 1 minute 8 seconds after the start of the turnover briefing, the new controller questioned on the frequency whether the pilot was capable of tracking the localizer, and also asked him to say the airplane’s current heading; the pilot did not respond to either question. The controller then enlisted the aid of the pilot of another airplane to attempt to communicate with the accident pilot but he did not respond. At 1416:11, the controller advised the pilot that radar contact was lost about a mile west of the broad river radio beacon, or ten miles south of AVL. The controller attempted to communicate with the pilot on the guard frequency (121.5 MHz) but there also was no reply. Personnel of a fixed base operator at Hendersonville were contacted by the AVL ATCT to determine if the airplane had landed there. The individual reported the airplane was not on their ramp.

An individual who was outside of his residence which was approximately 729 feet east-northeast from the accident site reported hearing a very loud constant engine sound with no variations in rpm which lasted for approximately 4 seconds. He then heard a loud boom type sound and called 911. He reported that at the time of the accident there was fog in the area.

The Fire Chief from the Blue Ridge Fire and Rescue who responded to the scene also reported fog.

The pilot, age 65 held a private pilot certificate with airplane single engine land, and instrument airplane ratings issued February 17, 1977, and held a third class medical certificate with a limitation to have available glasses for near vision issued April 30, 2008.

Review of his third and fourth pilot logbooks which contains entries from April 12, 1992, to the last complete entry in the fourth logbook (October 2008) revealed he logged a total flight time of approximately 2,220 hours. His last logged simulated instrument flight consisting of 1.3 hours occurred on April 29, 2008, which was the date of his last flight review in accordance with 14 CFR Part 61.56(a). His last logged actual instrument flight consisting of 6/10 of an hour occurred in October 2008.

AIRCRAFT INFORMATION

The airplane was manufactured in March 1996 by Beech Aircraft Corporation as model A36, and was designated serial number E-3004. It was powered by a 300 horsepower Teledyne Continental Motors IO-550-B engine and equipped with a McCauley D3A32C409-C three-bladed constant speed propeller.

The airplane was equipped with a Honeywell (formerly King Radio Corporation) KFC 150 series two-axis (pitch and roll) autopilot control system. The system incorporates electric pitch trim which provides autotrim during autopilot operation, and manual electric pitch trim. Trim faults are visually and orally annunciated.

Review of the maintenance records revealed the last recorded annual inspection was signed off as being completed on July 13, 2009. The airplane hour meter reading at that time was recorded to be 1,239.4 hours; the hour meter reading at the time of the accident was 1241.4. The last test of the altimeter, altitude reporting, static system, and transponder were recorded as being completed on July 27, 2009.

METEOROLOGICAL INFORMATION

AIRPORT INFORMATION

The Asheville Airport is a combined terminal radar approach control (TRACON) and air traffic control tower (ATCT) FAA level 6 facility. The TRACON was comprised of two radar positions (radar east and radar west), and the flight data position which was located between the two radar positions.

The AVL airport has a single runway designated 16/34, which is 8,001 feet long by 150 feet wide. The AVL airport ATC facility is open from 0630 to 2300 daily. The Asheville airport is located in a valley surrounded by mountainous terrain and numerous minimum vectoring altitude (MVA) areas. With the exception of the approach corridors for runways 16/34, the MVA within Asheville’s approximately 40 mile diameter terminal area, was 4,200 feet and the highest was 8,200 feet. Field elevation was 2,165 feet.

Runway 34 is served by ILS, Localizer, or RNAV approaches. The localizer frequency is 110.5 MHz. The minimum altitude to maintain until glide slope intercept is 4,400 feet mean sea level (msl), and the altitude at the final approach fix is 3,700 feet msl. Runway 34 touchdown zone elevation is 2,140 feet msl.

The AVL Daily Record of Facility Operation Log for the accident date indicates no remarks related to the ILS components of runway 34.

WRECKAGE AND IMPACT INFORMATION

The accident site was located at 35 degrees 15.274 minutes North latitude and 082 degrees 27.767 minutes West longitude, or approximately 11 nautical miles and 166 degrees from the approach end of runway 34, and approximately 388 feet and 322 degrees from the last radar target. The airplane crashed in a wooded area located in a residential area. Debris consisting of the right main landing gear, inboard section of the right flap, and section of rudder were located along an energy path oriented on a magnetic heading of approximately 344 degrees. The main wreckage consisting of the fuselage came to rest upright on a magnetic heading of 320 degrees, approximately 137 feet from the first observed tree contact location. Damage to trees consisting of cut tree trunks and limbs with 45 degree cuts were noted along the energy path.

Further examination of the accident site revealed the fuselage impacted the ground of upsloping terrain. The elevation at the accident site as determined by a handheld global positioning system (GPS) receiver was 2,809 feet msl.

Examination of the wreckage revealed both wings, the horizontal and vertical stabilizers were separated but found in close proximity to the main wreckage. The left wing was fragmented in two pieces while the right wing was fragmented in three pieces. There was no evidence of a pre or post impact fire to any portion of the airplane or airplane components. The propeller was separated from the engine and found upslope from the main wreckage. Examination of the flight control cables revealed no evidence of preimpact failure or malfunction. The flaps were retracted as evidenced by the positions of the left and right flap actuators.

Examination of the cockpit revealed an Insight graphic engine monitor was installed in co-pilot’s side of instrument panel; the faceplate was separated but located. The fuel flow gauge indicated in the green arc, while the cylinder head temperature indicated just below the green arc. The oil temperature needle was separated and the oil pressure was indicating 20 psi, which was just below the yellow arc. The airspeed indicator needle was at 115 knots; the needle was noted to move. The vertical speed indicator was indicating 700 feet-per-minute climb, and the vacuum gauge was indicating off scale low. Examination of the faceplate of the vacuum gauge using a 15 power eye loop revealed no needle impression. The pitch trim indication was approximately 9 degrees airplane nose-up. The graphic engine monitor and altimeter were retained for further examination.

Further examination of the cockpit revealed the throttle, propeller, and mixture controls were full forward, and the cowl flaps were closed. The landing gear selector was in the down position which correlated with the position of the landing gear actuator. Inspection of the avionics circuit breaker panel revealed the TRIM circuit breaker did not appear to be tripped. The VHF transceivers, directional gyro, flight command indicator, pictoral navigation indicator (HSI), autopilot and flight director computer, and autopilot remote mode annunciator panel were retained for further examination.

Examination of the empennage revealed the left elevator trim tab actuator measured 1.250 inches extended which equates to approximately neutral trim, while the right elevator trim tab actuator was separated and not recovered.

Examination of the engine was performed by a representative of the engine manufacturer with Safety Board oversight. No evidence of preimpact failure or malfunction was noted to the engine and system components. A detailed examination report with accompanying pictures is contained in the public docket for this accident.

Visual inspection of the propeller revealed the propeller spinner exhibited impact damage. One blade marked “A” was loose in the hub, bent aft, and twisted towards low pitch. The blade exhibited leading edge scratches and small nicks. One inch of the blade tip was fractured and not recovered. A second blade marked “B” exhibited s-bending, twisting towards high pitch and leading edge scratches. The third blade marked “C” had about nine inches of the blade tip fractured, was loose in the hub, had a slight forward bend, and was twisted towards low pitch. The blade exhibited leading edge scratches and. A four inch section of propeller blade was recovered from the accident site and found to be twisted with leading edge nicks and dents.

MEDICAL AND PATHOLOGICAL INFORMATION

An autopsy was performed on the pilot on September 11, 2009, by Wake Forest University School of Medicine, Department of Pathology. The autopsy findings included blunt trauma to the head and neck, and the report listed the specific injuries.

Forensic toxicology was performed on specimens of the pilot by the FAA Bioaeronautical Sciences Research Laboratory (CAMI), Oklahoma City, Oklahoma, and also the Office of the Chief Medical Examiner, Chapel Hill, North Carolina. The toxicology report issued by CAMI stated testing for carbon monoxide and cyanide was not performed, no ethanol was detected, and an unquantified amount of Ibuprofen was detected in urine. The toxicology report by the Office of the Chief Medical Examiner indicated the result was negative in the urine specimen for ethanol.

TESTS AND RESEARCH

Due to the mountainous terrain surrounding AVL, the AVL ATCT had designated specific mode 3 transponder subsets that inhibit minimum safe altitude warning (MSAW) processing. That was accomplished to prevent repeated nuisance alarms for aircraft operating VFR and not requesting MSAW processing. The discreet mode 3 subset assigned to AVL for local use were transponder codes 0201 through 0277. Of those transponder codes, 0201 through 0207 were reserved for IFR, SVFR, and VFR aircraft requesting MSAW processing. Transponder codes 0210 thru 0277 were utilized for local VFR aircraft and were MSAW inhibited.

When entering flight data into the automated radar terminal system (ARTS), a controller would select IFR+ on the ARTS keyboard for an IFR, SVFR or VFR aircraft requesting MSAW processing. That would automatically assign the next available

NTSB Probable Cause

The pilot’s attempt to maintain visual flight during instrument meteorological conditions, resulting in controlled flight into mountainous terrain. Contributing to the accident was the pilot’s failure to advise the controller of the weather conditions encountered, and his failure to request minimum safe altitude warning (MSAW) monitoring before departure.
