Commander Aircraft 114TC

Analysis

The airplane impacted terrain during a missed approach at night in instrument meteorological conditions. The pilot had been cleared for the instrument landing system (ILS) runway 13 approach into Hutchinson Municipal Airport. The decision altitude for the approach is 1,724 feet msl (200 feet agl). The pilot reported going missed approach after passing the middle marker at 1,600 feet msl (75 feet agl), based on aircraft radar track data. The missed approach instructions were to climb to 4,000 feet msl on runway heading and contact Wichita approach control. A plot of the radar track data showed the airplane in a climbing left turn. The aircraft's climbing left turn reached a maximum altitude of 2,000 feet msl (460 feet agl) before the airplane entered a descending left turn. The pilot was communicating with Wichita approach control during the left climbing turn. The airplane impacted off the left side of runway 22 on a 334-degree magnetic heading. The airplane impacted left wing first and the total wreckage debris path was approximately 280 feet long. An FAA test aircraft flew the ILS runway 13 approach after the accident and determined the approach was fully operational and tested satisfactory. The pilot held an instrument rating, but was not instrument current as required by federal aviation regulations. The weather at the time of the accident included overcast ceilings at 200 feet agl and visibilities between 1-1/4 and 2 sm. No pre-impact anomalies were found with the airframe or the engine.

Factual Information

HISTORY OF FLIGHT On November 2, 2003, at 1847 central standard time, a Commander Aircraft 114TC, N6107Z, piloted by a private pilot, was destroyed during an in-flight collision with terrain at the Hutchinson Municipal Airport (HUT), Hutchinson, Kansas. Night instrument meteorological conditions (IMC) prevailed at the time of the accident. The business flight was operating under the provisions of 14 Code of Federal Regulations (CFR) Part 91 while on an instrument flight rules (IFR) flight plan. The pilot was fatally injured. The flight departed Wiley Post Airport (PWA), Oklahoma City, Oklahoma, at 1737. According to Federal Aviation Administration (FAA) air traffic control (ATC) transcripts, the pilot had been cleared for the instrument landing system (ILS) approach to runway 13 at HUT. The pilot had flown the approach and subsequently reported going missed approach after passing the middle marker. The following is a summary of the voice communications between the pilot of the accident airplane (N6107Z), Wichita Approach Control (ICT-Approach), and Hutchinson Control Tower (HUT-Tower): At 1814:10 (hhmm:ss), N6107Z contacted ICT-Approach and was told to expect the ILS runway 13 approach into HUT. At 1815:42, ICT-Approach relayed the current weather conditions at HUT to N6107Z: Wind 040 degrees true at 07 knots; 1-1/4 statute mile (sm) visibility with mist; overcast ceiling at 200 feet above ground (agl); temperature 6 degrees Celsius; dew point 6 degrees Celsius; altimeter 30.03 inches-of-mercury. Wind direction was variable between 010 and 080 degrees true. At 1821:45, ICT-Approach cleared N6107Z from 8,000 feet mean sea level (msl) to 5,000 feet msl. At 1824:48, ICT-Approach cleared N6107Z from 5,000 to 4,000 feet msl. At 1827:28, ICT-Approach cleared N6107Z to fly direct to Hutchinson VHF Omni-Directional Range (HUT VOR), and after passing the VOR to fly 310 degrees magnetic. ICT-Approach also told N6107Z to expect vectors for the final approach course. At 1833:31, ICT-Approach issued missed approach instructions to N6107Z. The missed approach instructions were to fly runway heading and climb to maintain 4,000 feet msl. Between 1835:15 and 1839:43, ICT-Approach provided vectors for the final approach course. At 1839:43, ICT-Approach cleared N6107Z to maintain at or above 3,200 feet msl until established inbound on the localizer. ICT-Approach also cleared N6107Z for the ILS runway 13 approach. At 1840:44, N6107Z reported being established inbound on the localizer. ICT-Approach terminated radar service and instructed N6107Z to contact HUT-Tower. At 1840:59, N6107Z reported being outside the final approach fix (SALTT). HUT-Tower cleared N6107Z to land on runway 13 and reported the current surface winds. HUT-Tower also told N6107Z to report either the missed approach or being on the runway. At 1841:58, HUT-Tower told N6107Z the field visibility was 1-1/4 statute miles and there was an overcast ceiling of 200 feet agl. At 1843:34, N6107Z reported being at SALTT and was inbound on the ILS runway 13 final approach. At 1845:49, N6107Z reported missed approach and HUT-Tower told N6107Z to fly runway heading and climb to maintain 4,000 feet msl. At 1846:01, N6107Z acknowledged the missed approach clearance. At 1846:06, HUT-Tower asked N6107Z if he saw any runway lights during the approach. N6107Z replied, "N6107Z right over the runway now, I just got them too late." At 1846:14, HUT-Tower told N6107Z to contact ICT-Approach and N6107Z acknowledged the frequency change. At 1846:33, N6107Z reported being on the missed approach to ICT-Approach. At 1846:39, ICT-Approach asked N6107Z what his intentions were. N6107Z replied, "yeah what's the weather look like in Wichita right now." At 1846:46, ICT-Approach reported, "Wichita was showing two thousand seven hundred overcast, visibility is ten miles, winds are uh zero three zero at eight and the altimeter [setting] is three zero zero zero." There were no additional communications between ATC and N6107Z. Aircraft radar track data was obtained from FAA ATC. The data indicated there was a single aircraft transmitting a discrete beacon code near the accident location at the time of the accident. The aircraft radar track data was plotted on an ILS runway 13 approach chart, and the plotted track traced back along the final approach course. According to the supplied data, the first radar return for the accident aircraft was recorded at 1825:51. The plotted track showed the airplane being vectored on a right downwind for the ILS runway 13 approach. At 1838:10, the airplane turned from a northwesterly downwind to a northeasterly heading. At 1839:22, the airplane began a right turn and was established on the localizer centerline at 1842:11, approximately 2.5 nm from the final approach fix (SALTT). The airplane passed the outer marker at approximately 1843:47, at 2,800 feet msl. The airplane passed the middle marker at approximately 1845:48, at 1,600 feet msl (75 feet agl). The plotted track continued along the runway heading until 1846:24, when the airplane entered a climbing left turn. The aircraft's climbing left turn reached a maximum altitude of 2,000 feet msl (460 feet agl) before the airplane entered a descending left turn. The aircraft's last recorded radar return was at 1847:24, at 1,700 feet msl (160 feet agl).

After the accident, the approach was taken out-of-service until it could be tested. On November 6, 2003, the ILS runway 13 approach was flight tested by the Oklahoma City Flight Inspection Field Office. According to the Flight Inspection Report, the ILS runway 13 approach was fully operational and tested satisfactory. AIRPORT INFORMATION The Hutchinson Municipal Airport (HUT) is located in Hutchinson, Kansas. The airport has three asphalt runways: 13/31 (7,004 feet by 100 feet), runway 4/22 (6,000 feet by 100 feet), and runway 17/35 (4,252 feet by 75 feet). The general airport elevation is listed as 1,543 feet msl. The elevation of the runway 13 threshold is listed as 1,525 feet msl. A medium intensity approach lighting system with runway alignment lights precedes the runway threshold. There were three notices-to-airmen (NOTAMS) listed for runway 13 at the time of the accident: * The pilot-control unit for the runway 13 approach lighting system was out-of-service. * Runway 13 approach lighting system was out-of-service, except for medium intensity. * The runway 13 alignment indicator lights (RAIL) were out-of-service. WRECKAGE AND IMPACT INFORMATION The National Transportation Safety Board's (NTSB) on-scene investigation began on November 03, 2003. A global positioning system (GSP) receiver recorded the position of the main wreckage as 38-degrees 04-minutes 02.6-seconds north latitude, 97-degrees 51-minutes 12.5-seconds west longitude. The main wreckage was located on runway 22, approximately 1,650 feet from the approach end of the runway. The aircraft impacted off the left side of runway 22. There was a wreckage debris path that measured approximately 280 feet long. The heading of the debris path centerline was measured with a compass and was 334 degrees magnetic. The initial impact ground depression contained portions of the left wingtip. The inboard half of the left wing was found approximately 128 feet from the initial impact point. The left cabin entry door was located approximately 146 feet from the initial impact point. The outboard half of the left wing was found approximately 158 feet from the initial impact point. The main wreckage was located approximately 280 feet from the initial impact point, and consisted of the main cabin, the right wing, and empennage. All components of the aircraft were located along the wreckage path and all flight control surfaces remained attached to their respective airframe positions. The left wing was found completely separated from the fuselage. The wing was found broken in two sections, with the separation at approximately midspan. The main wing spar was bent aft approximately 30 degrees at midspan. The left aileron remained attached to the wing and both aileron cables were found attached to the left aileron bellcrank. The aileron actuation push/pull rod was found attached to the aileron bellcrank and the flight control surface. The left flap remained attached to the wing. The left wing fuel tank was ruptured, but residual fuel was noted inside the tank. The right wing remained attached to the fuselage. The outboard quarter of the leading edge was crushed aft to the main spar. The right flap remained attached to the wing. The right aileron remained attached to the wing and both aileron cables were found attached to the right aileron bellcrank. The aileron actuation push/pull rod was found attached to the aileron bellcrank and the flight control surface. The right wing fuel tank was ruptured, but residual fuel was noted inside the tank. Aileron flight control cable continuity could not be established due to extensive damage. All aileron flight control cable separations had fracture features consistent with overload. The wing flap actuator was in the fully retracted position, which is consistent with the wing flaps being fully retracted. The right main landing gear was in the fully extended position. The position of the nose and left main landing gear could not be determined, due to damage. The horizontal stabilizer, elevator, vertical stabilizer, and rudder remained attached to the aft-fuselage. The elevator remained attached to the horizontal stabilizer. Elevator flight control cable continuity was established from the aft bellcrank to the forward cabin. The elevator flight control push-pull tube was continuous from the aft elevator bellcrank to the elevator surface. The elevator control stops were inspected and no evidence of deformation was noted. The rudder remained attached to the vertical stabilizer. Rudder flight control cable continuity was established from the control surface to the forward cabin. The rudder control stops were inspected and no evidence of deformation was noted. The engine was found completely separated from its engine mounts. Engine crankshaft continuity was established by rotating the crankshaft at the propeller flange. Rear accessory section and valve train continuity was established while the engine crankshaft was rotated. There was compression on cylinder numbers one, three, four, and six when the engine crankshaft was rotated. The number two cylinder head was cracked. There was extensive damage to the valve assembly for the number five cylinder. T

Probable Cause and Findings

The pilot's diverted attention during the missed approach which resulted in aircraft control not being maintained. Factors to the accident included the pilot not being current for instrument operations and the low cloud ceiling at night.
