N7736R
Beech 95-B55
The twin engine airplane was destroyed on impact with level terrain while executing a missed approach. During a VOR-A approach, the pilot descended 400 feet below the minimum descent altitude and the air traffic controller advised him to check altitude. After declaring a missed approach, ATC issued, and the pilot acknowledged, two vectors, after which radar and radio contact were lost. At one point, the pilot is advised and acknowledged that the runway visual range at a nearby airport is 3,000 feet. The destination airport had an overcast ceiling of 300 feet agl and 1-1/2 mile visibility about 20 minutes before the accident, and a 100 foot overcast ceiling and 1/2 mile visibility about 20 minutes after the accident. Radar data records the aircraft at an altitude of 2,100 feet msl and 4 seconds later records the altitude as 1,600 feet msl. The pilot received his multiengine airplane rating 2 months prior to the accident and had logged 25 hours in multiengine airplanes, 23 hours in the accident airplane, 11.4 hours in the accident airplane as pilot-in-command, and 7.8 hours simulated instrument time in the accident airplane. No anomalies were found with respect to the aircraft that could be associated with a preexisting condition.
HISTORY OF FLIGHT On February 24, 2000, at 1103 central standard time, a Beech 95-B55, N7736R, piloted by an instrument rated commercial pilot, was destroyed when it impacted level terrain near Moorhead, Minnesota. The 14 CFR Part 91 business flight was operating on an instrument flight rules (IFR) flight plan. Instrument meteorological conditions prevailed at the time of the accident. The pilot and the two passengers were fatally injured. The flight originated from the Boone Municipal Airport, Boone, Iowa, at 0910, and was en route to the Moorhead Municipal Airport (JKJ), Moorhead, Minnesota. The pilot was in contact with air traffic control (ATC) during the flight to JKJ. The pilot requested and was subsequently cleared for the VOR-A approach into JKJ. The pilot then advised ATC that he would be executing the missed approach. ATC issued the pilot vectors for the ILS 17 approach at the Hector International Airport (FAR), Fargo, North Dakota. After the pilot had acknowledged the first two vectors issued, radar and radio contact were lost. The following is a summary of communications between ATC and the pilot of N7736R. All times listed are central standard time. The full transcript of these communications is appended to this report. "N7736R" denotes transmissions made by the accident aircraft. "ER" denotes transmissions made by the Fargo Air Traffic Control Tower Approach Control, East Radar position. 1042:12 N7736R fargo approach baron seven seven three six romeo's with ya level at six 1042:17 ER baron seven seven three six romeo fargo approach proceed direct to the v o r expect vectors for the v o r alpha approach at the moorhead airport maintain six thousand fargo altimeter two niner eight seven 1042:27 N7736R two niner eight seven and direct the v o r thanks 1042:49 N7736R is there anybody ah shot the v o r approach into moorhead 1042:53 ER i've had nobody only into fargo 1042:56 N7736R okay doke thanks 1043:00 ER and at fargo we're showing overcast ceilings three hundred one mile visibility 1043:06 N7736R okay what are you landing on 1043:08 ER runway one seven 1043:10 N7736R okay thanks 1043:12 ER winds are currently one three zero at eight 1043:16 N7736R (unintelligible) 1047:04 N7736R do you mind if three six romeo goes a little bit west of the v o r and ah intersects and comes on in 1047:13 ER baron three six romeo that's fine say heading 1047:16 N7736R ah three zero zero 1047:19 ER baron three six romeo roger heading three zero zero vectors for the v o r alpha approach descend and maintain three thousand one hundred and just to let you know the r v r at fargo is down to three thousand 1047:31 N7736R okay thanks 1047:34 N7736R and that was down to thirty one hundred right 1047:37 ER baron three six romeo affirmative 1049:24 ER baron three six romeo turn right heading three two five 1049:28 N7736R right three two five 1050:49 ER baron three six romeo turn right heading three five zero descend and maintain two thousand seven hundred 1050:54 N7736R three five zero down to twenty seven thanks 1052:04 ER baron three six romeo six miles from the v o r turn right heading zero three zero maintain two thousand seven hundred until established on a published portion of the approach cleared v o r alpha approach at moorhead airport 1052:15 N7736R three six romeo ah zero three zero cleared for the approach thanks 1055:41 ER baron three six romeo radar service terminated frequency change approved report cancellation of your i f r with me in the air or princeton flight service on the ground 1055:50 N7736R three six romeo will do and i don't know that we're going to get in 1055:54 ER bonanza three six romeo roger check your altitude 1055:59 N7736R yeah ah three six romeo we're heading back up missed approach 1056:03 ER bonanza three six romeo roger climb and maintain four thousand fly heading zero four zero 1056:11 N7736R heading zero four zero thanks 1056:16 ER baron three six romeo continue the right turn heading zero niner zero vector around the antenna 1056:45 ER baron three six romeo heading zero niner zero vectors i 1 s runway one seven final approach course maintain four thousand 1056:55 N7736R three six romeo 1056:58 ER baron three six romeo did you want to try for the i l s at fargo 1057:16 ER baron three six romeo approach 1057:32 ER baron seven seven three six romeo fargo No further radio transmission was received from N7736R. Radar data for the accident aircraft from 10:52:25 to 10:57:40 cst was plotted on the approach plate for the VOR-A approach at JKJ. This plot and the certified radar data are appended to this report.

METEOROLOGICAL INFORMATION According to a report issued to the investigator in-charge by the Fargo Air Traffic Control Tower (ATCT), the pilot contacted the Fort Dodge, Iowa Automated Flight Service Station (AFSS) by telephone on 4 separate occasions on the date of the accident. During one of the telephone calls, at 0733, the pilot received a standard preflight pilot brief and filed an IFR flight plan for a flight from Boone, Iowa (BNW) to Moorhead, Minnesota (JKJ). At 1039, the automated weather observing system (AWOS) located at JKJ, approximately 6 miles and 60 degrees magnetic from the accident site, was reporting: wind 120 degrees magnetic at 4 knots (kt); visibility 1 1/2 statute miles (sm); fog; overcast ceiling at 300 feet above ground level (agl); temperature 37 degrees F; dewpoint 37 degrees F; altimeter setting 29.85 inches of mercury (inHg). At 1117, the AWOS at JKJ reported: wind 130 degrees magnetic at 8 kt; visibility 1/4 sm; fog; overcast ceiling at 100 feet agl; temperature 37 degrees F; altimeter setting 29.85 inHg. The dewpoint for the 1117 report was blank. At 1053, the Fargo, North Dakota AWOS, located 9 miles and 346 degrees magnetic from the accident site, was reporting: wind 150 degrees magnetic at 6 knots; visibility 1/2 sm; mist; overcast ceiling at 100 feet agl; temperature 40 degrees F; dewpoint 37 degrees F; altimeter setting 29.86 inHg. At 1106, the Fargo, North Dakota AWOS was reporting: wind 150 degrees magnetic at 7 knots; visibility 1/2 sm; mist; fog; overcast ceiling at 100 feet agl; temperature 40 degrees F; dewpoint 37 degrees F; altimeter setting 29.86 inHg. WRECKAGE AND IMPACT INFORMATION The aircraft impacted a level open farm field about 6 miles southwest of the Moorhead Municipal Airport, Moorhead, Minnesota. The wreckage was distributed in a fan shaped pattern extending about 350 feet on a northerly heading. Control system continuity was verified at the tail cone. Due to the extent of the damage to the airframe, control system continuity to the cockpit could not be verified. Aileron system continuity could not be verified due to the extent of damage. All control cable breaks examined exhibited a "horsehaired" appearance consistent with overload failure. The left elevator trim tab actuator showed a tab neutral position. The right elevator trim tab actuator showed a 4-degree tab down position. The rudder trim tab actuator showed an off scale tab left position. The aileron trim tab actuator, located in the left wing, showed a 6.5-degree tab up position. The wing flaps and landing gear were determined to be in the up positions. Both fuel selector valves were determined to be set for the main fuel tanks. Both fuel selector valves were found to contain a bluish colored fuel consistent with aviation gasoline. A bluish colored liquid consistent with aviation gasoline was found in one engine gascolator. No anomalies were detected with respect to the airframe that could be associated with a preexisting condition. The left engine case was shattered. The top and bottom portions of the case were separated. The crankshaft was separated aft of the number 6 connecting rod journal. The fuel pump was the only accessory that remained attached to the engine. The oil screen was examined and no anomalies were noted. The fuel pump rotated freely and the fuel pump drive was intact. The number 1, 2, and 4 cylinder bottom spark plugs were removed and no anomalies were detected. The right engine accessories were separated from the engine with the exception of the fuel pump and propeller governor. The number 1 and 5 cylinder heads were partially separated from the cylinder. The right side cylinders were found intact. The engine oil sump was destroyed and the front of the case was shattered. The oil screen was examined and no anomalies were noted. The fuel pump rotated freely and the fuel pump drive was intact. The number 1, 2, 4, 5, and 6 cylinder upper spark plugs were removed and no anomalies were detected. Both vacuum pumps were located and disassembled. The vacuum pump drives were found intact and no anomalies were detected with respect to the vacuum pumps. The vacuum system hoses were destroyed. The aircraft electric turn coordinator was disassembled and the gyro was found to have evidence of rotational scoring. MEDICAL AND PATHOLOGICAL INFORMATION An autopsy of the pilot was performed at the Dakota Heartland Health System, Fargo, North Dakota. A forensic toxicology was performed by the Federal Aviation Administration. The results were negative for drugs and ethanol. ADDITIONAL INFORMATION Parties to the investigation were: Raytheon Aircraft Company, Wichita, Kansas; Teledyne Continental Motors, Mobile, Alabama; National Air Traffic Controllers Association, Washington, DC; Federal Aviation Administration Flight Standards District Office, Minneapolis, Minnesota. The wreckage was released to a representative of the Moorhead Municipal Airport on February 26, 2000. The aircraft logbooks were released to a representative of the insurance company on October 18, 2000.
the pilot's failure to maintain aircraft control during the missed approach. Factors to the accident were, the pilot's improper decision to attempt the approach in weather conditions below the approach/landing minimums, the weather, the pilot's lack of multiengine instrument experience, and spatial disorientation by the pilot.
