HISTORY OF FLIGHT

On September 1, 2000, at 2210 central daylight time, a Beech K35, N3076C, piloted by an instrument rated private pilot, was destroyed on impact with trees and terrain on approach to runway 32 at Manitowish Waters Airport (D25), near Manitowish Waters, Wisconsin. The personal flight was operating under 14 CFR Part 91. Instrument meteorological conditions prevailed at the time of the accident. An IFR to VFR conditions on top clearance was requested for the flight. The clearance was issued and was terminated. Of the five people on board, the pilot and one passenger were fatally injured, two passengers sustained serious injuries, and one passenger sustained minor injuries. The flight originated from Austin Straubel International Airport (GRB), near Green Bay, Wisconsin at 2035.

The Green Bay Air Traffic Control Tower's chronological summary of flight listed the following:

[2028]- N3076C requested IFR clearance to VFR conditions on top northwest bound at 6500. N3076C was issued a clearance and told to maintain 3000.

[2030]- N3076C read back the clearance and was issued taxi to runway 6.

[2035]- N3076C called ready for takeoff and was cleared for takeoff to fly heading 360.

[2037]- Tower controller asked N3076C his destination, replied Manitowish Waters. Controller issued clearance limit of Clintonville and was instructed to proceed on course.

[2038]- N3076C was instructed to contact departure control.

[2041]- N3076C was issued climb to 10,000 and he replied he just broke out at 3000 and would climb to 3500. N3076C was questioned if he was canceling his IFR and the reply is not readable.

[2047]- Controller tried to terminate radar service but no reply.

[2048]- N3076C acknowledged radar termination but continued to squawk 0106.

A witness stated:

At or near the time above [2210 to 2220] my wife [and] me were in our bedroom with the windows open. We heard a crash. She asked me if I heard it and I say yes. We heard no aircraft motor noise at any time. We are about 6-800 feet from the center line of the approach path. With the weather as it was one wouldn't expect an airplane. Cars hitting deer and other noises are heard quite often so we weren't [concerned]. I did look out at the road [and] woods and seen no fire so we discounted the noise of the crash.

He further said that the ceiling was low and overcast at the time of the crash.

A relative of the pilot called Green Bay Automated Flight Service Station and reported that the flight had not landed at D25.

On September 2, 2000, at about 0723, a Vilas County Deputy was dispatched to locate an overdue airplane for the Green Bay Flight Service. The deputy's report stated:

Dispatch advised that the airplane was due to land at the Manitowish Waters Airport at 11:00 p. m., where they were not contacted of a confirmed landing. ... Upon my arrival at the main entrance of the airport (approximately 08:20), Vilas Dispatch advised that the Civil Air Patrol had found a believed to be survivor (Josiah) from the missing plane, wandering in a grass covered field area, just south of the paved runway to the airport. ... I was directed to the area where Civil Air Patrol (CAP) was attempting to receive a fixed telemetry signal from the planes emergency transmitter. We were joined a few minutes later by some members of the Manitowish Waters Fire Department, where we spread out and began a woods search in the area which CAP directed the search to begin in. The area of the search was conducted in a heavily wooded area, that was located South East of the main approach to the black-top runway. With-in a few minutes of the ground search, one of the Manitowish Waters Fire Department personnel, yelled out that he had located the plane crash site, and there was some survivors that were in need of medical assistance.

A passenger was seated in the right front seat and she was interviewed in a local hospital after the accident. She stated that she thought the pilot was performing an IFR approach and that it was a normal approach. She said that she saw the runway lights. She stated that she remembers hitting something and the pilot saying, "OH NO, OH NO." She said that the pilot was using the emap GPS. She was asked if anything was wrong with the engine and she stated, "No."

A rear seat passenger was interviewed. He stated that during the flight from GRB to D25, the airplane was flying above clouds. He said that he saw runway lights, heard a rumbling or growling sound, like "RRRRRahRRRRRahRRRRR." He and another rear seat passenger both stated that the pilot said, "It's not working, it's not working." He said that the sound occurred about 300 feet or about a minute prior to hitting.

The front passenger said that she was not aware of the pilot's conversation that the rear seat passengers heard.

MEDICAL AND PATHOLOGICAL INFORMATION

The Milwaukee County Medical Examiner performed an autopsy on the pilot on September 3, 2000.

The FAA Civil Aeromedical Institute prepared a Final Forensic Toxicology Accident Report. The report stated:

0.651 (ug/ml, ug/g) CHLORPHENIRAMINE detected in Liver CHLORPHENIRAMINE detected in Urine CHLORPHENIRAMINE NOT detected in Blood PSEUDOPHEDRINE present in Liver PSEUDOPHEDRINE present in Blood PSEUDOPHEDRINE detected in Urine PHENYLPROPANOLAMINE present in Blood PHENYLPROPANOLAMINE present in Liver PHENYLPROPANOLAMINE detected in Urine DEXTRORPHAN detected in Urine NORDEXTRORPHAN detected in Urine DEXTROMETHORPHAN NOT detected in Blood DEXTRORPHAN NOT detected in Blood 19.301 (ug/ml, ug/g) ACETAMINOPHEN detected in Urine

TESTS AND RESEARCH

The airplane's engine was sent to Textron Lycoming for a test run. The engine driven fuel pump, number two and five intake pipes, right magneto condenser cover, and both ignition harnesses were found damaged. The engine driven fuel pump produced suction and pressure to the touch when the unit was rotated by hand. Slave units were installed for the damaged parts. A starter and ring gear support assembly, front plug for the crankshaft, oil drain plug, vacuum pump pad cover plate and propeller governor pad cover plate were installed for the run. The engine was test run. The engine produced full rated power. The engine was accelerated with throttle slams four times from idle to full throttle. The engine reached full power within two seconds on all four of the throttle accelerations. The engine was found to be able maintain an idle at 627 RPM. (See appended photographs and Lycoming engine test run report.)

ADDITIONAL INFORMATION

The parties to the investigation included the FAA, Raytheon Aircraft Company, and Textron Lycoming.

The aircraft wreckage was released to a representative of the insurance company.

A D25 airport commissioner wrote a letter to the pilot. The letter stated, "We would also like a copy of your aircraft [airworthiness] certificate since you have been observed spraying a [starting] fluid into your aircraft and this presents a safety problem at the airport."

A witness, who worked at a Fixed Base Operator (FBO) that repairs avionics, stated:

I talked with [the pilot] the day before his accident. [The pilot] came into [our] shop with his airplane and wanted a COM-11A & GPS- 100AVD fixed. I told him the COM-11A was not repairable, and the GPS-100AVD needed to be sent to the factory for repair. I did get in his airplane to test his GPS and verify it was inop. [The pilot] left the COM-11A with me but took his GPS-100AVD. I tried to sell him another GPS, but he declined. To my knowledge [the pilot] left our shop without a working Com or a working Nav, unless you count his handheld, which he seemed very proud of! ... My personal experience with [the pilot] is he fixed things only when absolutely necessary."

The airplane's manual was reviewed. Excerpts from its Section IV, Normal Procedures, stated:

PREFLIGHT INSPECTION ... 7. LEFT LANDING GEAR: ... d. Fuel Selector Valve Sump and Auxiliary Fuel Cell Interconnect Line - DRAIN; Cover - SECURE

Excerpts from its Section VIII, Handling, [Service] & [Maintenance], SERVICING, stated:

FUEL DRAINS On the standard fuel system open the three snap-type fuel drains daily to purge any water from the system. Each fuel cell drain is located on the bottom of the wing just outboard of the fuselage. The system low spot drain is at the bottom of the fuel selector valve. The drain is accessible through a door in the fuselage adjacent to the wing. When optional auxiliary fuel system is installed, also open the snap-type fuel drains on the auxiliary tanks, and drain on the auxiliary cell interconnect line at the selector valve.

FUEL STRAINERS ... The strainer at the bottom of the fuel selector valve should also be removed and cleaned with solvent every 100 hours.

A FBO at the Greater Rockford Airport (RFD) stated:

The owner did not perform preflight inspections before departure. Two or three months ago one of our line service technicians reported that one of the fuel caps on the aircraft was held on or at least covered with duct tape.

The mechanic, who performed the airplane's last annual inspection, stated:

At the last annual 11-15-99, he had called me at least a month before and said he had a bad oil leak and that his fuel pump was inop. (later I found out from someone that [the pilot] had been spraying either in the engine to start since he couldn't prime it with the fuel pump inop.) During the annual we removed the fuel pump, sent it out for overhaul, and reinstalled. The oil [leak] was corrected by overhauling both oil coolers and replacing all valve cover gaskets. Previously at the 1998 annual the right aux. and main and left main fuel tanks had water and both main tank fuel drains would not open. We installed new main drain valves and cleaned all fuel screens at that time. When he picked up the plane I asked him if he had been draining the fuel sumps? His reply was yes! I then told him that both main drains were [corroded] shut and I had to replace them. His reply was oh yeh I forgot to tell you about that. I then gave him the lecture about how important it was to drain the tanks, especially since the airplane sets outside all the time. At the 1999 annual I again drained at least a 1/2 to 1 pint of water from the fuel tanks, cleaned all the fuel screens, and again gave the lecture on draining sumps. Sometime in June or July 2000 [the pilot] called me and
