Probable cause

The pilot's failure follow the published instrument approach procedure. A factor in the accident was the low cloud ceiling.

Analysis

While executing a non-precision approach, the airplane impacted a tower located about 2.6 miles northwest of the airport. A witness, who recorded the condition of the tower lighting daily, stated that the illumination of the top light on the tower, on the day of the accident, could not be determined due to fog. Examination of the wreckage revealed that the airplanes heading indicator bug was found selected to 075 degrees. The number one navigational OMNI head OBS was selected to 055 degrees. The approach procedure flight track, as depicted on the approach chart, was 076 degrees. A plot was drawn from the IAF to the tower. The distance from the VOR to the tower was about 8.6 statute miles, on a course of about 050 degrees true.

Factual narrative

History of flight

On October 4, 1999, about 1750 Eastern Daylight Time, a Cessna 182R, N121BG, was destroyed during a collision with a communications tower near Killingworth, Connecticut. The certificated commercial pilot was fatally injured. Instrument meteorological conditions prevailed, and a instrument flight rules (IFR) flight plan was filed for the personal flight that originated at the Igor I. Sikorsky Memorial Airport (BDR), Bridgeport, Connecticut, conducted under 14 CFR Part 91.

During an interview, the owner of the accident airplane stated that he flew the airplane to Republic Airport (FRG), Farmingdale, New York, on the morning of October 4, 1999, with the accident pilot. Upon arrival at FRG, the owner exited the airplane and the accident pilot remarked that he was going to fly the airplane to BDR and "shoot" an approach before returning to the Chester Airport (3B9), Chester, Connecticut.

The accident pilot proceeded to BDR, landed, and picked up a passenger. The accident pilot and passenger conducted several instrument approaches at BDR, before landing about 1630. The passenger exited the airplane and the accident pilot walked to the Flight Service Station (FSS,)located at BDR, to receive a current weather briefing and file an IFR flight plan to 3B9. About 1721, the airplane departed BDR and proceeded to 3B9.

According to Air Traffic Control (ATC) personnel, at 1724, the airplane was instructed to climb and maintain 3,000 feet, and proceed direct to the Madison (MAD) VOR.

When the accident pilot arrived in the area of 3B9, a second Cessna was executing the VOR approach to the airport. At 1728, the second Cessna's pilot radioed the controller and stated that he was "missed approach" at 3B9. The controller queried the second Cessna pilot about why he conducted a missed approach, which the second Cessna pilot replied, "we couldn't see a whole lot there," "low ceilings." The second Cessna proceeded to the Griswold Airport, Madison, Connecticut, executed the VOR A approach, and the pilot advised "landing assured" at 1743.

The accident pilot was then issued a clearance to execute the VOR approach to 3B9, at 1743. The pilot acknowledged the clearance. The controller then terminated radar service, and approved a frequency change. At 1745 the controller also instructed the accident pilot to report canceling his IFR clearance in the air or on the ground with the FSS. At 1746, the accident pilot responded "one bravo gulf uh ok we'll cancel with you if possible." There were no further transmissions from the accident pilot.

The operator of the communications tower received a notification of interrupted service on several broadcast stations, and dispatched a technician to the tower. When the technician arrived at the tower he noticed a gauge on the ground and determined that it was from an airplane. The technician then discovered several other pieces of airplane wreckage and called the local authorities.

The accident occurred during the hours of daylight about 41 degrees, 23 minutes north latitude, and 72 degrees, 33 minutes west longitude.

Personnel information

The pilot held a commercial pilot certificate with ratings for single and multi engine land, instrument airplane. He also held a flight instructor certificate for single engine and multi engine land, instrument airplane.

The pilot's most recent Federal Aviation Administration (FAA) first class medical certificate was issued on September 3, 1999.

Review of the pilot's logbook revealed that he had accumulated about 751 hours of total flight experience. The pilot also accumulated about 18 hours in the accident airplane since July 16, 1999, and had logged about 17 hours of flight experience in actual instrument conditions.

The logbook also revealed that the pilot had also executed the VOR approach to 3B9 a total of three times, once in June 1998 and twice in August 1999.

Aerodrome information

The Chester Airport was located about 2.6 miles southeast of the 370-foot antenna. The airport field elevation was 416 feet MSL, and the recommended traffic pattern altitude was 1,400 feet MSL. The standard traffic pattern for the airport was left-hand traffic. Runway 35/17 was the only lighted runway, and there was no visual glideslope indicator available for either runway.

Wreckage and impact information

The airplane wreckage was examined at the accident site on October 5, 1999, and all major components of the airplane were accounted for at the scene. The main fuselage and engine came to rest nose down, at a ground elevation of about 450 feet MSL, about 850 feet southeast of the tower. Flight control continuity was confirmed from the tail surfaces to the cockpit area. The control cables to the wing sections were found broken in the main fuselage. The cable breaks were consistent with stress overload. The flap actuator jackscrew was measured and confirmed the flaps were in the retracted position. Further control continuity was not confirmed due to impact damage.

The left wing was separated from the fuselage. The inboard section of the wing was located about 100 feet north of the tower, and the flap was still attached. The wingtip, and about a 3-foot section of the wing, was located about 75 feet east of the tower.

The right wing was also separated from the fuselage. An outboard section of the wing, about 6 feet in length, was located about 80 feet north of the tower. The wing section was damaged along the leading edge and displayed orange paint transfer that was similar to the type of paint applied to the tower. The inboard section of the wing was located about 75 feet southeast of the tower, and displayed damage to the leading edge, with orange paint transfer. A section of the wingtip, about 4 feet in length, was located about 45 feet northeast of the tower, and had rearward tears, with orange paint transfer along the separation point. A center section piece of the leading edge was located about 25 feet from the tower, alongside a dirt road, and it displayed severe inward crushing with orange paint transfer.

The right main wheel, tire, and wheel pant assembly was located about 5 feet from the immediate base of the tower.

The engine remained attached to the airframe, and was removed at the accident site for examination. Due to the impact damage to the number 5 and number 1 cylinders, the engine could not be rotated by hand. The oil cooler was destroyed. The vacuum pump was detached from the accessory case, and inspected with no abnormalities noted.

The fuel selector was positioned to the left fuel tank. The carburetor was removed from the engine, and inspected. Fuel was present in the bowl of the carburetor. The engine primer was in and locked. The throttle, propeller control, and mixture control were found in the full forward position.

The left magneto received impact damage, and was separated from the accessory case. The right magneto was found attached to the accessory gear case, and was removed for testing. Both magnetos, when rotated by hand, produced spark on all towers. All spark plugs except the number 5 bottom spark plug were removed; their electrodes were intact and light gray in color. The propeller was found detached from the engine at the hub assembly, lying next to the main fuselage. Both propeller blades exhibited slight rearward bending and chordwise scratches. One propeller blade had three distinct gouges that curled rearward on the leading edge tip. The second propeller blade was damaged along the leading edge from the tip, to a point 14 inches inward.

The airplanes heading indicator bug was found selected to 075 degrees. The number one navigational OMNI head OBS was selected to 055 degrees, with course deviation indicator centered.
