NTSB description

HISTORY OF FLIGHT

On July 12, 1997, at 1308 central daylight time, a Cessna 150F, N8197S was destroyed on impact with the terrain following a departure from controlled flight. The pilot sustained fatal injuries. The 14 CFR Part 91 flight was picking up a banner at the time of the accident at the Gary/Chicago Airport, near Gary, Indiana. Two eyewitnesses reported that the airplane was "slow" during the approach to the banner and during the initial climb after picking up the banner. The local flight was operating in visual meteorological conditions. No flight plan was on file. The flight originated from the same airport about 1255.

The owner/operator of the banner towing business said that the purpose of the flight was to tow a banner reading, "JANNELLE, MARY ME? HOLY COW." The banner was to be towed over Wrigley Field in Chicago, Illinois. He said the pilot had successfully towed banners for this company for about two months prior to the accident. He said that the banner was set up in the grass, on the east side of runway 20. The owner said that the pilot had used this pickup point previously and had successfully towed banners of this size, with this airplane.

Two air traffic controllers working in the Gary/Chicago tower witnesses the accident. They indicated that after departure the airplane remained in the traffic pattern until a lull in the traffic allowed the pickup of the banner. They said that the pickup pass was to the south adjacent to runway 20. They said that there was a small delay because the rope fell off one of the poles and the accident airplane continued to circle until the rope was again placed on the pole.

The local controller said that the, "Aircraft made a normal pickup; however, appeared extremely slow on climb out." He said that he told a fellow controller, "97S better put his nose down and gain some speed." He said that, "Approximately 40 seconds after the pickup the banner came off and 97S appeared to level off, aiming for runway 02, then nosed into the ground approximately 150 feet south of approach end of runway 02."

The ground controller also witnessed the accident and said, "The pickup appeared normal; however, the aircraft appeared to be struggling for airspeed and altitude immediately after pickup. The aircraft proceeded approximately fifteen hundred feet from pickup site and then dropped the banner in the trees southeast of departure end of runway 20. He then leveled out and appeared to be making an attempt to land on runway 02 when it spun to the right and nosed in approximately one hundred feet from the approach end of runway 02."

PERSONNEL INFORMATION

The pilot born February 2, 1936, was the holder of a commercial pilot certificate with an instrument rating. His most recent second class medical was received on May 20, 1997, with the limitation, "Must wear glasses for near and distant vision." No personal logbooks were recovered for the pilot. Information regarding his flying experience was obtained through the Federal Aviation Administration records and an interview with the owner of the banner towing business.

AIRCRAFT INFORMATION

The airplane was a Cessna 150F, N8197S, serial number 15061797. At the time of the accident, the airplane had accumulated a total flight time of 5,052 hours. The most recent annual inspection was conducted on October 4, 1996, at 4,917 hours. At the time of the accident, the engine had accumulated 455 hours since overhaul.

WRECKAGE AND IMPACT INFORMATION

The airplane came to rest upright on an east-northeast heading, about 200 feet southeast of the approach end of runway 2. The nose of the airplane penetrated the surface of the ground and the airplane remained stationary with the tail in the air. Both wings were separated from the fuselage top; however, remained attached to the lift struts and both were in their relative position to the fuselage. The right wing displayed a 45-degree crease from the leading edge aft for about four feet from the wingtip inboard. The left wing displayed fore to aft crushing along the entire leading edge. The engine and firewall were displaced rearward into the cockpit area. The tailcone was bent down and to the left about midway between the baggage area and the leading edge of the horizontal stabilizer. The flaps were found in partial extension. Continuity was found through the aileron, rudder and elevator systems. Fuel remained around the accident site and was leaking from the tanks. There was fuel in the fuel lines and the selector (on/off valve).

The propeller was separated at the crankshaft flange with the flange remaining attached to the propeller. There was bending and twist in both propeller blades. The leading edge of both blades displayed nicks, gouges, and chordwise polishing and scratching.

The engine remained in its relative position; however, was separated from broken engine mounts and the firewall. There was deformation in the firewall consistent with impact between the engine and the firewall. The right mag had separated from the mount and was hanging by the high-tension leads. The carburetor was separated from the mount and was hanging from the accelerator pump shaft. Engine oil had leaked out of the broken oil pan. The oil return lines were in place, but were bent during the impact sequence.

The carburetor was examined and found to contain residual fuel. The spark plugs were removed and found to contain combustion products. All cylinders had thumb compression. During rotation, the left mag sparked at all leads. The engine was rotated through the vacuum pump drive and continuity was established throughout.

MEDICAL AND PATHOLOGICAL INFRMATION

A post-mortem examination of the pilot indicated death was due to blunt trauma. No pre-existent pathology was found to suggest incapacitation. A toxicological examination of specimens from the pilot was negative for the drugs screened.

ADDITIONAL INFORMATION

Parties to the investigation were the Federal Aviation Administration, Flight Standards District Office, South Bend, Indiana; Lycoming Engine Company of Williamsport, Pennsylvania; and Cessna Aircraft Company of Wichita, Kansas.

The wreckage was released to the owner of the airplane on July 14, 1997.
