MIA96LA042

Witnesses observed the airplane start a turn towards the north and then to the west over a state road. The airplane then turned towards the east, banked to the right, the nose pitch down, and the airplane crashed. The engine appeared to be running until the airplane collided with the ground. Visual examination of the airframe, engine assembly and accessories revealed no evidence of a precrash failure or malfunction. Continuity of the flight control system was confirmed for pitch and roll. The right rudder cable was attached to the rudder. The left rudder cable was not attached. The attach point and retainer pin were in place; however, the clevis pin safety ring was missing and later found by a recovery crew. Safety Board metallurgical examination of the safety ring revealed features indicative that it was cut.

On December 16, 1995, about 1245 eastern standard time, N102DJ, an Otis King Cobra-B crashed in Gainesville, Florida, while on a 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed for the local flight. The private pilot and pilot rated passenger received fatal injuries and the airplane was substantially damaged. The flight had originated from a small private airstrip about 10 minutes earlier.

Witnesses stated they observed the airplane flying towards the north and to the west in the vicinity of state road 45. The airplane turned towards the east, banked to the right, and the nose pitched down. The engine appeared to be running until the airplane collided with the ground.

The wreckage of N102DJ was located in a pasture behind a residence located at 25010 N. W. 71st Place, Newberry, Florida.

Examination of the crash scene by the FAA revealed the airplane collided with the ground in a nose down attitude. Visual examination of the airframe, engine assembly and accessories revealed no evidence of a precrash failure or malfunction. The engine was not disassembled based on witness statements that the engine was operating until the airplane collided with the ground. Continuity of the flight control system was confirmed for pitch and roll. The left rudder cable was not attached to the rudder. The attach point and retainer pin were in place; however the clevis pin safety ring was missing. The right rudder cable was attached to the rudder.

According to Mr. Phillip A. Power, Air Safety Investigator for Carson Brooks Inc., Atlanta, Georgia, the separated clevis pin safety ring was located by a recovery crew, and forwarded to Beverly Morton, FAA Orlando Flight Standards District Office.

Examination of the separated clevis pin safety ring was conducted by the NTSB materials laboratory. Optical microscope and subsequent scanning electron microscope examinations revealed an indentation at the inside diameter surface of the ring adjacent to one of the separated ends. A small portion of the ring in the area located between the indentation and separation was squeezed out forming a shear lip. These features are indicative that the ring was cut. For additional information see NTSB Metallurgist's Factual Report No. 96-100.

Post-mortem examination of the private pilot who was removed from the left seat was conducted by Dr. William F. Hamilton Medical Examiner's Office, District 8, Gainesville, Florida, on December 17, 1995. The cause of death was multiple blunt traumatic injuries. Post-mortem toxicology studies of specimens obtained from the pilot was performed by the Forensic Toxicology Research Section, Federal Aviation Administration, Oklahoma City, Oklahoma. These studies were negative for basic, acidic, and neutral drugs. Azacyclonol was detected in the urine, lung and liver fluid.

Examination of the pilot-rated passenger who was removed from the right seat was conducted on December 17, 1995. The cause of death was multiple blunt traumatic injuries. Post-mortem toxicology studies of specimens obtained from the pilot rated passenger was performed by the Forensic Toxicology Research Section, Federal Aviation Administration, Oklahoma City, Oklahoma. These studies were negative for acidic, basic, and neutral drugs. Tetrahydrocannabinol carboxylic acid (marihuana), 0.183 ug/ml was detected in the urine. 0.014 ug/ml was detected in the blood. 0.003 ug/ml tetrahydrocannabinol was detected in the blood.

Review of the pilot-rated passenger logbook revealed he had recorded as logged 11,289 total flight hours. The pilot's last recorded flight was August 18, 1994. No flights were recorded as logged in N102DJ.

The components retained by the NTSB for further testing was released to Detective Legran Hewitt, Alachua County Sheriff's Office, Gainesville, Florida, on June 3, 1996.
