Analysis

According to a friend of the pilot, when the flight departed there were no apparent airplane problems observed as he watched the airplane fly south for about ten minutes. The flight never arrived at the destination airport. After an alert notice was issued by the Federal Aviation Administration, local law and volunteer groups initiated a search for the missing airplane. On June 17, 1996, at 1800 hours, the airplane wreckage was located in a wooded area two miles north of the destination airport. Examination of the accident site disclosed that aircraft collided with 65 foot tall trees, and wreckage debris was scattered over an area 250 feet long and 45 feet wide. Inspection of the airframe and engine assemblies failed to disclose a mechanical problem. A review of the pilot's medical history disclosed that he had coronary problems, and had been granted a limited class three medical certificate.

Aircraft information

Information on the airplane is contained in this factual report on page 2 under the data field labeled "Aircraft Information."

According to the Federal Aviation Administration medical records, the pilot had undergone a special class three medical issue process for his coronary condition. This process placed a one year limitation on the pilot's medical certificate.

A review of weather data disclosed that conditions favorable for the formation of carburetor ice existed at the time of the accident.

Wreckage and impact information

Examination of the accident site disclosed that aircraft collided with 65 foot tall trees, and wreckage debris was scattered over an area 250 feet long and 45 feet wide. Wreckage debris was orientated on a 068 degree magnetic heading. Examination of the accident site disclosed that there were several freshly broken trees about 225 feet southwest of the main wreckage. Debris from both wing tips was located in the immediate vicinity of this first group of freshly broken trees. Approximately 85 feet northeast of the first group of broken trees, the left wing assembly, and the right horizontal stabilizer with the elevator assembly, were located adjacent to a second group of freshly damaged trees. The rudder assembly was located 135 feet northeast of the first group of freshly broken trees. Additional airframe debris was located in the immediate vicinity of the main wreckage. The main wreckage, that included the fuselage, rested against a tree.

Examination of the main wreckage revealed that the right wing assembly was damaged but remained attached to the airframe. The cockpit area was torn open exposing the interior to ambient conditions. The instrument panel was displaced aft towards the pilot's and front passenger's stations. Further examination of the cockpit area disclosed that the pilot's seat assembly was dislodged from its normally installed position; the pilot's seat assembly was found several feet away from the main wreckage. During the examination of the pilot's seat, it was discovered that one side of the pilot's seat belt was frayed and torn into two sections.

The engine was displaced aft into the firewall, but remain attached to the airframe throughout the crash sequence. The propeller assembly also remained attached to the engine. Examination of the propeller blades disclosed that both blades had sustained some chordwise bending and twisting at the tips. Further examination of the engine assembly revealed that the carburetor bowl was broken. The engine was subsequently removed from the accident site for further examination. The engine examination included the removal of accessory section components for functional evaluations. The examination of the engine assembly and the accessory components failed to disclose a system malfunction or component failure.

Examination of the airframe, that included the flight control system, also failed to disclose a mechanical malfunction.

Medical and pathological information

The autopsy and toxicological examinations on the pilot were never done. According to the Federal Aviation Investigator assigned to this investigation, a verbal request had been made with Shelby County Medical Examiner's Office in Memphis, Tennessee, to conduct an autopsy examination on the pilot, and to collect samples for toxicological examinations. Several days after the agreement, the toxicology sample box was returned to the Flight Standards District Office in Memphis, Tennessee. During the follow-up inquiry about the autopsy, it was learned that the pilot had been funeralized without the completion of the post autopsy or toxicological examination being completed.

Additional information

The airplane wreckage was released to Mr. A.T. Guron (Manager, Arlington Municipal Airport).
