Jacksonville-Executive at Craig

While on final approach to San Angelo-Mathis Field, the single engine airplane entered a rapid descent with a rate of 5,058 feet per minute then crashed in an open field located about 12 km south of the airport. The airplane was totally destroyed and both occupants were killed.

A commercial pilot with two passengers on a business flight was arriving at the destination airport in a light twin-engine airplane. The air traffic tower controller advised the pilot to follow a slower airplane that was on base leg. The controller subsequently asked the accident pilot if he could reduce his speed,"a little bit." The accident pilot responded that he was slowing down. Less than a minute later, the controller told the accident pilot that he was cleared to land. The accident pilot's last radio transmission was his acknowledgement of the landing clearance. The controller stated that he did not see the accident airplane other than on the radar scope, but did see a plume of smoke on the final approach course for the active runway. Ground witnesses described the airplane as flying slowly with its wings wobbling, turn right, and dive into the ground. The majority of the airplane was consumed by a post crash fire. Inspection of the flight controls and engines disclosed no evidence of any preimpact mechanical problems. Low speed flight reduces the margin between a safe operating speed and an aerodynamic stall. Wing "wobble" at low speeds is often an indicator of an incipient aerodynamic stall. Toxicological samples from the pilot’s blood detected diphenhydramine (a sedating antihistamine commonly known by the trade name Benadryl) at a level consistent with recent use of at least the maximum over-the-counter dose. Diphenhydramine is used over-the-counter for allergies and as a sleep aid, and has been shown to impair the performance of complex cognitive and motor tasks at typical doses. The FAA does not specifically prohibit the use of diphenhydramine by pilots, though Federal Air Regulation 91.17, states, in part: "No crewmember may act, or attempt to act as a crewmember of a civil aircraft...while using any drug that affects the person's faculties in any way contrary to safety..."

The pilot was on an instrument flight from Beaumont, Texas, to Craig Airport, Jacksonville, Florida. According to the pilot's children who were passengers on the airplane, the pilot knew the destination airport was forecast to have fog upon their arrival. Air traffic controllers informed the pilot east of Tallahassee, Florida, the fog at his destination airport would not lift for at least an hour and a half. The pilot was informed the weather at Saint Augustine, Florida, was clear skies with two miles visibility. The pilot informed the controller that he would slow the airplane and continue to Craig. The pilot was subsequently cleared to descend and provided vectors for the ILS Runway 32 approach at Craig. The pilot informed the controller that he had the current automatic terminal information service (ATIS) information. The ATIS for Craig reported an indefinite ceiling with a vertical visibility of 100 feet, and one-quarter of a mile visibility. The weather minimums for the ILS runway 32 approach is a decision height of 241 feet, and one-half mile visibility. The controller informed the pilot to contact Craig Tower. The pilot contacted Craig Tower, and was instructed to report passing the final approach fix. The controller informed the pilot that Jacksonville International Airport had a runway visual range of more than 6,000 feet, and that airplanes were making it in. The controller asked the pilot what his intentions were in the event he made a missed approach. The pilot replied, "I got my brother bringing my mom there into your airfield, so I do not know, what do you think is best, what's closest." The controller replied Jacksonville was closer than Saint Augustine. The pilot informed the controller that he would go to Jacksonville in the event of a missed approach. The pilot was cleared to land, and there was no further radio contact between the pilot and Craig Tower. The airplane was located a short time later in a wooded area, 1.8 miles from the airport. Postaccident examination of the airplane revealed no preimpact mechanical anomalies.

Shortly after leveling off at 14,000 feet the left engine quit. The pilot diverted to Tampa, and 34 minutes later the right engine quit. During the subsequent forced landing the airplane collided with the roof of a covered sidewalk and then trees. Teardown of the left engine revealed that the seal between the exhaust flange and turbocharger was not installed; bolt clamp was finger tight. Heat had melted wiring harness and magneto grounding leads insulation; both 'p' leads were grounded. Pilot stated that after losing the left engine he initiated a left tank to right engine crossfeed, and after 20 minutes of single engine flight in this configuration the right engine quit. Flight manual states to land as soon as possible in case of one engine failure. In addition, it warns that when flying on one engine and cross feeding fuel, absolute coordinated flight must be maintained to prevent unporting of the tank's fuel pickup tube when the tank is not full.

On approach to Jacksonville-Craig Airport, the pilot encountered limited visibility due to night, fog and rain falls. On final, the pilot delayed in initiating a go-around maneuver when the airplane struck the ground and crashed. All eight occupants were slightly injured and the aircraft was damaged beyond repair.

After takeoff from Jacksonville-Executive at Craig Airport, while climbing in marginal weather conditions, the pilot-in-command lost control of the airplane that entered an uncontrolled descent and crashed. All three occupants were killed. The airplane was completing a special flight to Panama City on behalf of the Sheriff's office.
