The pilot was conducting a cargo flight in night instrument meteorological conditions, and was cleared for the ILS Runway 6L approach. The pilot reported that he was established on the localizer, and the control tower stated that the touchdown and mid-point "RVR" was 1,800 feet, and the roll-out "RVR" was 1,600 feet. The pilot also was instructed, and acknowledged, to make a right turn off the runway, after landing. There were no further communications from the airplane. The airplane's last radar target was observed at an altitude of 1,200 feet msl, and a ground speed of 130 knots. The airplane impacted trees, and came to rest inverted on airport property, on a bearing of 053 degrees, and a distance of 1/2 mile to the runway. Examination of the airplane did not reveal any pre-impact mechanical failures. A weather observation taken at the airport about the time of the accident included, winds from 140 degrees at 9 knots, 1/8 mile visibility, runway 06L visual range variable between 1,800, and 2,000 feet in fog, vertical visibility 100 feet, and a temperature and dew point 54 degrees F. The airport elevation was 1,009 feet msl. Review of the approach diagram for the ILS Runway 6L approach revealed a decision height of 1,198 feet msl, and an approach minimum of 1,800 feet runway visual range (RVR), or 1/2 mile visibility. The pilot had accumulated about 3,800 hours of total flight experience, which included about 350 hours in the same make and model as the accident airplane, and 250 total hours logged in instrument meteorological conditions.

The airline transport pilot (ATP) stated the airplane was between 200 to 300 feet on initial takeoff climb when the right engine lost power and the airplane yawed to the right. The pilot lowered the nose of the airplane to gain airspeed, pulled the right power lever rearward and nothing happened. The pilot did not feather the right propeller and started moving switches in the vicinity of the boost pump switches. The ATP passenger stated, he did not think the left engine was producing full power. He scanned the instruments with his eyes looking at the manifold pressure gauges. "One needle was at zero and the other was at 25-inches. The manifold pressure should have been 39-inches of manifold pressure. The ATP passenger observed trees to their front and thought the pilot was trying to make a forced landing in an open field to their left. The ATP passenger realized the airplane was going to collide with the trees. Just before the airplane collided with the trees, the pilot feathered the right engine. The ATP passenger observed the right propeller going into the feather position, and the propeller came to a complete stop. Examination of the right engine revealed no anomalies. Examination of the left engine revealed the starter adapter gear teeth had failed due to overload.

During an IFR flight at FL170, the pilot reported airframe icing and requested a higher altitude. The pilot climbed to FL210 where he started a descent and reported loss of manifold pressure in the left engine. The pilot indicated that weather was in his flight path and descent was required to avoid icing. 90 seconds later the pilot transmitted '...losing it...'. Radar data indicated aircraft had an inflight breakup at approximately 17,000 feet msl. There was no evidence of mechanical or structural malfunction prior to the breakup. The aircraft did not have a complete current annual and de-ice equipment was inoperative. The pilot had no actual instrument experience and was not certified for multi engine IFR flight. The pilot had a medical history of anxiety attacks and had been taking prescription medication, Xanax and Tofranil, for approximately three years prior to the accident. The blood contained 1.2 mcg/ml of imipramine (Tofranil) and 2.6 mcg/ml desipramine (metabolite of Tofranil). Xanax (alprazolam) was not reported in blood toxicology. These drugs have been known to produce side effects that include poor judgement. The pilot, sole on board, was killed.

After takeoff from Salisbury-Wicomico County Regional Airport, while climbing, the pilot reported a double engine failure and attempted to return for an emergency landing. On final, while turning back to airport with the left throttle at idle, the airplane stalled and crashed half a mile short of runway. The aircraft was destroyed and all five occupants were killed.

En route from Knosville to Rome, the pilot encountered poor weather conditions with thunderstorm activity, clouds and heavy rain falls. While flying in clouds at an altitude of 4,000 feet, the airplane struck tree tops and crashed on the slope of a mountain. The wreckage was found five days later and the pilot, sole on board, was killed.

On a night approach to New Orleans-Lakefront Airport, the pilot encountered poor weather conditions with low ceiling. Unable to locate the runway, he abandoned the approach and initiated a go-around. Few minutes later, during a second attempt to land, he decided to descend below MDA when the twin engine airplane struck the water surface and crashed into Lake Pontchartrain few miles short of runway. All three occupants were killed but only two bodies were recovered.

On a night approach to Athens-McMinn County Airport, the pilot lost control of the aircraft that crashed in flames by the runway. The aircraft was destroyed and both occupants were killed.

A United Air Lines, Inc., Vickers Viscount 745D, N7405, Flight 823, crashed 2-1/4 rules northeast of Parrottsville Tennessee, at 1815 e.s.t., July 9, 1964. Thirty-four passengers and the four crew members died in the crash. One passenger died of injuries following a free fall from the aircraft before the crash. The aircraft was destroyed by fire and impact damage. Flight 823 was a regularly scheduled operation from Philadelphia, Pennsylvania, to Huntsville, Alabama, with en route stops at Washington, D. C., and Knoxville, Tennessee. The flight operated without any reported discrepancies or difficulties until approximately 1810 e.s.t., when it was observed flying at low altitude trailing smoke. The flight continued in a southwesterly direction and at a point approximately 1.6 nautical rules before the impact site, a passenger was seen falling from the aircraft, and a short time later a cabin window was seen falling. The aircraft was then observed going into a nose-high attitude, the left wing and the nose went down, and the aircraft dived into the ground, exploded, and burned.

While cruising in a limited visibility due to snow showers, the twin engine aircraft struck the slope of a mountain and crashed in flames near Knoxville. All six occupants were killed. At the time of the accident, the ceiling was at 2,000 feet and the visibility was limited due to snow falls. Also, the mountain was shrouded in clouds.

On August 6, 1962, at 1731 e.s.t., Flight 414, an American Airlines, Inc., Lockhead Electra, N 6102A, crashed during a landing on runway 4L at McGhee-Tyson Airport, Knoxville, Tennessee. Sixty-seven passengers and five crew members were on board the aircraft. All escaped injury except one passenger who suffered a minor injury. The aircraft was substantially damaged. During the landing made by the captain in an area of thunderstorm activity and heavy rain showers, the aircraft skidded to the right off the runway. It struck a newly constructed taxiway the surface of which was approximately 17 inches above ground level, causing failure of the right main landing gear. The right wing became separated front the aircraft. The remainder of the aircraft continued to deviate to the right off the side of the runway for a short distance and came to rest 3,010 feet from the approach end of the runway on a heading of 200 degrees magnetic.
