Fort Lauderdale-Hollywood

The pilot was deviating around weather during descent when he noted the fuel flow and manifold pressure on the left engine oscillating. Because the propeller was still turning he elected not to feather the left propeller. The airplane would not maintain altitude so he lowered the landing gear and ditched the airplane in a swamp. Examination of the left fuel tank revealed the fuel float valve actuators and float arms excessively worn. This condition would allow unmetered air into the fuel lines. Also noted was the condition of one of the left fuel valves that could jam open allowing the fuel pickup to unport and induce excessive air into the fuel lines.

Crashed in unknown circumstances upon landing at South Bimini Airport. The pilot, sole on board, was uninjured.

The crew reported over radio that the #4 engine failed shortly after takeoff, and they were attempting to dump fuel when the #2 engine overheated. They then intentionally ditched the airplane. The wreckage was recovered about 2 weeks afterward, and the airplane was about 50% corroded away. Due to massive salt water corrosion, no preimpact failure/malfunction of the #4 engine could be identified. No record of airplane/operator being granted cfr part 129 certificate authority. No substantiation of the times in service for the airplane, engines, propellers, and time change components or airworthiness directives could be determined.

As the airplane was deviating around low intensity weather returns, and passing through 20,500 feet during climb out, it departed controlled flight and entered a right spiral. Descent rates exceeded 16,600 fpm during the descent from 18,300 feet to 3,900 feet and then slowed. Witnesses stated they saw the airplane descend from the clouds in a right flap spin. The empennage had separated from the airplane in pieces. Pieces of the wreckage were found up to 1.5 mile from the primary impact point. Both wings remained attached. The right engine was flamed out, and the propeller was feathered at impact. No mechanical reason for the flameout could be determined. At no time did the pilot indicate he was having difficulties. The NTSB weather study indicated that moderate turbulence was present in the area. The pilot's toxicology tests found 0.151 ug/ml of chlorpheniramine in the blood; normal therapeutic concentration is 0.01 to 0.04. Effects of overdosage include sedation, diminished mental alertness, and cardiovascular collapse to stimulation. The pilot, sole on board, was killed.

During cruise flight, the pilot reported that the right engine cowling partially separated and the left forward cylinder of that engine separated, followed by an engine compartment fire. He attempted to feather the propeller but was unable. He initiated a descent to extinguish the fire and was successful but after leveling off, was unable to maintain directional control. He ditched the airplane and both he and the passenger exited the aircraft. The pilot dragged the seriously injured passenger with him to a nearby island where they were rescued the following day. The aircraft was not recovered; therefore, no determination could be made as to the reason for the separation of the cylinder. Review of the aircraft logbook indicates that on 8/27/91, the n°5 cylinder of the right engine was removed and replaced. Also, the n°1 cylinder was removed and reinstalled following repair. There were no further entries in the aircraft logbook regarding cylinder removal or replacement to the right engine.

The scheduled passenger flight departed without a flight plan and was last heard from while descending in attempt to remain in VFR conditions. Witnesses on the ground stated that there was extremely heavy rain and thunderstorms at the time of the accident. The wreckage was located the next day and evidence indicated that the airplane hit the ground in a 50° nose down attitude at a high rate of speed. Both occupants were killed.

The pilot stated that while in level flight the left engine failed and he observed a fire warning light and shut the engine down, the right engine then began to run rough and lose power. He then restarted the left engine but neither developed enough power to sustain flight. He executed a forced landing on a highway and struck a vehicle and a fire erupted. Examination of the left engine revealed a cross threaded fuel nozzle fitting and soot patterns aft of it. No cause for the right engine failure was found. No evidence of an annual inspection was found.

After encountering icing conditions in flight and experiencing problems maintaining altitudes and headings, the pilot elected to divert from his planned destination of Dayton, OH to Knoxville, TN. While on final approach after descending 1,300 feet below minimum procedure turn altitude followed by being told the aircraft was well above the glideslope, ATC instructed the pilot to maintain 3,000 feet. Shortly thereafter, ATC reported the mode C indicated 1,900. The pilot responded with 'engine quit'. The aircraft crashed in a pasture about 1 mile from the airport. The investigation revealed that the aircraft was not equipped to operate in icing conditions. The evidence indicated that the flaps and landing gear were extended. Approximately 40 lbs of cocaine were found onboard the aircraft. The tox report for the pilot disclosed .05 mg/l benzoylecognite (cocaine metabolite) in his blood. The pilot had received a weather briefing which included a freezing level at 7,000 feet and filed a flight plan requesting a cruising altitude of 14,000 feet. Both occupants were killed.

The aircraft had been abandoned in the Bahamas for approximately 7 months. A pilot, with no known flight time in a Cessna 421, flew it to Fort Lauderdale. Except to avoid clouds, he made the flight at a low altitude and airspeed. When asked why, he said he was trying to save the engines. The pilot then departed toward an area of dark clouds and thunderstorms. When he did not arrive at the destination, a search was initiated. The aircraft was found 4 days later where it crashed in a steep nose down attitude. Radar data showed the aircraft made several heading changes and was returning to the dep airport before it crashed. The forward part of the aircraft was buried in a swamp, but the aft edges of the wings, fuselage and empennage were visible above water. The props had rotational damages; no preimpact mechanical failure or malfunction was evident. An exam of the right eng revealed its #2 pushrods and rocker arms/shafts/retainers had been removed before flight. Also, a #2 spark plug was stowed with its ignition lead attached. The aircraft owner was not found. The pilot's medical certificate was dated 5/28/85.

The pilot reported to ground personnel at Fort Lauderdale that he was experiencing an avionics problem and the passenger entry door was sprung the day before when it was slammed; however, the pilot elected to depart. The aircraft wreckage was located on June 19 in the Everglades near Coral Springs, Florida. The aircraft impacted in a nose low attitude. Wreckage was scattered over an area 211 feet long by 55 feet wide. Investigation revealed no preimpact mechanical malfunctions/failures. The pilot, sole on board, was killed.
