Circumstances:
According to a statement provided by the Jacksonville Center air traffic control (ATC) facility, the pilot contacted ATC while at flight level 270. About 25 minutes later, the airplane began to deviate from the ATC-assigned altitude and route. The controller’s attempts to contact the pilot were unsuccessful. The North American Aerospace Defense Command launched military fighter aircraft to intercept the airplane. The military pilots reported that the airplane was circling in a left turn at a high altitude and low airspeed and that its windows were partially frosted over. They also reported that the pilot was slumped over in the cockpit and not moving. They fired flares, and the pilot continued to be unresponsive. The airplane circled for about 3 hours before it descended into the Gulf of Mexico and sank. The pilot and airplane were not recovered. Review of the pilot’s Federal Aviation Administration medical records did not reveal any recent medical conditions that would have deemed him unfit to fly.
Probable cause:
Pilot incapacitation, which resulted in the pilot’s inability to maintain airplane control and the airplane’s subsequent ocean impact.

Circumstances:
About 2 hours into a cross-country flight over water, the pilot heard a noticeable change in engine noise and observed erratic engine torque readings. Moments later the airplane experienced a complete loss of engine power. After declaring an emergency, the pilot attempted to diagnose the problem and restart the engine to no avail. The airplane ditched 175 miles from land, in water over 5,000 feet deep. The airplane was not recovered and the reason for the loss of engine power could not be determined.
Probable cause:
A total loss of engine power for undetermined reasons.

Circumstances:
The pilot Angel Lenin Iglesias Hernández stole the aircraft at Pinar del Río Airport, took off with nine of his family members and elected to reach Florida. En route, the aircraft ran out of fuel and crashed in the Gulf of Mexico about 145 km southwest of Key West. A passenger was killed while nine other occupants were rescued by the crew of the bulk carrier christened 'Chios Dream'.
Probable cause:
Engine failure due to fuel exhaustion.

Captain / Total flying hours:
1500
Circumstances:
The airplane was en route at 14,000 feet msl when the manifold pressure dropped from 30 to 18 inches. Eleven minutes later the oil light came 'on'. The airplane continued under partial power at an airspeed of 90 knots, while descending at 100 to 300 feet per minute (fpm). By 9,500 feet msl the engine oil pressure dropped to zero. The pilot shut down the engine and made a forced landing in the Gulf of Mexico near a ship. The airplane remained afloat for 5 to 7 minutes. During this time, the emergency exit was opened, all occupants donned a life vest, exited, and boarded the life raft, which the pilot had deployed. All were rescued by personnel from the ship. The airplane was not recovered; therefore, the cause of the power loss was not determined.
Probable cause:
A total loss of engine power with the cause undetermined. A factor was the lack of suitable terrain for the forced landing.

He became lost and disoriented so he decided to ditch the airplane about 375 miles southeast of Brownsville, Texas. The aircraft sank and was lost while both occupants were rescued.
Probable cause:
The pilot became lost and disoriented after encountering severe electrical storm in flight.

Circumstances:
The aircraft crashed into the Gulf of Mexico while en route to New Orleans, Louisiana, from West Palm Beach, Florida. Only the pilot and copilot were on board the aircraft. About 2 1/2 minutes after the aircraft was reported at Flight Level 430 in the vicinity of the Covia Intersection on Airway J58, the Jacksonville, Florida, Air Route Traffic Control Center received an unusual staccato sound transmission over the frequency, followed 18 seconds later by a report from the copilot, "Can't get it up...it's in a spin..." About 33 seconds after the first staccato sounds, radio and radar contact with N125NE was lost about 104 miles west of Sarasota, Florida. Floating debris were located by a search aircraft and later recovered; the flightcrew was not found. There were no known witnesses to the crash.
Probable cause:
An unexpected encounter with moderate to severe clear air turbulence, the flightcrew's improper response to the encounter, and the aircraft's marginal controllability characteristics when flown at and beyond the boundary of its high altitude speed envelope, all of which resulted in the aircraft exceeding its Mach limits and a progressive loss of control from which recovery was not possible. Contributing to the accident was the disconnection of the Mach overspeed warning horn with an unauthorized cut-out switch which resulted in the absence of an overspeed warning that probably delayed the crew's response to the turbulence encounter, and the insonsistencies in aircraft flight manuals and flightcrew training programs regarding the use of spoilers to regain control.

Circumstances:
En route from Miami to San Juan, the airplane suffered a major electrical failure. The crew lost his orientation and flew to the west over the Gulf of Mexico. Eventually, the captain elected to ditch the aircraft that crashed into the sea about 125 miles south of Fort Walton Beach, Florida. The crew of the merchant ship 'St Mary' was able to rescue three people while a crew member was killed.
Probable cause:
The aircraft was ditched after the crew became lost/disoriented following the failure of the electrical system. A forced landing off airport on water was completed after the airplane became low on fuel. The exact cause of the electrical failure could not be determined.
