Following an uneventful flight from Munich, the crew started the descent to Kassel-Calden Airport. The visibility was reduced with local patches of fog. On approach to runway 22, the pilot-in-command failed to realize his altitude was insufficient when the aircraft struck trees and crashed in a wooded area located 4,500 meters short of runway threshold and 1,100 meters from the extended centerline. The aircraft was destroyed and all eight occupants were killed.

The twin engine airplane was completing a flight from south of France to Liverpool when it crashed in unknown circumstances in Creil, about 45 km north of Paris. The aircraft was destroyed and both occupants were killed.

While in cruise flight on Airway J79-121 en route to Orlando, Florida, from Teterboro, New Jersey, the flightcrew of N100TA, an IBEX Corporation Gates Learjet 23, was cleared by the Jacksonville Air Route Traffic Control Center to descend from its altitude of Flight Level 410 to Flight Level 390. The flightcrew acknowledged the clearance, and air traffic control observed the radar target descend. About 2 minutes later, the airplane crashed into the Atlantic Ocean, from a steep, high-speed descent about 12 miles from Savannah, Georgia. The air traffic controller made several unsuccessful attempts to contact the airplane. The pilots had reported no difficulties in any of their radio transmissions. The pilot, copilot, and the two passengers on board were killed. Beyond 1158:49, the program showed a gradual increase in indicated airspeed from 271 to 400 KIAS. The average rate of descent was 15,375 fpm based on the radar data using pressure altitude (mode C).

During the weather briefing the pilot was advised that VFR flight was not recommended due to low ceilings and poor visibility. The pilot responded he had to go to Fort Payne VFR because they have no instrument approach. A Jeppesen US (lo) 29 low alt enroute chart was found at the wreckage that had a line drawn traversing southwest out of the Chattanooga VOR between V-115 and V-115e. The MEA for these airways was 4,000 ft msl. Prior to departure the pilot as advised that tops were reported 4,500 ft with another layer at 9,000 ft. The pilot responded he was going to Fort Payne and they had no approach there. Approximately 2-1/2 min after takeoff the pilot reported "...looks like about 1500 is all we're gonna get right now." About 7 min later the pilot reported they were still VFR but might want to turn around. The aircraft impacted the top of a north/south ridge line at an elevation of 2,020 feet. The copilot was part of the company's management team. A passenger was seriously injured while six other occupants were killed.

The pilot was trying to land after both engines failed during takeoff after the aircraft was refueled with jet fuel instead of gasoline. The weather was IFR with fog, low ceiling and rain. The aircraft collided with trees during a forced landing and was destroyed by fire after impact. All three occupants were killed.

As the pilot was descending from 7,000 to 5,000 feet, he heard a loud bang, followed by a temporary vibration and a violent swerve to the right. He looked out the right window and thought the right engine had fallen off since all he could see was the tops of the engine mounts. The aircraft was controllable only after reducing the left engine power to idle. During a wheels up/forced landing, the plane tore through a fence, slid across a paved road, went over an embankment and began burning after it came to rest. The pilot received a back injury and had difficulty egressing. An investigation revealed the propeller hub had failed from fatigue which resulted in blade separation and subsequent engine tearaway. The engine had remained attached to the airframe by cables. Metallurgical examination of the hub revealed that the fatigue originated at a threaded grease fitting. Gouging was visible on the inner wall. A set of incorrect counterweights were found on the propeller. The counterweight's function was to reduce vibration.

The aircraft was 20 feet agl during landing when the crew heard a propeller go into beta mode and the aircraft yawed to the right. The pilot lost control of the aircraft and it collided with a snow bank which separated the wings from the fuselage. Impact damage made it impossible to tell why the propeller went into beta mode.

Crashed in unknown circumstances somewhere in Ecuador.

Prior to the FAF during a VOR/DME approach, the Merlin was cleared to change to the unicom frequency. The pilot of the Merlin contacted unicom and requested and airport advisory. The unicom operator replied that there was a pirep of 500 feet over the field with two miles visibility but 'zilch' over the water. Shortly after this contact the pilot of the AA-5A called on unicom turning final. The pilot of the AA-5A was given the same advisory as given to the Merlin and further advised that another aircraft was inbound for runway 14. The aircraft collided less than one mile northwest of the approach end of runway 14. AIM 157 recommends that VFR inbound flights broadcasting entering downwind and final. AIM 363 recommends that, when making an IFR approach to an airport not served by a tower or FSS and after ATC advises to change to advisory frequency, to broadcast intentions, including type approach, position and when over FAF inbound. All three occupants in both airplanes were killed.

The pilot received two weather briefings, one on the evening before the flight, another at 1009 EST, within three hours of the takeoff time. IFR conditions were forecasted at the uncontrolled, destination airport. The pilot filed an IFR flight plan, but did not list an alternate airport. The aircraft departed Boca Raton at 1257 EST. The flight was uneventful en route and all communications were normal. During arrival, the pilot was cleared for a VOR 3 approach to runway 16. The minimum descent altitude (MDS) for the approach was 800 feet MSL (595 feet AGL) and the minimum visibility was one mile. Several witnesses at and near the airport saw or heard the aircraft. They described the aircraft as crossing the airport from the west side to the east. Those who saw it described it to be approximately 150 to 200 feet AGL, in and out of the clouds. Reportedly, the aircraft then circled and crossed the airport again. Subsequently, it struck an 80 feet tree, then impacted the ground in a steep descent. There was no evidence of failure or malfunction of the airframe or powerplant before impact. The aircraft was estimated to be 46 lbs over the max gross weight limit during impact. All eight occupants were killed.
