Cessna 421B Golden Eagle II

En route from Olbia to Torino-Caselle Airport, the pilot was informed about the deterioration of the weather conditions and decided to divert to Genoa-Sestri-Cristoforo Colombo Airport. On approach, he was unable to establish on the localizer despite several attempts and finally initiated a go-around procedure. While circling in limited visibility, the aircraft struck the slope of a mountain. All five occupants were killed.

The airline transport pilot reported that shortly after takeoff from runway 36, he heard a loud noise from the left engine area, and observed smoke trailing the left engine nacelle. He confirmed that the left engine was losing power, and he feathered the left propeller. He was unable to maintain altitude, and the aircraft was force landed on wooded terrain. The aircraft caught fire on the ground after colliding with trees and was destroyed. An inspection of the left engine turbocharger revealed that the rotor shaft was seized, with evidence of metal transfer to the bearing journals.

Two foreign pilots took off VFR to remain in the vicinity of an airport on the outskirts of a metropolitan area. No record was found to show the airplane had been fueled either before or after the preceding flight. The flight crew contacted an area approach control and requested an ILS approach to test their ILS equipment without specifying an airport. Approach control issued and the flight crew accepted vectors to another airport for which the pilots had no approach plate or airport information. Vectors took the airplane about 25 miles from the departure airport. The flight crew requested to proceed back to the departure airport. A short time later, the flight crew declared an emergency due to low fuel, then radar contact was lost. Witnesses at a landfill heard an intermittent sound from the engine(s). The airplane came into their view with one engine running, then the engine sound ceased. They indicated the airplane went out of control and crashed, but one engine accelerated just before impact. A small fire was confined to the left wing. Both occupants were killed.

The pilot said he was on the takeoff ground roll at about 100 knots when he discovered that the control lock was still in place. The pilot said he attempted to remove the control lock but could not prior to the aircraft over running the departure end of the 3,400 foot long runway. The aircraft collided with a county sewage treatment building, separating the wings from the fuselage. The aircraft fuselage continued through the building and came to rest on rocks near the beach. All four occupants were seriously injured.

The 3 occupants aboard were: the owner in the left front seat, his wife in the right front seat, and a man hired by the owner to fly the airplane (seat location could not be determined). Prior to takeoff a man telephoned FSS for a weather briefing and to file an IFR flight plan. He told FSS the pilot's name was J. Hamlett; a J. Hamlett was not aboard (it was found later that Hamlett was the maiden name of the wife of the man hired to fly the airplane). Two minutes after takeoff the pilot was told to contact departure; the pilot acknowledged. This was the last recorded radio contact. The airplane collided with a hill obscured by ground fog about 3 miles east of the airport. The man hired to fly the airplane did not possess an airman certificate; his certificate was revoked 2 years prior to the accident. The owner had obtained his private certificate for airplane single-engine land about 1 month prior to the accident, and had not received any multi-engine instruction. All three occupants were killed.

While initiating a cross country flight, the eight place aircraft with nine persons aboard, impacted terrain shortly after takeoff. Ice had been seen on the wings and horizontal stabilizer, and icing conditions were present. The aircraft was over maximum gross weight by a minimum of 258 pounds, and the pilot held an expired student pilot certificate dated august 17, 1984. A copy of a private pilot certificate designating multiengine land and instrument was found in the pilot's personal belongings. Faa officials concluded that it was not a valid certificate. An application for a medical certificate dated may 30, 1991, indicated the pilot had 4,000 hours of flight time. This figure could not be verified. Just prior to takeoff the pilot was observed brushing snow off the wings. Following the accident granular ice was found on the aerodynamic surfaces. The pilot and two passengers were killed while six other occupants were injured.

A pilot (whose instrument currency could not be determined) took off at night in IMC. Shortly after takeoff, the aircraft crashed about 1.5 mile from the departure end of the runway. There was evidence that it impacted in an 85° right bank, nose down attitude at high speed. No preimpact part failure was found during the investigation; however, during a pre-purchase inspection on 10/16/90, several discrepancies were noted. These included an inop flight director, an autopilot malfunction and a misrigged flight control system that allowed the control wheel to indicate a left turn when the aircraft was in level flight. There was no record of these being repaired. Records showed the pitot-static system was last tested on 3/24/88. The pilot was taking sine-aid and tylenol for a chronic sinus infection. Although tox checks indicated the presence of 50.7 ug/ml of pseudoephedrine and 36.4 ug/ml of acetaminophen in the pilot's urine, none was found in his blood. The sinus cond could have affected the pilot's balance and equilibrium. All six occupants were killed.

As the aircraft (N21ST) was en route on a flight from Key West to Naples, FL, the pilot of another aircraft saw a 'fireball' in the vicinity of where N21ST subsequently crashed. When N21ST did not arrive, a search was initiated. The wreckage was found the next day at 1704 est, in the Everglades National Park, near Flamingo, FL. During impact, the main wreckage was buried in 30 feet of mud. The left outboard wing section (from just outboard of the engine nacelle to the wing tip) was found approximately 1 mile from the main wreckage. An exam revealed the wing had failed where the nacelle fuel tank and the aux fuel tank boost pumps were mounted. No exhaust system failure or leakage from the fuel tanks was found in the area of the fire. The greatest fire damage was at a point where the left nacelle fuel tank boost pump was mounted and aft from there to where the rear wing spar had burned thru. The electrical fuel boost pumps were not recovered after the accident. The ignition source for the fire was not determined. All three occupants were killed.

Shortly after takeoff, the aircraft was seen flying low over trees, followed by a rapid roll to the left and a collision with wooded terrain. One witness reported seeing gray smoke trailing the left engine before the crash. An inspection of the wreckage revealed the left engine spark plugs were black and heavily sooted. Neither propeller had been feathered before the accident. The landing gear was found in an extended position. Further investigation revealed that Cessna multi-engine service bulletin (SB) 88-3 was not complied with. This SB modified the fuel system to provide for direct pilot (rather than automatic) actuation of the output pressure of the auxiliary fuel pumps. Both engines ran satisfactorily on a test stand following the accident. No other evidence of mechanical failure or malfunction was found. All three occupants were killed.

The crew was completing a training flight from Malta to Zurich and return with intermediate stops in Rome and Basel. While on an ILS approach to Zurich-Kloten Airport runway 14, while at an altitude of 600 meters, the twin engine aircraft deviated from the glide, proceeded to a flat attitude when it entered a rapid descent and crashed 1,500 meters short of runway. The aircraft was damaged beyond repair and both occupants were seriously injured.
