Circumstances:
The flight originated at 1235. The pilot performed two fly-by passes for the dedication of a nearby mall. The pilot radioed for clearance to land at the private airport which he owned. He was given clearance to land and told the wind was from the south at 20 knots. The pilot landed on runway 09. During landing roll, the airplane was seen to nose over. The cockpit, cabin, and left wing of the airplane were consumed by fire. The passenger escaped through the over-wing emergency exit on the right side of the cabin. He stated the pilot was lying near the rear door and would not respond to stimulus. The investigation revealed two skid marks in the grass which terminated at the airplane wreckage. The mark made by the right main landing gear was 750 feet long. The skid mark made by the left main landing gear was 560 feet long. The passenger was seriously injured and the pilot was killed.
Probable cause:
Excessive use of brakes by the pilot-in-command.

Circumstances:
On final approach to the Sepahua Airstrip, the captain noticed a thin layer of mist over the runway and decided to make a low pass to assess the situation. While passing over the runway at low height, he lost control of the airplane that rolled to the right then overturned and eventually crashed in a river located near the runway end. One pilot was injured and the second was killed.
Probable cause:
The exact cause of the loss of control could not be established. Nevertheless, it is possible that the captain remembered at the last moment the presence of a radio antenna located about 40 metres from his position and maybe lost control of the airplane after initiating an evasive maneuver.

Circumstances:
The twin engine aircraft departed Lakeba Island Airport on a cargo flight to Suva, carrying one passenger, one pilot and a load of fish. On final approach to Suva-Nausori Airport runway 10, the pilot encountered strong winds. On short final, the aircraft was too low and collided with a taxi driving on a road passing about 200 metres short of runway 10 threshold. The aircraft went out of control and crashed, bursting into flames. Both occupants in the plane were killed while both occupants in the taxi were seriously injured.
Probable cause:
The pilot was completing the approach at an insufficient altitude. Strong winds were considered as a contributing factor.

Circumstances:
The pilot of a twin-engine cargo airplane shut down the left engine and feathered the propeller due to a loss of engine oil. The FAA ARTCC handling the flight vectored the airplane toward a VOR. Due to the airplane's altitude and distance from the center's radar, the pilot of the airplane had to perform a full instrument approach procedure. The airplane maintained its enroute assigned altitude until passing the VOR outbound. Ntap readouts show the airplane descending throughout the procedure turn and inbound leg of the approach. The airplane's last radar contact was 300 feet below the inbound altitude for the approach while outside the final approach fix. The airplane collided with trees and terrain approximately 2 1/4 miles from the airport. The VOR is 5.5 miles from the airport. The on-scene investigation revealed the left engine's propeller had been feathered, its number nine cylinder mounting studs on the engine's case were crushed downward or were broken off at the case's surface, and the landing gear had been extended. The pilot, sole on board, was killed.
Probable cause:
The National Transportation Safety Board determines the probable cause(s) of this accident to be: was a pre-mature extension of the landing gear by the pilot which resulted in the inability of
the pilot to maintain the minimum descent altitude. Factors related to the accident were the loose cylinder and loss of oil.

Circumstances:
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.
Probable cause:
Improper planning/decision by the pilot, which resulted in fuel exhaustion, due to an inadequate supply of fuel, and the pilot's failure to maintain control of the airplane during approach to an emergency landing. A related factor was: failure of the pilot to refuel the airplane before flight.

Circumstances:
A student pilot in American AA-1A, N9317L, was on an approach to land on runway 05 of the uncontrolled airport, as a commercial pilot in Cessna 414A, N47WD, was on an approach to land on runway 14. The two runways intersected near their approach ends. The two aircraft collided as they were about to touch down at dusk over the intersection. Witnesses on the ground stated that they observed lights on the Cessna, but did not observe any lights on the American. Witnesses in other aircraft in the area stated that they heard the pilot of the american announcing his position in the traffic pattern and landing intentions, but did not hear the pilot of the Cessna on the Unicom frequency. The pilot of the Cessna stated that he announced his intention to land on runway 14 over Unicom frequency 123.0. The published Unicom frequency for the Statesboro Airport was 122.8.
Probable cause:
Inadequate visual lookout by the pilots of both aircraft. Factors related to the accident were: failure of the pilot of N9317L to illuminate his aircraft navigation lights, and improper radio communications by the pilot of N47WD by selecting the wrong unicom frequency to monitor and announce his landing intentions and position.

Aircraft flight hours:

Circumstances:
While cruising at FL240, a propeller (prop) hub arm on the left prop failed, releasing the prop blade, which struck a 2nd blade, breaking off its tip. This resulted in a severe engine vibration and shutdown of the left engine. The left engine was forced downward and inboard on its mounts. The cabin depressurized, possibly from blade contact. The flight crew made an emergency descent and received a vector to divert for an ILS approach to Dubuque. The airplane was incapable of maintaining altitude and descended in instrument conditions. Subsequently, it collided with a silo and crashed about 8 miles south of Dubuque. An investigation revealed the left prop hub failed from fatigue that initiated from multiple initiation sites on the inside diameter surface of the hole for the pilot tube. There was evidence that the fatigue properties of the hub were reduced by a combination of factors, including machining marks or scratches, mixed microstructure, corrosion, decarburization, and residual stresses. All eight occupants were killed, among them George Mickelson, 52, Governor of South Dakota.
Probable cause:
The fatigue cracking and fracture of the propeller hub arm. The resultant separation of the hub arm and the propeller blade damaged the engine, nacelle, wing, and fuselage, thereby causing significant degradation to aircraft performance and control that made a successful landing problematic. The cause of the propeller hub arm fracture was a reduction in the fatigue strength of the material because of manufacturing and time-related factors (decarburization, residual stress, corrosion, mixed microstructure, and machining/scoring marks) that reduced the fatigue resistance of the material, probably combined with exposure to higher-than-normal cyclic loads during operation of the propeller at a critical vibration frequency (reactionless mode), which was not appropriately considered during the airplane/propeller certification process.
