Rockwell Aero Commander 520

Aircraft was destroyed when it struck power lines and the ground during a single engine go-around. Following a left engine shut down due to severe vibrations, the pilot overflew one airport to return to his home base. En route, he elected not to go to full power due to a 3 minutes limitation he did not want to exceed. The pilot overshot the runway while manually extending the nose gear and elected to attempt a right 270° turn to return to final while at 100-150 feet agl. Nose landing did not extend due to hydraulic pump being on left engine and no pressure. During the turn, the pilot lost control and the aircraft struck the wires. Investigation revealed that one of the blade pitch change links on the left prop had disconnected, allowing one blade to free float. The link pin assembly had backed out as a result of the safety screw backing out due to damaged and stripped threads and an improper length screw being installed. Props had 1/4' safety screws installed instead of 3/8'.

During a pleasure flight, the pilot reported that the right engine caught on fire. The pilot made a landing on dry lake bed and disembarked from the plane examination of the wreckage revealed that the path of the landing roll showed no signs of melted metal or debris. There was a large fuel stain visible around the remains of the right wing, right engine and right cowling. The engine components and accessories showed moderate heat distress with no evidence of a blow torch effect. The right wing fuel sump drain valve was located inside a cup of melted aliminum and was in the open position.

The aircraft was found abandoned. Wreckage scene indicates collision with trees prior to collision with terrain. Aircraft suspected of being used for illegal cargo operations. The pilot was not found.

The non-instrument rated pilot was on ferry flight from Bartlesville, OK to Ontario, CA. An en route stop was made at Tucumcari, NM, where the aircraft was refueled and 14 qts of oil was added to the left engine. The line boy who serviced the aircraft saw no visible oil leaks or spillage around the engine. While on the next leg of the flight, the aircraft crashed near interstate highway 40. Two witnesses that saw the crash stated rain was falling, the wind was blowing very strong and there were low ceilings. Reportedly, a squall line was moving thru the area and there was moderate to severe turbulence. An exam of the wreckage revealed the aircraft had crashed in a steep nose down attitude, with 20° to 30° left bank and at high speed. No preimpact, mechanical failures were found and both engines had evidence that they were operating during impact. The weather briefer said the pilot indicated he would fly around the area of precipitation and remain VFR. Radar info showed the pilot had been following the interstate highway and varying his alt between 7,900 and 6,300 feet msl. Both occupants were killed.

Crashed in unknown circumstances killing both occupants.

During departure, the pilot climbed in IFR conditions to 6,000 feet. After leveling, a frequency change was made and he was cleared to 8,000 feet, which he acknowledged. About 2 minutes later, the controller radioed to the pilot that he was about 4 miles north of the airway, but there was no reply from the pilot. Shortly after that radar contact was lost and the plane crashed in mountainous terrain. Several residents in the area reported hearing extremely loud engine noises followed by complete silence. An investigation revealed that both wings had separated outboard of their respective engine nacelle assemblies. An examination of the fractures revealed the wings had separated from positive overload. The leading edges of both wings had ballooned upward, indicative of extreme airspeed. The empennage had separated in a yaw and from right torsional overload. Parts of the aircraft were found within a 1 mile arc, north of the main impact area. The pilot's recent instrument experience could not be verified. All three occupants were killed. Turbulence was forecasted below 8,000 feet.

The pilot, sole on board, was completing a ferry flight from Pensacola to Baton Rouge. While in cruising altitude, he contacted ATC and reported an engine fire. Cleared to descend, he attempted an emergency landing in a field but on touchdown, the airplane crash landed as the landing gear were not fully extended. The pilot was seriously injured and the aircraft was damaged beyond repair.

The twin engine airplane crashed in unknown circumstances into the sea off Great Inagua Island. SAR operations were initiated but the wreckage nor both occupants were recovered.

En route from South Bimini to Tampico, Mexico, the airplane suffered a double engine failure. The pilot ditched the aircraft off New Orleans. Seriously injured, he was rescued but apparently died a week later.

While in cruising altitude on a flight from Portland from Sacramento in marginal weather conditions, the twin engine airplane suffered an airframe failure. It entered a dive and crashed in a field located near Cheshire, northwest of Eugene. The aircraft was totally destroyed and all seven occupants were killed.
