Circumstances:
The airplane collided with a berm following a loss of directional control while landing. The airplane was on a 14 CFR Part 91 positioning flight at the time of the accident. The pilots reported that they encountered what they thought were rough spots on the runway during the takeoff roll. The captain reported that after takeoff, he called for the co-pilot to raise the gear and engage the yaw damper. The crew then noticed an unsafe gear indication for the nose gear. The captain stated they leveled off at 5,000 feet and decreased the airspeed so they could recycled the landing gear. Cycling the landing gear did not resolve the problem. The crew then requested to return to the departure airport for landing. The landing gear was extended and a gear down and locked indication for all three landing gear was observed. The captain stated that on touchdown, the co-pilot extended the spoilers and armed the thrust reversers. He stated that after the nose wheel touched down the airplane made a sharp left turn and traveled off the side of the runway through the grass. The airplane contacted a four-foot high berm prior to coming to a stop on another runway. The captain stated he attempted to taxi the airplane only to discover that they did not have any nose wheel steering. Post accident inspection revealed the seal on the nose gear strut had failed which prevented the nose gear from centering.
Probable cause:
The pilot was not able to maintain directional control of the airplane due to the failure of the nose gear strut seal which prevented the nose wheel from centering. A factor associated with the accident was the berm that the airplane contacted.

Circumstances:
On December 14, 2004 at 1230 central standard time, an Aero Commander AC-685 twin-engine airplane, Mexican registration XB-GSG, was destroyed upon impact with terrain following a loss of control while maneuvering near Apodaca, State of Nuevo Leon, in the Republic of Mexico. The two commercial pilots and 3 passengers were fatally injured. The airplane, serial number 12058, was registered to a private individual. The flight originated from the Monterrey Del Norte Airport, near Monterrey, State of Nuevo Leon, Mexico, approximately 1225 and was en route to the McAllen-Miller International Airport (MFE), near McAllen, Texas, with Houston, Texas, as its final destination. Visual meteorological conditions prevailed for the business flight for which an instrument flight rules (IFR) flight plan was filed. According to local authorities the airplane was attempting to return to the airport when the accident occurred. The wreckage of the airplane was located on the 350-degree radial from the Monterrey VOR (ADN), for 2.3 nautical miles. A post-impact fire destroyed the aircraft. A post-impact fire consumed the aircraft.

Circumstances:
The 9,500-hour ATP-rated pilot was forced to secure the left engine during a maintenance test flight following the malfunction of the left propeller. The crew executed single-engine instrument landing system (ILS) approach to runway 13. During short final, the crew noticed that the alternator light was illuminated and the hydraulic pressure gauge indicated "0" pressure. The landing gear was already extended and the flaps were partially extended, so the crew elected to continue the approach to a full-stop landing. Upon landing, the pilot immediately turned on the direct current (DC) hydraulic pump. The pilot added that he then realized that he was unable to maintain directional control of the airplane due to the lack of nose wheel steering and the ineffective wheel brakes. As a result, the airplane continued to veer to the right and exited the runway. The airplane collided with the airport perimeter fence and continued down into a drainage ditch. The examination of the aircraft revealed that the hydraulic pump switch did not appear as if it had been turned on.
Probable cause:
The failure to activate the hydraulic pump which resulted in the pilot's inability to maintain directional control.

Circumstances:
About 18 minutes after takeoff, the pilot radioed that the n°2 engine had lost power and that he was returning to land at Mcallen. While approaching to land, the aircraft crashed in an open field about 400 yards short of the runway and 115 feet right of the approach lights. During impact, the aircraft was in an inverted attitude, in about a 150 degree right roll and 15 degrees nose down. After impact, an intense fire erupted. An examination of the wreckage revealed no preimpact malfunction or failure except that the right propeller blades were set at 65 degrees. The angle of the blades should have been 86 degrees when in the full feathered position. The aircraft was estimated to be 753 lbs over its maximum gross weight limit at the time of the accident. With the gear down and flaps up, the vmc was calculated to be 92 mph with the propeller windmilling and 87 mph with the propeller feathered.

Circumstances:
While on a return flight to their company headquarters in McAllen, Texas, from Thermopolis, Wyoming, the president of Sky Train Air Inc., the chief pilot, and another company pilot stopped in Casper, Wyoming, for fuel. The lineman noted a fuel imbalance when 320 gallons of fuel were added to the left wing and only 260 gallons of fuel were added to the right wing tanks. According to the lineman, the crew was aware of the imbalance. A total of 585 gallons of Jet-A with Prist (anti-ice additive) was supplied which filled the wing tanks to capacity. No fuel transferring was necessary during the refueling. The lineman stated that he believed the fuselage tank was full because the nosegear strut was extended 6 to 12 inches. We stated a ground power unit was used to start the engines and he did not notice any difficulties with the aircraft during the crew's preflight checks. The flight plan filed by the president, reported to be the pilot-in-command, as follows: IFR to McAllen, Texas, at Flight Level (FL) 450, true airspeed 450 knots, Airway J170 to Denver, J17 to Amarillo, J17 to San Antonio, J25 to Corpus Christi, direct McAllen; time en route 2 hours 20 minutes with 3 hours 40 minutes of fuel on board. A weather briefing was not given to him because he had reported that he already had the weather information. The crew called the Casper Air Traffic Control Tower for taxi clearance at 1352:08 and began its departure from runway 21 at 1357:02. At 1449:39, while in cruise flight at FL 450, the flightcrew made initial radio contact with Sector 71 of the Albuquerque Air Route Traffic Control Center (ARTCC). The aircraft was "squawking" transponder code 0670. About 1458, a new controller took over the radar and data positions. At 1459:36, he issued a frequency change to which the crew did not respond. At the time, the controller noticed no transponder target reply from the aircraft. Until 1501:39, he made several attempts to contact the aircraft, but received no response. Albuquerque ARTCC radar computer data showed that radar contact with the aircraft was lost at 1458:07 at FL447. Five witnesses at Felt, Oklahoma, located in the southwest portion of the Panhandle, heard an aircraft overhead at a very high speed. One witness stated that he heard a vibration sound which indicated to him the aircraft was overspeeding. Another witness stated that the aircraft was about lo break the sound barrier. Of the five witnesses interviewed, only one saw the aircraft - and only momentarily - and he stated the aircraft was in about a 45° descent angle and the wings appeared to be rocking up and down. All the witnesses stated that they heard an explosion and saw a mushroom cloud of black smoke erupt when the aircraft crashed to the ground. The accident occurred at approximately 1502LT. The aircraft crashed 2.5 miles southwest of Felt, Oklahoma. All three occupants were killed.
Probable cause:
A loss of control, possibly initiated by an unexpected encounter with moderate to severe clear air turbulence, which caused the aircraft to depart the narrow flight envelope boundaries in which it was operating and from which recovery was not effected, the flightcrew's lack of adequate training and experience in the Learjet; and the aircraft's marginal controllability characteristics near and beyond the boundaries of its flight envelope. Contributing to the accident was the flightcrew's probable extension of the spoilers in an overspeed situation, a procedure that had been prescribed in the approved aircraft flight manual until 1 year before the accident.
