Circumstances:
During the takeoff roll on runway 01R at San Francisco Airport, after the V1 speed was reach, the crew noticed vibrations while the aircraft started to slow down. The captain decided to abort the takeoff but unable to stop within the remaining runway, the airplane overran, lost its nose gear and engine n°2 before coming to rest in the San Francisco Bay, broken in two. All three crew members were evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The initiation of rejected takeoff procedures, beyond V1 speed, with insufficient runway remaining in which to stop the aircraft. The crew action was prompted by the failure of the two right truck rear tires which produced a noticeable aircraft vibration and a reduction in aircraft acceleration.

Circumstances:
Shortly after takeoff from Point Mugu NAS, while in initial climb, the right engine lost power and caught fire. The crew elected to return for an emergency landing when control was lost and the airplane crash landed by the runway and came to rest. All three occupants were slightly injured and the aircraft was damaged beyond repair. For unknown reason, the fire extinguishing system was inoperative.
Probable cause:
Partial loss of power on one engine during initial climb due to material failure. The following factors were reported:
- Failure of the fuel system,
- Failure of the fire extinguishing system,
- Engine fire,
- Component failure of right engine fuel feed system,
- Failure of hydraulic line.

The pilot failed to maintain directional control and failed to abort takeoff. The following factors were reported:
- Unfavorable wind conditions,
- Lack of familiarity with aircraft,
- No weather briefing received (no record),
- The pilot reported to have about an hour dual in type.

The aircraft was destroyed and all five occupants were killed.
Probable cause:
The pilot misjudged altitude and clearance after takeoff.

Circumstances:
Airwest flight 706, a DC-9, was to fly from Los Angeles, CA (LAX) to Seattle, WA (SEA) with intermediate stops at Salt Lake City (SLC), Boise (BOI), Lewiston (LWS), Pasco (PSC) and Yakima (YKM). The aircraft departed Los Angeles at 18:02. At 18:09 the crew reported leaving FL120 and Los Angeles ARTCC cleared them direct to Daggett. At 17:16 h a US Marine Corps McDonnell F-4B Phantom 151458 departed Naval Auxiliary Air Station (NAAS) Fallon for a flight to MCAS El Toro at low altitude. The aircraft had several technical difficulties, including an inoperative transponder and a leak in the oxygen system. Due to deteriorating visibility northwest of Palmdale, the crew climbed to 15,500 feet . Shortly after level-off, aircraft was 50 miles from MCAS El Toro. The pilot executed a 360° aileron roll at this time, which took approximately 3 seconds to complete. The Radar Intercept Officer (RIO) estimated that the true airspeed in the climb and after level-off was 420 knots. The F-4B collided with the Airwest DC-9 about 1 minute and 20 sec after the roll, at 15150 feet. After the collision, the F-4 began to tumble violently about the lateral axis. The RIO waited about 5 seconds, and, after seeing numerous warning lights in the cockpit, he ejected from the aircraft . The ejection was successful, and he parachuted to the ground without injury. The other F-4 crewmember did not survive the accident.
Probable cause:
The failure of both crews to see and avoid each other but it is recognized that they had only marginal capability to detect, assess, and avoid the collision. Other causal factors include a very high closure rate, comingling of IFR and VFR traffic in an area where the limitation of the ATC system precludes effective separation of such traffic, and failure of the crew of 151458 to request radar advisory service, particularly considering the fact that they had an inoperable transponder.

Aircraft flight cycles:

Circumstances:
The crew was completing a training flight from Los Angeles to Ontario. The pilot under supervision was supposed to complete an ILS approach with one engine inoperative, to make a missed approach and a go-around procedure. On final to runway 25R, the airplane went out of control and crashed in a field. The airplane was totally destroyed and all five crew members were killed.
Probable cause:
The failure of the aircraft rudder hydraulic actuator support fitting. The failure of the fitting resulted in the inapparent loss of left rudder control which, under the conditions of the flight, precluded the pilots’ ability to maintain directional control during a simulated engine-out missed-approach. The existing weather conditions degraded external visual cues, thereby hampering rapid assessment of aircraft performance by the flight check captain.
