Circumstances:
The pilot departed his home base in VFR conditions without filing a flight plan and did not request or receive a preflight or en route weather briefing from the FAA. While en route, he contacted Southern California TRACON (SOCAL) and requested an ILS runway 26 approach to the destination airport. SOCAL cleared the pilot for the approach and to change to an advisory frequency. There was no current weather report available at the airport because the tower was closed, but another pilot who was on the same frequency stated that the airport weather was 'zero zero.' (An automated weather observation system at the airport recorded 'zero zero' conditions near the time of the accident.) Ground witnesses heard the airplane as the pilot began a missed approach. However, the airplane collided with trees and a snack bar building about 1/4 mile northwest of the departure end of the runway. Impact occurred as the airplane was in a right turn through a heading of 345 degrees, which was the opposite direction of turn for the missed approach procedure. Toxicology test of the pilot's blood showed 1.518 mcg/ml Fenfluramine and 0.678 mcg/ml Phentermine; these are appetite suppressant drugs that are chemically related to amphetamines and have a high incidence of abuse. Neither of these drugs was approved by the FAA for use while flying aircraft. The amount of Fenfluramine in the pilot's blood was above a normal level for control of appetite.
Probable cause:
The pilot's impairment of judgment and performance due to drugs, his resultant improper planning/decision, his failure to follow proper IFR procedures, and his failure to maintain proper altitude during a missed approach. Factors relating to the accident were: the pilot's inadequate weather evaluation, and the adverse weather condition (below landing minimums).

Circumstances:
A Beech liner, Boeing 757 and Israel Westwind (WW) were vectored for landings on runway 19R. The 757 and WW were sequenced for visual approaches behind the Beech. Before being cleared for visual approach, the WW was closing 3.5 miles from the 757 on a converging course. The 757 and WW crews were told to slow to 150 knots. The 757 slowed below 150 knots and was high on final approach with a 5.6° descent. The WW continued to converge to about 2.1 miles behind the 757 on a 3° approach. ATC did not specifically advise, and was not required by ATC handbook to advise, the WW pilots that they were behind a Boeing 757. Captain discussed possible wake turbulence, flew ILS 1 dot high, noted closeness to the 757 and indicated there should be no problem. While descending thru approximately 1,100 feet msl, the WW encountered wake turbulence from the 757, rolled into a steep descent and crashed. The crew lacked specific wake turbulence training. Chlorpheniramine (common over-the-counter anti-histamine; not approved for flying) detected in pilot's lung tissue (0.094 ug/ml).
Probable cause:
The pilot-in-command's failure to maintain adequate separation behind the Boeing 757 and/or remain above its flight path during the approach, which resulted in an encounter with wake vortices from the 757. Factors related to the accident were: an inadequacy in the ATC procedure related to visual approaches and VFR operations behind heavier airplanes, and the resultant lack of information to the Westwind pilots for them to determine the relative flight path of their airplane with respect to the boeing 757's flight path.

Aircraft flight hours:

Circumstances:
Due to the impending arrival of a snow storm, the certificated commercial pilot and 5 passengers departed one day earlier than planned, from an uncontrolled airport located in mountainous terrain to begin a night, cross country flight. Instrument meteorological conditions prevailed. Prior to departure, the pilot was given an ifr clearance void time from an ARTCC. The pilot was climbing toward a VOR located about 27 miles southeast of the departure airport while attempting to contact the ARTCC to open his instrument flight plan. The pilot failed to maintain terrain clearance, and became lost/disoriented. The airplane struck trees and snow covered terrain at 10,200 feet msl, 7 nautical miles and about 22° to the right of the intended course. Four passengers were killed while two other occupants, among them the pilot, were injured.
Probable cause:
The failure of the pilot to plan and conduct his departure flight to avoid high mountainous terrain, during which the pilot became lost/disoriented. Contributing to the accident was self induced pressure to depart before the arrival of a snow storm.

Circumstances:
En route from La Verne to La Grande, while in cruising altitude, a wing separated and detached. Out of control, the airplane entered a spin and crashed in flames. The pilot, sole on board, was killed.
Probable cause:
Airframe failure in flight and uncontrolled descent after the pilot exceeded designed stress limits of aircraft. The following findings were reported:
- Wings spars,
- Overload failure,
- Separation in flight,
- Wings separated.

Circumstances:
During the takeoff roll at La Verne-Brackett Field Airport, the pilot-in-command noticed a problem and decided to abandon the takeoff. He initiated an emergency braking procedure but unable to stop within the remaining distance, the twin engine airplane overran, lost its undercarriage and came to rest. Two passengers were killed while five others occupants were injured. The aircraft was destroyed.
Probable cause:
Inadequate preflight preparation on part of the flying crew. The following factors were reported:
- Aborted takeoff,
- Gear collapsed,
- Delayed action in aborting takeoff,
- Gust locks engaged,
- Failed to use the pre-takeoff checklist,
- Overload failure,
- Airport conditions,
- Bolt secued control column,
- Pax seats improperly installed.
