Circumstances:
After crossing the mondi intersection inbound for an ILS runway 05 approach, the captain felt that a proper descent was not possible due to a strong tailwind and their present altitude. They turned and proceeded outbound to lose altitude. The crew then established themselves again on the inbound course at an airspeed of approximately 120 knots. The copilot reported that around 300 feet "the bottom dropped out." the aircraft crashed onto the surface of a frozen cove and slid onto marshy terrain and stopped about 500 feet short of the runway. An NTSB weather summary shows that the following wind regimes existed when the aircraft made its approach: 5,000 to 24,000 ft asl, wind 220/50; 2,400 to 450 feet asl, wind 180/30; 450 feet asl to surface, wind 100/5. Using the above wind regimes and assuming an approach airspeed of 123 knots, the following ground speeds were computed: 5,000 to 2,400 ft asl, 155 knots; 2,400 to 450 feet asl, 147 knots; 450 feet asl to surface, 118 knots.

Circumstances:
The aircraft crashed during an instrument approach in IMC at Spokane-Intl Airport. The aircraft hit a hill about 4.5 miles from the runway threshold at an elevation of 2,546 feet. The minimum descent altitude for the instrument approach procedure was 2,760 feet. Of the nine persons aboard flight 201, seven were killed and two were injured seriously. The instrument approach procedure the fiightcrew used required that a altitude of 3,500 feet be maintained until the aircraft passed the final approach fix, located 4,5 miles from the runway threshold. The aircraft impacted the ground near the location of the final approach fix, which was about 1,800 feet southeast of the Spokane VORTAC.
Probable cause:
A premature descent to minimum descent altitude (MDA) based on the flight crew's use of an incorrect distance measuring equipment (DME) frequency and the flight crew's subsequent failure to remain at or above MDA. Contributing to the cause of the accident was the design of the DME mode selector which does not depict the frequency selected and the failure of the flight crew to identify the localizer DME facility.

Circumstances:
The pilot was completing a positioning flight to Chicago-Merrill C. Meigs Airport and while descending, he encountered poor weather conditions with low ceiling, fog and limited visibility. He lost control of the airplane that crashed into Lake Michigan. Few debris were found while the main wreckage was not recovered. Both occupants were presumed dead.
Probable cause:
Loss of control on final approach after the pilot suffered a spatial disorientation. The following contributing factors were reported:
- Initiated flight in adverse weather conditions,
- Low ceiling,
- Fog,
- Visibility limited to one mile or less.

Circumstances:
Columbia Pacific Airlines Flight 23, a Beech 99 (N199EA), was operated under the provisions of 14 CFR 135 as a regularly scheduled passenger flight from Richland to Seattle, Washington. The crew arrived at Richland at 1525 P.s.t. on Flight 18 from Seattle. When they arrived, N199EA was being inspected to fulfill the requirements of an Airworthiness Directive. The aircraft was not available to the crew for preflight inspection until 1630; Flight 23 was scheduled to depart at 1640. At 1628, the captain was briefed on weather by the Walla Walla, Washington, Flight Service Station (FSS), and he filed a dispatch release which contained aircraft weight and balance, route of flight, and weather information. About 1630, the aircraft was fueled and 600 lbs of baggage was loaded. About 1635, the first officer left the terminal building and connected the auxiliary power unit to the aircraft. He then inspected the aircraft and boarded; the captain boarded shortly thereafter. When the passenger boarding call was made, the captain left the aircraft to obtain magazines for the passengers. He was seen getting into his seat when the first passenger boarded. At 1646, the first officer contacted the Pasco Airport Traffic Control Tower, using Flight No. 29, and advised that they were taxiing and would request an instrument flight rules clearance to Seattle via Yakima, Washington, when airborne. The Pasco Control Tower received no further calls from Flight 23. The first officer informed operations on company frequency that they would be departing shortly and would relay their estimated time of arrival in Seattle when airborne. There were no further radio communications with the crew. The aircraft daily flight log for February 10 showed that the aircraft left the ramp at 1645 and took off at 1648. In general, witnesses described the aircraft's attitude at liftoff as normal and estimated the point of liftoff between 1,173 and 1,486 ft; however, immediately thereafter the aircraft began a steep climb at an angle of 20' to 45" to an altitude of 300 to 400 ft above the runway and then appeared to decelerate. The wings rocked or wobbled at the top of the climb, and the aircraft turned or yawed to the left.
The nose dropped and the aircraft descended to the ground at a flightpath angle estimated to have been 45°. Fuel from ruptured fuel tanks caught fire after the aircraft hit the ground. Fire consumed the aircraft within 7 minutes. All 17 occupants were killed.
Probable cause:
The National Transportation Safety Board determines that the probable cause of the accident was the failure or inability of the flightcrew to prevent a rapid pitchup and stall by exerting sufficient push force on the control wheel. The pitchup was induced by the combination of a mistrimmed horizontal stabilizer and a center of gravity near the aircraft's aft limit. The mistrimed condition resulted from discrepancies in the aircraft's trim system and the flightcrew's probable preoccupation with making a timely departure. Additionally, a malfunctioning stabilizer trim actuator detracted from the flightcrew's efforts to prevent the stall. Contributing to the accident were inadequate flightcrew training, inadequate trim warning system check procedures, inadequate maintenance procedures, and ineffective FAA surveillance.

- Improper IFR operation,
- Low ceiling,
- Rain,
- Fog,
- Visibility two miles or less,
- Weather conditions below minimums,

- Snow,
- Icing conditions including sleet and freezing rain,
