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.

While conducting a Naval Air Training and Operating Procedures Standardization check the pilot at controls was allowed to perform his first attempt at shooting an obstacle approach at Whidbey Island NAS. This maneuver was inadequately briefed by the pilot in command during the mission brief. The pilot in command, having great confidence in the pilot at controls, allowed him to conduct this maneuver without prior demonstration. After pushing over for the approach an excessive sink rate developed. Upon determination that the approach was getting dangerous, power was applied and the nose pulled up. Due to the combination of slow approach speed, late and in inadequate power application, the excessive sink rate was not arrested, resulting in a hard landing followed by failure of the starboard wing.

Shortly after takeoff from Everett-Paine Field Airport, the twin engine airplane encountered difficulties to climb, stalled and crashed. Two passengers were seriously injured while five other occupants were killed.

The seaplane was completing a flight from Wenatchee to Lake Stevens, carrying three passengers and one pilot. While cruising under VFR mode into adverse weather conditions, the airplane struck the slope of a mountain and crashed in the region of Skykomish. SAR operations were initiated but eventually abandoned after few days as no trace of the aircraft nor the four occupants was found. The wreckage was discovered by walkers in an isolated area on July 20, 1979.

En route from Anacortes to Eastsound Airport (Orcas Island), weather conditions deteriorated. Flying at an insufficient height in low ceiling and fog, the single engine airplane struck trees and crashed. The pilot was injured and the airplane was destroyed.

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.

Shortly after takeoff from Vancouver Airport, south Washington, the airplane encountered difficulties to gain height when it stall and crashed in flames. All three occupants were killed.

While flying at low altitude over mountainous terrain, the pilot entered a canyon and was approaching a mountain pass when he elected to gain height. Unable to outclimb the rising terrain, the single engine airplane struck trees and crashed in a wooded area located near Stevens Pass, in the Cascade Mountain Range. The wreckage was found few hours later and all seven occupants were killed.

The pilot started the descent to Seattle-Boeing Field Airport when the left engine failed. The airplane entered a dive, went through the clouds and crashed in flames in Fall City. The pilot, sole on board, was killed.

While approaching Friday harbor, weather conditions worsened with a limited visibility to half of mile due to fog and low ceiling. Unable to locate the runway, the pilot decided to initiate a go-around when he lost control of the airplane that crashed in flames. The aircraft was totally destroyed and all seven occupants have been killed.
