The aircraft departed the airport in IFR conditions (snowing) and was observed staggering into the air. Shortly after takeoff the aircraft struck power lines and crashed into homes in a residential area. Investigation revealed that the aircraft had accumulated ice and in addition was over certified max gross weight. There was no evidence of airframe, flight control or engine failure/malfunction prior to impact with the power lines.

Approximately 7 minutes after takeoff (at 1441), the pilot declared an emergency and said the left engine had lost power. He feathered the engine, diverted back toward the airport and descended to VFR conditions below the clouds. At 1448, the pilot said he had the airport in sight and turned onto a left downwind for runway 15. Reportedly, he extended the landing gear and began a left turn toward the runway. Reportedly, the aircraft was too close in and/or the pilot chose to make a right turn away from the airport to land. Witnesses lost sight of the aircraft during the turn due to low clouds or obstructions. The pilot lost sight of the airport for a short time, then relocated it, but said he had his 'hands full.' Shortly thereafter, the aircraft entered a steep descent, hit the edge (roof) of a building, crashed into a utility pole and the ground and burned. There was evidence the aircraft was inverted just before impact. An exam of the left engine revealed evidence the #6 connecting rod had failed from oil exhaustion. Only one cup of oil was found in the engine and it had a history of high oil consumption. The pilot, sole on board, was killed.

On final approach about 1.5 miles from the airport the power loss occurred as the pilot attempted to add power. After flying over a ridge and several trees the aircraft touched down in the rough terrain and caught fire. The fire appeared to have started in the vicinity of the fuel strainer and progressed rearward. There were no indications of fire until the aircraft came to rest. The only discrepancy noted during inspection of the aircraft and engine was that 3 left bank fuel injectors were blocked with a substance later identified as primarily being dirt. Both occupants escaped unhurt.

The crew departed Fairchild AFB, WA, on a training mission. While cruising by night, the crew encountered an unexpected situation (unknown technical problems) and decided to abandon the aircraft that crashed in a canyon located in Hunts Mesa, about 13 miles northeast of Kayenta, AZ. Two crew members were killed while five others were rescued. The aircraft disintegrated on impact.

Aerial photos were being taken of the mishap aircraft. Mission called for a simulated water landing (actual water landing prohibited) by flying as close as possible to water. Copilot at controls descended aircraft to about 6 feet, then gradually reduced clearance to 6-12 inches above water, airspeed 105 mph. Copilot inadvertently allowed aircraft to touch water. On touchdown, aircraft decelerated violently and broke up, ejecting several of the occupants and coming to rest inverted. Examination of aerial photos shows aircraft hull at touchdown was slightly nose down vice normal landing attitude; water contact made at location of nose landing gear doors. Photos show outward rupturing of forward hull structure, nose gear doors missing. Hull at rear of step showed two parallel, 3-feet long by 2-in wide, fore-to-aft and outboard-to-inboard penetrations. Floor of shallow lagoon known to have scattered debris from petroleum explorations; however, no positive determination of aircraft contact with submerged object could be made. Seven occupants were killed while three others were injured.

The pilot allowed the aircraft to stall at an altitude which was too low to effect recovery before ground impact occurred. He was in the process of performing VMC test and maximum performance single engine climbs during the test flight. Witness description of the aircrafts movements at the beginning of the accident sequence suggests that the VMC test were in progress immediately before the accident occurred. Both occupants were killed.

The aircraft, a Gates Learjet 24B, modified by a Howard/Raisebach Mark II conversion, was cleared for takeoff on runway 28L. Tower personnel estimated that the aircraft rotated for takeoff at 3,200 feet down the runway and was at approximately 200 feet agl when the pilot was instructed to contact departure control. Witnesses observed the aircraft climbing in a wings level attitude when it entered the broken cloud layer at about 600 feet agl. Moments later, the aircraft was observed descending out of the clouds at a steep angle and in a left wing low/nose down attitude. The aircraft impacted between runway 28L and 28R, approximately 10,000 feet from the approach ends. Witnesses reported that the engines sounded like they were operating at a high power setting. An exam of the engines revealed evidence that both were at or above 92% power at impact. No preimpact part failure/malfunction was found. Records revealed two autopilot discrepancies on 10/4/84; one induced the roll mode was sensitive; the other induced the autopilot intermittently rolled the aircraft into a standard rate left bank when engaged. Reportedly, the autopilot would not have been used for takeoff. All three occupants were killed.

The Hansa Jet HFB-320 aircraft crashed on takeoff from the Aberdeen Airport after the flight crew selected the incorrect runway for takeoff. The aircraft was observed running off the end of runway 17, which is 3,860 feet long, where it struck a fence, ditch, road and another ditch then became airborne, the landing gear separated during the above sequence. The aircraft was than observed to level off momentarily, then descend in a right turn until impact. Investigation revealed the crew had been flying 12 hours except for refueling stops and cargo loading. In addition, calculations revealed the aircraft was over gross weight by approx 1 ton. The proper runway for takeoff was 13 (40° chance) and 6,900 feet long. Runway used was restricted to aircraft less than 12,500 gto weight. N127MW weighed over 20,000 lbs. All three occupants were killed.

The aircraft was flying at a very low altitude over mountainous terrain. As the aircraft approached a crest of a ridge the aircraft started to buffet and then encountered a downslope wind condition. The combination of approaching a stall and encountering a downdraft forced the aircraft into trees. The pilot, sole on board, was killed.

Flight departed in instrument meteorological conditions. After departure pilot failed to maintain assigned headings several times and had to be corrected by ATC. After 15 minutes of flight the pilot reported he was having problems with the right engine and would like to return to the airport. ATC advised the pilot that Craig Airport was available and was currently reporting VFR conditions. Pilot stated he wanted to go to Jax int'l because the 4,000 feet runway at Craig was not long enough. Jax int'l was reporting IFR conditions. The pilot continued to have trouble holding headings while being vectored for an ILS approach. While in the downwind position for the approach the pilot asked ATC, 'how far is 982 from landing?'. As the aircraft was turned onto the localizer the pilot called and stated he had lost control and was in a spin. Post crash inspection of the right engine revealed the #5 cylinder had detonated until a hole was burned in the piston. Additionally the #5 and #6 rods had burn damage and the #6 rod bolts had failed in overload. The pilot was killed and both passengers were injured.
