The Fairchild C-119G airtanker had been dispatched to a fire about six miles west of Castle Crags State Park, California at 17:05 and departed the Siskiyou County Airport, CA (SIY) shortly thereafter. N48076, another airtanker of the same kind, a leadplane, and an air attack arrived at the fire at the same time. Two more airtankers followed shortly thereafter. The leadplane identified the target, the approach and departure routes, indicated the target was at an elevation of 4,500 feet, that the ridge on final approach was to be crossed at 6,600 feet, advised there was no wind, there was good visibility, and that there was no turbulence except a "1.5g bump" going across the head of the fire. The leadplane directed one of the C-119 airtankers to drop first. That airtanker aborted their first run because of excess speed. On the second pass, it crossed the ridge at a different point, permitting a somewhat longer final approach. That drop was a successful one. The run was made through a saddle then down a creek to the fire some two miles down stream with a planned exit down stream into a larger canyon. The leadplane then directed the mishap C-119G airtanker to drop next. The mishap airtanker used the same approach as the first airtanker. The mishap airtanker reached the uphill side of the fire when the crew reported trouble maintaining proper speed and dropped their retardant on the fire. At about the time the pilot dropped the retardant, a structural failure occurred and the right wing separated from the airframe along with the tip of the left wing and the tail booms. The fuselage with both engines and most of the left wing attached encountered terrain impact and burned as a unit.

The airplane was refueled before it departed on the accident flight; the pilot did not supervise the fueling. Shortly after takeoff, the pilot advised the Ontario departure controller that both engines were experiencing a power loss and that he suspected jet fuel contamination. The airplane collided with a berm during the ensuing forced landing. The investigation revealed that the FBO fueled the airplane with 131.3 gallons of Jet A fuel. Investigators did not locate any witnesses who saw the pilot preflight the airplane. The pilot sustained severe head injuries and could not recall if he had preflighted the airplane - the right front seat passenger was not present when the pilot boarded the aircraft.

The pilot began an ILS runway 18R approach at night to the Lakefront Airport. He reported that after the aircraft broke out of the clouds at 1,700 feet, he transitioned to a visual approach. He stated that as he continued, the approach seemed normal, except the VASI lights seemed too far down the runway. He remembered that just before impact, the VASI was providing a red over red indication, but he did not worry as he perceived the aircraft was over the end of the runway and he was about to flare. At about that time, the aircraft impacted with water, well short of the runway. As the aircraft sank, the pilot escaped thru a hole in the windshield. Subsequently, he was found by passing fishermen. The pilot believed he had gotten a false perception of the runway location due to reflection of lights off of calm lake water.

At approximately 3:00 p.m. on September 10, 1987, the Army called Black Hills Aviation to suppress a fire started by a FAADS missile. The missile was fired more than two hours before the crash. A P2V aircraft, Forest Service Number N96271 ["Tanker 07"], owned by Black Hills, was dispatched in response to the request for aerial fire suppression. Tanker 07 was piloted by Nathan Kolb and co-piloted by Woodard Miller, employees of Black Hills Aviation who were not Department of Defense personnel. Tanker 07 obtained authorization to enter the missile range's airspace from the missile range air controller. During the flight, Tanker 07 crashed on the missile range and both pilots were killed. The crash site was located approximately fifteen miles into the interior of the missile range, and was inside the testing site for the FAADS Project.

After leveling at 5,500 feet, the standby power annunciator light illuminated, followed by loss of oil pressure. The pilot turned back toward the airport, but there was a progressive loss of engine power and the prop went to a feathered position. During an emergency landing at night, the aircraft hit a power line and trees, then crashed. During an engine teardown, disassembly of the reduction gearbox scavenge pump revealed that a retaining nut and tang washer (w/i the scavenge pump) had backed off and lodged between the spur gears, which resulted in a sheared scavenge pump drive shaft. In turn, this resulted in the loss of oil pressure and allowed the prop to feather.

The aircraft had been abandoned in the Bahamas for approximately 7 months. A pilot, with no known flight time in a Cessna 421, flew it to Fort Lauderdale. Except to avoid clouds, he made the flight at a low altitude and airspeed. When asked why, he said he was trying to save the engines. The pilot then departed toward an area of dark clouds and thunderstorms. When he did not arrive at the destination, a search was initiated. The aircraft was found 4 days later where it crashed in a steep nose down attitude. Radar data showed the aircraft made several heading changes and was returning to the dep airport before it crashed. The forward part of the aircraft was buried in a swamp, but the aft edges of the wings, fuselage and empennage were visible above water. The props had rotational damages; no preimpact mechanical failure or malfunction was evident. An exam of the right eng revealed its #2 pushrods and rocker arms/shafts/retainers had been removed before flight. Also, a #2 spark plug was stowed with its ignition lead attached. The aircraft owner was not found. The pilot's medical certificate was dated 5/28/85.

A McDonnell Douglas DC-9-82 operating Northwest Airlines flight 255 was destroyed when it crashed onto a road during takeoff from Detroit-Metropolitan Wayne County Airport, Michigan, USA. Just one of the 155 occupants survived the accident. Additionally, Two persons on the ground were killed. Flight NW255 was a regularly scheduled passenger flight between Saginaw, Michigan and Santa Ana, California, with en route stops at Detroit and Phoenix, Arizona. About 18:53, flight 255 departed Saginaw and about 19:42 arrived at its gate at Detroit. About 20:32, flight 255 departed the gate with 149 passengers and 6 crewmembers on board. During the pushback, the flightcrew accomplished the BEFORE (engine) START portion of the airplane checklist, and, at 20:33, they began starting the engines. The flight was then cleared to "taxi via the ramp, hold short of (taxiway) delta and expect runway three center [3C] (for takeoff)..." The ground controller amended the clearance, stating that the flight had to exit the ramp at taxiway Charlie. The crew was requested to change radio frequencies. The first officer repeated the taxi clearance, but he did not repeat the new radio frequency nor did he tune the radio to the new frequency. At 20:37, the captain asked the first officer if they could use runway 3C for takeoff as they had initially expected 21L or 21R. After consulting the Runway Takeoff Weight Chart Manual, the first officer told the captain runway 3C could be used for takeoff. During the taxi out, the captain missed the turnoff at taxiway C. When the first officer contacted ground control, the ground controller redirected them to taxi to runway 3C and again requested that they change radio frequencies. The first officer repeated the new frequency, changed over, and contacted the east ground controller. The east ground controller gave the flight a new taxi route to runway 3C, told them that windshear alerts were in effect, and that the altimeter setting was 29.85 inHg. The flightcrew acknowledged receipt of the information. At 20:42, the local controller cleared flight 255 to taxi into position on runway 3C and to hold. He told the flight there would be a 3-minute delay in order to get the required "in-trail separation behind traffic just departing." At 20:44:04, flight 255 was cleared for takeoff. Engine power began increasing at 20:44:21. The flightcrew could not engage the autothrottle system at first, but, at 20:44:38, they did engage the system, and the first officer called 100 knots at 20:44:45. At 20:44:57, the first officer called "Rotate." Eight seconds later, the stall warning stick shaker activated, accompanied by voice warnings of the supplemental stall recognition system (SSRS). The takeoff warning system indicating that the airplane was not configured properly for takeoff, did not sound at any time prior or during takeoff. After flight 255 became airborne it began rolling to the left and right before the left wing hit a light pole in a rental car lot. After impacting the light pole, flight 255 continued to roll to the left, continued across the car lot, struck a light pole in a second rental car lot, and struck the side wall of the roof of the auto rental facility in the second rental car lot. The airplane continued rolling to the left when it impacted the ground on a road outside the airport boundary. The airplane continued to slide along the road, struck a railroad embankment, and disintegrated as it slid along the ground. Fires erupted in airplane components scattered along the wreckage path. Three occupied vehicles on the road and numerous vacant vehicles in the auto rental parking lot along the airplane's path were destroyed by impact forces and or fire. One passenger, a 4-year-old child was injured seriously.

The flight departed runway 25 at Greenlee County Airport, Clifton, AZ on a VFR flight to Deer Valley Airport, Phoenix, AZ. The pilot and ground witnesses reported that shortly after lift-off, grayish/white smoke emanated from the left engine. The pilot was unable to feather the propeller, circled the airport about 2 times at a low altitude and landed between the runways. The post crash investigation disclosed the fire originated in the vicinity of the left engine turbocharger. The turbocharger oil line housing was found fractured. The housing was missing when the engines were shipped to Teledyne Continental Motors (TCM). The engine crates were opened before safety board investigators arrived at TCM to conduct the engine examination. The left engine exam disclosed external high temp distress and minor detonation signatures.
