Circumstances:
The four engine airplane departed Kenneth Ingalls Sawyer AFB on a flight to Chicago-O'Hare Airport, carrying 23 passengers and a crew of four. After being cleared to descend from 22,000 feet to 8,000 feet, the crew reduced his speed when at an altitude of 13,700 feet, at a speed of 313 knots, the airplane suffered an in-flight explosion. Both wings detached, all four engines separated as well as the stabs and out of control, the airplane dove into the ground and crashed in an open field located in Greenwood, about 37 miles northwest of Chicago Airport. The aircraft was totally destroyed and all 27 occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. Considered as 'most probable' was an over-pressurization under the cargo floor, an area that houses fuel and other potential sources of ignition. An explosion caused by the ignition of accumulated combustible vapors occurring in that area could, in fact, rapidly propagate to adjacent areas where fuel is present. There was also 'strong evidence' of explosive over-pressures in the forward, aft and upper fuel tank areas. Significantly, investigation showed that were the walls or fittings of the rubber bladder cells containing the volatile liquid to fail, fuel or vapor could be released into the tank cavity and in turn migrate to other part of the aircraft.

Circumstances:
At 1027 the pilot received a weather briefing for Holbrook, AZ. The pilot was told of forecasts for "at least moderate icing in clouds or in precipitation above the freezing level" and the briefer stated "I guarantee you moderate to severe turbulence..." for a route into Holbrook. The pilot later got weather info for Amarillo, TX and filed an IFR flt plan to Amarillo. The aircraft departed at 1150. At 1204 the pilot reported he had an engine problem. Radar plots indicate the aircraft was maintaining a climb of about 500 fpm up to 11,200 ft. Thirty seconds later the aircraft had descended to 8,500 ft. Radio and contact was lost about 1207. Based on a weather study the probable meteorological conditions that existed about the time & in the area of the accident were moderate to severe turbulence below 12,000 ft msl & while in the clouds above freezing level the aircraft likely encountered moderate to severe rime icing. The aircraft was not certificated for flt into known icing conditions. The flight was transporting prisoners for various government agencies.

Circumstances:
After takeoff, the pilot was cleared to proceed on an IFR flight plan. After being cleared to 15,000 ft msl, he reported having trouble maintaining his airspeed and subsequently declared an emergency. Shortly after that, radar contact was lost. The aircraft impacted at night near the top of a mountain ridge at about 4,700 ft msl. The wreckage was demolished and scattered over a large area, but there was no evidence of an inflight breakup. Some parts of the wreckage (including the right engine) were not found on the snow covered terrain. The weather forecast called for: thunderstorms in lines, mountains obscured, moderate and occasionally severe turbulence below 20,000 ft, occasional moderate icing in clouds and in precipitation from the freezing level (3,000 ft) to 20,000 ft. The aircraft was not certified for flight in known icing conditions.

Circumstances:
About 18 minutes after takeoff, the pilot radioed that the n°2 engine had lost power and that he was returning to land at Mcallen. While approaching to land, the aircraft crashed in an open field about 400 yards short of the runway and 115 feet right of the approach lights. During impact, the aircraft was in an inverted attitude, in about a 150 degree right roll and 15 degrees nose down. After impact, an intense fire erupted. An examination of the wreckage revealed no preimpact malfunction or failure except that the right propeller blades were set at 65 degrees. The angle of the blades should have been 86 degrees when in the full feathered position. The aircraft was estimated to be 753 lbs over its maximum gross weight limit at the time of the accident. With the gear down and flaps up, the vmc was calculated to be 92 mph with the propeller windmilling and 87 mph with the propeller feathered.

Circumstances:
The KC-135A aircraft departed Phoenix-Sky Harbor International Airport at 0755 MST for a scheduled 3-hour and 30-minute flight. After completing the navigation leg, the aircraft descended into the Phoenix area for transition at Luke AFB. After completing one TACAN approach at Luke AFB, the KC-135A aircraft was vectored to Phoenix-Sky Harbor International Airport for an ILS touch-and-go landing. The aircraft was then vectored back to the final approach course for a TACAN runway 03 left approach at Luke AFB. The KC-135A aircraft was cleared for the approach to Luke AFB, and after the final approach fix radio call, a midair collision occurred with a Grumman American Yankee civilian aircraft. The empennage of the KC-135A separated, rendering the aircraft incapable of flight and it was destroyed upon ground impact. The Grumman American Yankee aircraft was destroyed during the midair collision. The four crew members in the KC-135A and the two civilians in the Grumman American Yankee were fatalities.
Crew:
LT Col James N. Floor,
Lt Col Ted L. Beam,
Maj Truman R. Young Jr.,
T/Sgt Donald J. Plough.
Probable cause:
The USAF KC-135 was on an IFR flight plan and executing a TACAN 03L approach to Luke AFB. The AA-1 had departed Sky Harbour Airport and had been released by phoenix TRSA. The AA-1 was heading westerly in airspace designated as a special traffic area and was required to have been at or below 2,000 ft msl. A pilot of another aircraft who was trailing the AA-1 stated that a low broken cloud cover was encountered and he had to descend to about 2,000 ft to remain 500 ft below the bases. He stated the pilot of the AA-1 did not descend but appeared to be skimming along in and out of the bases of the clouds. He noticed the KC-135 descending through the cloud deck followed immediately by the collision. The collision occurred about 5 mi south of Luke AFB at an altitude of 2,500 ft msl. The logbook of the AA-1 pilot indicated this was his first trip to the phoenix area. Luke AFB was depicted on the north side of the sectional chart only. VOR airway #16 was split along an e-w line with the northern and southern halves being depicted on each side of the chart.

Occurrence #1: midair collision
Phase of operation: cruise - normal
Findings
1. En route charts - inadequate
2. (c) vfr procedures - improper - pilot in command AA-1
3. (f) lack of familiarity with geographic area - pilot in command AA-1

Circumstances:
At 4,000 feet light icing on the windshield was noted, and the deicing system was activated. After two cycles of deicing, alcohol was smelled in the cockpit, and smoke was coming up from the control yoke. An emergency landing was attempted at Providence, RI, but smoke and flames forced the crew to land on 10-12 inch thick ice on a reservoir. By then, heavy black smoke poured in the cockpit and fire was seen. Upon landing, the left main gear collapsed and the right wing was sheared off. Eleven occupants escaped and were injured while a passenger was killed.
Probable cause:
The deficient design of the isopropyl alcohol windshield washer/deicer system and the inadequate maintenance of the system which resulted in an in-flight fire. The ignition source of the fire was not determined.

Circumstances:
The flight was cleared to maintain 3,000 ft msl until over the airport, then cruise. The pilot had previously stated that he could see the lights on the ground and that he was 15 miles from the airport. At 2013 the pilot stated "we oughta be able to cancel here." The aircraft would have been about 6 mi from the airport. The airport operator heard an aircraft low overhead and was able to see stars. Other ground witnesses closer to the point of impact observed very thick patchy fog with visibility about 200 ft. One witness observed the aircraft navigation lights do some unusual maneuvering, while another witness saw the lights very low. The aircraft impacted the ground in a left wing low, near level flight attitude. The wreckage was co-located with an approximate downwind to base leg turn. There is a single VOR/DME approach to rwy 11. The MDA is 1,260 ft and requires a minimum visibility of 1 mile. The circling approach has an MDA of 1,420 ft and also requires a minimum visibility of 1 mile. The pilot had received an altimeter setting of 29.77. The aircraft's altimeter was set between 30.29 and 30.30.
