Circumstances:
The aircraft crashed on runway 16 at Dyess AFB, Abilene, Texas. The crash occurred while the pilots were attempting to land the aircraft with the elevator controls inoperative. The captain and copilot, the only persons aboard, were killed. The aircraft was demolished. Examination of the longitudinal control system of the aircraft disclosed that the aft end of the aft link assembly was disconnected from the clevis in the elevator control horn assembly. This condition would render the elevator control inoperative. From irrefutable physical evidence the Board concludes that the bolt which normally secures the link assembly-clevis attachment was not in place at impact. It concludes that the bolt worked out following departure from Dyess AFB, resulting in the loss of control which caused the accident. The Board further concludes that the bolt worked out because it was improperly secured, a condition which should have been detected during a No. 2 maintenance inspection completed just prior to the origination of Trip 7002. The inspection was performed by Associated Airmotive., Inc., a certificated repair station which performed under contract the maintenance work for AAXICO.
Probable cause:
The Board determines that the probable cause of this accident was loss of elevator control because of an improperly secured bolt, a condition which was undetected because of an inadequate inspection.

Circumstances:
The aircraft departed Kotzebue for McGrath, both in Alaksa, at 1315 A.s.t., with nonrefueling stops at Kiana and Tanana. At Tanana Pilot Chefley W. Priest was briefed on en route weather to McGrath as well as on the route and terminal forecasts. He departed Tanana at 1957LT, about an hour before sunset, on a VFR flight plan. An emergency distress call from the aircraft was first heard at 2126LT. There followed several communications between the Beechcraft and the McGrath ground station which issued navigational advice. At or about 2214LT approximately three-quarters of an hour after dark and during rain showers, the aircraft struck the ground violently in a steep spiral at a point about 26 miles from the McGrath Airport. This accident appears to have been caused by the pilot's loss of control during instrument flight and his failure to recover. All eight occupants were killed.
Probable cause:
The Board determines that the probable cause of this accident was the pilot's loss of control while flying under instrument flight conditions, and failure to recover control. Contributing factors were poor flight planning, possible fuel exhaustion, and the pilot's lack of instrument proficiency.

Circumstances:
The crew was completing a local training flight at Calverton-Peconic River Airport, Long Island, New York. While approaching runway 23 at an altitude of 1,000 feet, the airplane yawed to the right, stalled and crashed in a field located three miles from the airport. The airplane disintegrated on impact and all five crew members were killed.
Probable cause:
The Board determines the probable cause of this accident was the crew's failure to recognize and correct the development of excessive yaw which caused an unintentional rolling maneuver at an altitude too low to permit complete recovery.

Circumstances:
While on a training mission from Westover AFB, the crew encountered technical problems after the radome detached in flight. The captain elected to divert to the nearest airport but due to poor weather conditions, ATC vectored the crew to Goose Bay, about 860 miles northeast of his position. As he could not make it, the crew decided to bail out and abandoned the aircraft that dove into the ground and crashed in the Spruce swamp located near Fremont. The aircraft disintegrated on impact and all eight crew members were later found uninjured.

Probable cause:
The Air Force Accident Investigation Board determined after a thorough investigation that the cause of the crash was due to a loss of lubrication to the bearings in the #4 engine turbo supercharger. That led to a failure of the turbo supercharger shaft. The turbine, once unloaded, accelerated to destruction and caused the uncontained catastrophic fire, due to what would presumably have been severed fuel lines or punctured tanks in the wing.

Circumstances:
The purpose of this flight was to transport the executives from Midway Airport, Chicago, Illinois, to Baltimore, Maryland. Departure from Midway was at 1645LT. When the flight was near Marion, Ohio, and shortly after it had traversed an area of pronounced thunderstorm activity, it dived violently and nearly vertically to the ground. Destruction was of such extent that it could not be determined if a structural failure occurred in flight and consequently the probable cause of this accident could not be established.
Probable cause:
The Board is unable to determine the probable cause of this accident. However, circumstances suggest control difficulty of an undetermined nature during passage through an active developing line of thunderstorms.

Circumstances:
At 11:05 a.m. on Tuesday, June 23, 1959, Tommy’s Tigator took off from Boeing Field for an experimental low-level flight test. Five employees of the Boeing Airplane Company were on board the B-52D: Lewis E. Moore, commander/pilot; Joseph Q. Keller, copilot; Gerald G. Green, navigator; Charles K. McDaniel and Neil Johnson, flight-test engineers. The aircraft had been making test runs over Eastern Washington, Oregon, and Idaho since April 10, 1959, and was loaded with special electronic equipment for measuring stresses on the airframe and flight surfaces. The bomber was scheduled to fly at lower than 500 feet above the ground on an elliptical course from The Dalles, Oregon, to Malheur Lake, Burns, and back to Walla Walla, Washington, at near maximum speed of 638 miles-per-hour. At 11:30 a.m., Tommy’s Tigator radioed that it was over The Dalles and preparing to descend for the low-level test flight. No further reports were heard from the pilot after it passed the checkpoint. Leslie Heinz, a lineman for the Harney County Rural Electric Cooperative, was an eyewitness to the accident. He was working with a crew on power lines in a remote area approximately 35 miles west of Burns and three miles from the crash site. At about 12:00 noon, he spotted the B-52 flying southeast approximately 300 feet above the desert floor when it suddenly crashed. The aircraft disintegrated on impact and all five crew members were killed:
Crew:
Lewis E. Moore, pilot,
Joseph Quentin Keller, copilot,
Gerald G. Green, navigator,
Neil Johnson, flight engineer,
Charles Kenneth McDaniel, flight engineer.
Source: http://www.historylink.org/File/10063
Probable cause:
The investigation by Air Force and Boeing experts concluded the accident was caused by the catastrophic failure of the horizontal stabilizer (tail plane), affecting the B-52’s longitudinal stability. The plane was not designed for the excessive turbulence of high-speed, low-level flight and began to disintegrate. Minus the horizontal stabilizer, the nose of the plane pitched sharply upward and it stalled, struck a knoll and exploded. At an altitude of 500 feet, there was virtually no chance for the crew to escape.
