Circumstances:
The crew was performing a positioning flight from Austin-Bergstrom Airport to LBJ Ranch to pick up Lyndon B. Johnson. vice-president of the United States. En route, the crew was informed about weather conditions at destination with low clouds and low visibility due to rain falls. While approaching the ranch under VFR mode, the pilot was unable to locate the runway due to lack of visibility (night and rain) and decided to return to Austin when the airplane struck the ground and crashed. Both pilots were killed.

Circumstances:
En route from San Antonio to Mobile at an altitude of 2,500 feet, the crew informed ATC that the left engine caught fire. He elected to divert to the nearest airport but few minutes later, the left wing detached and the airplane crashed in flames in a field located in Katy, about 27 miles west of Houston. The aircraft was destroyed and both pilots were killed.
Probable cause:
It was determined that the 8th cylinder on the left engine failed in flight, causing hydraulic leak. The oil spread in the engine nacelle and caught fire while contacting high temperature equipment. As the fire could not be contained, it spread to the left wing which detached shortly later.

Circumstances:
Flight 542 departed the ramp at Houston at 2237LT, 22 minutes behind schedule with a total of 34 persons including a crew of six consisting of Captain Wilson Elza Stone, First Officer Dan Hollowell, Second Officer Roland Longhill, and Stewardesses Alvilyn Harrison, Betty Rusch and Leona Winkler, none of whom survived. The delayed departure was due to a mechanical discrepancy involving No. 3 generator. This generator was inoperative on arrival of N9705C at Houston. Prior to departure from Houston the Nos. 3 and 4 voltage regulators were interchanged. Actual gross weight upon departure was calculated at 83,252 pounds, including 17,000 pounds of fuel, and was 16,548 pounds less than the authorized gross weight of 99,800 pounds. The estimated time en route to Dallas was 41 minutes. The flight was given an instrument-flight-rules clearance which was to the Leona omni, via Victor Airway 13 west to the Gulf Coast intersection, direct to Leona, to maintain 2,300 feet altitude to Gulf Coast, then to climb to and maintain 9,000. At approximately 2240 the flight was cleared for takeoff and at 2242 it reported ready for takeoff and was airborne at 2244. After takeoff Houston departure control advised that it had the flight in radar contact and requested it to report when established outbound on the 345-degree radial of the Houston omni. Flight 542 complied and subsequently was cleared to 9,000 feet and advised to contact San Antonio Center on 121.1 mcs. upon passing the Gulf Coast intersection. Flight 542 reported to company radio at 2251 as blocking out of Houston at 37, taking off at 42, to cruise at 15,000 feet when so cleared, estimating Dallas at 2325, and that the Center had this information. At approximately 2252 Flight 542 reported to San Antonio Center as being over Gulf Coast intersection at 9,000 feet. The flight was then issued its destination clearance to the Dallas Airport via direct to Leona, direct to Trinidad, direct to Forney, direct to Dallas, to maintain 15,000 feet. The flight was cleared to climb to its cruising altitude. The next transmission from Flight 542 was to the San Antonio, Center, giving the time over Leona as 05 at 15,000. San Antonio Center acknowledged, and requested Flight 542 to change over and monitor the Fort Worth frequency of 120.8 mcs. at this time. The flight acknowledged. Shortly thereafter Flight 542 contacted company radio with a message for maintenance, advising that the generators were then OK out that there had been insufficient time for maintenance to insulate the terminal strip on No. 3 propeller at Houston and it would like to have it done in Dallas. At this time the flight also said it would give the communication center a Dallas estimate of 25. This was then followed by one other item for maintenance, which was that No. 3 sump pump was inoperative. This was the final transmission from the flight and was logged as completed at 2307. Structural failure of the aircraft occurred at approximately 2309 on course to the next fix, Trinidad intersection. The radial from Leona omni to Trinidad intersection is 344 degrees. The main wreckage was located 19.7 miles 2 north of Leona omni, 3.19 miles east-southeast of Buffalo, Texas. The time, 2309, correlates closely with the information obtained from witnesses to the accident as well as the time indicated on impact-stopped watches recovered at the scene. The aircraft was destroyed upon impact and all 34 occupants were killed.
Probable cause:
The Board determines that the probable cause of this accident was structural failure of the left wing resulting from forces generated by undampened propeller whirl mode.

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 crew departed Bergstrom AFB (Austin) on a B-52 refuelling mission. En route, while cruising in a low pressure area with turbulences, the airplane went out of control, dove into the ground and crashed in a huge explosion. All four crew members were killed. Brand new, the airplane has been delivered six weeks prior to the accident.
Crew:
Lt Rodney Anderlitch,
Maj Jesse Lee Myrick,
Lt Philip Camillo de Bonis,
Sgt Herman Allison Clark.
Probable cause:
Following severe turbulences in-flight, the pylon of two engines failed, causing the engine to detach. One of them struck the empennage that was partially sheared off. The aircraft went out of control and crashed.

Circumstances:
A General Airways DC-3 crashed shortly before midnight near Kerrville, Texas, on February 1, 1959, during a civil air movement (CAM) of 25 military personnel from Boise, Idaho, to Lackland Air Force Base (Kelly AFB), San Antonio, Texas. Three of the 28 occupants, including the captain and the reserve captain, then acting as copilot, were killed, four were seriously injured, and 21 received minor injuries. The final segment of the flight was from Pueblo, Colorado, where the U. S. Weather Bureau Station furnished weather briefing. Icing prevailed and was to continue. An IFR flight plan specifying cruising at 9,000 feet was filed. Departure from Pueblo was at 1800 1 and at 1916 the flight requested an altitude change from 9,000 to 7,000 feet, reporting light icing. ARTC approved at 1945. Shortly thereafter the flight again reported light icing. An involved series of radio contacts ensued as ice accretion became worse, then critical, then incapacitating. A privately used airport at Kerrville, Texas, was staffed and lighted. An attempt to land there failed and the aircraft was crash-landed nearby. Previously alerted fire fighting apparatus and ambulances were sent to the site. Investigation revealed no significant mechanical defect and no unpredicted weather conditions. The Board believes that this accident resulted from the pilot pressing into known and dangerous icing conditions until the aircraft was crash-landed. General Airways, Inc., a CAB certificated supplemental air carrier, surrendered its FAA operating certificate shortly after the accident pending FAA re-evaluation of the carrier's operations. The FAA later restored the certificate.
Probable cause:
The Board determines that the probable cause of this accident was the captain's poor judgment in continuing into known and dangerous icing conditions.

Circumstances:
En route from Sheppard AFB to Carswell AFB, while cruising at an altitude of 6,000 feet in poor weather conditions, the aircraft collided with a USAF Douglas C-124 Globemaster II. Registered 52-0981, the C-124 was en route from Kelly AFB to Tinker AFB with 15 people on board. Following the collision, both aircraft dove into the ground and crashed in a field located near Bridgeport. All 18 occupants on both aircraft were killed.
Probable cause:
It was determined that the collision was the result of an error on part of the C-119's crew who failed to respect the instructions transmitted by ATC, asking them to fly at an altitude of 7,000 feet. For undetermined reason, the crew continue his route at the insufficient altitude of 6,000 feet, crossing the track of the C-124 which was flying at the same level. Low visibility caused by poor weather conditions was considered as a contributing factor.
