Houston

While on a night approach to Augusta-Bush Field Airport, the pilot encountered marginal weather conditions. On final, the twin engine airplane struck the ground and crashed few dozen yards short of runway threshold. The aircraft was destroyed and the pilot was killed.

En route from Las Vegas to Houston, the left engine failed. The pilot was able to feather the propeller but unable to maintain a safe altitude. He informed ATC about his situation and was cleared to divert to the nearest airport for an emergency landing. While trying to land at a ranch airstrip, the airplane hit a wood pile and crashed in flamers. The pilot and a passenger were seriously injured while four other occupants were killed.

Braniff Flight 352 departed Houston (HOU) at 16:11 for a flight to Dallas (DAL) and climbed to FL200. Some 25 minutes into the flight, the L-188A Electra was approaching an area of severe thunderstorm activity. The crew requested a descent to FL150 and a deviation to the west. ARTCC then advised the crew that other aircraft were deviating to the east. The Electra crew still thought it looked all right on the west and were cleared to descend to FL140 and deviate to the west. At 16:44 the flight was further cleared to descend to 5000 feet. At 16:47 the aircraft had apparently encountered an area of bad weather, including hail, and requested (and were cleared for) a 180° turn. Subsequent to the initiation of a right turn, the aircraft was upset. During the upset, N9707C rolled to the right to a bank angle in excess of 90° and pitched nose-down to approximately 40 degrees. A roll recovery maneuver was initiated and the aircraft experienced forces of 4,35 g. Part of the right wing failed and the aircraft broke up at an altitude of 6750 feet and crashed in flames a little later. There was no survivor among the 85 occupants.

After takeoff, while in initial climb, one of the engine failed. The pilot reduced his altitude and attempted an emergency landing. The airplane belly landed in a field and came to rest in flames. All four occupants escaped uninjured while the airplane owned by George J. Darneille was destroyed by fire.

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.

The flight departed Minneapolis, Minnesota, at 0746LT, bound for Houston, Texas, via schedules intermediate points. A crew change was made at Kansas City, Missouri, and no mechanical discrepancies were reported by the incoming crew with the exception that the left engine torque meter pressure indication was approximately 90 FSI, the normal being approximately 145 PSI The flight departed Kansas City and proceeded in a routine manner to Tulsa, arriving at 1244. The left engine, torque meter pressure indicator was considered inoperative because of its low reading, and was, therefore, disregarded during the flight 2. Following touchdown at Tulsa, the propellers were placed in reverse thrust, and when being returned to positive thrust, the left propeller went to the full feathered position and the engine ceased operation. While taxiing to the loading ramp, attempts were made to start the left engine but were not successful. On departure from Tulsa, no difficulty was encountered in starting the left engine, and the propeller which was in the full feathered position was returned to the low pitch position by use of the propeller governor control. Take-off was accomplished from Tulsa at 1302LT, with 29 passengers, including one infant, and a flight crew consisting of Paul C. Walters, captain, Forrest A. Hull, copilot, Cecelia Littell and loan Stoltenberg, the two stewardesses. Total aircraft weight was 40,304 pounds, which was within the allowable gross weight of 40,500 pounds, and the load was distributed so that the center of gravity was within the certificated limits. Prior to take-off, the engines were run up and the pre-flight check accomplished using a check list. All items checked satisfactorily, with the exception that the left engine torque meter pressure indicator was abnormally low. Flaps were positioned at 24 degrees for take-off. The take-of roll was started on Runway 12, and the signal devices in the cockpit indicated that the automatic feathering unit and the anti-detonation injection unit were functioning. During the take-off roll, the copilot called out the following indicated air speeds. VMC, 107 miles per hour, V1, 121 miles per hour, and V2, 122 miles per hour. The aircraft became airborne at 124 miles per hour, or slightly higher. The landing gear was immediately retracted and the air speed was then observed to be 145 miles per hour at this time, at an altitude estimated to be not over 50 feet, the left propeller was observed to feather and then immediately to rotate slowly. It continued to rotate until the aircraft struck the ground. The crew first became aware that the left engine was malfunctioning when a severe vibration was felt immediately after the gear had been retracted and at the same time the aircraft yawed to the left momentarily. Both engine controls were left at the take-off setting, and a single-engine climb was then initiated. The air speed decreased to approximately 124 miles per hour during the climb to a maximum altitude of approximately 150 feet. At this point, since it was doubtful that this air speed could be maintained, the aircraft was leveled off and a shallow turn to the left was made to avoid flying over a building. As the aircraft started turning at an approximate air speed of 122 miles per hour, the captain, according to the copilot, gave the command to retract the flaps from the 24-degree position to the 12-degree position. The copilot states that he immediately executed the command, stopping the retraction of the flaps at 12 degrees. The captain states that he gave the following command, “ 12-degree flaps. No, leave them where they are.” However, the captain testified that the command was given when the air speed was 107 miles per hour and at a point approximately 3000 feet further along the flight path than where the copilot stated he retracted the flaps. While in the left turn, the aircraft was observed to lose altitude steadily until it struck a grove of trees at a point approximately 17 feet above the ground. After striking the trees it slid on the ground on the underside of the fuselage. All passengers and crew were evacuated safely and in an orderly manner. The aircraft was destroyed by fire.

En route from Dallas to Houston, smoke spread into the cockpit, forcing the crew to reduce his altitude and to attempt an emergency landing. The aircraft crash landed in an open field located in Ferris, some 30 km south of Dallas, bursting into flames. All six occupants were rescued, among them both crew members Ed Hefley and Eugene Schacher were seriously injured by fire.

Crashed in unknown circumstances. The pilot, sole on board, was killed.
