Circumstances:
The pilot, sole on board, departed Kansas City on a delivery flight to Honolulu with an intermediate stop in Los Angeles. While cruising by night over the Pacific Ocean, the pilot declared an emergency and reported his position about 646 miles northeast from the Oahu Island. SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the pilot was found.
Probable cause:
Inadequate preflight preparation on part of the pilot. Engine failure in flight caused by a lubricating issue and oil exhaustion. No prove was made for extra oil, engine lost oil pressure then failed.

Circumstances:
Prior to takeoff, the local controller offered pilot choice of runways 01 or 28. The crew decided to takeoff from runway 01. During the takeoff roll, the airplane was caught by strong winds and control was lost. The airplane veered off runway, lost its undercarriage and came to rest in flames. Both pilots were injured and the aircraft was destroyed by fire.
Probable cause:
The crew selected the wrong runway relative to existing wind. The following factors were considered as contributing:
- Unfavorable wind component,
- Inadequate preflight preparation,
- Improperly loaded aircraft (W&B and CofG),
- Overload failure,
- Wind gusting up to 23 knots,
- Aircraft loaded aft of CofG.

Circumstances:
Boeing 727-22C N7434U operated Flight 266 from Los Angeles to Denver, CO and Milwaukee, WI. The aircraft had been operating since January 15, 1969, with the No. 3 generator inoperative. This was allowed because according to the Minimum Equipment List, the aircraft is airworthy with only two generators operable provided certain procedures are followed and electrical loads are monitored during flight. Flight 266 was scheduled to depart the gate at 17:55, but was delayed until 18:07 because of the inclement weather and loading problems. The flight commenced its takeoff roll on runway 24 at approximately 18:17. At 18:18:30 the sound of an engine fire warning bell was heard in the cockpit. The crew reported a no. 1 engine fire warning and stated that they wanted to return to the airport. Shortly after shutdown of the No. 1 engine, electrical power from the remaining generator (No. 2) was lost. Following loss of all generator power, the standby electrical system either was not activated or failed to function. Electrical power at a voltage level of approximately 50 volts was restored approximately a minute and a half after loss of the No. 2 generator. The duration of this power restoration was just 9 to 15 seconds. The Boeing descended and struck the sea 11.3 miles west of the airport. The ocean depth at this point is approximately 950 feet.
Probable cause:
The loss of attitude orientation during a night, instrument departure in which all attitude instruments were disabled by loss of electrical power. The Board has been unable to determine (a) why all generator power was lost or (b) why the standby electrical power system either was not activated or failed to function.

Circumstances:
The aircraft crashed in Santa Monica Bay, approximately 6 nautical miles west at 1921LT. The aircraft was operating as flight SK933 from Seattle, Washington, to Los Angeles, following a flight from Copenhagen, Denmark. A scheduled crew change occurred at Seattle for the flight to Los Angeles. The accident occurred in the waters of Santa Monica Bay while the crew attempting an instrument approach to runway O7R at Los Angeles International Airport. Of the 45 persons aboard the aircraft, 3 passengers and one cabin attendant drowned, 9 passengers and 2 cabin attendants are missing and presumed dead; 11 passengers and 6 crew members including the captain, the second pilot, and the systems operator, were injured in varying degrees; and 13 passengers escaped without reported injury. The aircraft was destroyed by impact. The fuselage broke into three pieces, two of which sank approximately 350 feet of water. The third section including the wings, the forward cabin and the cockpit, floated for about 20 hours before being towed into shallow water where it sank. This section was later recovered and removed from the water. The weather at Los Angeles International Airport was generally: 1,700 feet broken, 3,500 feet overcast; visibility 4 miles in light rain and fog, wind 060° at 10 knots; and the altimeter setting was 29.87 inches of mercury. The weather in the accident area was reported to be similar.
Probable cause:
The lack of crew coordination and the inadequate monitoring of the aircraft position in space during a critical phase of an instrument approach which resulted in an unplanned descent into the water. Contributing to this unplanned descent was an apparent unsafe landing gear condition induced by the design of the landing gear indicator lights, and the omission of the minimum crossing altitude at an approach fix depicted on the approach chart.

Circumstances:
Following an uneventful flight from Los Angeles, the crew started the descent to Santa Ana Airport when he encountered poor visibility due low clouds and fog. On short final, the crew failed to realize his altitude was insufficient when the airplane struck a 30 feet steel light pole located along the Costa Mesa Freeway. Out of control, the airplane dove into the ground and crashed in flames 1,8 mile short of runway 20R threshold. The aircraft was totally destroyed and none of the nine occupants survived the crash.
Probable cause:
The accident was probably caused by the combination of the following factors:
- Improper IFR operation,
- The pilot-in-command misjudged altitude,
- Low ceiling and foggy conditions,
- Visibility limited to 3/4 mile or less.

Circumstances:
TWA Flight 159 was a scheduled domestic flight from New York to Los Angeles with an intermediate stop at the Greater Cincinnati Airport. It departed the ramp at Cincinnati at 1833 hours Eastern Standard Time. As it was approaching runway 27L for take-off, Delta Air Lines, Inc., DC-9, N-3317L, operating as Flight DAL 379, was landing. As DAL 379 was completing its landing roll, the crew requested and received clearance for a 180° turnaround on the runway in order to return to the intersection of runway 18-36 which they had just passed. After turning through approximately 90°, the nosewheel slipped off the paved surface and the aircraft moved straight ahead off the runway during which time it became mired. The throttles were retarded to idle, and power was not increased again. At 1839:05 hours as DAL 379 was in the process of clearing the runway, TWA 159 was cleared for take-off. The local controller testified that before TWA 159 began moving, he observed that DAL 379 had stopped. He stated that although DAL 379 appeared to be clear of the runway, he requested confirmation from the crew who replied, "Yeah, we're in the dirt, though." Following this report the controller stated "TWA 159 he's clear of the runway, cleared for take-off, company jet on final behind you." Take- off performance had been computed as V1 132 knots, VR 140 knots, V2 150 knots. In fact DAL 379 was stopped on a heading of 004' and located 4 600 ft from the threshold of runway 27L with its aft-most point being approximately 7 ft north of the runway edge, the aft-most exterior lights located on the wing tip and the upper and lower anti-collision lights being approximately 45 ft from the runway edge. The crew of TWA 159 did not have DAL 379 in sight when they commenced the take-off roll. The co-pilot was performing the take-off and the pilot-in-command drew his attention to DAL 379 as the aircraft appeared in their landing lights they could see that it was off the runway by Some 5-7 ft. As TWA 159 passed abeam of DAL 379 the co-pilot experienced a movement of the flight controls and the aircraft yawed. Simultaneously there was a loud bang from the right side of the aircraft. The last airspeed he had observed was 120 knots and assuming that the aircraft was at or near V1, and that a collision had occurred, he elected to abort the take-off . He stated that he closed the power levers, placed them in full reverse, applied maximum braking, and called for the spoilers which the pilot-in-command operated. Directional control was maintained but the aircraft ran off the end of the runway, rolled across the terrain for approximately 225 ft, to the brow of a hill, and became airborne momentarily. It next contacted the ground approximately 67 ft further down the embankment, the main landing gear was torn off and the nosewheel was displaced rearward, forcing the cabin floor upward by approximately 15 in. The aircraft slid down the embankment and came to rest on a road approximately 421 ft from the end of the runway. The accident occurred at approximately 1841 hours, in darkness. A passenger was killed, another was seriously injured, five others were slightly injured. The aircraft was written off.
Probable cause:
The Board determined that the probable cause of the accident was the inability of the TWA crew to abort successfully their take-off at the speed attained prior to the attempted abort. The abort was understandably initiated because of the co-pilot's belief that his plane had collided with a Delta aircraft stopped just off the runway. A contributing factor was the action of the Delta crew in advising the tower that their plane was clear of the runway without carefully ascertaining the facts, and when in fact their aircraft was not at a safe distance under the circumstance of another aircraft taking off on that runway.

Circumstances:
The aircraft made a "firm" landing, in heavy rain, about 1,050 feet past the approach end of runway 18. When the crew's efforts to stop the aircraft were ineffective, and the captain was convinced that they were going off the end of the runway, he used differential power and rudder to cock the aircraft to the left. The aircraft slid off the end of the runway, went through the US localizer antenna building, struck a dirt blast mound, slid up over the mound, and came to rest with the nose section in the perimeter road between the blast mound and a river levee. Of the 60 passengers and 6 crew members aboard, three passengers and two crew members received minor injuries. The aircraft received substantial damage although no major fire occurred. The passengers and crew evacuated the aircraft without major difficulty.
Probable cause:
The Board determines that the probable cause of this accident was hydroplaning of the landing gear wheels that precluded braking effectiveness.

At 05:54 PST the pilot reported a bad fire in the no. 2 engine and stated that a ditching might become necessary. Nothing more was heard from the flight. Extensive search efforts were discontinued after 5 days; nothing had been found. A total of 15-17 min maintenance delay had occurred on the Los Angeles-Philippines round trip. Among the causes of these delays was a recurring oil leak in the propeller governor assembly for the no. 2 engine.
Probable cause:
In-flight No.2 engine fire for an undetermined cause, resulting in ditching at sea.
