Circumstances:
Shortly after takeoff from runway 27 in Oakland Airport, while climbing, left engine failed. Right away, the pilot feathered the propeller and started a right turn when the aircraft stalled and crashed onto a house near the airport. All eight occupants were killed while nobody on the ground was injured.
Probable cause:
According to officials, the failure of the left engine was likely caused by the ruptured of a fuel line.

Circumstances:
In the evening, the crew left McClellan AFB, near Sacramento, on a routine flight to Seattle, Washington. After take off, the pilot completed a circuit over the airport to reach the assigned altitude of 16,500 feet and reduced the engine power to 2,300 RPM. After few minutes, the right engine failed, followed shortly later by the left engine. A crew member was able to bail out before the aircraft went out of control, dove into the ground and crashed in a huge explosion. All five occupants were killed while the sixth was found alive.

Circumstances:
The crew was performing a test flight on this second prototype. Ten minutes after departure from Seattle-Boeing Field, the crew informed ATC that engine n°1 caught fire and attempted to return. At an altitude of 2,400 feet, the pilot feathered the propeller and notified ATC that the fire was spreading quickly. One minute later, as it was about to land, the bomber struck a power line and crashed on an industrial butchery. Extensive emergency resources were dispatched to the scene where rescuers did not find any survivors among the debris scattered over a wide area. The building was destroyed and 34 dead bodies were found: all 11 occupants on board the airplane and 23 people on ground. Thirty people on the ground were injured.
Crew:
Eddie Allen, Chief test pilot by Boeing,
Bob Dansfield, captain.
Probable cause:
A fire on engine n°1 was likely due to the rupture of a supply fuel line. When fuel contacted the engine nacelle and several other components whose temperature was high, a fire erupted that quickly spread across the wing. On final approach, a violent explosion occurred on the left wing when fire contacted the valves of the wing defrost system which was mainly composed of magnesium. In addition, air flowing under the leading edge slats boosted flames significantly, which was considered as a contributory factor. Following this tragedy, Boeing technicians were forced to modify the engine fuel system as well as some others points.

Circumstances:
The twin engine airplane departed Seattle-Boeing Field Airport at 1327LT on an on-demand taxi flight to Annette Island, carrying five passengers and one pilot. While approaching Ketchikan at an altitude of 7,000 feet, the pilot informed ground that the left engine failed. Due to strong winds and marginal weather conditions, it was difficult to control the airplane and maintain a radio contact with ATC. After crossing clouds at an altitude of 2,500 feet, the pilot cut the right engine and attempted an emergency landing when the airplane collided with two tall trees and crashed in hilly terrain some 48 km east of Ketchikan. All six occupants were injured. Two days after the accident, a female passenger died from injuries sustained. The four survivors remained lost for a period of 29 days following the accident, during which time and extensive air, land, and water search was carried on over large areas east and south of Ketchikan and up into British Columbia. After continuing the hazardous search during winter weather for a period of approximately three weeks, the party was given up for lost and the search was abandoned. On February 3, 1943, two of the survivors searching for aid came upon a United States Coast Guard patrol boat in Weasel Cove on Boca de Quadra Inlet and the remaining two were rescued from their camp on February 7, by civilian guides and Coast Guard personnel. The pilot was apparently uninjured in the accident but in an effort to summon aid to his injures passengers he perished by exposure and freezing. His remains were found on February 6, 1943, on the shores of the Boca de Quadra Inlet, some 11 km from the scene of the accident.

Probable cause:
While the stoppage of the left engine from an undetermined cause in extremely rough weather and over hazardous terrain undoubtedly was the primary cause of the accident, it is apparent that strong contributing factors were the pilot's failure:
- To equip himself with an up-to-date aeronautical chart and,
- To utilize the radio aids available to him to accurately establish the position of the flight while on instruments.

Circumstances:
The airplane was completing a night mail flight from Chicago to Seattle with intermediate stops in Minneapolis and Missoula, carrying two pilots and a load of 500 lbs of mail. While overflying west Idaho in poor weather conditions, the twin engine aircraft impacted the slope of a mountain located in the region of Kellogg. The airplane was destroyed by impact forces and both crew members were killed.
Crew:
Joe Livermore, pilot,
Arthur A. Haid, copilot.
Probable cause:
In arriving at a conclusion after an analysis of the evidence, it does not appear that the accident was due to weather, mechanical failure of the aircraft, radio aids or communications, or to any failure of the company to comply with prevailing rules and practices. Full cognizance is taken of the possibility that the magnetic compass may not have been functioning properly during the flight. However, a study of available evidence, this appear improbable. It is the opinion of the Accident Board that the probable cause of this accident was faulty navigation in not following the radio range course upon leaving Missoula and failing to ascent to a safe altitude over the course pursued from Elk River.
