The crew was conducting a test flight after the left engine has been replaced. Few minutes after takeoff, a failure occurred on the 8th cylinder in the left engine and the crew shut off this engine and returned to Hollywood-Lockheed Air Terminal Airport. Due to low visibility caused by foggy conditions, the crew was unable to locate the runway and decided to go around. During the second attempt to land, the captain decided to reduce his altitude to establish a visual contact with the ground when the aircraft hit an eucalyptus and crashed near Lorne Street, North Hollywood. The aircraft was destroyed by impact forces and a post crash fire and all three crew members were killed.

After takeoff from Oakland Airport, while climbing, the crew was instructed by ATC to maintain a minimum safe altitude of 3,000 feet or at least 500 feet above clouds. Shortly later, due to the deterioration of the weather conditions, the captain informed ground that he elected to return to Oakland Airfield. While completing a last turn to the right at an insufficient altitude, the twin engine aircraft hit tree tops then crashed in a wooded area located on the slope of Mt Diablo located east of Walnut Creek. The aircraft was destroyed by impact forces and both occupants were killed. At the time of the accident, the mountain was shrouded by clouds and the visibility was poor.

While cruising by night, the aircraft hit the slope of a mountain located 21 km southeast of Albuquerque. All 11 occupants were killed.

The flight was cleared to Washington National Airport by the Washington control tower and Instructed to use Runway 21 However, because it had been necessary to bear to the left when northeast of the airport to a position from which approach to Runway 21 was, not practicable, the flight was asked by Washington Tower if it desired to use a right-hand. Pattern for Runway 36 The flight replied that it desired clearance for Runway 27, and, as the wind was calm, Washington Tower approved this request. The flight approached the field from the northeast and while over the east bank of the Potomac River approximately 2/3 of a mile from the boundary of the airport, turned to the right and started a descent in final approach to Runway 27. According to the testimony of the pilots, Initial contact was made with the runway between 800 and 1,000 feet from the approach end and the aircraft continued down the runway with less than normal deceleration, Approximately 600 feet from the far end of the runway the pilot attempted a turn to the right. After turning approximately 30 degrees, the aircraft rolled beyond the runway end and struck a concrete transformer housing. The aircraft whipped approximately 90 degrees to the right and came to rest across a drainage ditch with its empennage extending over the highway which adjoins the airport. All twelve occupants were evacuated safely while the aircraft was damaged beyond repair.

While flying at an altitude of 7,200 feet, the twin engine aircraft lost a part of its right wing and the empennage failed as well. Out of control, the aircraft dove into the ground, partially disintegrated in the air and eventually crashed on the slope of a mountain located in the Donner State Park, west of Hobart Mills. All 26 occupants were killed.

At 0559LT, the aircraft departed Tucson and routine position reports were subsequently received from the flight over Casa Grande, Gila Bend, and Yuma, Arizona. At 0754, the American Airlines radio operator at San Diego transmitted the 0750 weather report for San Diego: Indefinite ceiling 1,200 feet, broken clouds; visibility 8 miles. Receipt of this information was acknowledged by flight 6103 and immediately thereafter the flight reported that it had been over El Centro, California, at 0753 at 3,000 feet. Los angels Airway Traffic Control delivered a clearance for Flight 6103 to American Airlines radio station at San Diego clearing the flight to San Diego to cruise at 8,000 feet and to cross San Diego at an altitude of at least 500 feet above the overcast. The company station, in turn, attempted to relay the Airway Traffic Control clearance to the flight at 0812, however, after several attempts at establishing contact with the flight, Airway Traffic Control was advised that the clearance as not delivered. All further attempts to contact the flight were unsuccessful. Routine search procedures were initiated immediately and at 1305 aircraft of the Naval Air Control Center at San Diego reported sighting the wreckage of the airplane was spotted on the east slope of Thing Mountain, some 10 miles southeast of Pine Valley. The aircraft was destroyed by impact forces and all 25 occupants were killed.

Following several modifications, the aircraft was completing a test flight for a CAA certification and was carrying a NAA research engineer, one pilot and a CAA inspector. After its departure from Los Angeles-Mine Field, the twin engine aircraft flew to the northwest when an engine caught fire in flight. Out of control, the aircraft dove into the sea and crashed few miles off Malibu. All three occupants were killed.

Crashed on takeoff in unknown circumstances. Both crew were unhurt while the aircraft was damaged beyond repair.

On the non stop leg from Boise to Denver, while flying by night and poor visibility, the aircraft hit the slope of Mt Elk located southeast of Elk Mountain, south Wyoming. The wreckage was found few hours later in a deep snow and in poor weather conditions, about 340 feet from the summit. The aircraft was destroyed by impact forces and all 21 occupants were killed. At the time of the accident, the aircraft deviated from the prescribed flight path by 4,5 miles and its altitude was 11,000 feet.

About thirty minutes into the flight, a fire erupted in the left engine. The crew was unable to extinguish the fire that spread quickly to the entire engine and nacelle that detached, causing the wing to partially collapse. The aircraft went out of control, dove into the ground and crashed in flames in a field located in Cheshire. All 17 occupants were killed.
