Loss of control on final approach due to inadequate maintenance and inspection. The following contributing factors were reported:
- Flight control surfaces: elevator assembly, attachments,
- Binding,
- Loose, part/fitting, missing
- Improper IFR operation,
- Low ceiling,
- Fog,
- Visibility half a mile or less,
- Pivot bolt, P/N AN4-23A found on floor of fuselage,
- Washer and nut missing,
- Destination altimeter setting not obtained.

The flight crew's inadequate and uncoordinated response to the No 2 engine fire warning. The flight engineer failed to correct a gradual power decay on the other engines which occurred while he was retarding the No 2 engine throttle, and the power decay went uncorrected by the pilot and co-pilot. The lack of co-ordination and the lack of corrective action may have been caused by the lack of recent flight crew experience in the L-1049 aircraft. Contributing to the accident was the aircraft's over maximum take-off weight, the crew's use of less than full power for take-off, and the use of less than take-off cowl flaps which precluded adequate engine cooling.

Engine failure on final approach and subsequent collision with trees due to inadequate preflight preparation. The following contributing factors were reported:
- Improper in-flight decisions,
- lack of familiarity with aircraft,
- Mismanagement of fuel,
- Fuel exhaustion,
- Powerplant- instruments: fuel quantity gauge, erratic,
- Complete engine failure both engines,
- Forced landing off airport on land,
- Power schedule pilot used exceeded max structural cruising speed, increasing fuel consumption rate by 100 lbs per hour.

It was determined that the loss of control was the consequence of wake turbulences coming from a preceding Boeing 727 that just took off from the same runway. Uncontrolled collision with ground due to vortex turbulences.

Collision with fence posts after an aborted takeoff for unknown reasons. The following contributing factors were reported:
- Spontaneous improper action,
- Delayed action in aborting takeoff,
- PIlot's decision to abort unknown.

Stall during initial climb due to the failure of the elevator tab control system. It was determined that the elevator swage fitting was binding on bulkhead raceway station 63.

Uncontrolled descent and subsequent uncontrolled collision with ground after the pilot continued flight into known areas of severe turbulences. The following contributing factors were reported:
- Turbulences associated with clouds and thunderstorms,
- Thunderstorm activity.

An attempted take-off with the rudder and right aileron control locks installed, in combination with a rearward centre of gravity, which resulted in the aircraft's rotating to a nose-high attitude immediately after take-off, and entering the region of reversed command from which the pilot was unable to recover. Contributing to the accident was the failure of the flight crew to ensure that the passenger baggage was loaded in accordance with the configuration contained on the load manifest. Their failure resulted in a rearward centre of gravity that was aft of the optimum range, but forward of the rearmost limit.

Collision with power cables due to improper IFR operation. The following contributing factors were reported:
- Fog,
- High obstructions,
- Ground fog,
- Descended below MDA.

Engine propeller tearaway during normal cruise due to nicked blades and fatigue fractures. Separation in flight. Excessive vibrations.
