The following factors were identified:
- In the individual aspect, there were signs of concern of the crew member with prolonged waiting caused by the local traffic in Fortaleza and by another traffic that was approaching the aerodrome and, because of this, accelerated the procedure of the final approach, descending at high speed and triggering the other operational failures that led to the accident; in the same way, there were signs of excessive self-confidence by the pilot.
- The operator's delay in submitting the requested documentation for the aircraft reduced the credibility of the submitted material. The possibility that the secondary stop was deactivated, despite statements to the contrary by a mechanic, would have been caused by inadequate participation of maintenance personnel in the services performed and by non-compliance with the planned AD.
- There are reports from several pilots about this commander's habits of performing unforeseen procedures, including some that avoided flying with him. It was not researched if the other crew members took this fact to the company's management. The company's response was not researched if it was aware of these operational deviations.
- The pilot misused the resources available in the operation of the aircraft, due to ineffective management of the tasks related to the PF and PNF and the noncompliance with operational rules.
- The PNF did not advise the PF during the approach. The PNF accepted the non-stabilized approach and did not react to reverse the situation.
- The crew made the approach above the glide slope and at high speed; thought inappropriately that it could proceed in those conditions and that there would be ways to reduce the speed and make the landing.
- The crew disobeyed the aircraft's operating rules by performing a destabilized approach outside the envelope recommended by the manufacturer and by placing the power levers below the flight idle position.

Collision with obstacle while approaching under VFR mode in IMC conditions. The following factors were identified:
- The pilot did not have sufficient experience,
- Marginal weather conditions,
- The pilot failed to see and avoid the obstacles and may have suffered a spatial disorientation,
- Excessive workload in the cockpit during the approach associated with lack of visibility, low experience and too many radio communications on the frequency.

The following factors were identified:
- Wrong approach configuration as the aircraft was too high on the glide,
- Poor crew coordination,
- The crew failed to comply with published procedures,
- Poor crew training,
- The crew failed to correct the pitch up attitude during the go-around procedure,
- Lack of visibility due to night, rain and fog.

The exact cause of the engine failure could not be determined with certainty. It is known that engines of this series had problems with gas-dynamic stability, especially at high angle of attack.

The probable cause of the accident, which resulted from the airplane being misloaded to produce a more aft center of gravity and a correspondingly incorrect stabilizer trim setting that precipitated an extreme pitch-up at rotation, was
1) The failure of Fine Air to exercise operational control over the cargo loading process; and
2) The failure of Aeromar to load the airplane as specified by Fine Air.
Contributing to the accident was the failure of the FAA to adequately monitor Fine Airs operational control responsibilities for cargo loading and the failure of the FAA to ensure that known cargo-related deficiencies were corrected at Fine Air.

There is no evidence which permits the investigation to determine with certainty the actual cause of the accident. It is considered a reasonable deduction that the probable cause of the accident was that the aircraft became uncontrollable after hitting high voltage transmission lines due to the aircraft being flown at a low altitude.

Failure of the left engine for unknown reasons.

The accident was the consequence of the following factors:
- Insufficient flight preparation;
- Insufficient fuel supply;
- An emergency landing at night in a densely populated area following a double engine failure as a result of an inappropriate operation of the fuel selector switch.
