Narrative:
Azul Linhas Aéreas Flight AD2520 departed Belo Horizonte, Brazil at 07:50, bound for Vitória.
During the descent to Vitória, at approximately 14,000ft, there was a short circuit with overheating and spark emission inside the aircraft, on the side left of front fuselage, near seat 03A. A fire extinguisher was used to contain the sparks. The pilot declared a condition of urgency and asked for priority for landing. A normal landing was carried out at Vitória Airport at 08:58 hours.

Contributing factors.
- Manufacturing - undetermined.
The manufacturer established requirements for the installation of the wiring in order to avoid friction between its elements. However, it was observed that the short circuit occurred due to the contact between conductor wires, which lost insulation material due to friction between the wiring and the reverse side of the sidewall.
Worn wiring was found in other sections in the same aircraft, as well as in two other aircraft produced in the same context. Thus, it is possible to consider that there has not been full adherence, by the assembly personnel, to the requirements established by the manufacturer.
