Narrative:During an Instrument Landing System approach to São Paulo-Guarulhos International Airport's runway 09R, at 5,500 ft, with the autopilot (AP) engaged, the aircraft tended to maintain the left turn after intercepting the final approach course. The crew disengaged the AP and noticed that the aileron control was not aligned. The left turn tendency remained during the whole approach even with the AP disengaged. The aircraft was sent to maintenance, where the personnel found the release of the AP servo actuator cable (pn 7002260-722).

- Project – undetermined.
Considering that all records related to scheduled maintenance and scheduled checks for the aircraft systems pertinent to the Servo Drive and the control cables connected to them had been carried out, it was concluded that, until the moment of the occurrence, the planned maintenance as executed could not reduce the possibility of an event of that nature occurring
Thus, since the mechanism that led to the failure of the PP-PTQ aircraft's control cable was only identified through examinations with optical and electronic equipment (Stereoscope and SEM), it is possible that the inspections programmed by the manufacturer were not the most appropriate method for determining whether these components remain in service or not.
