Narrative:
The Cessna 750 Citation X, N156VP, suffered a runway excursion after landing on runway 01 at Rionegro/Medellín-José María Córdova Airport (MDE) Colombia. No injuries reported.

The investigation determined that the accident occurred due to the following probable cause:

- Runway excursion, as a consequence of the disconnection of the right directional control cable system, due to asymmetry of tensions in the left directional control cable, which caused the nose landing gear to turn to the left and the aircraft to veer off the runway into the safety zone.

The following contributing factors were found:

- Unstable approach, due to high approach and landing speed, which contributed to the magnitude of the runway excursion.
- Absence of inspection procedures for the directional control system, established in the maintenance manual, in the maintenance organization contracted by the Operator, which resulted in:
- Lack of a standardized maintenance inspection procedure for the directional control system, which would allow for the identification of incorrect conditions.
- Absence of the lock nut at the adjustment point of the "push rod" directional control cable, which would have prevented the cable from turning during its vibration in the operation of the aircraft.
- Aging of the directional control cable, due to the absence of a life control procedure by the operator or the manufacturer.
