Runway Excursion of Cessna 402B (HK-4353) at Pizarro Aerodrome (HK4353)

Incident Overview and Flight Details On July 13, 2013, a Cessna 402B with registration HK-4353, operated by Aeroexpreso del Pacifico S.A. (AEXPA S.A.), departed from Gerardo Tovar Lopez Airport (SKBU) in Buenaventura at 17:20 local time. The aircraft was en route to Pizarro Aerodrome in the Bajo Baudó municipality of the Chocó department. The flight carried two crew members, seven adult passengers, and two children, totaling 11 people on board. The aircraft was fueled with 60 gallons of fuel, and the weight and balance manifest was completed according to dispatch documents. The flight proceeded without incident until the final approach to runway 33 at Pizarro Aerodrome. The crew reported that the aircraft was properly configured for landing, with visibility greater than 10 kilometers and a cloud ceiling of 5,000 feet. However, as the aircraft approached touchdown, the pilot reported a sensation of being unable to control the aircraft's attitude. To avoid a total loss of control, the pilot applied increased power during the final part of the approach. During the landing roll and braking, the crew was unable to maintain the runway centerline, resulting in a runway excursion to the right side. The aircraft came to a stop in the safety area, approximately 50 meters from the end of the runway, at a deviation of about 60 degrees from the runway centerline. The abrupt change in direction was attributed to increased drag on the right main landing gear as it moved over grassy, muddy terrain. The pilot commanded the evacuation, and all 11 occupants exited the aircraft unharmed and by their own means. No post-incident fire occurred. The incident was officially recorded at 17:50 local time under visual meteorological conditions. The crew immediately notified the operator and the Regional Inspector of the Colombian Civil Aviation Authority in Pereira. The aircraft sustained minor damage to the lower fuselage skin and the nose gear doors. The investigation noted that the Pizarro Aerodrome lacked local meteorological information, but forecasts for the Pacific Litoral area indicated no cyclonic systems or adverse atmospheric disturbances, with prevailing winds from west to east at less than 10 knots. METAR reports from Buenaventura and Quibdó at 23:00 UTC also indicated appropriate conditions for the area.
