On October 26, 2023, a Cessna 208B Grand Caravan, HK-3804, crashed in a rural area near San Antonio de Prado, Colombia, resulting in the fatalities of the copilot, two passengers, and a newborn baby. The aircraft departed Medell¡n-Enrique Olaya Herrera Airport at 11:58 hours on a domestic charter flight to Jurad¢, and was cleared to fly on a runway course to Cerro El Volador and then make a turn to the right, in a visual climb until crossing the town of San Antonio de Prado. ATC reported the aircraft was estimated to cross the position of San Antonio de Prado at 12:00, but no notification was received. At 13:00, the aircraft was found crashed. The investigation by Aerocivil revealed that the crew used an empty basic weight of 5254 lbs (2383 kg), significantly below the aircraft’s actual weight of 5411 lbs (2454 kg). Furthermore, the crew did not account for the 650 kg of cargo onboard, which significantly reduced the aircraft’s takeoff weight. The crew’s calculations resulted in a takeoff weight of 8719 lbs (3955 kg), which was below the maximum takeoff weight of 8750 lbs (3970 kg). The actual takeoff weight was 10320 lbs (4681 kg). The incident was likely caused by a take-off with a weight approximately 17% higher than the maximum gross operating weight (MTOW) established for the C208B aircraft. Limited climb rate with signs of lift loss due to the overweight during the initial climb, and a forced landing in mountainous terrain due to loss of lift caused by the overweight during the initial climb, contributed to the incident.On October 26, 2023, a Cessna 208B Grand Caravan, HK-3804, crashed in a rural area near San Antonio de Prado, Colombia, resulting in the fatalities of the copilot, two passengers, and a newborn baby.
