Colombian authorities are investigating whether mechanical failure, human error or excess weight caused the crash of a military C-130 aircraft that has now left at least 69 dead, as a political dispute intensifies over the condition of the country’s aging air fleet.

The aircraft, a Lockheed C-130 Hercules operated by the Colombian Aerospace Force (FAC), went down shortly after take-off on Monday near Puerto Leguízamo, in a remote jungle region bordering Peru and Ecuador.

The plane, identified as FAC 1016, was carrying 128 personnel when it crashed minutes after departure en route to Puerto Asís, roughly 200 kilometres away. Officials have confirmed dozens of survivors, though many remain hospitalised with injuries ranging from minor trauma to severe burns.

Emergency crews faced major challenges reaching the crash site due to the dense Amazonian terrain, while the impact and subsequent fire — compounded by detonations from ammunition on board — left many bodies severely damaged, complicating identification efforts.

Aging aircraft under scrutiny

The C-130H aircraft had been in service since 1983 and was donated to Colombia by the United States in 2020 as part of long-standing bilateral defence cooperation. It underwent a major maintenance overhaul in 2023, including structural inspections and system upgrades, before being returned to operation.

Despite its age, military officials insist the aircraft remained within operational limits. General Carlos Fernando Silva publicly contradicted President Gustavo Petro’s description of the aircraft as “scrap”, presenting detailed figures on its operational life during a televised cabinet meeting alongside Defence Minister Pedro Sánchez and senior military officials.

General Silva said the aircraft had flown 345 hours between 2021 and 2024, and 537 hours in 2025, broadly in line with standard annual usage of around 500 hours. Based on remaining flight capacity — estimated at up to 20,000 hours — he said the aircraft could theoretically continue operating for decades if strict maintenance protocols were followed.

Concerns have emerged from U.S. defence officials regarding maintenance standards and the availability of spare parts for aircraft supplied to Colombia, according to reports by El Tiempo. Sources cited by the newspaper said such aircraft can operate safely for around 10,000 hours, provided rigorous inspection and servicing regimes are maintained.

United States Southern Command has offered to support Colombia’s investigation with a technical team, underscoring the importance of determining whether maintenance, logistics or operational factors contributed to the crash.

Authorities reiterated there is no indication the crash was caused by hostile action, despite the aircraft going down in a region where dissident factions of the former FARC operate and where coca cultivation is widespread.

Investigators are focusing on three main hypotheses: mechanical failure, pilot error, or overloading at take-off. Officials said flight data, maintenance records and communications with air traffic control will be central to establishing the sequence of events.

The disaster has triggered a heated political exchange between President Gustavo Petro and his predecessor Iván Duque, exposing sharp divisions over defence policy and military procurement.

Petro described the aircraft as “scrap”, criticizing past administrations for accepting donated military equipment and arguing that such decisions have weakened Colombia’s operational capacity. “A country cannot defend itself with obsolete machines,” he said, pledging that his government would prioritize acquiring new equipment and strengthening domestic defence production.

He also questioned the long-term cost of maintaining aging platforms, suggesting that donated equipment can ultimately impose higher financial and operational burdens.

Duque strongly rejected the accusation, defending his administration’s handling of the armed forces and pointing to maintenance protocols carried out before the aircraft was delivered. He noted that C-130 aircraft continue to operate in dozens of countries worldwide and urged a technical investigation into factors such as aircraft weight, runway conditions and operational procedures.

Duque also accused Petro of callous social media statements in the hours after the tragedy, calling for restraint while investigations remain ongoing.

The crash adds to six previous military aviation accidents since 2022 and raises deep concerns about the readiness and sustainability of Colombia’s air fleet, much of which relies on aging platforms acquired through international cooperation.

Analysts say the incident could intensify scrutiny over budget-cuts in defence spending, maintenance capacity and the balance between acquiring new equipment and extending the life of existing assets.

As recovery operations continue in Putumayo’s dense jungle, authorities face the dual challenge of identifying victims and providing answers to families, while determining whether the disaster reflects isolated failure or deeper systemic issues within Colombia’s military aviation infrastructure.

At least 66 people were killed after a Colombian military transport aircraft crashed shortly after take-off in the country’s southwest on Monday, authorities said, in one of the deadliest air disasters involving the armed forces in recent years.

The aircraft, a C-130 Hercules, went down at around 9:50 a.m. local time near the municipality of Puerto Leguízamo, in a remote jungle region close to the borders with Peru and Ecuador.

According to Colombia’s Defence Ministry, 128 people were on board the aircraft, including 11 crew members from the Colombian Aerospace Force, 115 members of the army and two police officers.

By late Monday, officials confirmed 66 fatalities: six from the air force, 58 from the army and two from the police. Rescue teams managed to evacuate 57 survivors, many of whom sustained injuries. Eight were transferred to hospitals in Florencia, while 49 were flown to Bogotá, where 19 are being treated at the Military Hospital and others for less serious injuries at a military medical facility.

Authorities said one soldier survived unharmed, while four others remained missing as search operations continued in dense jungle terrain.

The aircraft, identified as FAC 1016, had taken off from Puerto Leguízamo en route to Puerto Asís, roughly 200 kilometres away, when it lost altitude and crashed within minutes of departure.

Military officials said the plane went down about two kilometres from the airport in a rural area. Witnesses reported a fireball upon impact, followed by secondary explosions.

Defence Minister Pedro Sánchez said the situation was worsened by the detonation of ammunition being transported by troops on board.

“As a consequence of the fire, part of the ammunition carried by the personnel exploded,” Sánchez said, complicating rescue and recovery efforts.

Emergency crews faced significant challenges accessing the crash site due to the remote Amazonian terrain, while the condition of many bodies has made identification difficult.

No signs of attack

Military authorities said there is no evidence so far that the crash was caused by an attack.

“At this time, there is no information or indication that this was the result of an attack by any illegal armed group,” said General Hugo López, who added that a full investigation is underway.

The region where the aircraft crashed is known for the presence of dissident factions of the former FARC guerrilla group, which operate in areas with extensive coca cultivation used for cocaine production. However, officials stressed that current evidence points away from sabotage.

Questions over aircraft condition

The crash has triggered a political debate over the condition of Colombia’s military fleet, just weeks ahead of the country’s presidential elections.

The aircraft involved was a C-130H Hercules, an older variant of the widely used military transport plane originally introduced in the 1960s by Lockheed Martin.

According to available data, the aircraft had been in service since the early 1980s and was transferred to Colombia by the United States in 2020.

President Gustavo Petro suggested the plane represented outdated equipment acquired by a previous administration.

“In 2020, scrap was purchased,” Petro said on social media, referring to the government of former president Iván Duque. He added that his administration had sought to modernize military equipment but faced bureaucratic obstacles.

Opposition figures, however, argued that budget cuts under Petro’s government have affected maintenance and operational readiness within the armed forces.

In a message posted online, Petro expressed condolences to the families of the victims and praised residents of Putumayo who rushed to assist survivors.

“This is how a nation is built,” he wrote, thanking locals who reached the crash site on foot and by motorcycle to provide water and aid.

Authorities said the investigation will examine technical, mechanical and operational factors, including maintenance records and flight data, as Colombia seeks answers to a tragedy that has shaken the country’s military and reignited debate over defence policy.

Colombian authorities said on Thursday they have found no evidence so far of “external factors” contributing to the crash on Wednesday of a SATENA Beechcraft 1900 aircraft on the Cúcuta–Ocaña route , which killed all 15 people on board.

The conclusions were presented during a press conference held at Ocaña airport in the northeastern department of Norte de Santander. The briefing was led by Major General Óscar Zuluaga Castaño, president of Colombia’s state-owned airline SATENA, and Jorge Campillo, president of aviation company SEARCA, which operated the aircraft under a charter arrangement. Local officials, including Ocaña’s acting mayor and government secretary Hugo Guerrero, also attended.

The aircraft crashed on Jan. 28 while operating Flight NSE 8849, which departed from Camilo Daza Airport in Cúcuta at 11:42 a.m. local time and was scheduled to land in Ocaña at around 12:05 p.m. Contact with air traffic control was lost at 11:54 a.m. while the plane was flying over the Catatumbo region, a mountainous area long affected by armed conflict and the presence of illegal armed groups.

Authorities confirmed that all 13 passengers and two crew members died in the crash. Among those on board were Congressman Diógenes Quintero and Carlos Salcedo, a candidate for Colombia’s House of Representatives.

Officials said that, at this stage of the investigation, there is no indication that the aircraft was affected by “external factors”. The term refers to events such as the aircraft being struck by a drone or the involvement of a terrorist-related incident, including a bombing.

According to flight-tracking data from FlightRadar24, the Beechcraft 1900 had reached a cruising altitude of approximately 12,000 meters before beginning its approach to Ocaña near the town of Ábrego. The aircraft then descended to about 7,900 meters moments before disappearing from radar. The plane has only been in the air 12 minutes for a 20-minute flight. Authorities said there is still no information regarding the recovery of the aircraft’s flight data recorder or cockpit voice recorder.

SATENA and SEARCA said the aircraft, registration HK-4709, met all airworthiness and maintenance requirements and was operating under approved technical and regulatory standards at the time of the accident. Weather conditions along the route and at the destination airport were described as favorable for flight operations. According to the air traffic controlers at Ocaña, the final words from the cockpit were: “We are ready to descend”.

The pilot in command, Manuel Vanegas, had accumulated more than 10,000 flight hours, while the co-pilot, José Joaquín de la Vega, had logged over 7,000 hours, officials said. Both crew members were operating within the duty-time limits established by Colombia’s aviation regulations, with no indications of fatigue or excessive workload.

The Cúcuta–Ocaña–Medellín route began operations in March 2025 under which SEARCA is responsible for the aircraft, maintenance, crews and insurance. SATENA said SEARCA has provided services to the airline for more than 25 years, with a track record supported by compliance with technical, operational and regulatory standards.

Over the past seven years, SEARCA has transported more than 269,000 passengers across nearly 17,800 flights, accounting for more than 12,400 flight hours, according to SATENA. During 2025 alone, SEARCA conducted more than 7,000 flights on 25 routes, representing 16.5% of SATENA’s total operations.

Officials said all aircraft operated by SATENA and SEARCA are equipped with mandatory terrain awareness and warning systems, as well as additional technology designed to allow safe operations in areas with complex topography, such as the Catatumbo mountain range.

The region where the aircraft went down has seen repeated clashes between the ELN guerrilla and dissident factions of FARC, as well as violence linked to drug trafficking routes and other illicit economies. Authorities said the rugged terrain complicated access for emergency and recovery teams during the initial search and rescue operation.

SATENA said the determination of the cause of the crash will rest exclusively with Colombia’s aviation accident investigation authorities, working alongside the Colombian Aerospace Force and judicial entities. SEARCA said it is fully cooperating with the investigation and will provide all documentation and information requested.

Despite the accident, SATENA confirmed it will not suspend operations on the route, citing its mandate to maintain connectivity to remote regions of the country. The airline said it will continue operating with heightened oversight and coordination with aviation authorities.

SATENA and SEARCA reiterated their condolences to the families of the victims and said providing institutional support and accompaniment to relatives remains a priority as the investigation continues.
