A Fleet That Stopped Flying

Between 1996 and 2007, Colombia bought 25 Mi-17 helicopters from Russia for its Army. For two decades they were a central piece of troop and cargo transport in mountain and jungle areas, where their lift capacity and ruggedness made them hard to replace. In September 2026, the Army itself described the state of the fleet it still holds: twenty aircraft in three versions, of which eight are in operation and maintenance, nine remain in a preservation program awaiting funds for overhaul, two await recovery after accidents, and one is being decommissioned. Fleet flight hours fell 46.4% in three years.

The root of the problem is not technical. The Mi-17 remains a capable aircraft. What broke was the support chain: since the start of the war in Ukraine, U.S. and European sanctions on Russian industry have complicated payments, transfers, cargo insurance and the contracting of technical services linked to the manufacturers. A helicopter that cannot receive spare parts or overhaul through normal channels is, in practice, an orphan fleet.

A Regional Problem

Colombia is not alone. In November 2023, the Peruvian Army signed a contract worth nearly USD 23 million with a Panama-registered company representing a Russian firm for the overhaul of three Russian-origin helicopters. Air cargo limitations, longer routes and transport risks delayed execution; the contract was terminated, the case went to arbitration, and the work was not completed. In Ecuador, according to information published in February 2026, a Mexico-based intermediary offered the Army the overhaul of three Mi-171 helicopters for USD 24.2 million, presenting itself as the representative of a Russian firm and with no facilities of its own.

The pattern repeats: manufacturers that can no longer provide direct support, regional intermediaries without infrastructure, and contracts that accumulate risks the buyer can hardly control.

The Real Options

An operator with an orphan fleet has, in essence, three paths, and none is free.

The first is to keep the fleet flying through alternative channels. It has the lowest immediate cost, but it concentrates risk: sanctions compliance, parts traceability, warranties that are hard to enforce, and dependence on suppliers with unproven capability. Colombia illustrates the complexity. In September 2026 it became known that the United States had ruled out taking on maintenance and spare-parts supply for these helicopters, a route that had been explored in 2024 through Foreign Military Sales. The Army then opened a new process, worth more than COP 400 billion and running through 2034, for the maintenance of 16 aircraft, open to companies certified by the Russian government. An earlier contract, awarded in 2024 to recover six helicopters, was not fulfilled.

The second path is replacement with Western platforms. It solves the underlying dependency, but it requires capital, takes years, and means rebuilding the support chain: pilot and technician training, tooling, spare parts and, for U.S. platforms, export control compliance. The modernization plan presented by the Colombian government in July 2026 included 46 helicopters to replace part of the aging fleet, although its execution was left to the incoming administration.

The third is a phased transition: keep in service the units with the lowest overhaul needs, retire those that do not justify the investment, and bridge the capability gap with other platforms until replacements arrive. It is the most realistic path for most operators, and also the one that demands the most planning.

What It Means for Industry

For Western manufacturers and suppliers, the region's orphan fleets represent replacement demand that will materialize over the coming years, though at the pace of budgets rather than operational urgency. For regional industry, the opportunity lies in the transition, which is where the longest-running work is concentrated: crew and technician training and conversion, logistics support, maintenance of incoming platforms, and engineering services to manage two fleets coexisting for several years.

The access condition is the same as across the sector: AS9110 or AS9100 certification, documented traceability and, if the replacement platform is American, the ability to operate under ITAR. Organizations that prepare now will be in a position to participate when replacements are contracted. Orphan fleets are not just a problem for defense ministries; they are the signal of an industrial cycle that has already begun.
