Two T-37Cs and two A-37Bs were sent to patrol the maritime regions of Serranilla, Roncador and Quitasueños, after the Nicaraguan government challenged Colombian sovereignty in the area. San Andrés remains an outpost for the FAC: as of mid-March, last year, six Kfir C10s and the sole Boeing 767-200MMTT could be found there. In the early 1990s another 12 surplus USAF T-37Bs supplemented the C-models. Above: A Tweet resplendent in the late afternoon sun.

Change of course On July 20, 2006, T-37C FAC 2104 crashed on its return to base after a military parade, killing two pilots, instructor Lt Herman Ramirez and Lt Herrera Cortes. Post-accident studies revealed severe structural issues in the Tweet and the FAC’s investigative team concluded these problems caused one of the wings to become detached. The FAC General Command was forced to ground its entire fleet of T-37C and T-37B aircraft. However, the need to continue transitioning fighter pilots led the FAC to return four T-37Bs (FAC 2116 to FAC 2120) to service and it was later decided to purchase another 16 surplus trainers from USAF stocks. These jets arrived in Colombia in four separate batches between 2008 and 2010.

Kfir C10/C12 and TC12, the AC-47T, Cessna will reach the end of its service life within ten years and the current operational status greatly depends on the availability of spare parts, together with structural fatigue. Before long, however, the FAC will have to search the market for a suitable replacement. The leading manufacturers of jet trainers have already begun to offer their products, and some have had talks with the FAC. Offers could include the Aero Vodochody L-39NG, BAE Systems Hawk Mk128, Leonardo M-345 and M-346 and the Textron AirLand Scorpion. A new jet trainer is likely to be required to replace both the T-37 and the A-37 of Escuadrón de Combate 311, providing dual-use training and attack capabilities. Colombia’s peace deal with the FARC, and the push for a similar treaty with the Ejército de Liberación Nacional (ELN, National Liberation Army) guerrilla group might lead to a reduction in the defence budget, which would make any future military procurements uncertain.
