Satena

Most airlines fly where money can be made. Satena flies where nobody else goes. Since 1962, Colombia’s state-owned regional airline has connected villages in the Amazon region, ports on the Pacific coast and settlements in the vast eastern plains with the rest of the country. For spotters, Satena is therefore a small treasure chest: turboprops instead of jets, unusual runways and, since 2026, a very special aircraft in the fleet. Here you learn how the airline works, what it flies and how to recognize it.

Satena at a glance

Satena is Colombia’s state-owned regional airline. The name is an abbreviation: Servicio Aéreo a Territorios Nacionales, loosely translated “Air Service to the National Territories.” The airline was founded on April 12, 1962, by decree of the then president Alberto Lleras Camargo. The mission was clear from the start: make regions accessible that were little developed and had few or no road connections.

To this day that is the core of the airline. Satena describes itself as a link to the “Colombia profunda,” that is, deep, remote Colombia, and advertises with the slogan “La Aerolínea de los Colombianos.” By its own account it serves over 60 destinations on more than 150 routes. The company is headquartered in Bogotá in the Fontibón district, not far from El Dorado Airport.

Satena is not a network carrier like Avianca or a low-cost brand like Wingo. Many routes are barely profitable – they exist because the state wants to secure the connection of its regions. That is exactly what makes Satena so interesting for spotters: it serves destinations that appear on no other schedule.

Codes and callsign

• IATA code 9R: appears in the flight number, on departure boards and tickets.
• ICAO code NSE: appears in the air traffic control flight plan and on many flight trackers.
• Callsign SATENA: this is how the crew identifies itself on the radio – here the brand name is also the callsign.

At first glance the ICAO code NSE has little to do with the name. That is normal: ICAO codes are assigned when they are free and don’t have to match the brand name. How to match flights using ADS-B data is explained in the guide to flight tracking for spotters.

The connection to the military

Satena is a civilian airline where you buy a ticket as usual. Organizationally, though, it is closely tied to the Colombian military – which sets it apart from almost all other airlines you know.

• Since 1962 Satena has been under the control of the Colombian Air Force. Since a constitutional amendment in November 2024, the air force has been called the Fuerza Aeroespacial Colombiana.
• Since 1968 Satena has been, by law, a public entity assigned to the Ministry of Defense.
• At the top is traditionally a senior Air Force officer.

The idea behind it grew historically. In the 1960s the Air Force had the aircraft, the pilots and the experience with difficult airfields in the interior. Instead of building a completely new organization, the state used these structures for civilian scheduled service to the remote regions.

It didn’t all go smoothly. Around 2010 Satena ran into a financial crisis. The government proposed a capital injection at the time, linked to selling 49 percent of the shares. According to available information the partial sale was never carried out – Satena remained fully state-owned.

Other countries in the region took a similar path: in Ecuador, TAME, a state airline that grew out of the air force, flew for decades until it was dissolved in 2020. Boliviana de Aviación is also a state carrier, though with jets and a completely different network.

History in stages

The list of former types reads like a tour through regional aviation: besides the aircraft mentioned, Satena also operated Boeing 727s, Embraer EMB 120 Brasilias at times and, from 2020 to 2022, Embraer E170s. If you are interested in the classics, Planetrack has type pages on the Douglas DC-3 / C-47, the HS 748, the Fokker F28 and the DHC-2 Beaver.

The fleet: turboprops for difficult runways

The exact numbers are changing noticeably right now because Satena is taking over new Twin Otters and handing back older aircraft. According to available fleet overviews, the picture in 2026 is roughly this:

Type	Number (approx., 2026)	Seats	Role	Spotter tip
ATR 42-500 / 42-600	about 9	48	Backbone for smaller regional airports	42-600 has a glass cockpit, hardly distinguishable from the -500 on the outside
ATR 72-600	about 6–7	70	Routes with higher demand	Much longer fuselage than the ATR 42
DHC-6 Twin Otter	about 5–6, more on order	19	Short, simple runways in remote regions	High-wing with fixed landing gear, including the 1,000th Twin Otter built
Embraer ERJ-145	2	50	Only jets in the fleet	Phase-out model, retirement announced

The backbone is the turboprops from ATR. The ATR 42-600 and the older ATR 42-500 suit short runways and smaller markets, the ATR 72-600 routes with more demand. On short distances turboprops burn less fuel than jets and cope with simpler airfields – ideal for Satena’s network.

The DHC-6 Twin Otter is the tool for the really difficult destinations. This twin-engine short-takeoff aircraft from De Havilland Canada lands on very short and unpaved runways. In March 2026 the manufacturer delivered the one-thousandth Twin Otter ever built to Satena – a real collector’s item, because the type has been produced on and off since the 1960s.

The Embraer ERJ-145 is the last jet in the fleet. Satena has announced it will retire the aircraft. If you still want them in your logbook, better not wait too long.

ATR 42 or ATR 72? How to tell them apart

At Satena both ATR sizes often stand side by side. From the front they look almost the same; from the side the fuselage reveals the version.

Telling the ATR 42-500 and 42-600 apart is harder: from the outside the differences are minimal, and the deciding factor is the glass cockpit inside. Here, matching the registration against a fleet list or the tracker helps. You will find more tips on high-wing propeller aircraft in the guide Telling ATR and Dash 8 apart.

How to recognize Satena

The surest clue is the “SATENA” title on the fuselage. Then there is the type mix: an ATR turboprop or a Twin Otter with this name at a Colombian airport is practically unambiguous. Colombian civil aircraft carry registrations with the prefix HK-. How registrations are built is explained in the article Understanding aircraft registrations.

There is a risk of confusion above all with Clic, the former EasyFly, which also uses ATR turboprops in Colombian domestic service. So always look at the titles and the registration, not just the aircraft type.

Spotting Satena: where and how

You won’t see Satena in Germany or anywhere in Europe. The network lies almost entirely in Colombia; on its website the airline also offers a connection between Montería and Panama. If you want Satena in your logbook, you have to go to South America.

At large airports like Bogotá, Satena shares the sky with Avianca, LATAM Airlines Colombia and Wingo. Among Airbus and Boeing jets the turboprops stand out immediately – and because they approach more slowly, you have more time for the photo. For sharp pictures with visibly spinning propellers, the guide to propellers and shutter speed helps.

The small destinations are more exciting than the capital. At airfields in the Amazon or on the Pacific coast, a Satena flight is often the event of the day. Many of these airports have no designated spotting places. The rule here: only take photos from publicly accessible areas, respect barriers and ask if in doubt. In Colombia airports are partly used by the military too, which can make the rules stricter.

Accidents and safety

Like many airlines that have flown in difficult terrain for decades, Satena has experienced serious accidents. Especially in the 1960s to 1980s several aircraft crashed, including C-47s, HS 748s and, in 1985, a Fokker F28 near Florencia. In May 2010 an ERJ-145 skidded off the runway on landing at Mitú on a wet runway and came to rest in a field; all 41 people on board survived, but the aircraft was a total loss.

In January 2026 a Beechcraft 1900D on a Satena flight from Cúcuta crashed in mountainous terrain; all 15 people on board were killed. According to available information the aircraft was operated by a partner company. The cause is being investigated by the Colombian authorities.

Common mix-ups

• Thinking Satena is a military airline – Satena is civilian, only organizationally closely tied to the air force.
• Assuming every Colombian ATR is Satena – Clic also flies ATRs domestically. Titles and registration decide.
• Mixing up the ATR 42 and ATR 72 – fuselage length is the easiest feature.
• Equating flight number with operator – on some routes partners fly under Satena flight numbers.
• Using old fleet lists – Dornier 328, E170 and Y-12 are retired, the Twin Otter fleet is growing.

Conclusion

Satena is an airline with a mission: since 1962 it has brought aircraft to places where roads are missing and other airlines don’t want to go. The close tie to the air force, the turboprop fleet of ATRs and Twin Otters and destinations deep in the rainforest make it one of South America’s most unusual airlines. How rare such a sighting is for European spotters can be judged with the guide Judging the rarity of a sighting.
