Design and development

After the success of the EMB-110 Bandeirante, Embraer began the development of their first transport category airliner in 1974. The so-called Family 12X comprised three models with modular concept designs: EMB-120 Araguaia, EMB-123-Tapajós and EMB-121 Xingu. EMB-121 was the sole 12X model effectively produced. Araguaia's name was changed to Brasilia in 1979 at the official launching of the project, when at a CAAA (Commuter Airline Association of America) convention at USA several suggestions from prospective operators were collected and incorporated to EMB-120 design. Thus, a completely new aircraft – no longer related to the 12X family – was launched. No common parts from EMB 121 Xingu were used, and the capacity was revised from 24 to 30 seats. Originally designed to utilise the new 1500SHP Pratt & Whitney Canada PW115 turboprop, it was later upgraded to the 1892 ESHP PW118.

Probably the closest to a modern replacement for the DC-3 with half again as much speed, the Brasilia attracted immediate interest from many regional airlines, particularly in the USA. The size, speed and ceiling allowed faster and more direct services around the US and Europe, compared to similar aircraft. The first aircraft entered service with Atlantic Southeast Airlines in October 1985. The basic EMB-120RT was upgraded to the extended range (1,575 km) EMB-120 ER, with older aircraft retrofitted via a Service Bulletin.

Operational history

Most of the EMB 120s were sold in the United States and other destinations in the Western Hemisphere. Some European airlines such as Régional in France, Atlant-Soyuz Airlines in Russia, DAT in Belgium, and DLT in Germany also purchased EMB-120s. Serial production ended in 2001. As of 2007, it is still available for one-off orders, as it shares much of the production equipment with the ERJ-145 family, which is still produced. The Angolan Air Force, for example, received a new EMB 120 in 2007.

SkyWest Airlines operates the largest fleet of EMB 120s under the United Express and Delta Connection brand. Great Lakes Airlines operates six EMB 120s in its fleet, and Ameriflight flies eight as freighters.

Accidents and incidents

• On September 19, 1986, an Atlantic Southeast Airlines EMB 120RT (N219AS) struck a mountain near Mantiqueira, Brazil while being delivered to Atlantic Southeast, killing all five on board.
• On July 8, 1988, Brazilian Air Force Embraer EMB 120RT Brasília FAB-2001 crashed during an engine-out landing at São José dos Campos. Five of the 9 occupants died.
• On April 5, 1991, Atlantic Southeast Airlines Flight 2311 crashed at Brunswick, Georgia. The crash claimed the lives of all twenty-three people on board, including former U.S. Senator John Tower of Texas and astronaut Sonny Carter. This was due to propeller control failure. The aircraft was operating for Delta Connection.
• On September 11, 1991, Continental Express Flight 2574, broke up in flight and crashed at Eagle Lake, Texas, killing all 14 passengers and crew members. The NTSB determined that missing screws on the horizontal stabilizer led to the crash.
• On August 21, 1995, Atlantic Southeast Airlines Flight 529, crashed in a field near Carrollton, Georgia. Of the twenty-nine people on board, ten were killed. This was due to failure of a propeller blade and subsequent severe engine vibration and failure.
• On January 9, 1997, Comair Flight 3272 crashed in Monroe, Michigan. All of the passengers and crew died. The probable cause was in-flight icing.
• On May 21, 1997, SkyWest Airlines Flight 724, an Embraer EMB-120 (N198SW), experienced a total loss of engine power to the right engine and associated engine fire, followed by a total loss of all airplane hydraulic systems, after takeoff from San Diego International-Lindbergh Field, San Diego, California. The airplane sustained substantial damage. The 2 pilots, 1 flight attendant, and 14 passengers were not injured. Skywest Airlines, Inc., was operating the airplane as a scheduled, domestic, passenger flight under 14 CFR Part 121. The flight was destined for Los Angeles, California. It diverted to Miramar NAS, San Diego, where it landed at 14:27 hrs. Visual meteorological conditions prevailed at the time, and an IFR flight plan was filed.
• On October 21, 1998, a Capital Táxi Aéreo EMB 120RT Brasilia registration PT-WKH crashed due to pilot error during final approach to Pinto Martins International Airport. The two-man crew and one passenger on board were killed, along with one person on the ground.
• On August 30, 2002, Rico Linhas Aéreas Flight 4823 operated by an Embraer EMB 120ER Brasília (registration PT-WRQ), en route from Cruzeiro do Sul and Tarauacá to Rio Branco crashed on approach to Rio Branco during a rainstorm, 1,5 km short of the runway. Of the 31 passengers and crew aboard, 23 died.
• On May 14, 2004, Rico Linhas Aéreas Flight 4815 operated by an Embraer EMB 120ER Brasília (registration PT-WRO), en route from São Paulo de Olivença and Tefé to Manaus crashed in the forest about 18 nmi (33 km; 21 mi) from Manaus. All 33 passengers and crew died in the worst-ever accident involving the EMB 120.
• On March 22, 2010, an Airnorth EMB 120 (VH-ANB) took off approximately 10.10am (ACST) from Darwin International Airport on a routine simulated engine-failure training exercise known as a V1 cut when it apparently banked sharply to the left and crashed into the nearby bushland at RAAF Base Darwin. The two on-board pilots were killed instantly.
• On September 14, 2011, Angolan Air Force Embraer 120ER T-500 crashed while attempting to take off from Huambo Airport, killing 17 of 23 on board.
• On October 12, 2011, a Nationale Regionale Transport EMB-120, registration ZS-PYO (MSN: 120245) performing a charter flight from Libreville to Port Gentil (Gabon), overran runway 21's end and came to a stop with the nose gear intact, both main gear struts bent backwards causing the engines to "pitch down" together with the wings. A few passengers sustained minor injuries, but the aircraft was damaged beyond repair and was written off.
• In February 2012, Everts Air Cargo Flight 1290, lost all pitch control due to poor maintenance procedures. The EMB landed safely in Illiamna, AK without further incident.
