Embraer EMB 120 Brasilia
 

The Embraer EMB 120 Brasilia is a twin-turboprop commuter airliner, produced by Embraer of Brazil.

Design & Development

After the success of the EMB-110 Bandeirante, Embraer began the development of their first transport category airliner in 1974. Originally called the Araguaia, the name was changed to Brasilia in 1979 at the official launching of the project. The design retained the T-tail and supercritical wing of the EMB 121 Xingu, but with the capacity for 30 seats. Originally designed to utilise the new 1500SHP Pratt & Whitney Canada PW115 Turboprop, this was later upgraded to the 1892 ESHP PW118.

Probably the closest to a modern replacement for the DC-3 (with double the 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.

In total, 352 Brasilia airplanes were delivered to 33 operators around the world.

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

Brazilian Air Force on July 8, 1988 an Embraer EMB 120RT Brasília registration FAB-2001 crashed during an engine-out landing at São José dos Campos. Five of the 9 occupants died.

Atlantic Southeast Airlines Flight 2311, crashed in Brunswick, Georgia on April 5, 1991. 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.

Continental Express Flight 2574, broke up in flight on September 11, 1991, killing all of the passengers and crew members. The NTSB determined that missing screws on the horizontal stabilizer led to the crash.

Atlantic Southeast Airlines Flight 529, crashed in a field near Carrollton, Georgia on August 21, 1995. 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.

Comair Flight 3272 crashed in Monroe, Michigan on January 9, 1997. All of the passengers and crew died. The probable cause was in-flight icing.

Rico Linhas Aéreas flight 4823 on August 30, 2002, operated by the 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, 1,5km short of the runway.

The two on-board pilots were killed instantly.

On September 14, 2011, an Angolan Air Force Embraer 120ER crashed and broke on to two pieces while attempting to take off from Albano Machado Airport killing 30 of the 36 onboard.

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.
