The maiden flight of the first production EC120 helicopter was successfully completed in 1997. The launch customer was Nozaki Sangyo in Osaka, Japan. The 500 EC120 helicopter was delivered to the German Ministry of the Interior in June 2007.

The EC120 has been ordered by more than 100 customers in over 30 countries. The helicopter is in full-scale production with about two a week being completed and delivered. 73 EC120 aircraft were ordered in 2007.

In October 2004, the US Department of Homeland Security placed an order for 55 EC120 aircraft to be used for border patrol.

The helicopters form part of the Light Sign Cutter fleet of law enforcement equipped single-engine light observation helicopters. The helicopter EC120 has two variants namely EC120B and HC120. The helicopter EC120 has two variants namely EC120B and HC120. The HC120 is a Chinese-built variant.

In November 2005, the EC120B was selected as the training helicopter platform for the Rotary Wing course (RWC) program in Singapore. Up to ten helicopters were required. The first order for six helicopters was placed in August 2006. Five helicopters have been delivered to Singapore Technologies Aerospace Ltd (STAero) for flight training of Republic of Singapore Air Force (RSAF) pilots and they entered service in January 2007.

In January 2008, 36 EC120 helicopters were ordered for the French EAALAT army aviation school, based in Dax, France. The French EAALAT received three EC120 as a part of first delivery in October 2009. The helicopters are for the initial training of pilots in the army, navy, air force and police.

The joint EC120 design team is based in the Eurocopter development and manufacturing center at Marignane in France. Eurocopter carries out the final assembly, testing and certification and is also responsible for the manufacture of the seats, rotor systems and the motor transmission.

Singapore Technologies manufactures the cockpit instrument panel, the tailboom, fins and the cabin doors The Harbin Aircraft Manufacturing Corporation of CATIC supplies the cabin, landing gear and the fuel system. An agreement for local assembly of the EC120 (designated HC120 for the Chinese market) was signed by the partnership companies in November 2003. The Chinese Army was the launch customer, with an order for eight HC120 plus 50 options. The helicopter entered service with the army in 2005.

It appears frequently during the day, and perches on the low branches of the trees or on the stone walls of all our fields. Identification : Gray plumage barred and mottled with white; rounded wings, short tail and wavy flight; the same sex.

The helicopter is very quiet with an external noise level of almost 7dB under the specified limit in current ICAO legislation. The cabin can be configured for the pilot and up to four passengers and can be used for corporate or VIP transport, medical evacuation, training, as a utility helicopter, or for a range of police or federal operations.

The helicopter's 10m-diameter, three-bladed Spheriflex main rotor rotates clockwise. The main rotor blades are of impact and corrosion resistant composite construction. The 0.75m-diameter fenestron tail rotor has eight asymmetric composite blades.

"The helicopter is very quiet with an external noise level at almost 7dB under the specified limit."

The cockpit is configured for single pilot operation under visual flight rules (VFR). Dual controls and dual VFR instrumentation are optionally equipped and the helicopter can be fully configured for training. The training helicopter is operational and 15 EC120 are in service with the Spanish Air Force.

The helicopter is equipped with a fully duplex vehicle and multifunction display engine (VEMD). The modular construction of the VEMD allows the system to be easily maintained. The liquid crystal display functions in three modes - configuration mode, maintenance mode and operational mode. The configuration mode allows the integration of optional equipment in the VEMD display. The ground crew can use the maintenance mode to display flight reports, an overlift summary report and avionics system failure report page.

The pilot uses the operational mode during flight to view the engine power and weight performance and also (T4), gas generator rpm (NG), torque, oil pressure, outside air temperature (OAT) and the generator and battery voltage and current.

The 0.8m³ luggage compartment, installed beneath the engine and at the same level as the cabin floor, is able to contain up to five large suitcases and can be accessed through the passenger cabin or by the rear doors or side door. The cabin area and luggage compartment can be combined to provide 3m³ of available cargo space allowing transportation of bulky loads.

The helicopter is powered by the Turbomeca TM 319 Arrius 2F two-module engine, rated at 335kW continuous power and fitted with FADEC (full authority digital electronic control). The two crashworthy tanks have a fuel capacity of 416l which gives a range of 731km and flight endurance of four hours and ten minutes.
