Eurocopter EC-135

The Eurocopter EC135 (now Airbus Helicopters H135) is a twin-engine civil light utility helicopter produced by Airbus Helicopters (formerly known as Eurocopter). It is capable of flight under instrument flight rules (IFR) and is outfitted with a digital automatic flight control system (AFCS). First flying on 15 February 1994, it entered service in 1996 and 1,400 have been delivered up to September 2020 to 300 operators in 60 countries, accumulating over 5 million flight hours. It is mainly used for helicopter emergency medical services, corporate transport, law enforcement, offshore wind support, and military flight training. Half of them are in Europe and a quarter in North America.

In 2011, Eurocopter announced that the 1,000th EC135 to be produced had been delivered to German operator ADAC, roughly 15 years following the start of production.[29] In 2012, Flying Magazine recognised the EC135 as being "the industry's best selling twin-engine helicopter".

In 2013, it was reported that the EC135 was currently providing roughly 25% of the world's total emergency medic services flights, and that over 500 EC135s have been delivered to in an aeromedical configuration.[36] By late 2013, during which a brief grounding of the type was instigated due to safety concerns of fuel gauges, it was noted that the EC135 made up half of the UK's operational air ambulance fleet.[37] In October 2014, the first EC135 air ambulance to be delivered in the Chinese market took place.[38]

The German Army operates a total of 19 H135s as basic trainers at the School of Army Aviation in Bückeburg, these have had an average operational availability in excess of 95 per cent;
