Some sources refer to the AK1-3 as the Sanka or San'ka while others do not. [1] [2]

Design and development

The AK1-3 was designed to comply with the Ukrainian AP-27 rules, which are similar to the European Aviation Safety Agency CS-27 standard. The aircraft features a single main rotor with a tail rotor, a two-seats-in side-by-side configuration enclosed cockpit, skid-type landing gear and a four-cylinder, air-cooled, four-stroke, 156 hp (116 kW) Subaru EJ25 automotive engine. [1]

The aircraft's 6.84 m (22.4 ft) diameter three-bladed Starflex rotor has a chord of 15 cm (5.9 in) and employs a unique torsion bar blade mounting that allows blade movement to produce pitch angle changes, flapping, as well as lead and lag. The main transmission consists of belt drives, with the tail rotor driven by a solid shaft. The aircraft has an empty weight of 380 kg (838 lb) and a gross weight of 650 kg (1,433 lb), giving a useful load of 270 kg (595 lb). With full fuel of 75 litres (16 imp gal; 20 US gal) the payload is 216 kg (476 lb). [1]

The design received a Ukrainian type certificate in 2006. [3]

In 2009 Aerokopter (DB Aercopters) was acquired by the Perla Group of companies Perla Aviation division, with the stated intention of moving the assembly line of the AK1-3 to the United Arab Emirates (UAE). [4]

By December 2020 the company reported 102 helicopters had been delivered. [3]

Operational history

By December 2020 one 2008 model AK1-3, serial number 1001, had been registered in the United States with the Federal Aviation Administration in the Special Certificate of Airworthiness Experimental-Exhibition category. It was registered in January 2018. [5] The same aircraft, serial number 1001, had been previously registered with Transport Canada in the Special Certificate of Airworthiness - Limited Category from 2009 to 2015, prior to being exported to the US in 2015.
