The Mil Mi-38 is a transport helicopter designed by Mil Moscow Helicopter Plant. Originally intended as a replacement for the Mil Mi-8 and the Mi-17, it is being marketed in both military and civil versions.[1] It flew for the first time on 22 December 2003 and was certified on 30 December 2015.[2]
Design and development

The manufacturer plans to provide the Mi-38 with a new Tranzas "glass cockpit" avionics system and new composite main rotor blades. The helicopter is offered with a choice of either Klimov TV7-117V or Pratt & Whitney Canada PW127/TS turboshaft engines. The second prototype, powered by the PW127TS, made its first flight in December 2010.[3] In 2013, the third prototype has been assembled at the Kazan Helicopter Plant.[4]
The Mil Mi-38 prototypes have already set five records in the E1h class. The second prototype aircraft set an altitude record by reaching 8,620 meters (28,280 feet) without a payload. The second and third records were for climbing speed; the Mi-38 reached a height of 3,000 meters (9,843 feet) in six minutes, then followed this to reach 6,000 meters (19,685 feet) in 10 minutes and 52 seconds. Two further records were altitude records: the first was set at 7,895 meters (25,902 feet) with a 1,000-kg (2,205-lb) payload, the second at 7,020 meters (23,031 feet) with a 2,000-kg (4,409-lb) payload.[5][6]
On 30 December 2015, Rosaviatsiya certified the Mi-38, completing the testing and certification program and allowing for the delivery of the first production model. Certification was based on the third and fourth flight-test prototypes with 2,500 shp Klimov TV7-117V engines.[2]
