After German certification was granted on 18 December 1981, the first Dornier 228-100 entered service in the fleet of Norving in July 1982. The first operator of the larger Dornier 228-200 entered service with Jet Charters in late 1982. Certification from both British and American aviation authorities followed on 17 April and 11 May 1984 respectively. By 1983, the production rate of the Dornier 228 had risen to three aircraft per month; at this point, Dornier had targeted that 300 Dornier 228s would be produced by the end of the 1980s. In November 1983, a major license-production and phased technology-transfer agreement was signed between Dornier and Hindustan Aeronautics Limited (HAL) was signed; a separate production line was established and produced its first aircraft in 1985. By 2014, a total of 125 Dornier 228s had been produced in India.
