In November 1997 Pilatus flew a modified PC-7 Mk.II in order to test improvements for a next generation turboprop trainer. As a result of these tests, Pilatus funded the development of a new training system in November 1998. Development of the PC-21 started in January 1999. Roll-out of the PC-21 prototype was on 30 April 2002 at Pilatus' factory in Stans, Switzerland, with the first flight taking place on 1 July of the same year. The second PC-21 prototype flew on 7 June 2004. One of the prototypes, HB-HZB, crashed on 13 January 2005, in Buochs, Switzerland on an aerobatic training flight, killing the pilot and injuring another person on the ground. The other prototypes: HB-HZA, HB-HZC and HB-HZD, are still flying.
The PC-21 is a completely new aircraft design. The aircraft features a tandem-seating arrangement (student in-front/instructor behind) in a bird strike resistant glass canopy with all round vision, glass cockpit with three large colour liquid crystal displays (LCD), head-up displays (HUD), Hands on Throttle and Stick (HOTAS) controls and Zero-zero ejection seats for student and instructor.
On 21 January 2008, the first PC-21 for the Republic of Singapore Air Force completed its flight test prior to being accepted into service. On 13 July 2008, the type began to provide the RSAF with basic flying training. A further six aircraft have now been delivered with the remaining seven expected to be delivered in August 2008.
During the 2009 Dubai Airshow, UAE announced an order of 25 PC-21 for the United Arab Emirates Air Force to replace their aging fleet of Pilatus PC-7s. UAEAF's first PC-21 made its maiden on 22 November 2010, deliveries expected to commence from first quarter of 2011.
The PC-21 was offered to the Royal Australian Air Force as part of project AIR 5428 to replace its Pilatus PC-9s; the consortium comprising Lockheed Martin, Pilatus and Hawker Pacific ("Team 21") are reported to have won the bid. Moreover, the PC-21 has been evaluated by the Spanish Air Force, along the T-6 Texan II and the PZL-130 Orlik III, as a possible substitute for its ENAER T-35 Pillan and CASA C-101 Aviojet trainer aircraft.
