MD Helicopters MD 902 Explorer
McDonnell Douglas Helicopters MD 900 first flight: December 18, 1992
FAA certification: December 2, 1994
The MD Helicopters MD902 represents the most recent model of the MD Explorer series of helicopters. Development started in 1989 when McDonnell Douglas launched the Explorer program, the MDX. This design was the first helicopter to utilize the ubiquitous no tail rotor design (NOTAR) from the beginning. In addition, the MD Explorer became the launch platform for the Pratt and Whitney PW200 turboshaft engine. The first flight took place in 1992 and certification was completed towards the end of 1994. Issues arose during IFR certification and that was not completed until 1997.
Also, in 1997 a range of improvements were incorporated into the Explorer. These included the improved PW206E engine, revised engine inlets, improved NOTAR design, and a more powerful control system. These improvements had a positive impact on both range and endurance as well as increased gross weight. The enhanced aircraft was designated the MD902.
Further improvements have included single-pilot IFR operations, improved PW207E engine with better high and hot performance. In the 2010s, a significant effort was undertaken to update the avionics and remove the legacy CRT displays to improve reliability and reduce weight. Operationally, the MD902 has seen success in the EMS and law enforcement arenas with over half of the MD902 produced being employed in these areas.
