The Mitsubishi Regional Jet (MRJ), now known as the SpaceJet, was developed by Mitsubishi Heavy Industries (MHI) to compete in the 70–90 seat regional jet market. MHI officially launched the program on March 28, 2008, with a foundational order from All Nippon Airways. The aircraft was intended to be Japan’s first domestically designed passenger jet since the NAMC YS-11. MHI, the manufacturer, has a long and varied history in Japan, establishing itself as the country’s largest private firm in 1934 by manufacturing ships, heavy machinery, airplanes, and railroad cars.
A range of platforms and access solutions address maintenance needs across the aircraft structure. Modular Stepover Platforms and Bridge Deck platforms facilitate access over the wing and center fuselage for work on the Wing Box, Fuel Tanks, and Emergency Exit. The Cantilever Platform offers specialized access to the Nose Section (Radome, Windshield & Cockpit) and certain areas of the Wing & Engine Pylon (Inlet/Exhaust, Undercowl). Maintenance requiring elevated access, such as the Tail Section (Vertical Stabiliser, Horizontal Stabiliser, Rudder, APU Compartments) and the AFT Fuselage, benefits from the Super Trestle Scaffold and Ultraraise systems. For wheel and braking system checks, the Landing Gear (NLG and MLG) utilizes sturdy Super Maintenance Stands. Essential equipment, including the Platform Ladder Warthog and Easyraise, supports general inspection and access to the Forward Fuselage (Cabin Access, Cargo).
