McDonnell Douglas MD-90 Accessory Maintenance Services
Introduced in 1995, the McDonnell Douglas MD-90 refined the MD-80 design with modern IAE V2500 turbofan engines, digital glass cockpit, and improved systems. The MD-90's quieter operation and better fuel efficiency provided airlines with DC-9 family reliability in a more modern package. Production ended following Boeing's McDonnell Douglas acquisition, with limited numbers built compared to the MD-80, though aircraft continue serving operators primarily in Asia and the Middle East.
