Our Maintenance Step Kit provides a secure work platform that is ideally located on the left and/or right side of the aircraft roof so that it can be used by the pilot and maintenance personnel to perform inspections on the main rotor and transmission. The fixed provisions install easily with bolts into existing plug locations (for blade fold and mooring provisions) at STA 5795.0 and 5128.3 and the quick release step secures to fixed provisions in seconds locking in place with 2 push pins. Step can then be removed without tools for improved aesthetic and weight savings. Fabricated from sturdy CNC machined components, the Maintenance Steps feature a non-slip embossed relief pattern for added personnel safety and a machined design for additional durability. *Provisions install at existing plug locations at STA 5795.0 and 5128.3 on the LH roof. Not compatible with MR Blade Fold & Helicopter Mooring Provisions kit. Cannot be used for mooring/securing the helicopter. 1 kit completes the RH side of the aircraft.
