Description
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 kit installs easily with bolts into existing plug locations (for blade fold and mooring provisions) at STA 5795.0 and 5128.3. 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.
