scope:

This standard practice describes the U.S. Army Rotorcraft Structural Integrity Program (RSIP), which defines the requirements necessary to substantiate and maintain structural integrity in U.S. Army rotorcraft.

Application. This standard practice applies to rotorcraft structure, as defined in section 3.31, regardless of rotorcraft type, until the rotorcraft is retired, declared excess, or demilled. For the purposes of this standard practice, the term rotorcraft includes conventional helicopters, tilt rotors, tilt wing, co-axial, and compound helicopters. Rotorcraft structure includes fuselage, tailboom or tailcone, empennage, wings, stabilizers, stabilators, sponsons, landing gear structural components, interfaces and provisions, as well as rotors and rotor components, rotating and non-rotating rotor control mechanism components, propellers, proprotors, and any transmission and drive-systems components that experience flight-maneuver loads, control-surface induced loads, or loads imparted by fuselage, tailboom or tailcone, empennage, or flight-control mounts.

Purpose. This standard practice provides direction to government personnel and contractors engaged in the development, production, modification, acquisition, or sustainment of U.S. Army rotorcraft structures.
