Which of the following documents is specifically focused on maintenance procedures for the H60 aircraft?

The document A1-H60CA-MRC-390 is specifically tailored to outline maintenance procedures for the H60 aircraft, which includes both the maintenance management and scheduling aspects essential for the aircraft’s proper upkeep and operational readiness. This guide is critical for plane captains and maintenance personnel, as it details the required inspections, servicing procedures, and other maintenance actions that ensure the aircraft remains in an airworthy state.

The other options, while relevant to aviation and military operations, pertain to different documents with broader scopes or for other aircraft.
