The components tab in The Official Helicopter Blue Book® list the intervals of major drivetrain helicopter components and Hourly Maintenance Costs (HMC).

The major (rotating) individual part or assembly which normally has a scheduled or historical removal interval. The general categories of airframe components are: Rotor blades, transmissions, flight controls, rotor heads, hydraulic systems, driveshafts, and engines with their major controls. service life limits, and whether the component is a retirement item or overhaul item. The major individual part or assembly which often has a scheduled or historical removal interval. The general categories of airframe components are: rotor blades, transmissions, flight controls, rotor heads, hydraulic systems and their driveshafts, major engine components and the engine themselves, along with their major controls.

Hourly Maintenance Cost (HMC) is the expense of running a helicopter’s major components for one hour. The HMC includes the parts and labor required for scheduled and unscheduled helicopter maintenance and helicopter inspections that are performed every twenty-five flight hours or greater. Maintenance intervals less than twenty-five flight hours are not considered.

HMCs are determined by computing the cost of each helicopter major-drive train component’s overhaul and retirement interval, with its associated labor costs, then dividing that sum by its allowable flight hours. The resulting per-hour costs are then totaled. HMCs are given as a range due to the variation of parts costs, transportation and labor charges, and discounts. Operators that do not employ in-house certificated maintenance technicians will likely have a higher HMC.
