7. MAINTENANCE AND SERVICING
The MD 600N helicopter was designed for ease of supportability and low-cost operation.
Helicopter systems and components are easily accessed and can be maintained at the lowest
maintenance level possible. The helicopter was designed for a high level and ease of replacement
of line replaceable units (LRUs). The helicopter can be maintained at the line- / shop-
maintenance level using common hand tools, as well as easy to understand technical
publications. The MD 600N helicopter spare parts are readily available, and most parts have a
corresponding U.S. Department of Defense National Stock Number (NSN).
7.1 Maintenance
The MD 600N design provides for the maximum maintenance support at the lowest maintenance
level. The MD 600N can be maintained using a combination of line- and shop-maintenance
support. Components such as engine, avionics, interior components, air-conditioning, etc., are
considered LRUs. Line replaceable units (and any sub-component shop replaceable units) can be
removed and replaced easily and modularly, as necessary, and at the lowest maintenance level
allowed.
Typical for small- to mid-sized helicopter systems are fixed time-between-overhaul (TBO)
intervals for the engine, transmission, main rotor, and flight controls. Within these items are also
life-limited components that must be monitored and replaced at the end of life hours. When
required, components requiring further maintenance action can be removed and forwarded to the
appropriate-level shop.
The MD 600N helicopter airframe uses an on-condition maintenance concept, which allows
scheduled inspections / checks. To be compliant with commercial regulatory requirements, an
MD 600N continued airworthiness inspection program was developed by MDHI. This program
provides for schedule inspections, and also includes life-limited component replacement. The
maintenance and inspection intervals are provided in the Handbook of Maintenance Instruction.
Airframe-related inspection intervals occur every:
100 hours
300 hours
600 hours
1200 hours
Yearly
Special time-phase inspections.
The engine also has life-limited components, a fixed TBO, and inspection intervals. The MD
600N life-limited parts, overhaul intervals, and inspection intervals are listed in the table below.
