1. General

This chapter contains the Manufacturer
Recommended Inspection Program and
Maintenance Requirements for Continued
Airworthiness defined in accordance with
Federal Aviation Administration (FAA)
Federal Aviation Regulations (FAR) Part
91.409(f)(3). All scheduled inspections, special
inspections, component replacement and
overhaul schedules, unscheduled inspections
and maintenance tasks are designed to
preserve aircraft reliability and make sure the
continued airworthiness and safe operation of
the MD900 Series helicopter.
New inspection requirements, and changes to
existing inspection requirements, become
effective on the revision date of the change.
Unless otherwise noted, compliance of a new
or revised inspection requirement will be done
no later than the next scheduled interval of
the changed item, after receipt of the revision.
Unless otherwise noted, an inspection in
progress at the time a new revision becomes
effective, can be completed, utilizing the
inspection criteria in effect when the inspec­
tion was begun.
