INTERMEDIATE PREVENTIVE MAINTENANCE CHECKS AND SERVICES
Intermediate PMCS shall be performed once every intermediate interval. An intermediate interval is
defined as approximately 25 flight-hours. The intermediate PMCS performed on the radio set shall be
performed concurrently with the aircraft intermediate PMCS. Intermediate intervals can be adjusted to
compensate for unusual operating conditions. Equipment maintained in a standby (ready for immedi-
ate operation) condition must have intermediate maintenance performed at least once every 30 days.
Equipment in limited storage (requires service before operation) does not require maintenance.
Check ground straps and shock isolators for security of attach-
ment and check shock isolators for smooth operation.

authorized crewmember will start and operate engines. If
aircraft engines are not operated, use an auxiliary power
