NOTES:
(1) Life − limited components interchanged between models or configurations must be restricted to the lowest
service life indicated for the models or configurations affected. Life − limited components removed at
retirement are to be mutilated/destroyed or conspicuously marked to prevent inadvertent return to service.
Parts are applicable only on models under which a service life is listed.
Life − limited components cannot be altered or permanently marked in any manner without compromising
the part integrity. Part tagging or other record keeping system is required.
Related component records must be updated each time component is removed from service.
(2) Service life shown for the basic (no dash number) part numbers apply to all dash numbered versions
unless otherwise indicated.
(3) With no cargo hook attached: − No retirement life assigned (Ref. Sec. 05 − 10 − 00, Component Overhaul or
Recommended Replacement Schedule).
With cargo hook attached and no separate log: − 1800 hours.
With cargo hook attached and with separate log: − 1800 hours of external load operating time when logged
separately.
(For 369D/E/F/FF helicopters with 369A5364 or 369D25351 sprag assembly, Refer to AD 90 − 19 − 02.)
(4) Inspect in accordance with Main Rotor Strap Pack Lamination Inspection at 100 − hour intervals, or 25 − hour
intervals if 2 laminates (369D/E/F/FF − 500N) or 1 laminate (600N) have failed in any one leg or tongue
area of any strap assembly. A single cracked laminate between the shoes at the outboard end of a strap
pack is cause for rejection of the hub assembly
369D/E/F/FF − 500N: (Ref. Sec. 62 − 20 − 00, Main Rotor Strap Pack Lamination Inspection).
600N: (Ref. Sec. 62 − 20 − 60, Main Rotor Strap Pack Lamination Inspection).

(5) The 369D21100 − 513, − 515, 516, 517 and − 523 main rotor blades are not interchangeable with any earlier
configuration blades (Basic, − 505 or − 509); however, the − 505 and − 509 blades are interchangeable and
the − 513 and − 515 blades are interchangeable. The − 505 and − 509 configuration blades may be modified
to the − 513M configuration, which is fully compatible with the − 513 blade. (For information concerning
modification, contact MDHI Customer Service Department.)
(6) For the 369D/E helicopters, the 369D21120 − 501, − 503 main rotor blade has all the same inspections and
interchangeability as the 369D21100 − 517 main rotor blade.
For the 369F/FF − 500N helicopters, the 369D21121 − 501, − 503 main rotor blade has all the same
inspections and interchangeability as the 369D21102 − 517 main rotor blade.
For the 600N helicopters, the 369D21121 − 501, − 503 main rotor blade has all the same inspections and
interchangeability as the 369D21102 − 523 main rotor blade.
