82-14-01 HUGHES: Amendment 39-4402. Applies to the Hughes Model 369 Helicopters with Chadwick C-20 Auxiliary Fuel System installed per Supplemental Type Certification SH129WE. Compliance is required as indicated, to provide early warning of auxiliary fuel transfer pump malfunction and the associated decrease in usable auxiliary fuel.

The placard installed per Item 1 above may be removed, provided the revised Flight Manual Supplement, Chadwick Auxiliary Fuel System C-20, dated October 21, 1981, is incorporated into the Rotorcraft Flight Manual.

3. Alternate modifications or other actions which provide an equivalent level of safety may be used when approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Mountain Region.
