NOTE 4. These Helicopters must be serviced and maintained in conformance with instructions given by Fairchild
Hiller Corporation, in the pertinent model inspection guide, repair handbook, and service and overhaul
manuals.
NOTE 5. Model UH-12E Helicopters (3 and 4 place configurations) may be converted to Model UH-12L or UH-12L4
by accomplishment of Hiller Service Bulletins No. 2040 (Dwg. 10060) or No. 2045 (Dwg. 10059)
respectively.
NOTE 6. The type certificate holder has demonstrated compliance with FAR 133.43 for the UH-12L and UH-12L4
Helicopters for Class B (Jettisonable Sling Load) Rotorcraft - load combination at a maximum overall weight
of 3500 pounds and a maximum sling load of 1000 pounds, when modified to incorporate cargo hook
installation per Hiller Dwg. 91012-23 (UH-12L4) and 91012-25 (UH-12L). The helicopter weight without
sling load is not to exceed certificated weight of 3100 pounds. For limitations see pertinent FAA Approved
Rotorcraft Flight Manual Revision and Rotorcraft - Load Combination Flight Manual to be submitted by
applicant for external load operator's certificate in accordance with FAR part 133.
NOTE 7. Certain part numbers used on this model helicopter may be used on other model helicopters in
which their use is life limited. These part numbers are listed in TCDS 4H11, H1WE, 4H10, 6H1,
and 6H2 and FAA approved Hiller Instructions for Continued Airworthiness. If a full and
complete service history from manufacture forward is not available that demonstrates these parts
were used only on a model helicopter for which the part is not life limited then those parts shall be
life limited to the lowest number of hours given in those TCDS’s or ICAs. If a full and complete
service history from the manufacturer forward is available, and any operating time has occurred in
a life limited model helicopter, that part shall be considered life limited at the lowest life limit
listed even if transferred and used on a helicopter model for which it is not life limited. Only those
parts for which a full and complete service history from manufacture forward is available and
which shows only operating time on a helicopter model for which it is not life limited are
considered not life limited.
