Certification Basis CAR 6, dated December 20, 1956, including amendments 6-1 through 6-4 
and Special Conditions, "Conditions Establishing Compensating Factors 
Providing an Equivalent Level of Safety under Civil Air Regulations, 
Section 6.10 for Light Turbine Powered Helicopters", dated October 2, 
1962, except condition 15a.  Type Certificate H2WE issued May 22, 1964.  
Date of application for Type Certificate November 13, 1961. 
 
  
FAA Exemption No. 596 issued October 18, 1966, grants exemption from 
FAR 6.328 to the extent necessary to permit the Type Certification of The 
Fairchild Hiller Model FH-1100 without the necessity of considering the 
jamming of a control valve or the cracking of the actuator cylinder as 
possible failures. 
 
Production Basis None.  Prior to original certification of each aircraft manufactured 
subsequent to April 20, 1994, an FAA representative must perform a 
detailed inspection for workmanship, materials, and conformity with the 
approved technical data and a check of the flight characteristics. 
 
Equipment The basic required equipment as prescribed in the applicable airworthiness 
regulations (See certification basis) must be installed in the helicopter for 
certification.  Hiller Report 63-96, "Master Equipment List, Model 1100" 
and Hiller Report 66-19 "Basic Weight Equipment List", Model FH-1100, 
contain a list of all required equipment that must be installed as well as 
optional equipment installations approved by the FAA. 
 
NOTE 1 Current weight and balance report, including list of equipment included in certificated empty 
weight, and loading instructions must be in each helicopter at the time of original certification and 
at all times thereafter (except in the case of operators having an approved weight control system).  
Ballast, when necessary, must be carried in accordance with Loading Instructions in the FAA 
Approved Rotorcraft Flight Manual.  Fuel and Oil capacities as indicated are total tank capacities 
over and above "Trapped Fuel and Oil".  The fuel tank capacity includes "Unusable" fuel of 2.5 
gallons, for Model 1100 and 1.6 gallons (10.8 lbs.) for Model FH-1100 which cannot be used 
safely in all normal expected flight attitudes and must be included in the empty weight. 
 
NOTE 2 The following placard must be installed in clear view of the pilot: 
 
"This Helicopter must be operated in compliance with the operating limitations specified in the 
FAA Approved Rotorcraft flight Manual". 
 
For additional placards, see the FAA Approved Flight Manual. 
 
NOTE 3 The retirement times of critical parts are listed in the following tables.  These values of retirement 
of service life cannot be increased without FAA Engineering approval.

There is not a Rotorcraft Maintenance Manual for the Model 1100 helicopter.  Prior to civil 
airworthiness certification of the Model 1100 the applicant must prepare a rotorcraft Maintenance 
Manual containing all information essential for proper maintenance. 
 
The Model FH-1100 helicopter(s) must be serviced, maintained in accordance with instructions 
specified in the Model FH-1100:  Service Manual, Inspection Guide, Structural repair Manual, and 
Overhaul Manual or Instructions for Continued Airworthiness for type design changes or other 
methods, techniques and practices acceptable to the Administrator. 
 
NOTE 5 Prior to issuance of FAA Certificate of Airworthiness for Model 1100 (Military Model OH-5A) 
helicopters, conformance with the approved Type Design Data must be established, including 
modifications for the commercial approved equivalent in accordance with Hiller Aircraft Corp. 
Engineering Report 64-54, "Deviation Report, Model 1100 Helicopter (Army OH-5A)".
