(10) The 369A1613-7, -9, and -11 tail rotor blades are for military use only (OH-6A) and are not 
FAA certified for Model 369H series helicopters. 
(11) These Blades are Subject Flight Hour Factoring. See applicable Service Bulletin SB369H -243R3, 
SB369D-195R3, SB369E-088R3 or SB369F-075R3, SB500N-015R3, SB600N-007R2 dated July 
13, 1998 and FAA AD 98-15-26. TE = Torque Events is defined as the transition to a hover from 
forward flight. For this definition of TE, Forward Flight is considered to be flight at any airspeed 
after attaining transitional lift. 
 
NOTE 4 The following information applies to the U.S. standard and export airworthiness certification  of Hughes 
Model 369 (YOH-6A) and 369A (OH-6A) helicopters: 
 a) The Hughes Model 369 (YOH-6A) and 369A (OH-6A) helicopters were only produced for and 
delivered to military customers. To meet the basic eligibility requirements for a U.S. standard 
and export airworthiness certificate, Hughes Model 369 (YOH-6A) and 369A (OH-6A) 
helicopters must have been issued an FAA Form 8130-2 (previously FAA Form 970), “FAA 
Conformity Certificate – Military Aircraft”, prior to delivery to the U.S. Army. Civil 
conversion of these helicopters requires certain modifications to be made in accordance with 
the applicable FAA approved type design data which forms the basis of Type Certificate  
H3WE. 
 b) Government furnished equipment identified in Hughes Report No. 369 -X-0008, dated June 24, 
1964 must be removed from Hughes Model 369 (YOH-6A) helicopters to be eligible for a U.S. 
standard and export airworthiness certificate. 
 c) The FAA approved parts and equipment identified as required in Hughes Report No. 369 -E-
5002, dated April 15, 1966 must be installed on Hughes Model 369A (OH -6A) helicopters to be 
eligible for a U.S. standard and export airworthiness certificate. 
 d) Information essential to the proper maintenance of the Hughes Model 369A (OH-6A) 
helicopters is contained in the latest version of U.S. Army Technical Manual TM 55 -1520-214-
23 and is applicable to civil converted Hughes Model 369A (OH-6A) helicopters. However, 
civil conversion of these helicopters in accordance with the applicable NOTE 4.a) above will 
result in configuration changes to these helicopters which are not included in TM  55-1520-214-
23. 
Maintenance information associated with the configuration changes do es not exist and must be 
furnished and submitted, by the applicant for an airworthiness certificate, to the FAA Ft. Worth 
Aircraft Evaluation Group (FTW-AEG) for review and acceptance prior to issuance of a U.S. 
standard and export airworthiness certificate. See NOTE 3 and Service Life Limits section of 
this TCDS above for maintenance information and a list of life limited components for civil 
converted Hughes Model 369 (YOH-6A) and 369A (OH-6A) helicopters.

NOTE 14 NOISE CHARACTERISTICS.  Model 369D and 369E helicopters with the Rolls-Royce Corporation 
(formerly Allison Engine Company) 250-C20B engine installed have not been tested for noise in 
accordance with the requirements of FAR Part 36. Therefore, they are Stage 1 helicopters. Substitution 
of Rolls-Royce Corporation 250-C20R/2 engine results in no acoustic change. Thus, Model 369D and 
369E aircraft with the 250-C20R/2 engine installed are also Stage 1 helicopters.   
Model 369FF helicopter with the Rolls-Royce Corporation 250-C30 engine has been tested for noise and  
demonstrated compliance with the requirements of FAR Part 36, therefore, the Model 369FF is a Stage 2 
helicopter. 
The Model 500N has demonstrated compliance with FAR Part 36, Appendix H, through Amendment 
36-18, for Stage 2 helicopters.

VIII Data Pertinent to all Models (cont.) 
NOTE 15 (cont.) (1) These helicopters were built for foreign military and are not eligible for an FAA Certificate of 
Airworthiness (See NOTE 5). 
 
NOTE 16 For Model 600N, a current Weight and Balance Report (MDHS’ Basic Weight and  Balance Record) 
listing the helicopter certificated empty (basic) weight and loading instructions including a List of 
Equipment (MDHS’ MD-600N Required/Optional Equipment List is provided as a separate  document) 
must be provided for each helicopter at the time the helicopter’s original airworthiness certification is 
issued.  This Basic Weight and Balance Record shall be kept current as the configuration, affecting the 
helicopter’s weight and balance, is changed. The MDHS Basic Weights Checklist Record (Chart A) an d 
Basic Weight Checklist Supplement for the Model 600N contains needed reference data for the Weight 
and Balance Record. A copy of the current MDHS Basic Weight and Balance Record shall be kept in the 
helicopter. The certificated basic weight and corresponding center of gravity locations includes all 
transmission, hydraulic and engine oil/fluids as well as trapped/unusable fuel. 
NOTE 17 The model 600N rotorcraft employs electronic engine controls, commonly named  Full Authority Digital 
Engine Controls (FADEC) and is recognized to be more susceptible to Electromagnetic Interference 
(EMI) than rotorcraft that have only manual (non-electronic) controls (EMI may be the result of radiated 
or conducted interference.) For this reason modifications that add or change systems that have the 
potential for EMI, must either be qualified to an FAA acceptable standard or tested at the time of 
installation for interference to the FADEC. This type of testing must employ the particular FADEC’s 
diagnostic techniques and external diagnostic techniques. The test procedure must be FAA approved. 
NOTE 18 Extension of the basic fuel capacity over 148.1 US gal. (Main Fuel Tank – 114.6 US Gal, plus Fuel Tank 
- 33.5 US Gal) for the Model 600N may require reevaluation of the FADEC control system reliability 
due to time limited exposure determinations made during certification. 
NOTE 19 The Model 600N is prohibited from flying in falling or blowing snow with the standard  engine inlet 
screen installed. 
NOTE 20 
 
 
 
 
 
NOTE 21                   
Any changes to the type design of this helicopter by means of an amended type  certificate (TC), 
supplemental type certificate (STC), or amended STC, requiring instructions for continued airworthiness 
(ICA) must be submitted through the project aircraft certification office (ACO) for review and 
acceptance by the Fort Worth -Aircraft Evaluation Group (FTW-AEG) Flight Standards District Office 
(FSDO) prior to the aircraft delivery, or upon issuance of the first standard airworthiness certificat e for 
the affected aircraft, whichever occurs later as prescribed by Title 14 CFR § 21.50. Type design changes 
(major repairs or alterations) by means of a FAA Form 337 (field approval) that require ICA’s must 
have those ICA’s reviewed by the field approving FSDO. 
To operate in U.S. airspace, the following aircraft serial numbers are production equipped to meet the 
crash resistant fuel system certification basis requirements per section 44737 of Title 49 U.S.C.: Model 
369FF serial number (s/n) 0334FF and subsequent, Model 369E serial number 0626E and subsequent, 
and Model 600N s/n RN003 and subsequent.
