A6EA 3
Production basis None. Prior to original certification of each aircraft 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.
Determine that all unmodified parts (parts built under the original Republic RC-3
Type Certificate No. 769) are in an airworthy and unaltered condition.
This determination may be accomplished by means of an examination of the
aircraft records, and to the extent possible, a visual inspection of the aircraft original
parts. Particular attention should be given to the following areas:
(1) The rudder spar at each of the rudder-fin hinges
(2) Both main landing gear (especially the actuating tube at the weld)
(3) The elevator torque tube fittings
(4) The hull fuel cells (for evidence of deterioration)
Any Republic Model RC-3 parts which may have been altered must be substantiated
by the applicant to the controlling region of the Republic Model RC-3 aircraft.
For information concerning the United Consultants Model UC-1 modification contact
the controlling region of the United Consultants Model UC-1 aircraft.
Equipment The basic required equipment as prescribed in the applicable airworthiness
regulations (see Certification Basis) must be installed in the aircraft for certification.
In addition, the following items of equipment are required:
(a) FAA approved Airplane Flight Manual
NOTE 1. Current weight and balance report including list of equipment included in certificated
empty weight, and loading instructions when necessary, must be provided for each
aircraft at the time of original certification. The certificated empty weight and
corresponding center of gravity location must include unusable fuel (included in main
tank capacity) of 9 lb. at (+116.0”) and system oil (not included in oil capacity) of 4 lb.
at (+101.9”)
NOTE 2. All placards required in the FAA approved airplane flight manual must be installed
in the appropriate locations.
NOTE 3. Airworthiness Directive 53-23-3 must be compiled with for original certification and at
the repetitive intervals as stated in the Airworthiness Directive.
