No. 2 2 2 2 P6BO Page 2 of 4 IMPORT REQUIREMENTS: To be considered eligible for installation on U.S. registered aircraft, each propeller to be exported to the United States shall be accompanied by a Certificate of Airworthiness for export endorsed by the UKCAA on behalf of the European Community which contains the following language: (1) This propeller conforms to its United States type design (TC No. P6BO) and is in a condition for safe operation. (2) This propeller has been subjected by the manufacturer to a final operational check and is in a proper state of airworthiness. Reference FAR Section 21.500 which provides for the airworthiness acceptance of aircraft engines or propellers manufactured outside the U.S. for which a U.S. type certificate has been issued. Additional guidance is contained in FAA Advisory Circular 21-23, Airworthiness Certification of Civil Aircraft, Engines, Propellers and Related Products, Imported into the United States. NOTES NOTE 1. Propeller Model Designation The model designation of a complete Dowty Propeller assembly consists of the basic model designation with prefix and suffix letters and numbers as shown below: P r e f i x B a s i c m o d e l d e s i g n a t i o n S u f f i x (c) R 381 / 6 -123 -F / -5 S u f f i x n u m b er denotes interchangeable design standard Engine Flange mounted Blade Shank size No. 123 N u m b e r o f b l a d e s - 6 Prefix number denotes non-interchangeable design standard D o w t y Civil (non-military) The prefix number indicates the design series, and propellers with different prefix numbers are not generally interchangeable. Certain models may be interchanged as complete aircraft sets on the advice of the propeller manufacturer only. The suffix number is used to record minor alterations which do not affect interchangeability NOTE 2. Blade Model Designation Dowty propeller blades are identified by a serialized part number only, which does not constitute a model designation. A dash number following the part number indicates the type of finish. NOTE 3: Pitch control: Normal pitch control from feather to full-reverse by pitch control unit (PCU). NOTE 4: (a) Feathering: (b) Reversing: Model incorporates auxiliary feathering and unfeathering features by means of counterweights and motor/pump unit, Model incorporates reversing feature. Page 3 of 4 P6BO NOTE 5: Right-hand model: (c) R.381 These propellers are designed and manufactured for right-hand tractor only. NOTE 6: Interchangeable blades: Only blades of the same part numbers are interchangeable and may be incorporated in the same propeller. NOTE 7: Accessories: (a) Propeller De-icing: Electrical de-icing with Dowty Brush Block Bracket Unit and Timer/Monitor Control Unit. NOTE 8: Drawings & Specifications: Design Specification 90DS0586 General Arrangement Drawing 697035101 Installation Drawing 697035001 The propeller equipment set, comprising the propeller itself and the units itemized below which are approved for use with the propeller are defined by Equipment Set Drawing 697031100 Issue 17 or subsequent approved issue and published in Aircraft Maintenance Manual (AMM) 1089. - Spinner - Feathering Pump - Overspeed Governor (OSG) - Beta Tube Assembly - Pitch Control Unit (PCU) - De-icing Equipment - Brush Block Bracket Unit - Timer/Monitor Control Unit Note 9: The Dowty Model (c)R.381/6-123-F/5 propelle r is controlled by an integrated control system which is part of the engine type design. The Model (c)R.381/6-123-F/5 propeller complies with the propeller airworthiness requirements when used with the Rolls-Royce Model AE2100A engine only. Any change to the engine, including its control system, which affects, or may affect, the propeller approval must be substantiated to demonstrate that the propeller as integrated with the changed engine, including its control system, still complies with the propeller certification basis. Also, any change to the engine, resulting from a change to the propeller, must be substantiated to demonstrate that the changed engine still complies with the engine certification basis. NOTE 10: Approved installations: Propellers listed in this data sheet are approved from a vibration standpoint only for use on the engine-aircraft combinations shown below: PROPELLER MODEL AIRCRAFT MODEL ENGINE MODEL FAA SPECIFICATION OR TC DATA SHEET AIRCRAFT ENGINE (c)R. 381/6-123-F/5 Saab 2000 Max.
