1. Presentation of the Certified FLASH-R propeller

Description1.1.

The certified FLASH-R propeller has a new innovative design,

specific about its twisting axis and center of pressure.

Its aerodynamic design allows a "Constant Speed" effect, limiting

variations in engine speed between on ground and in flight.

This propeller allows high efficiency throughout the flight envelope i.e.:

Improved takeoff and climb rate due to higher engine speed, then higher engine efficiency

Many cruise extension

A high user comforts

The blades and the hub of the FLASH-R propeller are manufactured according the DUC Hélices company

technologies, from unidirectional layers of carbon fibers prepreg epoxy resin.

The blade composite structure is defined to obtain the maximum strength in torsion and bending. Therefore

"constant speed" effect is not related to deformation of the blade but its geometry and specific profile.

Due to its specific geometric definition, excellent performance is obtained in both aerodynamic and acoustic,

but also in consumption.

Characteristics1.2.

The Certified FLASH-R propeller range is available:

Ground adjustable propeller

Tractor configuration available in right rotation

Diameters Ø1520 to Ø1900mm (Ø59.8 to Ø74.7")

Shielded leading edge in Inconel®

Carbon composite hub with metallic inserts

Protected again lightning strike

Direct assembly on the propeller-shaft Ø101.6mm

Safety marking on the tip of the propeller

Shielding leading edge in Inconel®1.3.

The leading edge of the Certified FLASH-R blades is equipped with a metallic shielding in Inconel®. This material is a

superalloy containing mainly nickel, with a very high hardness of surface.

Accessories1.4.

Aluminum mounting spacer (Direct mounting on P.C.D Ø101.6mm/Ø4”)

Moves the plane of the propeller to adjust the position according the engine hood

Aluminum adaptor spacer (Other mounting as SAE1, SAE2, …)

Move the propeller plane and adaptor the P.C.D fixation of the propeller

Spinner available in diameter Ø250mm (Ø9.8") to Ø340mm (Ø14.4”)

Adjusting tool for the setting of the pitch angle of the blades

Neoprene cover protection of the blade

Cleaning treatment for composite propellers

Save money! A clean propeller is more efficient and decreases the fuel consumption.

2. Applications

DUC propellers are given for a flight potential under normal operating conditions. To maintain this potential, DUC

Propellers has determined a TBO (time between revisions) for a propeller based on the engine it equips. See the

section 7.1 Airworthiness Limitations for Information Benefit.

* It is the maximum period of propeller use allowed by propeller type certificate.

Compliance with CS-P, Subpart D has not been demonstrated as part of the propeller certification.

Remark

The values of the pitch angle are defined by flight test on each engine. If necessary, this setting should be adjusted

according to the aircraft.

For proper use of the propeller, refer to section 7.Continuing airworthiness

3. Installation precautions

WARNING

Make sure the ignition is turned off before starting any type of operation on the propeller.

Do not run the engine without propeller, engine damage will result

IMPORTANT

The blades of a propeller are part of a whole. DO NOT INTERCHANGE with other similar blades from propeller. The

propeller blades are manufactured to their application. Their structure, weight and balance are different from a propeller

to another.

The spinner is an important element for cooling the engine. The aircraft must not fly without a spinner.

Fitting a different spinner will be an addendum to this manual approved by the DUC to confirm its compatibility with the mounting of

the propeller.

The propeller is delivered with the appropriate screws. The change of the screws is contrary to our recommendations unless

validated by the manufacturers.

WARRANTY CONDITIONS

The user is still flying under its full responsibility (see.8.General terms of sale).

5. Assembly instruction of the propeller

The assembly of the Three-blade Certified FLASH-R propellers is shown below. It is recommended to assemble the

propeller on a worktable before installing it on the plane.

For further information, contact the DUC Hélices Company.

Assembly of the propeller5.1.

A « Propeller Form » will be done to insure a propeller follow-up. Parts Number and component serial number of

propeller will be written on this form.

STEP

Place the rear half-hub on a worktable.

Be careful not to invert with the front hub half.

Depending on your installation, the rear half-hub is one

mounted on the propeller-shaft of the engine or on a

spacer. The diameter of the bore of the metal inserts of

the rear half- hub is larger than the bore of the metal

inserts of the front half-hub.

STEP

Place the hub spacer in the center of the rear half-hub.

STEP

Positioning the blades in their hub slots by placing them

outwards.

The three blades of the propeller have been

balanced at DUC Helices before their dispatch.

Position the DUC Hélices logo facing you.

Note that the metal inserts of the half-hub allow a

locking of the blades in their axis within the hub.
