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.
Blade angle
allowed
range (°)
TBO- Time Between
Overhaul*
(hour)
ROTAX 912S
ROTAX 912iS
ROTAX 914
* 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).
