Operational Alert: 149
Date: June 4, 2001
Subject: Two-blade Warp Drive propellers on 100 HP 912S's
Compliance: Mandatory
Models Affected: S-6S, S-6SXL, S-6ES, S-6XL, S-7, S-9, S-10 with Rotax
912S Engine
It has been determined that the two-blade Warp Drive propeller is not
enough propeller to absorb the horsepower from the 912S. Even short-term
use may result in fractures at the hub end of the blades. It is
recommended to stop use of the two-blade propeller and replace it with
the three-blade Warp Drive or a two-blade Sensenich wood propeller. With
use of the three-blade Warp Drive a thorough inspection of the propeller
hub and blade roots is required every 25 hours. Please take action
before your next flight.
Thank you for your attention to this matter. Hopefully we have not
inconvenienced you to any great degree. Fly safe!
