Whirlwind Aviation recommends that maintenance and repair of Whirl Wind propellers only be performed by Whirlwind Aviation or Whirl Wind authorized service centers.
Our goal is continuous product improvement and as such we want to service as many of our propellers as possible. This provides valuable data on the life and performance of the materials and components used in every Whirl Wind propeller. We understand, however, that geographic separation may not make it practical to return your propeller to Whirl Wind for service. Visit our distributors page for a complete list of authorized U.S. and international service centers.
WARRANTY CLAIMS:Required service that falls within the Whirl Wind standard warranty period must be coordinated with Whirlwind Aviation. In consideration of a warranty claim Whirl Wind should, whenever possible, perform suspected warranty service so a proper investigation can be completed with respect to our specific manufacturing specifications. As stated above, if time will not allow for the propeller's return to Whirl Wind please contact Whirl Wind in advance of service by an unauthorized service center or certified mechanic.

Upon inspection, if we find additional replacement parts not listed above are required we will contact the owner in advance of completion of the repair to discuss costs and alternatives.

Service intervals are based on operating time (hours) or calendar time (years), whichever comes first. Please contact Whirlwind Aviation for current service prices.
