Care of A Wood Propeller

  •  Place the propeller in a horizontal position when parked.
  • Inspect frequently for bruises, scars, or other damage to wood and blade leading edge protection.
  • Protect your propeller from moisture by waxing with an automotive type paste wax.  Keep the drain holes in metal tipping clean.
  • Inspect and check propeller attaching bolts for tightness at least every 50 hours or annually.  More frequent inspection may be necessary when climatic changes are extreme. 
  • All wood and metal tipping repairs must be made at the factory or by an approved propeller repair station.  If your propeller was manufactured with synthetic leading edge protection, a kit is available from the factory for repair of damage to the leading edge. 
  • Check propeller balance whenever there is evidence of roughness on operation. 

If a Wood Propeller begins to show any of the following damage, it should be retired from service:

  • Cracks in hub bore
  • A long, deep wide crack parallel to grain
  • Oversize or elongated hub bore or bolt holes
  • An appreciable warp (discovered by inspection or through rough operation)
  • An appreciable portion of wood missing.
    A deep cut across wood grain. 
  • A separated lamination
  • Obvious damage or wear beyond economical repair.
