Flail Blades Inspection

Inspect the Blades daily for abnormal wear. REPLACE ALL BLADES on the carrier IMMEDIATELY if any blades have:

•Become bent or deformed from its original shape, or

•Wear inside the blade bolt hole, or

•Any cracks are visible, or

•Deep gouges in the blade’s surface are present, or

•Gouges or chipped areas in the cutting edge are larger than 1/4”(8mm), or

•The material on the leading edge has been worn away by more than 1/4”(8mm)

DO NOT straighten, sharpen, weld or hard-face blades

Failure to replace worn or damaged blades may lead to catastrophic failure of the blades and ejection of the broken part with tremendous force which may cause serious bodily injury or death.

Always replace blades in sets

•Blades that are damaged may indicate severe service or abuse. If one blade is worn or damaged other blades on the same shaft will have been subjected to the same severe service or abuse.

•The Flail rotor turns at speeds exceeding 2000 RPM and is dynamically balanced at the factory. Differ- ences in blade weight between used blades with loss of material from gouges or wear as compared to new blades can cause severe vibration and damage to the Flail rotor. Always replace blades as complete sets.
