WARNING

Never reuse locking hardware. Reuse of locking hardware such as lockwashers,

locking nuts, cotter pins, and lockwire can result in undetected loosening of fas-

tening hardware causing catastrophic component failure resulting in death, in-

jury, or damage to equipment. In accordance with TB 43-0218, ensure that all

locking hardware is discarded upon removal and replaced with new.
