(1) Dimensionally check main rotor blade retention
bolt hole for indications of permanent deformation or damage. If
inside diameter of bushing in the hole is elongated in excess of
0.0015 inch (0.0381 mm), remove blade from service and return
it to a Bell Helicopter Textron approved major overhaul facility
for further inspection. Any evident looseness of bushing is
cause for scrapping blade.
(2) Remove tip cap assembly from main rotor blade
and inspect tip cap attaching screws for deformation. Any
deformation of screws or elongation of mating holes in the spar
is cause for scrapping blade.
(3) Visually inspect main rotor blade for skin wrinkles
or deformation. If any indication of wrinkles or deformation
exists, return blade to a Bell Helicopter Textron approved major
overhaul facility for evaluation.
(4) If main rotor blades pass the previous inspection,
they are acceptable for continued service.
c. Tail rotor blades.
(1) If one of the tail rotor blades of a pair has been
damaged badly enough that metal has been torn or any bond
plies have separated, then both blades and tail rotor hub must
be scrapped.
(2) If contour of a blade has been damaged slightly
(distortion) then both blades and tail rotor hub must be
scrapped.
(3) If any movement of the tip block or root end
balance weights has occurred, scrap tail rotor hub assembly
and both tail rotor blades.
(4) If tip block is cracked, scrap tail rotor hub assembly
and both tail rotor blades.
(5) If tail rotor blades pass the above inspection
requirements and no other discrepancies exist, the blades are
acceptable for continued service.
