5-3. CRASH DAMAGE
Because of the many possible combinations that can
result from crash damage, it is not possible to include
the specified repair schemes in this category. The
helicopter mechanic must make an analysis of the
crash damage for each situation. Do the repairs in
accordance with the degree of damage to the specific
part and the applicable repair instructions in this
manual. Call Bell Helicopter Textron Product Support
Engineering with your analysis of the crash damage.
5-4. TYPES OF INSPECTIONS
1. The maintenance procedures may include
scheduled inspections, special inspections, conditional
inspections, component interim inspections, and
component overhaul inspections.
a. Scheduled inspections must occur at specified
operating intervals. The intervals may be in operating
time (hours), cycles, torque events (R.I.N.), calendar
(days, months, years) or other assigned units. This
makes sure that the helicopter is airworthy.
b. Special inspections are of a temporary nature
or of a special interval not consistent with the
scheduled inspections.
c. Conditional inspections do not occur at a
specified time. They are based on known or suspected
unusual events, known or suspected malfunctions or
defects.
d. An interim inspection occurs between
overhauls.
e. The component overhaul schedule gives the
elapsed operating time at which a component must be
removed, disassembled, examined for condition, and
overhauled in accordance with data approved by Bell
Helicopter Textron.
