AIRPLANE MAINTENANCE MANUAL

SCHEDULED MAINTENANCE CHECKS (CONT)
NOTES (CONT):
33.
For airplanes 15 years old or older, using a 10X magnifier, visually inspect the entire surface of each cable terminal, turnbuckle, or other cable fitting for corrosion or cracking. Any evidence of corrosion or cracking, however minute, is cause for replacement. A logbook entry documenting the replacement of a cable terminal, turnbuckle, or other cable fitting relieves the inspection requirement for that fitting only, until such time as that fitting has been in service for 15 years.

34.
For aircraft in normal operation, each 7 years; or, for aircraft in training operations, each 2000 hours time-in-service: remove interior panels and headliner and conduct detailed inspection of aircraft structure (skin, bulkheads, stringers, etc.) for condition and security. Inspection of structure concealed by headliner may be accomplished by alternate means (i.e. - through the use of a borescope) without removing the headliner, providing access is obtained to all concealed areas and borescope provides sufficient detail to adequately accomplish the inspection.

35.
Inspect seat belt and shoulder harness ends and attachment points for condition and security. Inspect harness web material for condition and wear over its entire length. Particularly look for wear and fraying where harness web passes in and out of adjustable buckle end and shoulder harness inertial reel. If excessively worn, replace. In S/N’s 4496001 thru 4496035 only, inspect shoulder harness keeper nylon bushing on the lap belt. If excessively worn or missing, replacement of that half of the lap belt is required.
