GENERALA company manual should enable the operator's maintenance personnel to carry out their duties at a high level of safety. The complexity of the manual will vary with the complexity of the operation. The manual should cover specific items in accordance with the applicable Regulations, but may include additional items at the discretion of the applicant.

GENERAL A manual containing more than required information is therefore accepted rather than approved.

Inspectors should be concerned primarily with regulatory compliance.

GENERALThe manual is an administrative tool used to control and direct personnel. It should define all aspects of the maintenance operation. (1) The policies and procedures section should address organizational matters. (2) The maintenance section should address policies and procedures for administering the inspection and maintenance requirements

GENERALThe manual should include detailed instructions for accomplishing inspection and maintenance functions. It should also include forms, instructions, and references for recurring non-routine requirements.
