Airworthiness limitations section.

The Instructions for Continued Airworthiness must contain a section titled Airworthiness Limitations that is segregated and
clearly distinguishable from the rest of the
document. This section must set forth each
mandatory replacement time, structural inspection interval, and related structural inspection procedure required for type certification. If the Instructions for Continued Airworthiness consist of multiple documents,
the section required by this paragraph must
be included in the principal manual. This
section must contain a legible statement in
a prominent location that reads  - The Airworthiness Limitations section is FAA approved and specifies maintenance required
under SectionSection 43.16 and 91.403 of Title 14 of the Code
of Federal Regulations unless an alternative
program has been FAA approved. -
