Pt. 25 

(f) All data relative to structural fasteners 

such as identification, discard recommenda-
tions, and torque values. 

(g) A list of special tools needed. 
(h) In addition, for level 4 airplanes, the 

following information must be furnished— 

(1) Electrical loads applicable to the var-

ious systems; 

(2) Methods of balancing control surfaces; 
(3) Identification of primary and secondary

(4) Special repair methods applicable to 

the airplane. 

A23.4

Airworthiness limitations section. 

The Instructions for Continued Airworthi-

ness must contain a section titled Airworthi-
ness Limitations that is segregated and 
clearly distinguishable from the rest of the 
document. This section must set forth each 
mandatory replacement time, structural in-
spection interval, and related structural in-
spection procedure required for type certifi-
cation. If the Instructions for Continued Air-
worthiness 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 Air-
worthiness Limitations section is FAA ap-
proved and specifies maintenance required 
under §§ 43.16 and 91.403 of Title 14 of the Code 
of Federal Regulations unless an alternative 
program has been FAA approved.’’
