VOLUME 3 General technical administration
chapter 32 MANUALS, PROCEDURES, AND CHECKLISTS FOR 14 CFR PARTS
Section 10 Safety Assurance System: Evaluate a Maintenance Manual/Revision for a Part
§ 135.411(a)(1) Program
3-3351 REPORTING SYSTEM(S). Use Safety Assurance System (SAS) automation and the associated Data Collection Tools (DCT).
3-3352 OBJECTIVE. Title 14 of the Code of Federal Regulations (14 CFR) part
each certificate holder, other than one who uses only one pilot in the certificate holder’s operations, to prepare and keep current a manual setting forth
the certificate holder’s procedures and policies acceptable to the Administrator. This section provides guidance for evaluating a certificate
holder/applicant’s manual or revision to ensure that policies, procedures, and technical criteria meet regulatory requirements. This section applies to
part 135 certificate
holders who maintain their aircraft under §
A. General Considerations. The manual should enable the certificate holder/applicant’s maintenance and servicing 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 must cover specific
items in accordance with 14 CFR, but may include additional items at the discretion of the certificate holder/applicant. A manual is therefore accepted rather than approved.
B. Manual Acceptance. Manual acceptance can cause a delay in the certification process. If the certificate holder/applicant does
not have experienced and qualified personnel to prepare an acceptable manual, using a consultant may be appropriate. A consultant can be used in an advisory position
only. After the review, the manual must be returned to the certificate holder/applicant with a list of any discrepancies found. The certificate holder/applicant must
be informed that final certification will not be completed until discrepancies are corrected. Aviation safety inspectors (ASI) should be concerned primarily with
ensuring regulatory compliance.
C. Debrief Certificate Holder/Applicant.
1) If discrepancies were noted, notify the certificate holder/applicant to resolve them.
2) If acceptance of a certificate holder’s manual is to be accomplished, there are various means to include, but not limited to,
a letter to the certificate holder or by taking no action. By taking no action, this indicates that there is no FAA objection to the proposal.
3-3354 REVIEWING CERTIFICATE HOLDER/APPLICANT’s MANUAL.
A. Manual’s Purpose. The manual is an administrative tool used to control and direct personnel. It should define all
aspects of the maintenance operation, including organizational structure.
B. Manual’s Content. The manual should include detailed instructions or specific references for accomplishing inspection and
maintenance functions, ground and flight operational check requirements, and other subjects as applicable. It should also include forms, instructions, and references
for recurring nonroutine requirements, such as engine changes and inspections following abnormal occurrences (hard landings, lightning strikes, severe turbulence,
high brake energy stops, etc.).
C. Technical Manuals. Manufacturers’ technical manuals provide instructions for accomplishing specific tasks. These documents
also establish methods, technical standards, measurements, and operational test procedures. The policy and procedures section of the certificate holder’s manual
must describe areas of application for the pertinent technical documents.
D. Manual Sections. The following is a list of examples of manual sections and titles the certificate holder may use:
• General policy and procedures,
• Inspection procedures,
• Maintenance procedures,
• Structural repair,
• Manufacturers or vendors,
• Weight and Balance (W&B) control, and
E. Revisions. Manuals should be easy to revise and show the date of last revision on each page. The manuals should have a page control
system showing the number of pages and including the latest revision. The page control system is usually identified as a list of effective pages.
F. Responsibility for Manual. The certificate holder/applicant is responsible for ensuring that their manuals contain adequate guidance
to meet all regulatory requirements. The certificate holder/applicant must understand and accept this responsibility early in the certification process.
3-3355 COORDINATION REQUIREMENTS. This task requires close coordination between principal maintenance, avionics, and in some areas, operations inspectors.
3-3356 REFERENCES, FORMS, AND JOB AIDS.
• Title 14 CFR Parts
• Title 49 of the Code of Federal Regulations (49 CFR) Part 173; and

B. Forms. None.
C. Job Aids. None.
A. Brief Certificate Holder/Applicant. Provide the certificate holder/applicant with policies and regulatory requirements. Schedule and
conduct a preliminary meeting, if necessary.
B. Review Schedule of Events (SOE). If this task is to be performed as part of an original certification, review the SOE to ensure that
the task can be accomplished on schedule.
C. Evaluate General Manual (GM) Requirements and Content. Ensure that the certificate holder/applicant’s policies and procedures
manual includes procedures, levels of authority, and information appropriate to part
1) Certificate Holder Philosophy and Goals. The manual should include a description introducing the certificate holder’s philosophy
and goals. If the manual is in more than one volume, it should describe the division of contents between the volumes. The manual should also contain a list of effective dates.
2) Manual Revision and Distribution. The manual must describe the revision control procedures and how the distribution of manuals will be
controlled (refer to §
The certificate holder’s procedures are required to provide current information to all manual holders. The manual should include provisions to make it available to
maintenance and ground personnel, and to furnish a copy to the Federal Aviation Administration (FAA) certificate-holding district office (CHDO) per §
Manuals should be easy to revise and have the date of the latest revision on each page. The manuals should have a page control system that shows the number of pages and ensures
that the latest revision is included. The page control system is usually identified as a list of effective pages (refer to §
The manual should detail requirements to carry the appropriate parts of the manual on the aircraft, if applicable, as required by §
3) Terms, Acronyms, or Abbreviations. Significant terms, acronyms, or abbreviations unique to the manual should be defined. Common industry
terms do not need to be defined if the common meaning is intended. Terms clearly defined in the text do not need to be included.
4) Organizational Elements. The names of all management personnel authorized to sign applicable operations specifications (OpSpecs) and act on
behalf of the certificate holder/applicant per 14 CFR part
