Subpart A—General
§ 26.1 Purpose and scope.
(a) This part establishes requirements for support of the continued airworthiness of and
safety improvements for transport category airplanes. These requirements may include
performing assessments, developing design changes, developing revisions to Instructions for
Continued Airworthiness (ICA), and making necessary documentation available to affected
persons. Requirements of this part that establish standards for design changes and revisions
to the ICA are considered airworthiness requirements.
(b) Except as provided in paragraph (c) of this section, this part applies to the following
persons, as specified in each subpart of this part:
(1) Holders of type certificates and supplemental type certificates.
(2) Applicants for type certificates and supplemental type certificates and changes to those
certificates (including service bulletins describing design changes).
(3) Persons seeking design approval for airplane repairs, alterations, or modifications that may
affect airworthiness.
(4) Holders of type certificates and their licensees producing new airplanes.
(c) An applicant for approval of a design change is not required to comply with any applicable
airworthiness requirement of this part if the applicant elects or is required to comply with a
corresponding amendment to part 25 of this chapter that is adopted concurrently or after that
airworthiness requirement.
(d) For the purposes of this part, the word “type certificate” does not include supplemental type
certificates.
§ 26.3 Definitions.
For the purposes of this part:
FAA Oversight Office is the aircraft certification office or office of the Transport Airplane
Directorate with oversight responsibility for the relevant type certificate, supplemental type
certificate, or manufacturer, as determined by the Administrator.
§ 26.5 Applicability table.

Subpart B—Enhanced Airworthiness Program for Aging Systems
§ 26.11 Electrical wiring interconnection systems (EWIS) maintenance program.
(a) Except as provided in paragraph (g) of this section, this section applies to transport
category, turbine-powered airplanes with a type certificate issued after January 1, 1958, that,
as a result of the original certification, or later increase in capacity, have—
(1) A maximum type-certificated passenger capacity of 30 or more or
(2) A maximum payload capacity of 7,500 pounds or more.
(b) Holders of, and applicants for, type certificates, as identified in paragraph (d) of this section
must develop Instructions for Continued Airworthiness (ICA) for the representative airplane's
EWIS in accordance with part 25, Appendix H paragraphs H25.5(a)(1) and (b) of this
subchapter in effect on December 10, 2007 for each affected type design, and submit those
ICA for review and approval by the FAA Oversight Office. For purposes of this section, the
“representative airplane” is the configuration of each model series airplane that incorporates all
variations of EWIS used in production on that series airplane, and all TC-holder-designed
modifications mandated by airworthiness directive as of the effective date of this rule. Each
person specified in paragraph (d) of this section must also review any fuel tank system ICA
developed by that person to comply with SFAR 88 to ensure compatibility with the EWIS ICA,
including minimizing redundant requirements.
(c) Applicants for amendments to type certificates and supplemental type certificates, as
identified in paragraph (d) of this section, must:
(1) Evaluate whether the design change for which approval is sought necessitates a revision to
the ICA required by paragraph (b) of this section to comply with the requirements of Appendix
H, paragraphs H25.5(a)(1) and (b). If so, the applicant must develop and submit the necessary
revisions for review and approval by the FAA Oversight Office.
(2) Ensure that any revised EWIS ICA remain compatible with any fuel tank system ICA
previously developed to comply with SFAR 88 and any redundant requirements between them
are minimized.
(d) The following persons must comply with the requirements of paragraph (b) or (c) of this
section, as applicable, before the dates specified.
(1) Holders of type certificates (TC): December 10, 2009.
(2) Applicants for TCs, and amendments to TCs (including service bulletins describing design
changes), if the date of application was before December 10, 2007 and the certificate was
issued on or after December 10, 2007: December 10, 2009 or the date the certificate is issued,
whichever occurs later.

amendments to TCs, if the application was filed on or after December 10, 2007: December 10,
2009, or the date of approval of the certificate, whichever occurs later.
(4) Applicants for supplemental type certificates (STC), including changes to existing STCs, if

occurs later.
(5) Unless compliance with §25.1729 of this subchapter is required or elected, applicants for
STCs, including changes to existing STCs, if the application was filed on or after December 10,

Subpart E—Aging Airplane Safety—Damage Tolerance Data for Repairs and Alterations
Source: Doc. No. FAA–2005–21693, 72 FR 70505, Dec. 12, 2007
§ 26.41 Definitions.
Affects (or Affected) means structure has been physically repaired, altered, or modified, or the
structural loads acting on the structure have been increased or redistributed.
Baseline structure means structure that is designed under the original type certificate or
amended type certificate for that airplane model.
Damage Tolerance Evaluation (DTE) means a process that leads to a determination of
maintenance actions necessary to detect or preclude fatigue cracking that could contribute to
a catastrophic failure. As applied to repairs and alterations, a DTE includes the evaluation both
of the repair or alteration and of the fatigue critical structure affected by the repair or alteration.
Damage Tolerance Inspection (DTI) means the inspection developed as a result of a DTE. A
DTI includes the areas to be inspected, the inspection method, the inspection procedures,
including acceptance and rejection criteria, the threshold, and any repeat intervals associated
with those inspections. The DTI may specify a time limit when a repair or alteration needs to be
replaced or modified. If the DTE concludes that DT-based supplemental structural inspections
are not necessary, the DTI contains a statement to that effect.
DT data mean DTE documentation and the DTI.
DTE documentation means data that identify the evaluated fatigue critical structure, the basic
assumptions applied in a DTE, and the results of a DTE.
Fatigue critical structure means airplane structure that is susceptible to fatigue cracking that
could contribute to a catastrophic failure, as determined in accordance with §25.571 of this
chapter. Fatigue critical structure includes structure, which, if repaired or altered, could be
susceptible to fatigue cracking and contribute to a catastrophic failure. Such structure may be
part of the baseline structure or part of an alteration.
Implementation schedule consists of documentation that establishes the timing for
accomplishing the necessary actions for developing DT data for repairs and alterations, and
for incorporating those data into an operator's continuing airworthiness maintenance program.
The documentation must identify times when actions must be taken as specific numbers of
airplane flight hours, flight cycles, or both.
Published repair data mean instructions for accomplishing repairs, which are published for
general use in structural repair manuals and service bulletins (or equivalent types of
documents).
§ 26.43 Holders of and applicants for type certificates—Repairs.
(a) Applicability. Except as specified in paragraph (g) of this section, this section applies to
transport category, turbine powered airplane models with a type certificate issued after

under paragraph (b)(1) of this section and §26.45(b)(2);
(ii) A process that will enable operators to obtain the DTI for repairs identified under paragraph
(e)(1)(i) of this section; and
(iii) An implementation schedule for repairs covered by the repair evaluation guidelines. The
implementation schedule must identify times when actions must be taken as specific numbers
of airplane flight hours, flight cycles, or both.
