as critical as the specific ice accretion de-
fined for that flight phase. Configuration dif-
ferences and their effects on ice accretions
must be taken into account.

(f) The ice accretion that has the most ad-

verse effect on handling qualities may be
used for airplane performance tests provided
any difference in performance is conserv-
atively taken into account.

Subpart A—General

§ 26.1

Purpose and scope.

(a) This part establishes require-

ments for support of the continued air-
worthiness of and safety improvements
for transport category airplanes. These
requirements may include performing
assessments, developing design
changes, developing revisions to In-
structions for Continued Airworthiness
(ICA), and making necessary docu-
mentation available to affected per-
sons. 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

(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 air-
worthiness.

(4) Holders of type certificates and

their licensees producing new air-
planes.

sign change is not required to comply
with any applicable airworthiness re-
quirement 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 concur-
rently or after that airworthiness re-
quirement.

(d) For the purposes of this part, the

word ‘‘type certificate’’ does not in-
clude supplemental type certificates.

Subpart B—Enhanced Airworthi-

ness Program for Airplane
Systems

§ 26.11

Electrical wiring interconnec-

tion 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 pas-

senger 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 para-
graph (d) of this section must develop
Instructions for Continued Airworthi-
ness (ICA) for the representative air-
plane’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 re-
view and approval by the responsible
Aircraft Certification Service office.
For purposes of this section, the ‘‘rep-
resentative airplane’’ is the configura-
tion of each model series airplane that
incorporates all variations of EWIS
used in production on that series air-
plane, and all TC-holder-designed
modifications mandated by airworthi-
ness directive as of the effective date of

this rule. Each person specified in para-
graph (d) of this section must also re-
view any fuel tank system ICA devel-
oped by that person to comply with
SFAR 88 to ensure compatibility with
the EWIS ICA, including minimizing
redundant requirements.

type certificates and supplemental
type certificates, as identified in para-
graph (d) of this section, must:

(1) Evaluate whether the design

change for which approval is sought ne-
cessitates a revision to the ICA re-
quired by paragraph (b) of this section
to comply with the requirements of Ap-
pendix 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 responsible
Aircraft Certification Service 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 redun-
dant requirements between them are
minimized.

(d) The following persons must com-

ply 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 amend-

ments to TCs (including service bul-
letins describing design changes), if the
date of application was before Decem-
ber 10, 2007 and the certificate was
