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
