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 FAA Over-
sight Office. For purposes of this sec-
tion, the ‘‘representative airplane’’ is
the configuration of each model series
airplane that incorporates all vari-
ations of EWIS used in production on
that series airplane, and all TC-holder-
designed modifications mandated by
airworthiness directive as of the effec-
tive date of this rule. Each person spec-
ified in paragraph (d) of this section
must also review any fuel tank system
ICA developed by that person to com-
ply with SFAR 88 to ensure compat-
ibility 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 FAA Over-
sight 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
issued on or after December 10, 2007:
December 10, 2009 or the date the cer-
tificate is issued, whichever occurs
later.

(3) Unless compliance with § 25.1729 of

this subchapter is required or elected,
applicants for 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 the date of applica-
tion was before December 10, 2007 and
the certificate was issued on or after
December 10, 2007: June 7, 2010, or the
