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

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
date of approval of the certificate,
whichever 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, 2007,
June 7, 2010, or the date of approval of
the certificate, whichever occurs later.

(e) Each person identified in para-

graphs (d)(1), (d)(2), and (d)(4) of this
section must submit to the responsible
Aircraft Certification Service office for
approval a compliance plan by March
10, 2008. The compliance plan must in-
clude the following information:

(1) A proposed project schedule, iden-

tifying all major milestones, for meet-
ing the compliance dates specified in
paragraph (d) of this section.

(2) A proposed means of compliance

with this section, identifying all re-
quired submissions, including all com-
pliance items as mandated in part 25,
Appendix H paragraphs H25.5(a)(1) and
(b) of this subchapter in effect on De-
cember 10, 2007, and all data to be de-
veloped to substantiate compliance.

(3) A proposal for submitting a draft

of all compliance items required by
paragraph (e)(2) of this section for re-
view by the responsible Aircraft Cer-
tification Service office not less than
60 days before the compliance time
specified in paragraph (d) of this sec-
tion.

(4) A proposal for how the approved

ICA will be made available to affected
persons.

(f) Each person specified in paragraph

(e) must implement the compliance
plan, or later approved revisions, as ap-

proved in compliance with paragraph

imum takeoff gross weight greater
than 75,000 pounds and a type certifi-
cate issued after January 1, 1958, re-
gardless of whether the maximum
takeoff gross weight is a result of an
original type certificate or a later de-
sign change. This section also applies
to transport category, turbine-powered
airplanes with a type certificate issued
after January 1, 1958, if a design change
approval for which application is made
after January 14, 2011 has the effect of
