as critical as the specific ice accretion defined for that flight phase. Configuration differences and their effects on ice accretions
must be taken into account.
(f) The ice accretion that has the most adverse effect on handling qualities may be
used for airplane performance tests provided
any difference in performance is conservatively taken into account.

Subpart A - General
Section 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.
