ACTION: Technical amendment;
correction.
AGENCY:
The FAA is correcting a
technical amendment published on July
5, 2012 (77 FR 39623). In that technical
amendment, the FAA clarified aircraft
engine vibration test requirements in the
airworthiness standards. The technical
amendment was in response to inquiries
from applicants requesting FAA engine
type certifications and aftermarket
certifications, such as supplemental
type certificates, parts manufacturing
approvals, and repairs. We revised the
regulation to clarify that engine surveys
require an engine test. Representatives
of industry suggested that our technical
amendment was in fact, a substantive
change in the regulation, not a
clarification. The FAA is correcting our
prior action in response to that industry
claim. This document amends the
FAA’s regulations to reverse the changes
to § 33.83(a) amendment 33–33 and
restore § 33.83(a) to its previous
amendment 33–17.
DATES: This corrective action becomes
effective September 20, 2012.

SUMMARY:
VerDate Mar<15>2010
15:06 Sep 19, 2012
Jkt 226001
On July 5, 2012, the FAA published
a Technical Amendment entitled,
‘‘Airworthiness Standards: Aircraft
Engine’’ (77 FR 39623). In that technical
amendment, the FAA intended to clarify
vibration test requirements in § 33.83 of
14 Code of Federal Regulations Part 33.
By letter dated August 3, 2012, the
Modification and Replacement Parts
Association (MARPA) asserts that the
rule appears to be a substantive change
that should have been open to public
comment. The MARPA further asserts
that had the rule been open for
comment, it and others would have
commented that the technical
amendment undermines the existing
regulatory system, rather than
improving it, and that it imposes
unnecessary burdens on the applicant
and the government with no
commensurate safety benefit. We do not
agree with MARPA’s assertion that the
rule change was substantive. However,
in the interest of transparency in the
rulemaking process, we are changing the
language of § 33.83(a) amendment 33–33
back to the language in § 33.83(a) of the
previous amendment 33–17.

§ 33.83
Vibration test.
(a) Each engine must undergo
vibration surveys to establish that the
vibration characteristics of those
components that may be subject to
mechanically or aerodynamically
induced vibratory excitations are
acceptable throughout the declared
flight envelope. The engine surveys
shall be based upon an appropriate
combination of experience, analysis,
and component test and shall address,
as a minimum, blades, vanes, rotor
discs, spacers, and rotor shafts.
