Federal Register / Vol. 76, No. 132 / Monday, July 11, 2011 / Rules and Regulations
finds that the test time associated with
the continuous OEI rating is an
appropriate baseline to define
additional requirements for this new
normal use 30- minute AEO rating.
Therefore, engine durability using this
rating must be demonstrated over and
above the takeoff rating and other
normal use ratings included in the
rating structure. No changes to the
special conditions have been made in
this regard.
The commenter also states that the 25
hour requirement is inconsistent with
§ 33.87 philosophies, stating that time at
any rating validates any lower rating.
This statement is incorrect. The test
requirements are established to
demonstrate engine durability at all
normal and emergency ratings and
associated limits. The test profiles
incorporate specific elements to this
end. The normal ratings all have
individual elements that must be
performed. The 30-minutes AEO rating
is a normal use rating that is expected
to be used with a frequency of
occurrence similar to the takeoff or
maximum continuous ratings, and must
have a specific and independent
element as part of the overall test. Also,
the expectation is that 30-minute AEO
will be used far more frequently than
any emergency 0E1 rating. These
emergency ratings must also be
demonstrated (when applicable)
however due to their limited use, these
elements of the test may overlap certain
normal rating elements found in the
various test profiles. The practice
mentioned by the commenter is applied
to OEI ratings only, because they are
rarely used and only in emergency
situations. Therefore, the frequency of
occurrence for normal use ratings
dictate that specific test time be
allocated to each rating, and that time
can’t be combined because a rating is
higher than another. No changes to the
special conditions have been made in
this regard.
The commenter also states that the
basis for 25 hours of required run time
was not described in the special
condition. The 25 hours was selected to
be between the basic cumulative run
time for takeoff rating (18.75 hours) and
maximum continuous rating (45 hours).
This requirement is weighted more
heavily toward the takeoff time due to
the severe nature of the rating and
intended operation. Therefore, no
changes to the special conditions have
been made in this regard.
Applicability
These special conditions are
applicable to the PWC PW210S turbo

shaft engine. If PWC applies later for a
change to the type certificate to include
another closely related model
incorporating the same novel or unusual
design feature, these special conditions
may also apply to that model as well,
and would be made part of the
certification basis for that model.
Conclusion
We reviewed the available data,
including the comment received, and
have determined that air safety and the
public interest require adopting this
special condition with the changes
described above. This action affects only
certain novel or unusual design features
on one model of engine. It is not a rule
of general applicability, and it affects
only the applicant who applied to the
FAA for approval of this feature on the
engine product.

special conditions is as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701–
44702, 44704.
The Proposed Special Conditions
Accordingly, the Federal Aviation
Administration (FAA) issues the
following special conditions as part of
the type certification basis for the PWC
PW210S turbo shaft engine.
1. PART 1 DEFINITION. Unless
otherwise approved by the
Administrator and documented in the
appropriate manuals and certification
documents, the following definition
applies to this special condition: ‘‘Rated
30 Minute AEO Power’’, means the
approved shaft horsepower developed
under static conditions at the specified
altitude and temperature, and within
the operating limitations established
under part 33, and limited in use to
periods not exceeding 30- minutes each.
2. PART 33 REQUIREMENTS.
(a) Sections 33.1 Applicability and
33.3 General: As applicable, all
documentation, testing and analysis
required to comply with the part 33
certification basis, must account for the
30-minute AEO rating, limits and usage.
(b) Section 33.4, instructions for
continued airworthiness (ICA). In
addition to the requirements of § 33.4,
the ICA must:
(1) Include instructions to ensure that
in-service engine deterioration due to
rated 30-minute AEO power usage will
not be excessive, meaning that all other
approved ratings are available within
associated limits and assumed usage, for
successive flights; and that deterioration
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
will not exceed that assumed for
declaring a time between overhaul
(TBO) period.
(i) The applicant must validate the
adequacy of the maintenance actions
required under paragraph (b)(1) above.
(2) Include in the airworthiness
limitations section (ALS), any
mandatory inspections and
serviceability limits related to the use of
the 30-minute AEO rating.
(c) Section 33.87, Endurance Test. In
addition to the requirements of
§§ 33.87(a) and 33.87(d), the overall test
run must include a minimum of 25
hours of operation at 30-minute AEO
power and limits, divided into periods
of 30-minutes AEO power with alternate
periods at maximum continuous power
or less.
(1) Modification of the § 33.87 test
requirements to include the 25 hours of
operation at 30- minute AEO power
rating must be proposed by the
Applicant and accepted by the FAA.
(2) Each § 33.87(d) continuous oneengine-inoperative (0EI) rating test
period of 30-minutes or longer, run at
power and limits equal to or higher then
the 30-minutes AEO raring, may be
credited toward this requirement. Note
that the test time required for the takeoff
or other OEI ratings may not be counted
toward the 25 hours of operation
required at the 30-minute AEO rating.

SUMMARY:
History
On April 12, 2011, the FAA published
in the Federal Register a notice of
proposed rulemaking to amend Class E
airspace for Madison, SD, creating
controlled airspace at Madison
Municipal Airport (76 FR 20279) Docket
No. FAA–2011–0135. Interested parties
were invited to participate in this
rulemaking effort by submitting written
comments on the proposal to the FAA.
No comments were received. Class E
airspace designations are published in
paragraph 6005 of FAA Order 7400.9U
dated August 18, 2010, and effective
September 15, 2010, which is
incorporated by reference in 14 CFR

Part 71.1. The Class E airspace
designations listed in this document
will be published subsequently in the
Order.
List of Subjects in 14 CFR Part 71
The Rule
Adoption of the Amendment
This action amends Title 14 Code of
Federal Regulations (14 CFR) Part 71 by
creating additional Class E airspace
extending upward from 700 feet above
the surface for new standard instrument
approach procedures at Madison
Municipal Airport, Madison, SD. This
action is necessary for the safety and
management of IFR operations at the
airport. Geographic coordinates are also
being updated to coincide with the
FAA’s aeronautical database.
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. Therefore, this regulation: (1) Is
not a ‘‘significant regulatory action’’
under Executive Order 12866; (2) is not
a ‘‘significant rule’’ under DOT
Regulatory Policies and Procedures (44
FR 11034; February 26, 1979); and (3)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. Since this is a
routine matter that will only affect air
traffic procedures and air navigation, it
is certified that this rule, when
promulgated, will not have a significant
economic impact on a substantial
number of small entities under the
criteria of the Regulatory Flexibility Act.
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the U.S. Code. Subtitle 1,
Section 106, describes the authority of
the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more
detail the scope of the agency’s
authority. This rulemaking is
promulgated under the authority
described in Subtitle VII, Part A,
Subpart I, Section 40103. Under that
section, the FAA is charged with
prescribing regulations to assign the use
of airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the
scope of that authority as it amends
controlled airspace for Madison
Municipal Airport, Madison, SD.
In consideration of the foregoing, the
Federal Aviation Administration
amends 14 CFR Part 71 as follows:
