40596 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.

The authority citation for these 

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 

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.

SUPPLEMENTARY INFORMATION: 

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. 

The Rule 

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.
