same or similar novel or unusual design 

feature, the special conditions would 

also apply to the other model. 

Novel or Unusual Design Features 

The Turbomeca model Ardiden 3K 

turboshaft engine will incorporate a 30- 

minute HIP rating, for use up to 30 

minutes at any time between take-off 

and landing. The 30-minute time limit 

applies to each instance the rating is 

used. However, there is no limit to the 

number of times the rating can be used 

during any one flight and there is no 

cumulative time limitation. These 

special conditions for a 30-minute HIP 

rating apply to address this novel and 

unusual design feature. 

Discussion of Comments 

A notice of proposed special 

conditions, Notice 33–12–02–SC for the 

Turbomeca model Ardiden 3K 

turboshaft engine was published on 

November 8, 2012 (77 FR 66936). We 

received no comments. 

Applicability 

These special conditions are 

applicable to Turbomeca model Ardiden 

3K turboshaft engines. If Turbomeca 

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 would apply to that 

model as well. This is true, if the 

certification basis is the same or 

contains later amendments that satisfy 

the certification basis discussed in the 

section titled ‘‘Type Certification Basis.’’ 

Conclusion 

We reviewed the available data and 

have determined that air safety and the 

public interest require adopting these 

special conditions as proposed. This 

action affects certain novel or unusual 

design features on the Turbomeca 

Model Ardiden 3K turboshaft engine. It 

is not a rule of general applicability, and 

applies only to Turbomeca, that 

requested FAA approval for these 

engine features.

special conditions continues to read as 

follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701– 

44702, 44704. 

The Special Conditions 

■ Accordingly, the FAA issues the 

following special conditions as part of 

the type certification basis for the 

Turbomeca model Ardiden 3K 

turboshaft engine. 

1. Part 1 Definitions 

Unless otherwise approved by the 

Administrator and documented in the 

appropriate manuals and certification 

documents, the following definition 

applies to these special conditions: 

‘‘Rated 30-Minute Hover at Increased 

Power (HIP),’’ 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. 

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 HIP 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 HIP usage will not be 

excessive, meaning that all approved 

ratings, including One Engine 

Inoperative (OEI), are available (within 

associated limits and assumed usage) for 

each flight; and that deterioration will 

not exceed that assumed for declaring a 

Time Between Overhaul period. 

(2) Validate the adequacy of the 

maintenance actions required under 

paragraph (b)(1) above. 

(3) Include in the Airworthiness 

Limitations section, any mandatory 

inspections and serviceability limits 

related to the use of the 30-minute HIP 

rating. 

(c) Section 33.29, Instrument 

Connection. The engine must have a 

means or a provision for a means, which 

alerts the pilot when the 30-minute HIP 

rating time limit has expired. 

(d) Section 33.87, Endurance Test. In 

addition to the applicable requirements 

of §§ 33.87(a), 33.87(d) and 33.87(e) (for 

engines that combine 2.5 minute and 

continuous OEI ratings): 

(1) The overall test run must include 

a minimum of 25 hours of operation at 

30-minute HIP rating and limits, 

divided into periods of not less than 30 

minutes but not more than 60 minutes, 

with alternate periods at maximum 

continuous power or less. 

(2) Each § 33.87(d)(3) continuous OEI 

rating test period of 60 minutes duration 

run at power and limits equal to or 

higher than the 30-minute HIP rating, 

may be credited toward this 

requirement. Note that you may not 

count the test time required for the 

takeoff or other OEI ratings toward the 

25 hours of testing required at the 30- 

minute HIP rating.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for General 

Electric Company (GE) CF34–8C and 

CF34–8E turbofan engines with certain 

part numbers (P/N) of operability bleed 

valves (OBV) installed. This AD was 

prompted by three failure events of ring 

lock fuel fittings on the OBV. Two of 

those events led to an engine fire. This 

AD requires the affected OBVs be 

removed from service and replaced with 

OBVs eligible for installation. We are 

issuing this AD to prevent failure of 

OBV ring lock fuel fittings, engine fuel 

leakage, uncontrolled fire, and damage 

to the airplane. 

DATES: This AD is effective May 8, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on December 13, 2012 (77 FR 

74125). That NPRM proposed to require 

the affected OBVs be removed from 

service and replaced with OBVs eligible 

for installation. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request To Change ‘‘Operating Hours’’ 

to ‘‘Flight Hours’’ 

American Eagle Airlines requested 

that we change ‘‘operating hours’’ to 

‘‘flight hours’’ throughout the 

document. Airlines track the aircraft 

flight hours, but not the time that an 

engine operates while the aircraft is on 

the ground. 

We agree. We changed the AD to use 

flight hours throughout the AD. 

Request To Change the Compliance 

Time 

General Electric Company requested 

that we simplify the compliance by only 

requiring the OBVs to be replaced 

within two years after the effective date 

of the AD. 

We do not agree. The proposed AD 

compliance is substantiated by risk 

analysis to provide an acceptable level 

of safety during the control program. We 

did not change the AD. 

In Support of the Proposed AD 

The National Transportation Safety 

Board stated that it is in support of the 

proposed AD. 

P/N Corrections 

Since we issued the proposed AD (77 

FR 74125, December 13, 2012), we 

discovered during a technical review 

while preparing to issue the final rule 

AD, that the OBV parts manufacturer 

approval (PMA) P/Ns listed in the 

proposed AD were incorrect. We 

corrected PMA P/Ns 392155–2, 392155– 

3, and 392155–4, to PMA P/Ns 

3291552–2, 3291552–3, and 3291552–4, 

respectively. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

the AD. 

Costs of Compliance 

We estimate that this AD will affect 

300 engines installed on airplanes of 

U.S. registry. We also estimate that it 

will take about two hours per engine to 

perform the actions required by this AD, 

and that the average labor rate is $85 per 

hour. Required parts will cost about 

$25,000 per engine. Based on these 

figures, we estimate the total cost of the 

AD to U.S. operators to be $7,551,000. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(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), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Vicinity of Houston, TX 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule, technical 

amendment. 

SUMMARY: This action amends VHF 

Omnidirectional Range (VOR) Federal 

airways V–68, V–76, V–194, and V–548 

in the vicinity of Houston, TX. The FAA 

is taking this action to correct the 

airway descriptions contained in Part 71 

to ensure they match the information 

contained in the FAA’s aeronautical 

database and depicted on the associated 

aeronautical charts. 

DATES: Effective date April 3, 2013. The 

Director of the Federal Register 

approves this incorporation by reference 

action under 1 CFR part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

History 

In 1999, the geographic coordinates 

reference used to describe the Hobby 

VOR/Distance Measuring Equipment 

(VOR/DME) navigation aid location 

changed and was updated in the FAA 

aeronautical database. However, the 

associated rulemaking action to amend 

the Hobby VOR/DME radial listed in the 

V–68, V–76, V–194, and V–548 

descriptions for describing the airway 

segment between Hobby VOR/DME and 

Industry VOR Tactical Air Navigation 

(VORTAC) (V–68 and V–76), and 

between Hobby VOR/DME and College 

Station VORTAC (V–194 and V–548) 

was not accomplished. As a result, the 

current V–68, V–76, V–194, and V–548 

descriptions do not match the airway 

information contained in the FAA’s 

aeronautical database or the charted 

depiction of the airways on the 

aeronautical charts. The aeronautical 

database and associated charts depict 

the correct Hobby VOR/DME radial for 

V–68, V–76, V–194, and V–548. To 

overcome the conflicting airway 

description information published in 

FAA Order 7400.9W (77 FR 50907, 

August 23, 2012), the FAA is amending 

the V–68, V–76, V–194, and V–548 

descriptions to reflect the correct Hobby 

VOR/DME radial and match the 

information contained in the 

aeronautical database and associated 

charts. 

Accordingly, since this is an 

administrative change to update the 

airway’s description information to 

match the information currently 

contained in the FAA’s aeronautical 

database and published on the 

associated aeronautical charts, notice 

and public procedures under Title 5 

U.S.C. 553(b) are unnecessary. 

The Rule 

The FAA amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending the descriptions of VOR 

Federal airways V–68, V–76, V–194, and 

V–548 in the vicinity of Houston, TX. 

Specifically, the FAA amends V–68 and 

V–76 to reflect the Hobby VOR/DME 

289° radial to define the intersection on 

the airway segment between the Hobby 

VOR/DME and the Industry VORTAC, 

and amends V–194 and V–548 to reflect 

the Hobby VOR/DME 289° radial to 

define the intersection on the airway 

segment between the Hobby VOR/DME 

and the College Station VORTAC. 

Correcting the airway descriptions to 

reflect the correct Hobby VOR/DME 

radial ensures the descriptions match 

the information contained in the FAA’s 

aeronautical database and depicted on 

the associated charts. 

VOR Federal airways are listed in 

paragraph 6010 of FAA Order 7400.9W 

dated August 8, 2012, and effective 

September 15, 2012, which is 

incorporated by reference in 14 CFR 

71.1. The VOR Federal airways listed in 

this document will be revised 

subsequently in the Order. 

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 Department of 

Transportation (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
