Federal Register / Vol. 76, No. 53 / Friday, March 18, 2011 / Rules and Regulations 14799 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–06–11 Rolls-Royce plc (RR): 

Amendment 39–16636; Docket No. 

FAA–2011–0176; Directorate Identifier 

2011–NE–05–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 4, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to RR model RB211– 

Trent 970–84, 970B–84, 972–84, 972B–84, 

977–84, 977B–84, and 980–84 turbofan 

engines. These engines are installed on, but 

not limited to, Airbus A380 series airplanes. 

Reason 

(d) An uncontained engine failure has 

recently occurred on a Rolls-Royce RB211 

Trent 900 involving release of high energy 

debris and resulting in damage to the 

aeroplane. Analysis of the available elements 

from the incident investigation shows that an 

oil fire in the High Pressure/Intermediate 

Pressure (HP/IP) structure cavity may have 

initiated a sequence of events leading to 

rupture of the drive arm of the IP Turbine 

(IPT) disc and subsequent overspeed and 

burst of that same disc. 

Rolls-Royce has developed a modification 

of the Engine Electronic Controller (EEC) 

software, featuring an IPT Overspeed 

Protection System (IPTOS). The purpose of 

the IPTOS functionality is to detect engine 

conditions that may potentially lead to an IP 

turbine overspeed, and shut down the engine 

before the level of overspeed reaches the disc 

burst speed. 

We are issuing this AD to prevent overspeed 

of the intermediate pressure turbine, which 

could result in loss of disc integrity, an 

uncontained failure of the engine, and 

damage to the airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions: 

(1) Within 10 flight cycles after the 

effective date of this AD, incorporate 

software 10.6 to the EEC. 

(2) Guidance on incorporating software 

10.6 can be found in Rolls-Royce plc Trent 

900 Series Propulsion Systems Alert Service 

Bulletin (SB) No. RB.211–73–AG639, dated 

December 3, 2010. 

Prior Software Version Prohibition 

(3) After incorporation of software 10.6, do 

not incorporate any software version prior to 

10.6 to the EEC. 

FAA AD Differences 

(f) This AD differs from the Mandatory 

Continuing Airworthiness Information 

(MCAI) as follows: 

(1) MCAI European Aviation Safety Agency 

(EASA) AD 2010–0262, dated December 13, 

2010, requires that after EEC modification of 

an installed engine as required by that AD, 

do not intermix with any EEC software 

standards prior to modification 73–F328 

(standard 9.2.1) on that airplane. This AD 

does not, because there are no U.S. registered 

airplanes with RB211–Trent 900 engines. 

(2) MCAI EASA AD 2010–0262, dated 

December 13, 2010, states that from the 

effective date of the AD, no engine may be 

installed in an airplane unless the engine has 

incorporated the new software. This AD does 

not, because there are no U.S. registered 

airplanes with RB211–Trent 900 engines. 

(3) MCAI EASA AD 2010–0262, dated 

December 13, 2010, allows incorporation of 

later approved versions of EEC software 

standards that will include IPTOS 

functionality. This AD does not. Instead, we 

prohibit software installation prior to version 

10.6. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

(h) Refer to MCAI EASA AD 2010–0262, 

dated December 13, 2010, and Rolls-Royce

Docket No. 10–ANE–108] 

Amendment of Class E Airspace; 

Newport, VT 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class E 

airspace at Newport, Vermont. The 

Newport Non-Directional Beacon (NDB) 

has been decommissioned and new 

Standard Instrument Approach 

Procedures (SIAPs) have been 

developed for Newport State Airport. 

This action enhances the safety and 

airspace management of Instrument 

Flight Rules (IFR) operations at the 

airport. 

DATES: Effective date: 0901 UTC, June 

30, 2011. The Director of the Federal 

Register approves this incorporation by 

reference action under title 1, Code of 

Federal Regulations, part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

History 

On November 29, 2010, the FAA 

published in the Federal Register a 

notice of proposed rulemaking to amend 

Class E airspace 700 feet above the 

surface, at Newport, VT (75 FR 73015) 

Docket No. FAA–2010–0938. 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 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in the Order. 

The Rule 

This amendment to Title 14, Code of 

Federal Regulations (14 CFR) part 71 

amends Class E airspace extending 

upward from 700 feet above the surface 

to support new SIAPs developed at 

Newport State Airport, Newport, 

Vermont. Airspace reconfiguration is 

necessary due to the decommissioning 

of the Newport NDB and cancellation of 

the NDB approach. Controlled airspace 

is necessary for the safety and 

management of IFR operations at the 

airport. 

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, is non-controversial and 

unlikely to result in adverse or negative 

comments. It, therefore, (1) Is not a 

‘‘significant regulatory action’’ under 

WReier-Aviles on DSKGBLS3C1PROD with RULES

14800 Federal Register / Vol. 76, No. 53 / Friday, March 18, 2011 / Rules and Regulations 

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 United States Code. 

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. 

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 Class E airspace at Newport, 

Vermont.

SUPPLEMENTARY INFORMATION: 

History 

On December 28, 2010, the FAA 

published in the Federal Register a 

Notice of Proposed Rulemaking to 

establish Class E airspace at Wolfeboro, 

NH (75 FR 81518). 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 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in the Order. 

The Rule 

This amendment to Title 14, Code of 

Federal Regulations (14 CFR) part 71 

establishes the Class E airspace 

extending upward from 700 feet above 

the surface at Wolfeboro, NH, to provide 

controlled airspace required to support 

the RNAV (GPS) special standard 

instrument approach procedures 

developed for Huggins Hospital 

Heliport. This action is necessary for the 

safety and management of IFR 

operations at the heliport. 

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
