AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; removal. 

SUMMARY: We are removing 

Airworthiness Directive (AD) 2010–08– 

08, which applied to certain Airbus 

Model A330–243, –341, –342, and –343 

airplanes. AD 2010–08–08 required 

deactivating the water scavenge 

automatic operation and revising the 

Limitations section of the airplane flight 

manual (AFM). We are also removing 

AD 2011–06–04, which applied to 

certain Airbus Model A330–243F 

airplanes. AD 2011–06–04 required 

revising the Limitations section of the 

AFM. We issued ADs 2010–08–08 and 

2011–06–04 to prevent fuel flow 

restriction, caused by ice, resulting in a 

possible engine surge or stall condition, 

and the engine being unable to provide 

the commanded thrust. Since we issued 

AD 2010–08–08 and AD 2011–06–04, 

we received new data indicating that the 

water scavenge system (WSS) operation 

does not induce any risk of fuel feed 

system (including the engine) blockage 

by ice on the pipework or pump inlets. 

We have also determined that the risk 

of fuel flow restriction by ice at the fuel 

oil heat exchanger (FOHE) interface on 

airplanes equipped with Rolls-Royce 

Trent 700 engines is now addressed by 

a redesigned FOHE, which incorporates 

enhanced anti-icing and de-icing 

performance. 

DATES: This AD becomes effective 

November 23, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus Model A330– 

243, –243F, –341, –342, and –343 

airplanes. The NPRM published in the 

Federal Register on October 2, 2014 (79 

FR 59468). The NPRM proposed to 

remove AD 2010–08–08, Amendment 

39–16263 (75 FR 19196, April 14, 2010), 

and AD 2011–06–04, Amendment 39– 

16628 (76 FR 13075, March 10, 2011). 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2010– 

0132–CN, dated October 14, 2013 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to cancel EASA AD 

2010–0132R1, dated June 10, 2013, 

which superseded EASA AD 2010– 

0132, dated June 28, 2010. The 

requirements of FAA AD 2010–08–08, 

Amendment 39–16263 (75 FR 19196, 

April 14, 2010), and AD 2011–06–04, 

Amendment 39–16628 (76 FR 13075, 

March 10, 2011), correspond to EASA 

AD 2010–0132. The MCAI states: 

During an in-service event, the flight crew 

of a Trent 700 powered A330 aeroplane 

reported a temporary Engine Pressure Ratio 

(EPR) shortfall on engine 2 during the takeoff 

phase of the flight. The ENG STALL warning 

was set. The flight crew followed the 

standard procedures which included 

reducing throttle to idle. The engine 

recovered and provided the demanded thrust 

level for the remainder of the flight. 

Data analysis confirmed a temporary fuel 

flow restriction and subsequent recovery, and 

indicated that also engine 1 experienced a 

temporary fuel flow restriction shortly after 

the initial event on engine 2, again followed 

by a full recovery. The engine 1 EPR shortfall 

was insufficient to trigger any associated 

warning and was only noted through analysis 

of the flight data. No flight crew action was 

necessary to recover normal performance on 

this engine. The remainder of the flight was 

uneventful. 

Based on industry-wide experience, the 

investigation of the event focused on the 

possibility for ice to temporarily restrict the 

fuel flow. While no direct fuel system fault 

was identified, the operation of the water 

scavenge system (WSS) at Rib 3 was 

considered to have been a contributory 

factor. 

Prompted by these findings, EASA issued 

[EASA] Emergency AD 2010–0042–E [http:// 

ad.easa.europa.eu/ad/2010-0042-E] [which 

corresponds to FAA AD 2010–08–08, 

Amendment 39–16263 (75 FR 19196, April 

14, 2010] to require deactivation of the 

automatic Standby Fuel Pump Scavenge 

System and to prohibit dispatch of an 

aeroplane with one main fuel pump 

inoperative. 

Subsequently, EASA issued [EASA] AD 

2010–0132 which superseded EASA AD 

2010–0042–E, retaining its requirements, to 

expand the applicability to the newly 

certified model A330–243F [which 

corresponds to FAA AD 2011–06–04, 

Amendment 39–16628 (76 FR 13075, March 

10, 2011, for the A330–243F requirements]. 

EASA AD 2010–0132 was later revised to 

remove the dispatch restriction with one 

main fuel pump inoperative. 

Since EASA AD 2010–0132R1 was issued, 

extensive fuel system icing risk 

investigations testing was conducted by 

Airbus and Rolls-Royce, the results of which 

confirmed that the Rib 3 WSS operation does 

not induce any risk of fuel feed system 

(including the engine) blockage by ice 

accreted on the pipework and/or pump 

inlets. In addition, it was demonstrated that 

the risk of fuel flow restriction by ice at the 

Fuel Oil Heat Exchanger (FOHE) interface on 

aeroplanes equipped with Trent 700 engines 

is now adequately addressed by introduction 

of a re-designed FOHE, more tolerant to the 

release of ice (modification 200218). The 


asabaliauskas on DSK5VPTVN1PROD with FRONTMATTER
63080 Federal Register / Vol. 80, No. 201 / Monday, October 19, 2015 / Rules and Regulations 

modified FOHE (incorporating enhanced 

anti-icing and de-icing performance) is 

required to be installed on all Trent 700 

engines through EASA AD 2009–0257 

[http://ad.easa.europa.eu/ad/2009-0257] 

[which corresponds to FAA AD 2010–07–01, 

Amendment 39–16244 (75 FR 15326, March 

29, 2010)]. 

Previously, the operation of the WSS at Rib 

3 was no longer considered as a main 

contributory factor on ice build-up and 

subsequent release of ice into the fuel system. 

Based on the latest information, the 

deactivation of the automatic Standby Fuel 

Pump Scavenge System is no longer required. 

For the reasons described above, this 

Notice cancels EASA AD 2010–0132R1.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 59468, October 2, 2014), or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

59468, October 2, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 59468, 

October 2, 2014). 

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 

We determined that 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 the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska; 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.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A330–200, A330–200 

Freighter, A330–300, A340–200, A340– 

300, A340–500, and A340–600 series 

airplanes. This AD requires a detailed 

inspection of the girt installation of each 

escape slide and slide raft, and 

corrective action if necessary. This AD 

was prompted by a report of incorrect 

installation of the girt panel on 

passenger doors and an incorrectly 

installed quick release (girt) bar into the 


asabaliauskas on DSK5VPTVN1PROD with FRONTMATTER
