ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During a recent in-service event the flight 

crew of a Trent 700 powered A330 aircraft 

reported a temporary Engine Pressure Ratio 

(EPR) shortfall on engine 2 during the takeoff phase 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. * * * 

Based on previous industry-wide 

experience, the investigation of the event has 

focused on the possibility for ice to 

temporarily restrict the fuel flow.* * * 

* * * * * 

The scenario of ice being shed and causing 

a temporary blockage in the engine fuel 

system may lead to a temporary fuel flow 

restriction to the engine. This may result in 

a possible engine surge or stall condition, 

and in the engine not being able to provide 

the commanded thrust. 

* * * * * 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective April 

29, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency Airworthiness Directive 

2010–0042–E, dated March 12, 2010 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

During a recent in-service event the flight 

crew of a Trent 700 powered A330 aircraft 

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 previous industry-wide 

experience, the investigation of the event has 

focused on the possibility for ice to 

temporarily restrict the fuel flow. While no 

direct fuel system fault has been identified, 

the operation of the water scavenge system at 

Rib 3 cannot be excluded as being a 

contributory factor. 

Testing and analysis are continuing to 

identify the root cause of the event. 

The scenario of ice being shed and causing 

a temporary blockage in the engine fuel 

system may lead to a temporary fuel flow 

restriction to the engine. This may result in 

a possible engine surge or stall condition, 

and in the engine not being able to provide 

the commanded thrust. 

Therefore, as a precautionary measure to 

reduce the possibility of ingesting ice into the 

engine fuel feed system, this AD requires to: 

—Deactivate the automatic Standby Fuel 

Pump Scavenge System, which operates 

during Taxi and Take-off by removing 

relays Functional Item Numbers (FIN) 

80QA1 and 80QA2 (this will not affect 

normal standby pump operation) for 

aeroplanes identified in the applicability 

section of this AD and on which this 

deactivation has not been performed in 

production through the modification 

200801, and 

—Prohibit the dispatch with * * * [a] MAIN 

Fuel Pump inoperative on all aeroplanes 

identified in the applicability section of 

this AD. 

This AD also requires revising the 

Limitations section of the airplane flight 

manual to advise the flight crew of the 

dispatch prohibition. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued All Operators Telex 

A330–28A3114, Revision 1, dated 

March 24, 2010. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between the AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because ice being shed and causing 

a temporary blockage in the engine fuel 

system could lead to a temporary fuel 

flow restriction to the engine, which 

could result in a possible engine surge 

or stall condition, and in the engine not 

being able to provide the commanded 

thrust. Therefore, we determined that 

notice and opportunity for public 

comment before issuing this AD are 

impracticable and that good cause exists 

for making this amendment effective in 

fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2010–0391; 

Directorate Identifier 2010–NM–073– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

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 this AD: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 


jlentini on DSKJ8SOYB1PROD with RULES
19198 Federal Register / Vol. 75, No. 71 / Wednesday, April 14, 2010 / Rules and Regulations 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2010–08–08 Airbus: Amendment 39– 

16263. Docket No. FAA–2010–0391; 

Directorate Identifier 2010–NM–073–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 29, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A330– 

243, –341, –342, and –343 airplanes, 

certificated in any category, all manufacturer 

serial numbers equipped with Rolls-Royce 

Trent 700 engines, on which Airbus 

modification 56966MP16199 has been 

embodied in production or Airbus Service 

Bulletin A330–28–3105 has been embodied 

in service. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continued airworthiness 

information (MCAI) states: 

During a recent in-service event the flight 

crew of a Trent 700 powered A330 aircraft 

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 previous industry-wide 

experience, the investigation of the event has 

focused on the possibility for ice to 

temporarily restrict the fuel flow. While no 

direct fuel system fault has been identified, 

the operation of the water scavenge system at 

Rib 3 cannot be excluded as being a 

contributory factor. 

Testing and analysis are continuing to 

identify the root cause of the event. 

The scenario of ice being shed and causing 

a temporary blockage in the engine fuel 

system may lead to a temporary fuel flow 

restriction to the engine. This may result in 

a possible engine surge or stall condition, 

and in the engine not being able to provide 

the commanded thrust. 

Therefore, as a precautionary measure to 

reduce the possibility of ingesting ice into the 

engine fuel feed system, this AD requires to: 

—Deactivate the automatic Standby Fuel 

Pump Scavenge System, which operates 

during Taxi and Take-off by removing 

relays Functional Item Numbers (FIN) 

80QA1 and 80QA2 (this will not affect 

normal standby pump operation) for 

aeroplanes identified in the applicability 

section of this AD and on which this 

deactivation has not been performed in 

production through the modification 

200801, and 

—Prohibit the dispatch with * * * [a] MAIN 

Fuel Pump inoperative on all aeroplanes 

identified in the applicability section of 

this AD. 

This AD also requires revising the 

Limitations section of the airplane flight 

manual to advise the flight crew of the 

dispatch prohibition. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) For airplanes on which Airbus 

modification 200801 has not been embodied 

in production as of the effective date of this 

AD: Within 10 days after the effective date 

of this AD, deactivate the water scavenge 

automatic operation by removing relays FIN 

80QA1 (left-hand) and 80QA2 (right-hand), 

in accordance with the instructions in Airbus 

All Operators Telex A330–28A3114, Revision 

1, dated March 24, 2010. 

(h) Deactivation before the effective date of 

this AD in accordance with Airbus All 

Operators Telex A330–28A3114, dated 

March 10, 2010, is considered acceptable for 

compliance with the corresponding action 

required by paragraph (g) of this AD. 

(i) For airplanes on which Airbus 

modification 200801 has not been embodied 

in production as of the effective date of this 

AD: Before further flight after 

accomplishment of the requirements of 

paragraph (g) of this AD, dispatch of an

(k) For all airplanes: At the applicable time 

specified in paragraph (k)(1) or (k)(2) of this 

AD, revise the Limitations section of the 

airplane flight manual (AFM) to include the 

following statement. This may be done by 

inserting a copy of this AD into the AFM. 

‘‘Dispatch with any inoperative main fuel 

pump is prohibited.’’ 

(1) For airplanes on which Airbus

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

It was noticed in production that in the 

area between frame (FR) C53.9 and FR C55 

RH [right-hand], the distance between the 

route 9R of the In-Flight Entertainment 

system and the wire harness for the Lower 

Deck-Mobile Crew Rest system provisions is 

too small. 

This limited distance may cause chafing 

between the affected electrical harness 

6581VB and the harness 5495VB or 6938VB. 

This condition, if not corrected, could lead 

to the short circuit of wires dedicated to 

oxygen, which, in case of emergency, could 

result in a large number of passenger oxygen 

masks not being supplied with oxygen,

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 was published in the Federal 

Register on December 1, 2009 (74 FR 

62711). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

It was noticed in production that in the 

area between frame (FR) C53.9 and FR C55 

RH [right-hand], the distance between the 

route 9R of the In-Flight Entertainment 

system and the wire harness for the Lower 

Deck-Mobile Crew Rest system provisions is 

too small. 

This limited distance may cause chafing 

between the affected electrical harness 

6581VB and the harness 5495VB or 6938VB. 

This condition, if not corrected, could lead 

to the short circuit of wires dedicated to 

oxygen, which, in case of emergency, could 

result in a large number of passenger oxygen 

masks not being supplied with oxygen, 

possibly causing personal injuries. 

For the reasons described above, this AD 

requires the installation of a stirrup on the 

terminal block 5507VT between FR53.9 and 

FR54, and the re-routing of the wiring route 

9R. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to
