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: 

Due to their position on the aeroplane, fuel 

fire shut-off valve actuators P/N [part 

number] 9409122 are susceptible to freezing, 

which has an adverse effect on the operation 

of the valve. Also, due to various causes, the 

failure rate of [fuel fire shut-off valve] 

actuator P/N 9409122 is higher than 

expected. Failure or freezing of the actuator 

may prevent the flight crew to close the fuel 

fire shut-off valve in case of an engine fire. 

* * * * * 

Due to their position on the aeroplane, fuel 

crossfeed valve actuators P/N 9409122 are 

susceptible to freezing, which has an adverse 

effect on the operation of the valve. This 

condition, if not corrected, may generate fuel 

asymmetry alerts when a valve remains in 

the open position after being selected closed. 

It may also prevent the flight crew from 

correcting a fuel asymmetry when a valve 

remains in the closed position after being 

selected open. One event was reported 

where, due to such problems, the flight crew 

shut down an engine in-flight and diverted 

the aircraft. 

* * * * * 

* * * [D]ue to their position on the aircraft, 

ice may form on actuators P/N 9409122 

installed on fuel crossfeed valves and fuel 

fire shut-off valves. Tests revealed that the 

ice can prevent the actuator and thus the 

valve from operating in flight (frozen stuck). 

* * * 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective July 

28, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 28, 2010.

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 March 9, 2010 (75 FR 

10696). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

In-service experience revealed that, due to 

their position on the aircraft, ice may form 

on actuators P/N 9409122 installed on fuel 

crossfeed valves and fuel fire shut-off valves. 

Tests revealed that the ice can prevent the 

actuator and thus the valve from operating in 

flight (frozen stuck). A new actuator is being 

developed by Fokker Services. However, an 

airworthiness assessment revealed that 

interim actions are required for actuators p/ 

n 9409122 installed on fuel crossfeed valves 

and fuel fire shut-off valves until the new 

actuators are installed. Fokker Services have 

issued Service Bulletin (SB) SBF100–28–049 

to introduce interim actions that will reduce 

the probability that fuel crossfeed and fuel 

fire shut-off valves equipped with actuators 

p/n 9409122 do not operate due to ice. The 

interim actions consist of an operational 

check of the actuators and the application of 

a grease layer on the actuators, followed by 

a weekly visual check of the applied grease 

layer and a 4-weekly operational check of the 

actuators. 

For the reasons stated above, this 

Airworthiness Directive (AD) requires 

compliance with instructions contained in 

the referenced SB. This AD has been republished to correct typographical errors in 

the ‘Remarks’ section, where the word 

‘Proposed’ should have been deleted. 

EASA AD 2009–0116 states: 

Due to their position on the aeroplane, fuel 

crossfeed valve actuators P/N 9409122 are 

susceptible to freezing, which has an adverse 

effect on the operation of the valve. This 

condition, if not corrected, may generate fuel 

asymmetry alerts when a valve remains in 

the open position after being selected closed. 

It may also prevent the flight crew from 

correcting a fuel asymmetry when a valve 

remains in the closed position after being 

selected open. One event was reported 

where, due to such problems, the flight crew 

shut down an engine in-flight and diverted 

the aircraft. 

Aeroplanes with serial numbers 11244 

through 11441 were delivered from the 

production line with actuators P/N 9401037 

(‘‘chimney type’’) installed. However, on 

some aeroplanes, these actuators have 

subsequently been replaced in service with 

actuators P/N 9409122 (using mounting 

blocks P/N 7923505) on one or both fuel 

crossfeed valves. As a result, those 

aeroplanes are also affected by this unsafe 

condition. 

To address and correct this unsafe 

condition, EASA issued AD 2008–0126 that 

required the replacement of all P/N 9409122 

fuel crossfeed valve actuators in accordance 

with Fokker Services SBF100–28–046 with 

new actuators developed by the manufacturer 

Eaton Aerospace, P/N 53–0013, which have 

improved reliability and are less susceptible 

to freezing. 

Following the introduction of actuator P/N 

53–0013 in service, Eaton Aerospace reported 

manufacturing and design errors on actuators 

with P/N 53–0013. As a result of these errors, 

the top-cap of the actuator may become loose, 

possibly leading to actuator failure. Eaton 

Aerospace has eliminated these problems by 

introducing a new actuator P/N 53–0027 and 

Fokker Services have published SBF100–28– 

061 to introduce these improved actuators on 

aeroplanes. 

As the compliance time of EASA AD 2008– 

0126 has not yet expired, both P/N 9409122 

and P/N 53–0013 fuel crossfeed valve 

actuators can currently be installed on 

aeroplanes affected by this AD. 

For the reasons described above, this EASA 

AD retains the requirements of AD 2008– 


jlentini on DSKJ8SOYB1PROD with RULES
35606 Federal Register / Vol. 75, No. 120 / Wednesday, June 23, 2010 / Rules and Regulations 

0126, which is superseded, and adds the 

requirement to install the new P/N 53–0027 

actuators. This AD also allows direct 

installation of P/N 53–0027 on aeroplanes 

that are still in pre-SBF100–28–046 

configuration, provided this is done within 

the compliance time as established for that 

SB in AD 2008–0126 and retained by this 

new AD. 

EASA AD 2009–0168 states: 

Due to their position on the aeroplane, fuel 

fire shut-off valve actuators P/N 9409122 are 

susceptible to freezing, which has an adverse 

effect on the operation of the valve. Also, due 

to various causes, the failure rate of actuator 

P/N 9409122 is higher than expected. Failure 

or freezing of the actuator may prevent the 

flight crew to close the fuel fire shut-off valve 

in case of an engine fire. 

Aeroplanes serial numbers 11244 through 

11441 were delivered from the production 

line with actuators P/N 9401037 (‘‘chimney 

type’’) installed. However, on some 

aeroplanes, these actuators have 

subsequently been replaced in service with 

actuators P/N 9409122 (using mounting 

blocks P/N 7923505) on one or both fuel fire 

shut-off valves. As a result, those aeroplanes 

are also affected by this unsafe condition. 

To address and correct this unsafe 

condition, EASA issued AD 2008–0193, 

requiring the replacement of all P/N 9409122 

fuel fire shut-off valve actuators with new 

actuators developed by the manufacturer 

Eaton Aerospace, P/N 53–0013, which have 

improved reliability and are less susceptible 

to freezing. 

Following the introduction of actuator P/N 

53–0013 in service, Eaton Aerospace reported 

manufacturing and design errors on actuators 

with P/N 53–0013. As a result of these errors, 

the top-cap of the actuator may become loose, 

possibly leading to actuator failure. Eaton 

Aerospace has eliminated these problems by 

introducing a new actuator P/N 53–0027 and 

Fokker Services have published SBF100–76– 

020 to introduce these improved actuators on 

aeroplanes. 

As a consequence of EASA AD 2008–0193, 

both P/N 9409122 and P/N 53–0013 fuel fire 

shut-off valve actuators are currently 

installed on aeroplanes affected by this AD. 

For the reasons described above, this EASA 

AD supersedes AD 2008–0193 and requires 

the installation of new P/N 53–0027 

actuators. This AD also prohibits the 

installation of P/N 53–0013 actuators in 

accordance with SBF100–76–018 (which has 

been cancelled), as previously required by 

EASA AD 2008–0193. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM 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 the AD 

as proposed. 

Differences Between This 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 our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 2 

products of U.S. registry. We also 

estimate that it will take about 23 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $29,800 

per product. Where the service 

information lists required parts costs 

that are covered under warranty, we 

have assumed that there will be no 

charge for these parts. As we do not 

control warranty coverage for affected 

parties, some parties may incur costs 

higher than estimated here. Based on 

these figures, we estimate the cost of 

this AD to the U.S. operators to be 

$63,510, or $31,755 per product. 

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; 

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.

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) consists of 

three EASA ADs: 2007–0122, dated May 3, 

2007 (corrected May 7, 2007); 2009–0116, 

dated May 29, 2009; and MCAI 2009–0168, 

dated August 3, 2009. EASA AD 2007–0122 

states: 

In-service experience revealed that, due to 

their position on the aircraft, ice may form 

on actuators P/N 9409122 installed on fuel 

crossfeed valves and fuel fire shut-off valves. 

Tests revealed that the ice can prevent the 

actuator and thus the valve from operating in 

flight (frozen stuck). A new actuator is being 

developed by Fokker Services. However, an 

airworthiness assessment revealed that 

interim actions are required for actuators p/ 

n 9409122 installed on fuel crossfeed valves 

and fuel fire shut-off valves until the new 

actuators are installed. Fokker Services have 

issued Service Bulletin (SB) SBF100–28–049 

to introduce interim actions that will reduce 

the probability that fuel crossfeed and fuel

p/n 9409122 do not operate due to ice. The 

interim actions consist of an operational 

check of the actuators and the application of 

a grease layer on the actuators, followed by 

a weekly visual check of the applied grease 

layer and a 4-weekly operational check of the 

actuators. 

For the reasons stated above, this 

Airworthiness Directive (AD) requires 

compliance with instructions contained in 

the referenced SB. This AD has been republished to correct typographical errors in 

the ‘Remarks’ section, where the word 

‘Proposed’ should have been deleted. 

EASA AD 2009–0116 states: 

Due to their position on the aeroplane, fuel 

crossfeed valve actuators P/N 9409122 are 

susceptible to freezing, which has an adverse 

effect on the operation of the valve. This 

condition, if not corrected, may generate fuel 

asymmetry alerts when a valve remains in 

the open position after being selected closed. 

It may also prevent the flight crew from 

correcting a fuel asymmetry when a valve 

remains in the closed position after being 

selected open. One event was reported 

where, due to such problems, the flight crew 

shut down an engine in-flight and diverted 

the aircraft. 

Aeroplanes with serial numbers 11244 

through 11441 were delivered from the 

production line with actuators P/N 9401037 

(‘‘chimney type’’) installed. However, on 

some aeroplanes, these actuators have

Aerospace has eliminated these problems by 

introducing a new actuator P/N 53–0027 and 

Fokker Services have published SBF100–28–

As the compliance time of EASA AD 2008– 

0126 has not yet expired, both P/N 9409122 

and P/N 53–0013 fuel crossfeed valve 

actuators can currently be installed on 

aeroplanes affected by this AD. 

For the reasons described above, this EASA

the airplane in accordance with the Master 

Minimum Equipment List (MMEL) Item 28– 

23–1 of MMEL Fokker 70/MMEL Fokker 100, 

paragraph (l) of this AD requires replacing 

affected valves before further flight.

Airworthiness Directives; The Boeing 

Company Model 777–200LR and 

–300ER Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Model 777–200LR and –300ER series 

airplanes. This AD requires doing a high 

frequency eddy current inspection for 

cracking of the keyway of the fuel tank 

access door cutout on the left and right 

wings between wing rib numbers 8 

(wing station 387) and 9 (wing station 

414.5), and related investigative and 

corrective actions if necessary. This AD 

results from reports of cracks emanating 

from the keyway of the fuel tank access 

door cutout of the lower wing skin 

between wing rib numbers 8 and 9. We 

are issuing this AD to prevent loss of the 

lower wing skin load path, which could 

cause catastrophic structural failure of 

the wing. 

DATES: This AD is effective July 28, 

2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 28, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Model 777–200LR and –300ER 

series airplanes. That NPRM was 

published in the Federal Register on 

April 2, 2010 (75 FR 16683). That NPRM 

proposed to require doing a high 

frequency eddy current inspection for
