AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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 airplane, 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). 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directives 2009–0168, 

dated August 3, 2009; 2009–0116, dated 

May 29, 2009; and 2007–0122, dated 

May 3, 2007 (corrected May 7, 2007) 

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

correct an unsafe condition for the 

specified products. 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 

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.

Federal Register / Vol. 75, No. 45 / Tuesday, March 9, 2010 / Proposed Rules 10697 

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– 

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 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 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.

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 Proposed 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 proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 proposed 

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 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 2 products of U.S. registry. 

We also estimate that it would take 

about 23 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would 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 costs. 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 the 

proposed AD on 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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

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 proposed AD and placed it in the 

AD docket.

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:

(b) None. 

Applicability 

(c) This AD applies to Fokker Services B.V. 

Model F.28 Mark 0070 and Mark 0100 

airplanes, certificated in any category, all 

serial numbers, if an actuator having part 

number (P/N) 9409122 or (P/N) 53–0013 is 

installed on one or both fuel crossfeed valves 

or one or both fuel fire shut-off valves. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28 and 76: Fuel and Engine 

Controls, respectively. 

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 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

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–

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

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. 

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.
