Airworthiness Directives; Fokker Services B.V. Model F.28 Mark 
0070 and 0100 Airplanes

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.

DATES: We must receive comments on this proposed AD by April 23, 2010.

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.

[[Page 10697]]

    For the reasons stated above, this Airworthiness Directive (AD) 
requires compliance with instructions contained in the referenced 
SB. This AD has been re-published 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Fokker Services B.V.: Docket No. FAA-2010-0220; Directorate 
Identifier 2008-NM-166-AD.

Comments Due Date

    (a) We must receive comments by April 23, 2010.

Affected ADs

    (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

[[Page 10699]]

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 re-published 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 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

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
