Model F.28 Mark 0070 and 0100 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: 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: SUMMARY: When preparing for landing, the flight crew of a F28 Mark 0100 (Fokker 100) aeroplane observed a main landing gear (MLG) unsafe indication after landing gear down selection. * * * [T]he right (RH) MLG was partly extended and the left (LH) MLG door was open but without the MLG being extended. * * * Subsequent investigation revealed that the cause of the MLG extension problem was the (partially) blocked hydraulic return line from the MLG selector valve by pieces of hard plastic.

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 May 18, 2010 (75 FR 27668). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: When preparing for landing, the flight crew of a F28 Mark 0100 (Fokker 100) aeroplane observed a main landing gear (MLG) unsafe indication after landing gear down selection. The approach was aborted and the landing gear unsafe procedure was accomplished. As this did not produce the desired effect, a low pass was performed and the control tower confirmed that the right (RH) MLG was partly extended and the left (LH) MLG door was open but without the MLG being extended. Eventually the aeroplane landed with partly extended landing gear, without resulting in serious injuries to the occupants. Subsequent investigation revealed that the cause of the MLG extension problem was the (partially) blocked hydraulic return line from the MLG selector valve by pieces of hard plastic. These were identified as parts of the poppet seat of PBSOV [parking brake shut-off valve] Part Number (P/N) 70379. The PBSOV installed on the incident aeroplane was a modified version of P/N 70379, identified by suffix ‘‘A’’ behind the serial number on the identification plate. This modification was introduced by Eaton, the valve manufacturer, with Eaton Service Bulletin (SB) 70379–32– 01 and includes replacement of the original poppet with clamped hard plastic seat by an improved poppet assembly with screwed-on seat. When the affected valve was opened, it was confirmed that it contained the improved poppet assembly. The poppet seat fragments found in the return system therefore originated from a previously installed (pre SB 70379–32–01) P/N 70379 PBSOV and must have been present in the return/pressure line prior to installation of the modified PBSOV. This condition, if not detected and corrected, could lead to further events where the MLG fails to extend, possibly resulting in loss of control of the aeroplane during landing. For the reasons described above, this [EASA] AD requires the [detailed] inspection of the associated hydraulic lines, irrespective what type PBSOV is installed, removal of E:\FR\FM\29OCR1.SGM 29OCR1 66650 Federal Register / Vol. 75, No. 209 / Friday, October 29, 2010 / Rules and Regulations contamination in the system, if any, and replacement of each unmodified PBSOV with a modified unit. This [EASA] AD also prohibits, after installation of a modified PBSOV on an aeroplane, re-installation of an unmodified PBSOV on that aeroplane. 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 6 products of U.S. registry. We also estimate that it will take about 4 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $2,040, or $340 per product. WReier-Aviles on DSKGBLS3C1PROD with RULES 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 VerDate Mar<15>2010 13:56 Oct 28, 2010 Jkt 223001 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. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

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

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

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:

    When preparing for landing, the flight crew of a F28 Mark 0100 
(Fokker 100) aeroplane observed a main landing gear (MLG) unsafe 
indication after landing gear down selection. * * * [T]he right (RH) 
MLG was partly extended and the left (LH) MLG door was open but 
without the MLG being extended. * * *
    Subsequent investigation revealed that the cause of the MLG 
extension problem was the (partially) blocked hydraulic return line 
from the MLG selector valve by pieces of hard plastic. These were 
identified as parts of the poppet seat of PBSOV [parking brake shut-
off valve] Part Number (P/N) 70379. * * *
    This condition, if not detected and corrected, could lead to 
further events where the MLG fails to extend, possibly resulting in 
loss of control of the aeroplane during landing.
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 3, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 3, 
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 May 18, 2010 (75 FR 
27668). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    When preparing for landing, the flight crew of a F28 Mark 0100 
(Fokker 100) aeroplane observed a main landing gear (MLG) unsafe 
indication after landing gear down selection. The approach was 
aborted and the landing gear unsafe procedure was accomplished. As 
this did not produce the desired effect, a low pass was performed 
and the control tower confirmed that the right (RH) MLG was partly 
extended and the left (LH) MLG door was open but without the MLG 
being extended. Eventually the aeroplane landed with partly extended 
landing gear, without resulting in serious injuries to the 
occupants.
    Subsequent investigation revealed that the cause of the MLG 
extension problem was the (partially) blocked hydraulic return line 
from the MLG selector valve by pieces of hard plastic. These were 
identified as parts of the poppet seat of PBSOV [parking brake shut-
off valve] Part Number (P/N) 70379. The PBSOV installed on the 
incident aeroplane was a modified version of P/N 70379, identified 
by suffix ``A'' behind the serial number on the identification 
plate. This modification was introduced by Eaton, the valve 
manufacturer, with Eaton Service Bulletin (SB) 70379-32-01 and 
includes replacement of the original poppet with clamped hard 
plastic seat by an improved poppet assembly with screwed-on seat. 
When the affected valve was opened, it was confirmed that it 
contained the improved poppet assembly. The poppet seat fragments 
found in the return system therefore originated from a previously 
installed (pre SB 70379-32-01) P/N 70379 PBSOV and must have been 
present in the return/pressure line prior to installation of the 
modified PBSOV.
    This condition, if not detected and corrected, could lead to 
further events where the MLG fails to extend, possibly resulting in 
loss of control of the aeroplane during landing.
    For the reasons described above, this [EASA] AD requires the 
[detailed] inspection of the associated hydraulic lines, 
irrespective what type PBSOV is installed, removal of

[[Page 66650]]

contamination in the system, if any, and replacement of each 
unmodified PBSOV with a modified unit. This [EASA] AD also 
prohibits, after installation of a modified PBSOV on an aeroplane, 
re-installation of an unmodified PBSOV on that aeroplane.

    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 6 products of U.S. registry. 
We also estimate that it will take about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $2,040, or $340 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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2010-22-05 Fokker Services B.V.: Amendment 39-16484. Docket No. FAA-
2010-0516; Directorate Identifier 2009-NM-251-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
3, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Fokker Services B.V. Model F.28 Mark 0070 
and 0100 airplanes, certificated in any category, all serial 
numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 32: Landing 
Gear.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    When preparing for landing, the flight crew of a F28 Mark 0100 
(Fokker 100) aeroplane observed a main landing gear (MLG) unsafe 
indication after landing gear down selection. * * * [T]he right (RH) 
MLG was partly extended and the left (LH) MLG door was open but 
without the MLG being extended. * * *
    Subsequent investigation revealed that the cause of the MLG 
extension problem was the (partially) blocked hydraulic return line 
from the MLG selector valve by pieces of hard plastic. These were 
identified as parts of the poppet seat of PBSOV [parking brake shut-
off valve] Part Number (P/N) 70379. * * *
    This condition, if not detected and corrected, could lead to 
further events where the MLG fails to extend, possibly resulting in 
loss of control of the aeroplane during landing.
* * * * *

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) Do the following actions.
    (1) Within 30 days after the effective date of this AD, do a 
detailed inspection of the hydraulic lines associated with the PBSOV 
for contamination in the system (the presence of pieces of material 
from the poppet seat of an unmodified PBSOV having P/N 70379). If 
any contamination is found, before further flight, remove the 
contamination, in accordance with Part 1 of the Accomplishment 
Instructions of Fokker Service Bulletin SBF100-32-159, dated October 
6, 2009.
    (2) Within 18 months after the effective date of this AD, re-
inspect the hydraulic lines and do all applicable corrective actions 
as required by paragraph (g)(1) of this AD, and replace the 
unmodified PBSOV having P/N 70379, with a modified PBSOV having P/N

[[Page 66651]]

70379 having the suffix ``A'' behind the serial number on the 
identification plate, in accordance with Part 2 of the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-32-
159, dated October 6, 2009.
    (3) After accomplishing paragraph (g)(2) of this AD, do not 
install any unmodified PBSOV having P/N 70379, unless the PBSOV 
having P/N 70379 has been modified, having the suffix ``A'' behind 
the serial number on the identification plate, in accordance with 
the Accomplishment Instructions of Eaton Service Bulletin 70379-32-
01, dated September 15, 2001.
