Download as PDF Federal Register / Vol. 74, No. 215 / Monday, November 9, 2009 / Rules and Regulations and ball nut could potentially lead to a flap system jam. A Temporary Revision (TR) has been made to the Bombardier CL–600–2B19 Maintenance Requirements Manual (MRM), Appendix A, ‘‘Certification Maintenance Requirements’’ (CMR) to ensure that unacceptable wear on the nut and ball screw is detected and corrected. Revision 1 of this directive introduces a new phase-in schedule for performing a new CMR task C27–50–300–01. The unsafe condition is a flap system jam, which could result in a skewed flap condition with consequent reduced controllability of the airplane. Actions and Compliance (f) Unless already done, within 30 days after the effective date of this AD, revise the Airworthiness Requirements Section of the Bombardier CL–600–2B19 MRM to include the information in Bombardier TR 2A–41, dated November 7, 2007, to Appendix A of the Airworthiness Requirements, Part 2, of the Bombardier CL–600–2B19 MRM. The initial compliance with the new CMR task must be done within 500 flight hours after the effective date of this AD. Note 2: The actions required by paragraph (f) of this AD may be done by inserting a copy of Bombardier TR 2A–41, dated November 7, 2007, to Appendix A of the Airworthiness Requirements, Part 2, of the Bombardier CL–600–2B19 MRM. When this TR has been included in general revisions of the MRM, the TR may be removed from the MRM, provided the relevant information in the general revision is identical to that in Bombardier TR 2A–41, dated November 7, 2007.

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) issued 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: Some cases of uncommanded steering action were observed, while the steering system was switched off. A leakage in the Steering Select/Bypass Valve, installed in the Steering Manifold, when closed, is suspected to have caused the uncommanded steering. If left uncorrected, this condition could lead to a potentially dangerous veer along the runway; in fact, according to the Aircraft Flight Manual limitations, the steering system must be in ‘off’ position during landing and takeoff (in this case when airspeed is higher than 60 knots). We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective December 14, 2009. On December 14, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590. FOR FURTHER INFORMATION CONTACT: Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329– 4145; fax: (816) 329–4090. SUPPLEMENTARY INFORMATION: E:\FR\FM\09NOR1.SGM 09NOR1 57562 Federal Register / Vol. 74, No. 215 / Monday, November 9, 2009 / Rules and Regulations 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 August 5, 2009 (74 FR 38991). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Some cases of uncommanded steering action were observed, while the steering system was switched off. A leakage in the Steering Select/Bypass Valve, installed in the Steering Manifold, when closed, is suspected to have caused the uncommanded steering. If left uncorrected, this condition could lead to a potentially dangerous veer along the runway; in fact, according to the Aircraft Flight Manual limitations, the steering system must be in ‘off’ position during landing and takeoff (in this case when airspeed is higher than 60 knots). For the reasons stated above, this new AD mandates repetitive inspections for leakage of the Nose Landing Gear steering manifold. The MCAI requires, if any inspection finds leakage of the steering manifold, the replacement of the steering manifold. WReier-Aviles on DSKGBLS3C1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Mr. Carlo Cardu, Piaggio Aero Industries, states that revisions of airplane maintenance manuals (AMM) will be issued. He suggests that the final AD action include a statement that later revisions of AMM is acceptable for compliance with the requirements of the AD. The FAA does not agree with including the phrase ‘‘or later revision’’ after the referenced service information. The FAA cannot approve and legally reference documents that currently do not exist. When these documents are completed and approved, the FAA can issue an alternative method of compliance if the FAA determines that the incorporation of the procedures provides an acceptable level of safety to the unsafe condition specified in the AD. We are not changing the final rule AD action as a result of this comment. Conclusion We reviewed the available data, including the comment received, 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 VerDate Nov<24>2008 15:01 Nov 06, 2009 Jkt 220001 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. Costs of Compliance We estimate that this AD will affect 63 products of U.S. registry. We also estimate that it will take about 8 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $40,320 or $640 per product. In addition, we estimate that any necessary follow-on actions will take about 16 work-hours and require parts costing $0, for a cost of $1,280 per product. We have no way of determining the number of products that may need these actions. 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. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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 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 http:// www.regulations.gov; or in person at the Docket Management Facility 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 Office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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: ■ 2009–21–08 PIAGGIO AERO INDUSTRIES S.p.A.: Amendment 39–16047; Docket No. FAA–2009–0699; Directorate Identifier 2009–CE–042–AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 14, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Model P–180 airplanes, all serial numbers (S/N), certificated in any category. E:\FR\FM\09NOR1.SGM 09NOR1 Federal Register / Vol. 74, No. 215 / Monday, November 9, 2009 / Rules and Regulations Subject (d) Air Transport Association of America (ATA) Code 32: Landing Gear. Reason (e) The mandatory continuing airworthiness information (MCAI) states: Some cases of uncommanded steering action were observed, while the steering system was switched off. A leakage in the Steering Select/Bypass Valve, installed in the Steering Manifold, when closed, is suspected to have caused the uncommanded steering. If left uncorrected, this condition could lead to a potentially dangerous veer along the runway; in fact, according to the Aircraft Flight Manual limitations, the steering system must be in ‘‘off’’ position during landing and takeoff (in this case when airspeed is higher than 60 knots). For the reasons stated above, this new AD mandates repetitive inspections for leakage of the Nose Landing Gear steering manifold. The MCAI requires, if any inspection finds leakage of the steering manifold, the replacement of the steering manifold. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 6 months after December 14, 2009 (the effective date of this AD) or within the next 100 hours time-inservice (TIS) after December 14, 2009 (the effective date of this AD), whichever occurs first, and repetitively thereafter at intervals not to exceed every 165 hours TIS, do a functional test of the nose landing gear (NLG) steering manifold. Follow the accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N. 80–0249 (includes CONFIRMATION SLIP), Rev. 1, dated May 27, 2009.

ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 737– 300, –400, and –500 series airplanes. The existing AD currently requires inspecting to determine if certain carriage spindles are installed, repetitive inspections for corrosion and indications of corrosion on affected carriage spindles, and if necessary, related investigative and corrective actions. The existing AD also provides optional terminating action. For certain airplanes, this new AD would reinstate the requirements of the existing AD. This AD results from the exclusion of VerDate Nov<24>2008 15:01 Nov 06, 2009 Jkt 220001 certain carriage spindles from the requirements of the existing AD, and additional reports of corrosion found on carriage spindles that are located on the outboard trailing edge flaps. We are issuing this AD to detect and correct corrosion of the carriage spindle, which could result in fracture. Fracture of both the inboard and outboard carriage spindles, in the forward ends through the large diameters, on a flap, could adversely affect the airplane’s continued safe flight and landing. DATES: This AD becomes effective November 24, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 24, 2009. On August 5, 2008 (73 FR 42259, July 21, 2008), the Director of the Federal Register approved the incorporation by reference of a certain other publication listed in the AD. We must receive any comments on this AD by December 24, 2009. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

14 CFR Part 39

[Docket No. FAA-2009-0699 Directorate Identifier 2009-CE-042-AD; 
Amendment 39-16047; AD 2009-21-08]

Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model 
PIAGGIO P-180 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) issued 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:

    Some cases of uncommanded steering action were observed, while 
the steering system was switched off. A leakage in the Steering 
Select/Bypass Valve, installed in the Steering Manifold, when 
closed, is suspected to have caused the uncommanded steering.
    If left uncorrected, this condition could lead to a potentially 
dangerous veer along the runway; in fact, according to the Aircraft 
Flight Manual limitations, the steering system must be in `off' 
position during landing and takeoff (in this case when airspeed is 
higher than 60 knots).

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 14, 2009.
    On December 14, 2009, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at Document Management Facility, U.S.

SUPPLEMENTARY INFORMATION:

[[Page 57562]]

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 August 5, 2009 (74 
FR 38991). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Some cases of uncommanded steering action were observed, while 
the steering system was switched off. A leakage in the Steering 
Select/Bypass Valve, installed in the Steering Manifold, when 
closed, is suspected to have caused the uncommanded steering.
    If left uncorrected, this condition could lead to a potentially 
dangerous veer along the runway; in fact, according to the Aircraft 
Flight Manual limitations, the steering system must be in `off' 
position during landing and takeoff (in this case when airspeed is 
higher than 60 knots). For the reasons stated above, this new AD 
mandates repetitive inspections for leakage of the Nose Landing Gear 
steering manifold.

The MCAI requires, if any inspection finds leakage of the steering 
manifold, the replacement of the steering manifold.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.
    Mr. Carlo Cardu, Piaggio Aero Industries, states that revisions of 
airplane maintenance manuals (AMM) will be issued. He suggests that the 
final AD action include a statement that later revisions of AMM is 
acceptable for compliance with the requirements of the AD.
    The FAA does not agree with including the phrase ``or later 
revision'' after the referenced service information. The FAA cannot 
approve and legally reference documents that currently do not exist. 
When these documents are completed and approved, the FAA can issue an 
alternative method of compliance if the FAA determines that the 
incorporation of the procedures provides an acceptable level of safety 
to the unsafe condition specified in the AD.
    We are not changing the final rule AD action as a result of this 
comment.

Conclusion

    We reviewed the available data, including the comment received, 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 FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 63 products of U.S. registry. 
We also estimate that it will take about 8 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $80 per work-hour.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $40,320 or $640 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 16 work-hours and require parts costing $0, for a cost of 
$1,280 per product. We have no way of determining the number of 
products that may need these actions.

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 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 http://www.regulations.gov; or in person at the Docket Management Facility 
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 Office (telephone (800) 647-5527) is in the ADDRESSES 
section. Comments will be available in the AD docket shortly after 
receipt.

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

2009-21-08 PIAGGIO AERO INDUSTRIES S.p.A.: Amendment 39-16047; 
Docket No. FAA-2009-0699; Directorate Identifier 2009-CE-042-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
14, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model P-180 airplanes, all serial numbers 
(S/N), certificated in any category.

[[Page 57563]]

Subject

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

Reason

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

    Some cases of uncommanded steering action were observed, while 
the steering system was switched off. A leakage in the Steering 
Select/Bypass Valve, installed in the Steering Manifold, when 
closed, is suspected to have caused the uncommanded steering.
    If left uncorrected, this condition could lead to a potentially 
dangerous veer along the runway; in fact, according to the Aircraft 
Flight Manual limitations, the steering system must be in ``off'' 
position during landing and takeoff (in this case when airspeed is 
higher than 60 knots). For the reasons stated above, this new AD 
mandates repetitive inspections for leakage of the Nose Landing Gear 
steering manifold.

The MCAI requires, if any inspection finds leakage of the steering 
manifold, the replacement of the steering manifold.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 6 months after December 14, 2009 (the 
effective date of this AD) or within the next 100 hours time-in-
service (TIS) after December 14, 2009 (the effective date of this 
AD), whichever occurs first, and repetitively thereafter at 
intervals not to exceed every 165 hours TIS, do a functional test of 
the nose landing gear (NLG) steering manifold. Follow the 
accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. 
Service Bulletin (Mandatory) N. 80-0249 (includes CONFIRMATION 
SLIP), Rev. 1, dated May 27, 2009.
    (2) Upon installation of a NLG steering manifold on any 
airplane, do a functional test of the NLG steering manifold. 
Repetitively thereafter at intervals not to exceed every 165 hours 
TIS, do a functional test of the NLG steering manifold. Follow the 
accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. 
Service Bulletin (Mandatory) N. 80-0249 (includes CONFIRMATION 
SLIP), Rev. 1, dated May 27, 2009.
    (3) If during any inspection required in paragraphs (f)(1) and 
(f)(2) of this AD movement of a NLG steering manifold is found, 
using the compliance times in the accomplishment instructions of 
PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N. 80-
0249 (includes CONFIRMATION SLIP), Rev. 1, dated May 27, 2009, 
replace the NLG steering manifold following (for S/N 1004 through 
1104) pages 1 through 8 dated March 1, 2006; 201, 202, 204, and 206
