ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777–200 and –300 series airplanes. This proposed AD was prompted by reports of cracked retract actuator fuse pins that can fail earlier than the previously determined safe life limit of the pins. A fractured retract actuator fuse pin can cause the main landing gear (MLG) to extend without restriction and attempt to lock into position under high dynamic loads. This proposed AD would require an inspection for the part number of the fuse pin, and replacement of the pin if necessary. We are proposing this AD to prevent structural damage to the side and drag brace lock assemblies, which could result in landing gear collapse during touchdown, rollout, or taxi. DATES: We must receive comments on this proposed AD by February 13, 2012. tkelley on DSK3SPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 19:18 Dec 29, 2011 Jkt 226001 You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received reports of cracked retract actuator fuse pins that can fail earlier than previously determined safe life limit of the pins. A fractured retract actuator fuse pin can cause the main landing gear (MLG) to extend without restriction and attempt to lock into position under high dynamic loads. Unrestricted MLG extension could cause structural damage to the side and drag brace lock assemblies. This condition, if not corrected, could result in structural damage to the side and drag brace lock assemblies, which could result in landing gear collapse during touchdown, rollout, or taxi. Relevant Service Information We reviewed Boeing Special Attention Service Bulletin 777–32– 0083, Revision 1, dated February 17, 2011. The service information describes procedures for inspecting the retract actuator fuse pin to identify the part number of the pin and, if an affected pin is found, replacing it with a new part number pin. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD affects 35 airplanes of U.S. registry.

SUPPLEMENTARY INFORMATION: Section 307 of the 2010 Act, requires that VA ‘‘establish a grant program to provide innovative transportation options to veterans in highly rural areas.’’ To comply with section 307 of the 2010 Act, VA will award grants to eligible entities to assist veterans in highly rural areas to travel to VA medical centers, and to otherwise assist in providing transportation in connection with the provision of VA medical care to these veterans. This proposed rule would establish the grant program in accordance with paragraph (a) of section 307 of the 2010 Act, and establish regulations for evaluating grant applications and otherwise administering the grant program in accordance with paragraph (b) of section 307 of the 2010 Act. Section 307(d) of the 2010 Act authorizes $3,000,000 of appropriated funds for each fiscal year beginning 2010 through 2014 to carry out the grant program. We would indicate this funding limitation for each of the fiscal years in a Notice of Fund Availability (NOFA) publication in the Federal Register, to adequately provide notice to eligible recipients of the grants. It is not necessary to include the funding limitation or to indicate the specific fiscal years for the program’s funding in the proposed rule, however, because the amount of authorized appropriations may change after fiscal year 2014 and Congress could extend the program past fiscal year 2014. Section 307 of the 2010 Act is not designated by Congress to be a pilot program, and the law does not otherwise contain a provision that it will cease to have effect after a specific date unless extended. By not including the funding limitation or the specific fiscal years the program is to be funded in the proposed rule, we would prevent having a regulation in the Code of Federal Regulations that appeared to restrict or stop the grant program beyond a certain date, when VA may still be compelled to administer the grant program. If funding ceases to be provided or the grant program is not extended beyond 2014, we would not E:\FR\FM\30DEP1.SGM 30DEP1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 777-200 and -300 series airplanes. 
This proposed AD was prompted by reports of cracked retract actuator 
fuse pins that can fail earlier than the previously determined safe 
life limit of the pins. A fractured retract actuator fuse pin can cause 
the main landing gear (MLG) to extend without restriction and attempt 
to lock into position under high dynamic loads. This proposed AD would 
require an inspection for the part number of the fuse pin, and 
replacement of the pin if necessary. We are proposing this AD to 
prevent structural damage to the side and drag brace lock assemblies, 
which could result in landing gear collapse during touchdown, rollout, 
or taxi.

DATES: We must receive comments on this proposed AD by February 13, 
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2011-1412; 
Directorate Identifier 2011-NM-158-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    We have received reports of cracked retract actuator fuse pins that 
can fail earlier than previously determined safe life limit of the 
pins. A fractured retract actuator fuse pin can cause the main landing 
gear (MLG) to extend without restriction and attempt to lock into 
position under high dynamic loads. Unrestricted MLG extension could 
cause structural damage to the side and drag brace lock assemblies. 
This condition, if not corrected, could result in structural damage to 
the side and drag brace lock assemblies, which could result in landing 
gear collapse during touchdown, rollout, or taxi.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletin 777-32-0083, 
Revision 1, dated February 17, 2011. The service information describes 
procedures for inspecting the retract actuator fuse pin to identify the 
part number of the pin and, if an affected pin is found, replacing it 
with a new part number pin.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 35 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                     hour = $340.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary pin 
replacements that would be required based on the results of the 
proposed inspection. We have no way of determining the number of 
aircraft that might need these replacements:

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),

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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 
airworthiness directive (AD):

The Boeing Company: Docket No. FAA-2011-1412; Directorate Identifier 
2011-NM-158-AD.

(a) Comments Due Date

    We must receive comments by February 13, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 777-200 and -300 
series airplanes, certificated in any category, as identified in 
Boeing Special Attention Service Bulletin 777-32-0083, Revision 1, 
dated February 17, 2011.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 32, Main landing gear.

(e) Unsafe Condition

    This AD was prompted by reports of cracked retract actuator fuse 
pins that can fail earlier than the previously determined safe life 
limit of the pins. A fractured retract actuator fuse pin can cause 
the main landing gear (MLG) to extend without restriction and 
attempt to lock into position under high dynamic loads. We are 
issuing this AD to prevent structural damage to the side and drag 
brace lock assemblies, which could result in landing gear collapse 
during touchdown, rollout, or taxi.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection of Retract Actuator Fuse Pin

    Within 6 months after the effective date of this AD: Inspect the 
part number of the fuse pins of the left and right MLG retract 
actuators, in accordance with the Accomplishment Instructions of 
Boeing Special Attention Service Bulletin 777-32-0083, Revision 1, 
dated February 17, 2011. A review of airplane maintenance records is 
acceptable in lieu of this inspection if the part number of the 
installed actuator fuse pin can be conclusively determined from that 
review.
    (1) If any retract actuator fuse pin having part number 
112W1769-3 is found installed, no further action is required by this 
paragraph for that fuse pin.
    (2) If any retract actuator fuse pin having part number 
112W1769-1 is found installed and the pin has accumulated more than 
10,000 total flight cycles as of the effective date of this AD: 
Within 6 months after the effective date of this AD, replace the 
fuse pin with a new part number 112W1769-3 fuse pin, in accordance 
with the Accomplishment Instructions of Boeing Special Attention 
Service Bulletin 777-32-0083, Revision 1, dated February 17, 2011.
    (3) If any retract actuator fuse pin having part number 
112W1769-1 is found installed and the pin has accumulated 8,000 or 
more, but fewer than or equal to 10,000 total flight cycles, as of 
the effective date of this AD: Before the accumulation of 10,000 
total flight cycles on the pin, or within 12 months after the 
effective date of this AD, whichever occurs later, replace the fuse 
pin with a new part number 112W1769-3 fuse pin, in accordance with 
the Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 777-32-0083, Revision 1, dated February 17, 2011.

[[Page 82212]]

    (4) If any retract actuator fuse pin having part number 
112W1769-1 is found installed and the pin has accumulated fewer than 
8,000 total flight cycles as of the effective date of this AD: 
Before the accumulation of 8,000 total flight cycles on the pin, or 
within 24 months after the effective date of this AD, whichever 
occurs later, replace the fuse pin with a new part number 112W1769-3 
fuse pin, in accordance with the Accomplishment Instructions of 
Boeing Special Attention Service Bulletin 777-32-0083, Revision 1, 
dated February 17, 2011.

(h) Parts Installation

    As of the effective date of this AD, no person may install a 
retract actuator fuse pin having P/N 112W1769-1 on any airplane.

(i) Credit for Actions Accomplished in Accordance With Previous Service 
Information

    Actions done before the effective date of this AD in accordance 
with Boeing Special Attention Service Bulletin 777-32-0083, dated 
February 5, 2009, are acceptable for compliance with the 
corresponding requirements of this AD.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in the Related Information 
section of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by Boeing 
Commercial Airplanes Organization Designation Authorization (ODA) 
that has been authorized by the Manager, Seattle ACO, to make those 
findings. For a repair method to be approved, the repair must meet 
the certification basis of the airplane, and the approval must 
specifically refer to this AD.
