ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2007–13– 05, which applies to all The Boeing Company Model 777 airplanes. AD 2007–13–05 currently requires repetitive measurements of the freeplay of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. Since we issued AD 2007–13–05, the manufacturer determined that the procedure for the rudder freeplay inspection does not properly detect excessive freeplay in the rudder control load loop. This proposed AD would require repetitive freeplay inspections and lubrication of the right and left elevators, rudder, and rudder tab; and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct flutter, which can cause damage to the control surface structure and consequent loss of control of the airplane. DATES: We must receive comments on this proposed AD by September 12, 2014. SUMMARY: 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 http://www.regulations.gov.

Discussion On April 11, 2007, we issued AD 2007–13–05, Amendment 39–15109 (72 FR 33856, June 20, 2007), for all The Boeing Company Model 777 airplanes. AD 2007–13–05 requires repetitive measurement of the freeplay of the right and left elevators, rudder, and rudder tab; and related investigative and corrective actions if necessary. AD PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 43981 2007–13–05 also requires repetitive lubrication of the elevator, rudder, and rudder tab components. AD 2007–13–05 resulted from reports of freeplayinduced vibration of unbalanced control surfaces. We issued AD 2007–13–05 to detect and correct flutter, which can cause damage to the control surface structure and consequent loss of control of the airplane. Actions Since AD 2007–13–05, Amendment 39–15109 (72 FR 33856, June 20, 2007) Was Issued Since we issued AD 2007–13–05, Amendment 39–15109 (72 FR 33856, June 20, 2007), the manufacturer determined that the procedure for the rudder freeplay inspection does not properly detect excessive freeplay in the rudder control load loop. Relevant Service Information We reviewed Boeing Special Attention Service Bulletin 777–27– 0062, Revision 2, dated January 27, 2014. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0485. 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 the same type design. Proposed AD Requirements Although this proposed AD does not explicitly restate the requirements of AD 2007–13–05, Amendment 39–15109 (72 FR 33856, June 20, 2007), this proposed AD would retain all requirements of AD 2007–13–05. Those requirements are referenced in the service information identified previously, which, in turn, is referenced in paragraphs (g) and (h) of this proposed AD. This proposed AD would require repetitive inspections (measurements) of the freeplay of the right and left elevators, rudder, and rudder tab; and related investigative and corrective actions if necessary. This proposed AD would also require repetitive lubrication of the elevator, rudder, and rudder tab components. The phrase ‘‘corrective actions’’ is used in this proposed AD. ‘‘Corrective actions’’ are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs. E:\FR\FM\29JYP1.SGM 29JYP1 43982 Federal Register / Vol. 79, No. 145 / Tuesday, July 29, 2014 / Proposed Rules Costs of Compliance The new actions of this proposed AD would add no additional economic burden to that imposed by AD 2007–13– 05, Amendment 39–15109 (72 FR We estimate that this proposed AD affects 142 airplanes of U.S. registry. 33856, June 20, 2007). The current costs for this AD are repeated for the convenience of affected operators, as follows: ESTIMATED COSTS Action Labor cost Measurement (inspection), elevator. Lubrication, elevator 4 work-hours × $85 per hour = $340 per measurement (inspection) cycle. 17 work-hours × $85 per hour = $1,445 per lubrication cycle. 4 work-hours × $85 per hour = $340 per measurement (inspection) cycle. 7 work-hours × $85 per hour = $595 per lubrication cycle. 3 work-hours × $85 per hour = $255 per measurement (inspection) cycle. $0 5 work-hours × $85 per hour = $425 per lubrication cycle. Measurement (inspection), rudder. Lubrication, rudder ... Measurement (inspection), rudder tab. Lubrication, rudder tab. We have received no definitive data that would enable us to provide cost estimates for the on-condition corrective actions specified in this proposed AD. 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. rmajette on DSK2TPTVN1PROD with PROPOSALS Regulatory Findings 15:00 Jul 28, 2014 Cost per product Cost on U.S. operators $340 per measurement (inspection) cycle. $1,445 per lubrication cycle ...... $48,280 per measurement (inspection) cycle. $205,190 per lubrication cycle. $340 per measurement (inspection) cycle. $595 per lubrication cycle ......... $48,280 per measurement (inspection) cycle. $84,490 per lubrication cycle. 0 $255 per measurement (inspection) cycle. $36,210 per measurement (inspection) cycle. 0 $425 per lubrication cycle ......... $60,350 per lubrication cycle. 0 0 0 (2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) 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.

AD 2012–19–11 currently requires incorporating design changes to improve the reliability of the cabin altitude warning system by installing a redundant cabin altitude pressure switch, replacing the aural warning module (AWM) with a new or reworked AWM, and changing certain wire bundles or connecting certain previously capped and stowed wires as necessary. For certain airplanes, AD 2012–19–11 also requires prior or concurrent incorporation of related design changes by modifying the instrument panels, installing light assemblies, modifying the wire bundles, and installing a new circuit breaker, as necessary. Since we issued AD 2012– 19–11, we have determined that certain airplanes were not included in the requirement to incorporate related design changes. This proposed AD would add, for certain airplanes, a requirement to incorporate related design changes. This proposed AD also, for certain airplanes, no longer gives credit for accomplishing certain previous actions. We are proposing this AD to prevent the loss of cabin altitude warning, which could delay flightcrew recognition of a lack of cabin pressurization, and could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2007-13-
05, which applies to all The Boeing Company Model 777 airplanes. AD 
2007-13-05 currently requires repetitive measurements of the freeplay 
of the right and left elevators, rudder, and rudder tab, and related 
investigative and corrective actions if necessary. Since we issued AD 
2007-13-05, the manufacturer determined that the procedure for the 
rudder freeplay inspection does not properly detect excessive freeplay 
in the rudder control load loop. This proposed AD would require 
repetitive freeplay inspections and lubrication of the right and left 
elevators, rudder, and rudder tab; and related investigative and 
corrective actions if necessary. We are proposing this AD to detect and 
correct flutter, which can cause damage to the control surface 
structure and consequent loss of control of the airplane.

DATES: We must receive comments on this proposed AD by September 12, 
2014.

Discussion

    On April 11, 2007, we issued AD 2007-13-05, Amendment 39-15109 (72 
FR 33856, June 20, 2007), for all The Boeing Company Model 777 
airplanes. AD 2007-13-05 requires repetitive measurement of the 
freeplay of the right and left elevators, rudder, and rudder tab; and 
related investigative and corrective actions if necessary. AD 2007-13-
05 also requires repetitive lubrication of the elevator, rudder, and 
rudder tab components. AD 2007-13-05 resulted from reports of freeplay-
induced vibration of unbalanced control surfaces. We issued AD 2007-13-
05 to detect and correct flutter, which can cause damage to the control 
surface structure and consequent loss of control of the airplane.

Actions Since AD 2007-13-05, Amendment 39-15109 (72 FR 33856, June 20, 
2007) Was Issued

    Since we issued AD 2007-13-05, Amendment 39-15109 (72 FR 33856, 
June 20, 2007), the manufacturer determined that the procedure for the 
rudder freeplay inspection does not properly detect excessive freeplay 
in the rudder control load loop.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletin 777-27-0062, 
Revision 2, dated January 27, 2014. For information on the procedures 
and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0485.

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 the same type design.

Proposed AD Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2007-13-05, Amendment 39-15109 (72 FR 33856, June 
20, 2007), this proposed AD would retain all requirements of AD 2007-
13-05. Those requirements are referenced in the service information 
identified previously, which, in turn, is referenced in paragraphs (g) 
and (h) of this proposed AD.
    This proposed AD would require repetitive inspections 
(measurements) of the freeplay of the right and left elevators, rudder, 
and rudder tab; and related investigative and corrective actions if 
necessary. This proposed AD would also require repetitive lubrication 
of the elevator, rudder, and rudder tab components.
    The phrase ``corrective actions'' is used in this proposed AD. 
``Corrective actions'' are actions that correct or address any 
condition found. Corrective actions in an AD could include, for 
example, repairs.

[[Page 43982]]

Costs of Compliance

    We estimate that this proposed AD affects 142 airplanes of U.S. 
registry. The new actions of this proposed AD would add no additional 
economic burden to that imposed by AD 2007-13-05, Amendment 39-15109 
(72 FR 33856, June 20, 2007). The current costs for this AD are 
repeated for the convenience of affected operators, as follows:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition corrective actions specified in 
this proposed AD.

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 have 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 that the 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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

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

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 removing Airworthiness Directive (AD) 
2007-13-05, Amendment 39-15109 (72 FR 33856, June 20, 2007), and adding 
the following new AD:

The Boeing Company: Docket No. FAA-2014-0485; Directorate Identifier 
2014-NM-093-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by September 12, 
2014.

(b) Affected ADs

    This AD replaces AD 2007-13-05, Amendment 39-15109 (72 FR 33856, 
June 20, 2007).

(c) Applicability

    This AD applies to The Boeing Company Model 777-200, -200LR, -
300, and -300ER series airplanes, certificated in any category, as 
identified in paragraphs (c)(1) and (c)(2) of this AD.
    (1) Airplanes having a Variable Number identified in paragraph

certificate of airworthiness on or after January 27, 2014.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Unsafe Condition

    This AD was prompted by the manufacturer's determination that 
the procedure for the rudder freeplay inspection does not properly 
detect excessive freeplay in the rudder control load loop. We are 
issuing this AD to detect and correct flutter, which can cause 
damage to the control surface structure and consequent loss of 
control of the airplane.

(f) Compliance

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

(g) Repetitive Inspections of Elevators, Rudder, and Rudder Tab

    At the applicable times specified in tables 1, 2, and 3 of 
paragraph 1.E. ``Compliance,'' of Boeing Special Attention Service 
Bulletin 777-27-0062, Revision 2, dated January 27, 2014, except as 
provided by paragraph (i) of this AD: Inspect the freeplay of the 
right and left elevators, rudder, and rudder tab by accomplishing 
all of the actions specified in Parts 1, 3, and 5 of the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 777-27-0062, Revision 2, dated January 27, 2014. Repeat the 
inspections thereafter at the intervals

specified in tables 1, 2, and 3 of paragraph 1.E. ``Compliance,'' of 
Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, 
dated January 27, 2014. If during any inspection required by this 
paragraph, the rudder freeplay exceeds any applicable measurement 
specified in Part 1, 3, or 5 of the Accomplishment Instructions of 
Boeing Special Attention Service Bulletin 777-27-0062, Revision 2, 
dated January 27, 2014, before further flight, do the applicable 
corrective actions in accordance with Parts 1, 3, or 5 of the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 777-27-0062, Revision 2, dated January 27, 2014.

(h) Repetitive Lubrication

    At the applicable times specified in tables 1, 2, and 3 of 
paragraph 1.E. ``Compliance,'' of Boeing Special Attention Service 
Bulletin 777-27-0062, Revision 2, dated January 27, 2014, except as 
provided by paragraph (i) of this AD: Lubricate the elevator
