[Docket No. FAA-2014-0485; Directorate Identifier 2014-NM-093-AD]
RIN 2120-AA64


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.

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

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.
