14 CFR Part 39

[Docket No. FAA-2014-0125; Directorate Identifier 2013-NM-119-AD; 
Amendment 39-17778; AD 2014-05-05]

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 777 airplanes. This AD requires, for certain 
airplanes, replacing radio altimeter transceivers with upgraded units, 
and, for all airplanes, replacing low range radio altimeter antennas 
with new antennas. This AD was prompted by operator reports of erratic 
low range radio altimeter (LRRA) operation while the airplane is 
airborne. We are issuing this AD to prevent adverse system responses 
and flight deck effects that could result in loss of controllability of 
the airplane or landing short of the runway during landing.

DATES: This AD is effective March 20, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 20, 
2014.
    We must receive comments on this AD by April 21, 2014.

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: 

Discussion

    We have received operator reports of erratic low range radio 
altimeter (LRRA) operation while the airplane is airborne. The symptoms 
of erratic LRRA can include the following:
     Large differences between captain's and first officer's 
radio altitudes or a negative altitude in air.
     ``NO LAND 3'' or ``NO AUTOLAND'' Engine Indication and 
Crew Alerting System (EICAS) message.
     Autopilot disconnect, inability to engage autopilot, or 
flight directors bias-out-of view.
     Autothrottle disconnect, autothrottle retard, or inability 
to engage autothrottle into SPD (Speed) mode.
     Unexpected configuration warnings after takeoff, during 
approach, or during go-around
     Missing or inappropriate aural height callouts
     Unavailability of auto speedbrake via ``AUTO SPEEDBRAKE'' 
EICAS message.
     Nuisance or missing Ground Proximity Warning System (GPWS) 
warnings.
     Electronic Engine Control (EEC) indicating ground mode and 
engine going to ground idle.
     Inability to engage Lateral Navigation (LNAV).
    Erratic LRRA operation events have been determined to possibly 
result from the following causes:
     Antenna alteration at the antenna level can create micro 
cracks on the electrical grounding connection, damage the coax cables 
or the coax connector center pin contact. Any one of these damages to 
the antenna assembly can affect the radio altimeter system 
functionality.
     The currently installed radio altimeter transceivers on 
some airplanes may not have adequate antenna monitoring capabilities 
for detecting antenna deterioration caused by environmental conditions 
or damage to the antenna during antenna alteration (which can result in 
breaks in the coaxial cables or damage to the coax connector).
    These conditions, if not corrected, could result in adverse system 
responses and flight deck effects that could result in loss of 
controllability of the airplane or landing short of the runway during 
landing. We are issuing this AD to correct the unsafe condition on 
these products.

Relevant Service Information

    We reviewed Boeing Alert Service Bulletin 777-34A0191, Revision 1, 
dated March 23, 2012, and Boeing Alert Service Bulletin 777-34A0192, 
dated December 14, 2012. For information on the procedures and 
compliance times, see this service information at http://www.regulations.gov by searching for Docket No. FAA-2014-0125.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information identified previously.

FAA's Justification and Determination of the Effective Date

    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future. Therefore, we find that 
notice and opportunity for prior public comment are unnecessary and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2014-0125 and 
Directorate Identifier 2013-NM-119-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 0 airplanes of U.S. registry.
    We estimate the following costs to comply with this 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

    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 that 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),
    (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.
