ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for certain
The Boeing Company Model 737–600,
–700, –700C, –800, and –900 series
airplanes. This proposed AD was
prompted by reports in which a single,
undetected, erroneous radio altimeter
output caused the autothrottle to enter
landing flare retard mode prematurely
on approach. This proposed AD would
require removing certain autothrottle
computers and installing a new or
reworked autothrottle computer. We are
proposing this AD to prevent a single,
undetected, erroneous radio altimeter
output from causing premature
autothrottle landing flare retard and
subsequent loss of automatic speed
control, which could result in loss of
control of the airplane.
DATES: We must receive comments on
this proposed AD by April 17, 2014.
ADDRESSES: You may send comments,

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 received reports in which a single,
undetected, erroneous radio altimeter
output caused the autothrottle to enter
landing flare retard mode prematurely
on approach. The autothrottle computer
delivered on Boeing Model 737NG
airplanes listed in the applicability of
this proposed AD does not have an
autothrottle radio altimeter comparator
to inhibit landing flare retard mode and,
therefore, can enter landing flare retard
mode prematurely due to a single,
undetected, erroneous radio altimeter
signal. This condition, if not corrected,
could result in a single, undetected,
erroneous radio altimeter output,
causing premature autothrottle landing
flare retard and subsequent loss of
automatic speed control, which could
result in loss of control of the airplane.
Relevant Service Information
We reviewed Boeing Alert Service
Bulletin 737–22A1215, dated November
22, 2013. For information on the
procedures, see this service information
at https://www.regulations.gov by
searching for Docket No. FAA–2014–
0122.

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
This proposed AD would require
removing certain autothrottle computers
and installing a new or reworked
autothrottle computer as specified in the
service information described
previously.
Costs of Compliance
We estimate that this proposed AD
affects 497 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS

Labor cost
Parts cost

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.
mstockstill on DSK4VPTVN1PROD with PROPOSALS
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:

The Proposal
This action proposes to amend Title
14, Code of Federal Regulations (14
CFR), Part 71 by modifying Class E
airspace extending upward from 700
feet above the surface at Amery
Municipal Airport, Amery, WI, for
standard instrument approach
procedures at the airport. Airspace
reconfiguration is necessary due to the
decommissioning of the Ameron NDB
and the cancellation of the NDB
approach, thereby removing the 7.4-mile
segment north extending from the 6.4mile radius of the airport. Controlled
airspace is necessary for the safety and
management of IFR operations at the
airport.
Class E airspace areas are published

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
This proposed AD would require removing certain autothrottle
computers and installing a new or reworked autothrottle computer as
specified in the service information described previously.
Costs of Compliance
We estimate that this proposed AD affects 497 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Autothrottle computer replacement... 1 work-hour x $85 per $0 $85 $42,245
hour = $85.
----------------------------------------------------------------------------------------------------------------
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),
(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.

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. Amend Sec. 39.13 by adding the following new airworthiness
directive (AD):
The Boeing Company: Docket No. FAA-2014-0122; Directorate Identifier
2014-NM-002-AD.
(a) Comments Due Date
We must receive comments by April 17, 2014.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 737-600, -700, -
700C, -800, and -900 series airplanes, certificated in any category,
as identified in Boeing Alert Service Bulletin 737-22A1215, dated
November 22, 2013.
(d) Subject
Air Transport Association (ATA) of America Code 22, Auto Flight.
(e) Unsafe Condition
This AD was prompted by reports in which a single, undetected,
erroneous radio altimeter output caused the autothrottle to enter
landing flare retard mode prematurely on approach. We are issuing
this AD to prevent a single, undetected, erroneous radio altimeter
output from causing premature autothrottle landing flare retard and
subsequent loss of automatic speed control, which could result in
loss of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Replacement
Within 36 months after the effective date of this AD, do the
actions specified in paragraphs (g)(1) and (g)(2) of this AD, in
accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin 737-22A1215, dated November 22, 2013.
