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 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, 

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– 

2014–0122; Directorate Identifier 2014– 

NM–002–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 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Proposed Rules 11729 

closing date and may amend this 

proposed 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 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 http://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

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Autothrottle computer replacement ................. 1 work-hour × $85 per hour = $85 ................. $0 $85 $42,245 

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 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 6.4- 

mile radius of the airport. Controlled 

airspace is necessary for the safety and 

management of IFR operations at the 

airport.
