SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM published in the Federal Register on October 10, 2012 (77 FR 61548). The NPRM proposed to require performing a general visual inspection to determine if a certain angle of attack (AOA) sensor with a paddle type vane is installed, and, for affected sensors, performing an operational test of the stall warning system, and replacing the AOA sensor with a new sensor if necessary. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (77 FR 61548, October 10, 2012) and the FAA’s response to each comment. Supportive Comments United Airlines and Air Line Pilots Association, International supported the NPRM (77 FR 61548, October 10, 2012). Request To Allow Credit for Certain ‘‘C’’ Check Actions Boeing requested that paragraph (f), ‘‘Compliance,’’ of the NPRM (77 FR 61548, October 10, 2012) be modified. Boeing stated it recommends the NPRM specifically state that if the maintenance planning document (MPD) ‘‘C’’ check task associated with the stall warning system has been accomplished within the last 15 months, or if one is scheduled within the compliance time, it can take the place of the required inspection. Boeing stated that the intent of the NPRM is then satisfied and no further inspection is required. Boeing also stated that the compliance statement in the Boeing service information is identical to the ‘‘SRP 7X7–34–0114’’ final compliance recommendation submitted to the FAA and it has been agreed upon. We partially agree with Boeing’s request. We agree with the intent of the request that the stall warning system test may be accomplished in lieu of the required inspection of the AOA sensor. However, because maintenance documents vary among operators, operators will have to submit data substantiating that the change would provide an acceptable level of safety. We have added a new paragraph (h) to this AD to allow accomplishment of this optional method of compliance in accordance with a method approved by the FAA. We have redesignated subsequent paragraphs accordingly. determined from that review without any doubt. We disagree with Lufthansa Technik’s request. It is the FAA’s intent with this AD to require determination of the type of AOA vanes installed on the airplane by an actual physical inspection of the AOA vane installation. For purposes of correcting a potential unsafe condition in the AOA vanes, the FAA considers actual physical inspection of the type of AOA vanes installed to be the most reliable method of determining what type of vane is installed. Although airplane maintenance records may in some cases document the AOA vane installation, they may also contain incorrect or outdated information, or be incorrectly interpreted (for example, by misreading the installed part number, or misunderstanding part number effectivity in the service information). Although it is true that in some cases the FAA has allowed a review of the maintenance records in lieu of an inspection, the physical inspection of the AOA in this case is far more reliable than the record check and it can be performed easily. We have not changed this AD in this regard. Request To Review the Maintenance Records in Lieu of the Inspection Lufthansa Technik AG requested that a review of the maintenance records be allowed in lieu of the inspection. Lufthansa Technik stated that in many cases it is possible to determine the part number installed from the airplane maintenance documents. Lufthansa Technik stated that the Boeing delivery documents contain a list with part numbers of the AOA sensors that are installed at airplane delivery. Lufthansa Technik stated that in the case of an AOA sensor being changed or replaced after delivery, it will be recorded in the airplane maintenance records. Lufthansa Technik also stated that some operators keep databases with the part numbers and serial numbers currently installed on their airplanes. Lufthansa Technik stated that in order to avoid incorrect results of the maintenance reviews due to incomplete or unclear maintenance records, the option should be limited to those cases where the part number of the sensors can be Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously— and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 61548, October 10, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 61548, October 10, 2012). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Costs of Compliance We estimate that this AD affects 1,013 airplanes of U.S. registry. We estimate the following costs to comply with this AD: sroberts on DSK5SPTVN1PROD with RULES ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspection ................................ 3 work-hours × $85 per hour = $255 ..................................... $0 $255 $258,315.

We have no way of 60675 determining the number of aircraft that might need this replacement: ON-CONDITION COSTS Action Labor cost Parts cost Replacement ........................ Up to 2 work-hours × $85 per hour = $170 .................. Up to $36,552 .................... 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. sroberts on DSK5SPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

14 CFR Part 39

[Docket No. FAA-2012-1041; Directorate Identifier 2011-NM-272-AD; 
Amendment 39-17590; AD 2013-19-08]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 727 airplanes; Model 737-100, -200, and -200C 
series airplanes; and Model 747-100, -100B, -100B SUD, -200B, -200C, -
200F, -300, -400, -400D, -400F, 747SR, and 747SP series airplanes. This 
AD was prompted by a report of an activation of the control column 
shaker during takeoff. This AD requires performing a general visual 
inspection to determine if a certain angle of attack (AOA) sensor with 
a paddle type vane is installed, and, for affected sensors, performing 
an operational test of the stall warning system, and replacing the AOA 
sensor with a new sensor if necessary. We are issuing this AD to 
prevent erroneous activation of the control column shaker during 
takeoff, which could result in runway overrun, failure to clear terrain 
or obstacles after takeoff, or reduced controllability of the airplane.

DATES: This AD is effective November 6, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 6, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM published in the Federal Register on October 10, 2012 (77 FR 
61548). The NPRM proposed to require performing a general visual 
inspection to determine if a certain angle of attack (AOA) sensor with 
a paddle type vane is installed, and, for affected sensors, performing 
an operational test of the stall warning system, and replacing the AOA 
sensor with a new sensor if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 61548, October 10, 2012) and the FAA's response to each comment.

Supportive Comments

    United Airlines and Air Line Pilots Association, International 
supported the NPRM (77 FR 61548, October 10, 2012).

Request To Allow Credit for Certain ``C'' Check Actions

    Boeing requested that paragraph (f), ``Compliance,'' of the NPRM 
(77 FR 61548, October 10, 2012) be modified. Boeing stated it 
recommends the NPRM specifically state that if the maintenance planning 
document (MPD) ``C'' check task associated with the stall warning 
system has been accomplished within the last 15 months, or if one is 
scheduled within the compliance time, it can take the place of the 
required inspection. Boeing stated that the intent of the NPRM is then 
satisfied and no further inspection is required. Boeing also stated 
that the compliance statement in the Boeing service information is 
identical to the ``SRP 7X7-34-0114'' final compliance recommendation 
submitted to the FAA and it has been agreed upon.
    We partially agree with Boeing's request. We agree with the intent 
of the request that the stall warning system test may be accomplished 
in lieu of the required inspection of the AOA sensor. However, because 
maintenance documents vary among operators, operators will have to 
submit data substantiating that the change would provide an acceptable 
level of safety. We have added a new paragraph (h) to this AD to allow 
accomplishment of this optional method of compliance in accordance with 
a method approved by the FAA. We have redesignated subsequent 
paragraphs accordingly.

Request To Review the Maintenance Records in Lieu of the Inspection

    Lufthansa Technik AG requested that a review of the maintenance 
records be allowed in lieu of the inspection. Lufthansa Technik stated 
that in many cases it is possible to determine the part number 
installed from the airplane maintenance documents. Lufthansa Technik 
stated that the Boeing delivery documents contain a list with part 
numbers of the AOA sensors that are installed at airplane delivery. 
Lufthansa Technik stated that in the case of an AOA sensor being 
changed or replaced after delivery, it will be recorded in the airplane 
maintenance records. Lufthansa Technik also stated that some operators 
keep databases with the part numbers and serial numbers currently 
installed on their airplanes. Lufthansa Technik stated that in order to 
avoid incorrect results of the maintenance reviews due to incomplete or 
unclear maintenance records, the option should be limited to those 
cases where the part number of the sensors can be determined from that 
review without any doubt.
    We disagree with Lufthansa Technik's request. It is the FAA's 
intent with this AD to require determination of the type of AOA vanes 
installed on the airplane by an actual physical inspection of the AOA 
vane installation. For purposes of correcting a potential unsafe 
condition in the AOA vanes, the FAA considers actual physical 
inspection of the type of AOA vanes installed to be the most reliable 
method of determining what type of vane is installed. Although airplane 
maintenance records may in some cases document the AOA vane 
installation, they may also contain incorrect or outdated information, 
or be incorrectly interpreted (for example, by misreading the installed 
part number, or misunderstanding part number effectivity in the service 
information). Although it is true that in some cases the FAA has 
allowed a review of the maintenance records in lieu of an inspection, 
the physical inspection of the AOA in this case is far more reliable 
than the record check and it can be performed easily. We have not 
changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously--and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 61548, October 10, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 61548, October 10, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 1,013 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
this replacement:

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.
