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

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: 

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. 


sroberts on DSK5SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 191 / Wednesday, October 2, 2013 / Rules and Regulations 60675 

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: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Replacement ........................ Up to 2 work-hours × $85 per hour = $170 .................. Up to $36,552 .................... Up to $36,722. 

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.

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2013–0090; Directorate 

Identifier 2012–NM–149–AD; Amendment 

39–17595; AD 2013–19–13] 

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 747–100, 

747–100B, 747–100B SUD, 747–200B, 

747–200C, 747–300, 747–400, 747– 

400D, and 747SP series airplanes. This 

AD was prompted by reports of worn or 

incorrectly assembled latches on main 

deck escape slides installed on airplane 

doors. This AD requires determining if 

the latches are correctly assembled; and 

doing corrective actions if necessary. 

This AD also requires, for certain 

airplanes, modifications to the escape 

slide/rafts and escape slides. We are 

issuing this AD to prevent a latch hook 

moving from closed to open in an 

escape slide/raft or escape slide, which 

could result in the escape slide/raft or 

escape slide not deploying correctly in 

an emergency, or releasing/inflating into 

the passenger cabin and causing injury 

to passengers and crew. 

DATES: This AD is effective November 6, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this 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 February 8, 2013 (78 FR 

9346). The NPRM proposed to require 

determining if the latches on main deck 

escape slides installed on airplane doors 

are correctly assembled; and doing 

corrective actions if necessary. The 

NPRM also proposed to require, for 

certain airplanes, modifications to the 

escape slide/rafts and escape slides. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (78 FR 9346, 

February 8, 2013) and the FAA’s 

response to each comment. 

Request To Extend Compliance Time 

Delta Air Lines (DAL) requested that 

the compliance time in the NPRM (78 

FR 9346, February 8, 2013) be extended 

to 60 months. DAL stated that this will
