Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2014–05– 

02 for certain The Boeing Company 

Model 737–100, –200, –200C, –300, 

–400, and –500 series airplanes. AD 

2014–05–02 required repetitive 

inspections for cracking and corrosion 

of the aft pressure bulkhead, repetitive 

inspections of the frame chord drain 

path for debris, and corrective actions if 

necessary; and, for certain airplanes, 

enlargement of frame chord drain holes. 

This AD requires the same actions as 

AD 2014–05–02, but revises a certain 

repetitive inspection interval to avoid a 

misunderstanding of the repetitive 

inspection interval for the aft pressure 

bulkhead. This AD was prompted by 

reports from operators expressing 

confusion regarding a certain repetitive 

inspection interval for the aft pressure 

bulkhead. We are issuing this AD to 

detect and correct corrosion or cracking 

of the aft pressure bulkhead, which 

could result in loss of the aft pressure 

bulkhead web and stiffeners, and 

consequent rapid decompression of the 

airplane. 

DATES: This AD is effective September 

22, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 27, 2002 (67 FR 36085, May

SUPPLEMENTARY INFORMATION: 

Discussion 

On February 18, 2014, we issued AD 

2014–05–02, Amendment 39–17775 (79 

FR 12045, March 4, 2014), for certain 

The Boeing Company Model 737–100, 

–200, –200C, –300, –400, and –500 

series airplanes. AD 2014–05–02 

required repetitive inspections for 

cracking and corrosion of the aft 

pressure bulkhead, repetitive 

inspections of the frame chord drain 

path for debris, and corrective actions if 

necessary; and, for certain airplanes, 

enlargement of frame chord drain holes. 

AD 2014–05–02 resulted from three 

reports of severe corrosion in the area 

affected by AD 2002–10–11, 

Amendment 39–12757 (67 FR 36085, 

May 23, 2002), which AD 2014–05–02 

superseded. We issued AD 2014–05–02 

to detect and correct corrosion or 

cracking of the aft pressure bulkhead, 

which could result in loss of the aft 

pressure bulkhead web and stiffeners, 

and consequent rapid decompression of 

the airplane. 

Actions Since AD 2014–05–02, 

Amendment 39–17775 (79 FR 12045, 

March 4, 2014) Was Issued 

Since we issued AD 2014–05–02, 

Amendment 39–17775 (79 FR 12045, 

March 4, 2014), we have received 

reports from operators expressing 

confusion regarding the repetitive 

inspection interval for the aft pressure 

bulkhead inspection that was required 

by paragraph (l)(2) of AD 2014–05–02. 

We are issuing this AD to detect and 

correct corrosion or cracking of the aft 

pressure bulkhead, which could result 

in loss of the aft pressure bulkhead web 

and stiffeners, and consequent rapid 

decompression of the airplane. 

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 the same actions 

that were required by AD 2014–05–02, 

Amendment 39–17775 (79 FR 12045, 

March 4, 2014), but we have revised the 


tkelley on DSK3SPTVN1PROD with RULES
52954 Federal Register / Vol. 79, No. 172 / Friday, September 5, 2014 / Rules and Regulations 

wording of the repetitive inspection 

interval for the aft pressure bulkhead 

specified in paragraph (l)(2) of this AD 

to clarify the required action. We have 

stated that the repetitive inspection 

interval must be repeated at intervals 

not to exceed 2 years. 

Additional Change to AD 2014–05–02, 

Amendment 39–17775 (79 FR 12045, 

March 4, 2014) 

We have corrected a typographical 

error in the supplemental type 

certificate number that is in paragraph 

(c)(2) of AD 2014–05–02, Amendment 

39–17775 (79 FR 12045, March 4, 2014). 

We have also added a statement to 

paragraphs (k) and (o) of this AD that for 

repaired areas, the required inspection 

may be accomplished without removal 

of the repairs. This change will not 

increase the economic burden on any 

operator, nor will it increase the scope 

of this AD. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because operators have been 

uncertain of the correct repetitive 

inspection interval for the aft pressure 

bulkhead inspection. Therefore, we find 

that notice and opportunity for prior 

public comment are impracticable 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 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

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–2014–0623, and directorate 

identifier 2014–NM–139–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 419 

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 [actions retained from AD 

2014–05–02, Amendment 39– 

17775 (79 FR 12045, March 4, 

2014)].

4 work-hours × $85 per hour = $ 

340 per inspection cycle.

$0 $340 per inspection 

cycle.

$142,460 per inspection 

cycle. 

The requirements of this AD add no 

additional economic burden. 

We estimate the following costs to do 

any necessary repairs that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these repairs. 

ON-CONDITION COSTS

Action Labor cost Parts 

cost 

Cost per 

product 

Repair [actions retained from AD 2014–05–02, Amendment 

39–17775 (79 FR 12045, March 4, 2014)].

Up to 136 work-hours × $85 per hour = Up to 

$11,560.

$5,217 Up to $16,777. 

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.

tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 79, No. 172 / Friday, September 5, 2014 / Rules and Regulations 52955 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends part 39 of the Federal 

Aviation Regulations (14 CFR part 39) as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

2014–05–02, Amendment 39–17775 (79 

FR 12045, March 4, 2014), and adding 

the following new AD: 

2014–18–02 The Boeing Company: 

Amendment 39–17966; Docket No.

2014–NM–139–AD. 

(a) Effective Date 

This AD is effective September 22, 2014. 

(b) Affected ADs 

This AD replaces AD 2014–05–02, 

Amendment 39–17775 (79 FR 12045, March 

4, 2014). 

(c) Applicability 

(1) This AD applies to The Boeing 

Company Model 737–100, –200, –200C,

_Libraryrgstc.nsf0be866b732f

6cf31086257b9700692796

$FILEST01219SE.pdf) does not affect the 

ability to accomplish the actions required by 

this AD. Therefore, for airplanes on which 

STC ST01219SE is installed, a ’’change in 

product’’ alternative method of compliance 

(AMOC) approval request is not necessary to 

comply with the requirements of 14 CFR 

39.17. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Unsafe Condition 

This AD was prompted by three reports of 

severe corrosion in the area affected by AD 

2002–10–11, Amendment 39–12757 (67 FR 

36085, May 23, 2002). We are issuing this AD 

to detect and correct corrosion or cracking of 

the aft pressure bulkhead, which could result 

in loss of the aft pressure bulkhead web and 

stiffeners, and consequent rapid

SUPPLEMENTARY INFORMATION: 

History 

On December 27, 2013, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to establish controlled airspace at 

Flagstaff, AZ (78 FR 78794). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. One comment was received from 

the National Business Aviation 

Association in support of the 

recommended change. 

Class E airspace designations are 

published in paragraph 6006, of FAA 

Order 7400.9X dated August 7, 2013, 

and effective September 15, 2013, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in that Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

establishing Class E en route domestic 

airspace extending upward from 1,200 

feet above the surface, at the Flagstaff 

VOR/DME navigation aid, Flagstaff, AZ, 

to accommodate IFR aircraft under 

control of Albuquerque Air Route 

Traffic Control Center (ARTCC) by 

vectoring aircraft from en route airspace 

to terminal areas. This action is 

necessary for the safety and 

management of IFR operations. 

The FAA has determined this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (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); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that only affects air traffic 

procedures and air navigation, it is 

certified this rule, when promulgated, 

does not have a significant economic 

impact on a substantial number of small 

entities under the criteria of the 

Regulatory Flexibility Act. The FAA’s 

authority to issue rules regarding 

aviation safety is found in Title 49 of the 

U.S. Code. Subtitle 1, Section 106 

discusses the authority of the FAA 

Administrator. Subtitle VII, Aviation 

Programs, describes in more detail the 

scope of the agency’s authority. This 

rulemaking is promulgated under the 

authority described in Subtitle VII, Part 

A, Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it establishes 

controlled airspace at the Flagstaff VOR/ 

DME navigation aid, Flagstaff, AZ. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1E, ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 311a. This airspace action is 

not expected to cause any potentially 

significant environmental impacts, and 

no extraordinary circumstances exist 

that warrant preparation of an 

environmental assessment.
