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 737–100, 

737–200, 737–200C, 737–300, 737–400, 

and 737–500 series airplanes. This AD 

was prompted by reports of cracking in 

the lower corners of the forward entry 

doorway and the upper corners of the 

airstairs cutout. This AD requires 

inspections for cracking of the forward 

entry doorway and airstairs cutout, and 

corrective actions if necessary. This AD 

also provides terminating action for the 

repetitive inspections. We are issuing 

this AD to detect and correct cracks in 

the lower corners of the forward entry 

door cutout and the upper corners of the 

airstairs cutout, which could progress 

and result in an inability to maintain 

cabin pressurization. 

DATES: This AD is effective May 4, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 4, 2015.

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 certain The Boeing Company 

Model 737–100, 737–200, 737–200C, 

737–300, 737–400, and 737–500 series 

airplanes. The NPRM published in the 

Federal Register on May 28, 2014 (79 

FR 30500). The NPRM was prompted by 

reports of cracking in the lower corners 

of the forward entry doorway and the 

upper corners of the airstairs cutout. 

The NPRM proposed to require 

inspections for cracking of the forward 

entry doorway and airstairs cutout, and 

corrective actions if necessary. The 

NPRM also proposed to provide 

terminating action for the repetitive 

inspections. We are issuing this AD to 

detect and correct cracks in the lower 

corners of the forward entry door cutout 

and the upper corners of the airstairs 

cutout, which could progress and result 

in an inability to maintain cabin 

pressurization. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM (79 FR 30500, 

May 28, 2014) and the FAA’s response 

to each comment. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

accomplishing the installation of 

winglets per supplemental type 

certificate (STC) ST01219SE (http://rgl.

faa.gov/Regulatory_and_Guidance_

Library/rgstc.nsf/0/082838ee177dbf62

862576a4005cdfc0/$FILE/

ST01219SE.pdf) does not affect the 

actions specified in the NPRM (79 FR 

30500, May 28, 2014). 

We concur with the commenter. We 

have redesignated paragraph (c) of the 

proposed AD (79 FR 30500, May 28, 

2014) as paragraph (c)(1) in this AD and 

added new paragraph (c)(2) to this AD 

to state that installation of STC 

ST01219SE (http://rgl.faa.gov/

Regulatory_and_Guidance_Library/

rgstc.nsf/0/082838ee177dbf6286

2576a4005cdfc0/$FILE/ST01219SE.pdf) 

does not affect the ability to accomplish 

the actions required by this final rule. 

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. 

Request to Clarify That Certain 

Inspections Are Not Required for Areas 

With Existing Repairs 

Southwest Airlines (SWA) requested 

that the NPRM (79 FR 30500, May 28, 

2014) be revised to clarify that the 

initial and repetitive inspections 

specified in paragraph (g)(1) of the 

proposed AD would not be required for 

locations that are common to existing 

repairs that were installed using the 

Boeing Model 737 structural repair 

manual (SRM) repairs identified in Part 

3, ‘‘Permanent Repair,’’ of Paragraph 

3.B., ‘‘Work Instructions,’’ of the 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 737– 

53–1083, Revision 4, dated December 

18, 2013. As an alternative to this 

clarification, SWA suggested that 

guidance be provided on how to address 

the existing repairs since the 

inspections proposed in paragraph (g)(1) 

of the proposed AD cannot be 

accomplished in the repaired areas. 

SWA observed that the applicability 

blocks in Repair 12 and Repair 13 of 

Boeing 737–300/400/500 SRM 53–10–01 

state that the inspections identified in 

Boeing Special Attention Service 

Bulletin 737–53–1083, Revision 4, dated 

December 18, 2013, are not necessary 

for the repaired areas. 

We agree that the inspections required 

by paragraph (g)(1) of this AD cannot be 

accomplished at locations where certain 

repairs have been installed. We have 

added a new paragraph (g)(3) to this AD 

and redesignated the subsequent 

paragraph as (g)(4). Paragraph (g)(3) of 

this AD clarifies that accomplishment of 

a permanent repair terminates the 

repetitive inspections required by 

paragraph (g)(1) of this AD for the 

repaired area only. 

Request for Alternative Inspection 

Methods 

SWA requested that the NPRM (79 FR 

30500, May 28, 2014) be revised to 


asabaliauskas on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 80, No. 60 / Monday, March 30, 2015 / Rules and Regulations 16559 

provide operators the option to request 

alternative inspection instructions from 

Boeing for areas with existing repairs 

that were approved by a Boeing 

Authorized Representative (AR). The 

inspections proposed in paragraph (g)(1) 

of the NPRM cannot be accomplished in 

areas with existing repairs. 

We do not agree to revise this AD to 

include a provision to provide operators 

the option to request alternative 

inspection instructions from Boeing. If 

there are existing repairs that were 

approved by a Boeing AR, and those 

existing repairs prevent 

accomplishment of the inspections 

required by paragraph (g)(1) of this AD, 

14 CFR 39.17 of the Federal Aviation 

Regulations requires an affected 

operator to obtain an AMOC from the 

FAA. Upon publication of this AD, the 

Manager of the Los Angeles Aircraft 

Certification Office will consider 

granting AMOC authority for this AD to 

the Boeing Commercial Airplanes 

Organization Designation Authorization 

(ODA). 

Request To Clarify That Inspections 

Are Not Required for Previously 

Repaired Areas 

Boeing requested that paragraph (g)(2) 

of the NPRM (79 FR 30500, May 28, 

2014) be revised to specify that the 

inspections required by paragraph (g)(1) 

of the NPRM are not required for Groups 

1 and 2 airplanes that have been 

repaired using the service information 

identified in paragraph (g)(2)(i), 

(g)(2)(ii), or (g)(2)(iii) of the NPRM. 

Boeing noted that, as currently written, 

paragraph (g)(2) of the NPRM would not 

require inspection of the unrepaired 

lower entry door and upper airstair 

corners and would contradict the 

inspections in the service information, 

which could lead to an unsafe 

condition. Boeing also pointed out that 

the inspection zones specified in the 

following service information do not 

include the repaired area(s). 

• Boeing Service Bulletin 737– 

531083, Revision 1, dated October 25, 

1985. 

• Boeing Service Bulletin 737– 

531083, Revision 2, dated March 17, 

1988. 

• Boeing Service Bulletin 737– 

531083, Revision 3, dated December 7, 

1989. 

For the reasons provided by the 

commenter we agree to revise paragraph 

(g)(2) of this AD to specify that ‘‘[T]he 

inspections required by paragraph (g)(1) 

of this AD are not required in the 

repaired area.’’ 

Request To Specify Inspection 

Locations 

Boeing requested that paragraph (g)(1) 

of the NPRM (79 FR 30500, May 28, 

2014) be revised to specify the locations 

that need to be inspected. The 

commenter stated that, as currently 

written, the inspection methods are 

specified but not the inspection 

locations. Boeing Special Attention 

Service Bulletin 737–53–1083, Revision 

4, dated December 18, 2013, provides 

different inspection methods based on 

the location of the inspection. Boeing 

suggested that the revision to paragraph 

(g)(1) state ‘‘[D]o the inspections 

specified in paragraphs (g)(1)(i), 

(g)(1)(ii), (g)(1)(iii), and (g)(1)(iv) of this 

AD and in accordance with Part 1 of the 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 737– 

53–1083, Revision 4. . . .’’ 

We do not agree it is necessary to 

specify inspection locations because 

paragraph (g)(1) of this AD already 

requires operators to do the inspections 

in accordance with Part 1 of the 

Accomplishment Instructions of Boeing 

Special Attention Service Bulletin 737– 

53–1083, Revision 5, dated July 22, 

2014. These accomplishment 

instructions include the specific 

inspection methods and the inspection 

locations. No change has been made to 

this AD in this regard. 

Request To Refer to Revised Service 

Information 

ANA and Europe Airpost requested 

that the material in Boeing Information 

Notice 737–53–1083 R04 IN 03 to 

Boeing Alert Service Bulletin 737–53– 

1083 be included in the final rule. The 

commenters noted that, based on the 

material in Boeing Information Notice 

737–53–1083 R04 IN 03 to Boeing 

Service Bulletin 737–53–1083, the 

inspection of the skin doubler required 

by paragraph (g)(1)(iii) of the NPRM (79 

FR 30500, May 28, 2014) would no 

longer be applicable to Group 4 

airplanes. The commenters explained 

that Boeing Special Attention Service 

Bulletin 737–53–1083, Revision 5, dated 

July 22, 2014, would incorporate the 

material in Boeing Information Notice 

737–53–1083 R04 IN 03. The 

commenters pointed out that operators 

might have to request AMOCs from the 

FAA if the final rule did not include 

this material and was issued prior to 

Boeing’s release of Boeing Special 

Attention Service Bulletin 737–53– 

1083, Revision 5, dated July 22, 2014. 

We agree that the material in 

Information Notice 737–53–1083 R04 IN 

03 to Boeing Service Bulletin 737–53– 

1083 is incorporated in Boeing Special 

Attention Service Bulletin 737–53– 

1083, Revision 5, dated July 22, 2014. 

Since the NPRM (79 FR 30500, May 28, 

2014) was published, Boeing has issued 

and we have reviewed Special Attention 

Service Bulletin 737–53–1083, Revision 

5, dated July 22, 2014. We have revised 

this AD to include Boeing Special 

Attention Service Bulletin 737–53– 

1083, Revision 5, dated July 22, 2014, as 

an additional source of service 

information. We have also included a 

new paragraph (k) in this AD, and 

redesignated the subsequent paragraphs 

accordingly, to provide credit for 

accomplishment of certain actions 

before the effective date of this AD using 

Boeing Special Attention Service 

Bulletin 737–53–1083, Revision 4, dated 

December 18, 2013. 

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 (79 FR 

30500, May 28, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 30500, 

May 28, 2014). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD.

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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 adding 

the following new airworthiness 

directive (AD): 

2015–06–07 The Boeing Company: 

Amendment 39–18125; Docket No. 

FAA–2014–0284; Directorate Identifier 

2014–NM–011–AD. 

(a) Effective Date 

This AD is effective May 4, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

(1) This AD applies to The Boeing 

Company Model 737–100, –200, –200C, 

–300, –400, and –500 series airplanes, 

certificated in any category, as identified in 

Boeing Special Attention Service Bulletin 

737–53–1083, Revision 5, dated July 22, 

2014. 

(2) Installation of Supplemental Type 

Certificate (STC) ST01219SE (http://rgl.faa.

gov/Regulatory_and_Guidance_Library/rgstc.

nsf/0/082838ee177dbf62862576a4005cdfc0/

$FILE/ST01219SE.pdf) does not affect the 

ability to accomplish the actions required by 

this AD. For airplanes on which STC 

ST01219SE (http://rgl.faa.gov/Regulatory_

and_Guidance_Library/rgstc.nsf/0/ebd1cec7b

301293e86257cb30045557a/$FILE/

ST01219SE.pdf) is installed, therefore, 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 reports of 

cracking in the lower corners of the forward 

entry doorway and the upper corners of the 

airstairs cutout. We are issuing this AD to 

detect and correct cracks in the lower corners 

of the forward entry door cutout and the 

upper corners of the airstairs cutout, which 

could progress and result in an inability to 

maintain cabin pressurization. 

(f) Compliance
