RIN 2120–AA64 

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 737–100, 

–200, –200C, –300, –400, and –500 

series airplanes. This proposed AD was 

prompted by reports of fatigue cracks 

found in the upper corners of the 

forward entry door skin cutout. This 

proposed AD would require repetitive 

inspections for cracking in the upper 

corners of the forward entry door skin 

cutout, and repair if necessary. 

Accomplishment of this repair or a 

preventive modification would 

terminate the repetitive inspections. 

This proposed AD also would require 

repetitive post-modification and postrepair inspections. We are proposing 

this AD to detect and correct cracking in 

the doorway upper corners, which 

could result in cabin depressurization. 

DATES: We must receive comments on 

this proposed AD by July 28, 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– 

2014–0339; Directorate Identifier 2014– 

NM–025–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 

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 of fatigue cracks 

found in the upper corners of the 

forward entry door skin cutout. The 

airplanes had accumulated between 

33,150 and 76,242 total flight cycles. 

The cracking is caused by fatigue from 

cabin pressure loads. This condition, if 

not corrected, could result in cabin 

depressurization. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 737–53A1163, Revision 1, 

dated January 8, 2014. For information 

on the procedures and compliance 

times, see this service information at 

http://www.regulations.gov by searching 

for Docket No. FAA–2014–0339. 

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 

accomplishing the repetitive inspections 

for cracking in the upper corners of the 

forward entry door skin cutout, and 

repair if necessary, as specified in the 

service information described 

previously, except as discussed under 

‘‘Difference Between this Proposed AD 

and the Service Information.’’ 

The phrase ‘‘corrective actions’’ is 

used in this proposed AD. ‘‘Corrective 

actions’’ are actions that correct or 

address any condition found. Corrective 

actions in an AD could include, for 

example, repairs. 

Explanation of Post-Modification and 

Post-Repair Inspection 

The Accomplishment Instructions of 

Boeing Alert Service Bulletin 737– 

53A1163, Revision 1, dated January 8, 

2014, states that Group 1 and 2 

airplanes having the repair or 

preventive modification installed in 

accordance with Boeing Service Bulletin 

737–53–1163, dated December 21, 1993, 


wreier-aviles on DSK6TPTVN1PROD with NOTICES
Federal Register / Vol. 79, No. 112 / Wednesday, June 11, 2014 / Proposed Rules 33485 

are not required to be inspected; 

however, this AD would require 

inspections of Group 1 and 2 airplanes 

in accordance with paragraph (i) of this 

AD, which corresponds with table 3 of 

paragraph 1.E., ‘‘Compliance,’’ of Boeing 

Alert Service Bulletin 737–53A1163, 

Revision 1, dated January 8, 2014. 

Difference Between This Proposed AD 

and the Service Information 

The service bulletin specifies to 

contact the manufacturer for 

instructions on how to inspect and 

repair certain conditions, but this 

proposed AD would require inspecting 

and repairing those conditions in one of 

the following ways: 

• In accordance with a method that 

we approve; or 

• Using data that meet the 

certification basis of the airplane, and 

that have been approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) whom 

we have authorized to make those 

findings. 

Costs of Compliance 

We estimate that this proposed AD 

affects 371 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS: REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection ................................ 3 work-hours × $85 per hour = $255 ........................................ $0 $255 $94,605 

ESTIMATED COSTS: OPTIONAL ACTIONS

Action Labor cost Parts cost Cost per 

product 

Preventive modification ................ 44 work-hours × $85 per hour = $3,740 ........................................... Up to $3,912 ....... Up to $7,652. 

We estimate the following costs to do 

any necessary repairs 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 these repairs: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Repair ........................................... 60 work-hours × $85 per hour = $5,100 ........................................... Up to $4,964 ....... Up to $10,064. 

We have received no definitive data 

that would enable us to provide a cost 

estimate for the post-repair or postpreventive modification inspections 

specified in this proposed 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 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,
