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 cracking 

in certain areas. This proposed AD 

would require repetitive inspections for 

cracking of the skin assembly and bear 

strap of the forward airstair stowage 

doorway; post-repair and postmodification inspections for certain 

airplanes; and related investigative and 

corrective actions, if necessary. This 

proposed AD would also provide 

optional terminating actions for certain 

repetitive inspections. We are proposing 

this AD to detect and correct fatigue 

cracking, which could result in rapid 

loss of cabin pressure. 

DATES: We must receive comments on 

this proposed AD by June 16, 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– 

2014–0257; Directorate Identifier 2014– 

NM–012–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 

cracking in the skin assembly and bear 

strap at the aft lower corner of the 

forward airstair stowage doorway. The 

cracking was caused by fatigue from 

cyclic pressurization loading. At the 

time of crack detection, the airplanes 

had accumulated between 16,177 and 

74,036 total flight cycles. This 

condition, if not corrected, could result 

in rapid loss of cabin pressure. 

Related Rulemaking 

AD 90–06–02, Amendment 39–6489 

(Docket No. 89–NM–67–AD; 55 FR 

8372, March 7, 1990), mandates certain 

structural modifications for Model 737– 

100, –200, –200C series airplanes. AD 

98–11–04 R1, Amendment 39–10984 (64 

FR 987, January 7, 1999); AD 2008–08– 

23, Amendment 39–15477 (73 FR 

21237, April 21, 2008); and AD 2008– 

09–13, Amendment 39–15494 (73 FR 

24164, May 2, 2008); are supplemental 

structural inspection (SSI) program ADs 

that contain inspection requirements 

that are near or overlap the inspection 

areas that this proposed AD would 

require. The modification mandated by 

AD 90–06–02 and the inspections 

mandated by the exploratory SSI 

program ADs are not sufficient to 

address the unsafe condition identified 

in this proposed AD. 

Relevant Service Information 

We reviewed Boeing Service Bulletin 

737–53–1058, Revision 4, dated January 

9, 2014. For information on the 

procedures and compliance times, see 

this service information at http://

www.regulations.gov by searching for 

Docket No. FAA–2014–0257. 

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 actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between this Proposed AD 

and the Service Information.’’ This 

proposed AD would also provide 

optional terminating actions for certain 

repetitive inspections. 

The phrase ‘‘related investigative 

actions’’ is used in this proposed AD. 

‘‘Related investigative actions’’ are 

follow-on actions that (1) are related to 

the primary actions, and (2) further 

investigate the nature of any condition 

found. Related investigative actions in 

an AD could include, for example, 

inspections. 

The phrase ‘‘corrective actions’’ is 

used in this proposed AD. ‘‘Corrective 

actions’’ are actions that correct or 

address any condition found. Corrective 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 84 / Thursday, May 1, 2014 / Proposed Rules 24629 

actions in an AD could include, for 

example, repairs. 

Differences Between This Proposed AD 

and the Service Information 

The service information specifies to 

contact the manufacturer for 

instructions on how to repair certain 

conditions, but this proposed AD would 

require 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 132 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Inspection ....................... 5 work-hours × $85 per hour = $425 per inspection cycle.None ........ $425 per inspection 

cycle.

$56,100 per inspection 

cycle. 

We have received no definitive data 

that would enable us to provide cost 

estimates for any on-condition actions 

specified in this proposed AD. We have 

no way of determining the number of 

aircraft that might need this repair. 

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.
