Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 98–22–10, 

which applies to certain The Boeing 

Company Model 737–100, –200, –200C, 

and –300 series airplanes. AD 98–22–10 

currently requires repetitive inspections 

for cracking of the aft frame and frame 

support structure of the forward service 

doorway, and repair if necessary. AD 

98–22–10 also provides for an optional 

terminating action for the repetitive 

inspection requirements of that AD. 

Since we issued AD 98–22–10, we have 

determined that additional inspections 

are needed, and that additional 

airplanes may be subject to the 

identified unsafe condition. This 

proposed AD would add inspections 

and add airplanes to the applicability. 

For certain airplanes, this proposed AD 

provides a preventive modification, 

which would terminate the repetitive 

inspections. We are proposing this AD 

to detect and correct fatigue cracking of 

the aft frame and frame support 

structure of the forward service doorway 

around the six doorstop fittings, which 

could result in door deflection and loss 

of pressurization. 

DATES: We must receive comments on 

this proposed AD by October 10, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

On October 19, 1998, we issued AD 

98–22–10, Amendment 39–10858 (63 

FR 57240, October 27, 1998), for certain 

The Boeing Company Model 737–100, 

–200, –200C, and –300 series airplanes. 

AD 98–22–10 requires repetitive 

inspections to detect cracking of the aft 

frame and aft frame support structure of 

the forward service doorway, and repair 

if necessary. AD 98–22–10 resulted from 

reports of fatigue cracking of the aft 

frame and frame support structure of the 

forward service doorway. We issued AD 

98–22–10 to prevent fatigue cracking of 

the aft frame and frame support 

structure of the forward service 

doorway, which could result in loss of 

the door, and consequent rapid 

decompression of the fuselage. 

Tables 9 through 12 in paragraph 1.E., 

‘‘Compliance,’’ of Boeing Alert Service 

Bulletin 737–53A1108, Revision 7, 

dated July 7, 2014, specify post-repair 

inspections, which may be used in 

support of compliance with section 

121.1109(c)(2) or 129.109(b)(2) of the 

Federal Aviation Regulations (14 CFR 

121.1109(c)(2) or 129.109(b)(2)). 

However, this NPRM does not propose 

to require those post-repair inspections. 

This difference has been coordinated 

with Boeing. 

Actions Since AD 98–22–10, 

Amendment 39–10858 (63 FR 57240, 

October 27, 1998), Was Issued 

Since we issued AD 98–22–10, 

Amendment 39–10858 (63 FR 57240, 

October 27, 1998), we received reports 

of cracking in the forward galley service 

doorway surround structure between 

body station (STA) 332.1 and STA 344, 

which are outside the inspection area of 

AD 98–22–10, and we have received 

reports that cracking has been 

discovered on airplanes outside the 

applicability of AD 98–22–10. We have 

determined that additional inspections 

are needed, and that additional 

airplanes are subject to the identified 

unsafe condition. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 737–53A1108, Revision 7, 

dated July 7, 2014. For information on 

the procedures and compliance times,

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0572. 

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 

Although this proposed AD does not 

explicitly state the requirements of AD 

98–22–10, Amendment 39–10858 (63 

FR 57240, October 27, 1998), this 

proposed AD would retain certain 

requirements of AD 98–22–10. Those 

requirements are referenced in the 

service information identified 

previously, which, in turn, is referenced 

in paragraphs (g) and (h) of this 

proposed AD. This proposed AD would 

require additional inspections and add 

airplanes to the applicability. 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.’’ 

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’’ correct or address any 

condition found. Corrective actions in 

an AD could include, for example, 

repairs. 

Differences Between This Proposed AD 

and the Service Information 

Where Boeing Alert Service Bulletin 

737–53A1108, Revision 7, dated July 7, 

2014, specifies to contact the 

manufacturer for instructions on how to 

repair certain conditions, 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 419 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

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

Inspection .......................... Up to 28 work-hours × $85 

per hour = $2,380 per 

inspection cycle.

None .................................. Up to $2,380 per inspection cycle.Up to $997,220 per inspection cycle. 

ESTIMATED COSTS FOR OPTIONAL MODIFICATION

Action Labor cost Parts cost Cost per product 

Repair/preventive modification ...... 12 to 17 work-hours × $85 per 

hour = up to $1,445.

$90 to $913 .................................. Up to $2,358. 

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 proposed 

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 have 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 that the 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, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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.

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

98–22–10, Amendment 39–10858 (63 

FR 57240, October 27, 1998), and 

adding the following new AD:

that more restrictive maintenance 

requirements and airworthiness 

limitations are necessary. This proposed
