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 a report of an approximate 

8-inch crack found in the fuselage skin 

under the aft drain mast. This proposed 

AD would require a detailed inspection 

for cracking and corrosion of the 

channel and fillers adjacent to the drain 

mast bolts, an inspection to determine 

the location of the bonding strap, a 

measurement of the washers under the 

drain mast bolts, and related 

investigative actions and repair if 

necessary. We are proposing this AD to 

detect and correct cracking in the 

fuselage skin and internal support 

structure, which could result in 

uncontrolled decompression of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by October 5, 2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

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– 

2012–0857; Directorate Identifier 2011– 

NM–244–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 a report of an aft drain 

mast found loose on a Model 737–400 

series airplane with approximately 

30,500 total flight cycles. Further 

investigation revealed the fuselage skin 

and surrounding back-up structure were 

cracked. An 8-inch crack common to the 

fuselage skin was hidden under the 

drain mast. The crack was likely caused 

by incorrect installation of the drain 

mast. A drain mast that is not installed 

correctly can cause cracks in the 

fuselage skin and the internal support 

structure. The skin cracks cannot be 

seen because they are hidden by the 

drain mast. This condition, if not 

corrected, could result in uncontrolled 

decompression of the airplane. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 737–53A1318, dated October 

31, 2011. 

For airplanes identified as Group 1 in 

Boeing Alert Service Bulletin 737– 

53A1318, dated October 31, 2011, this 

service bulletin describes procedures for 

doing a detailed inspection for cracking 

and corrosion of the channel and fillers 

adjacent to the drain mast bolts, an 

inspection to determine the location of 

the bonding strap, a measurement of the 

washers under the drain mast bolts, and 

related investigative actions and repair 

if necessary. Related investigative 

actions include removing the drain mast 

and doing a high frequency eddy 

current (HFEC) and detailed inspection 

for cracking and corrosion of the skin, 

channel, and fillers. This service 

bulletin also specifies contacting Boeing 

for repair instructions and doing the 

repair. 

For airplanes identified as Group 2 in 

Boeing Alert Service Bulletin 737– 

53A1318, dated October 31, 2011, this 

service bulletin specifies contacting 

Boeing for inspection and repair 

instructions and doing the actions. 

The compliance time for the 

inspection is within 120 days, and 

before further flight for the repair. 

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and the Service Information.’’ 

Differences Between the Proposed AD 

and the Service Information 

Boeing Alert Service Bulletin 737– 

53A1318, dated October 31, 2011, 

specifies to contact the manufacturer for 

instructions on how to inspect and 

repair certain conditions, but this 

proposed AD would require that those 

actions be accomplished 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 612 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 

Detailed inspection, bonding strap inspection, washer 

measurement.

4 work-hours × $85 per hour = $340 $0 $340 $208,080 

We estimate the following costs to do 

certain necessary conditional actions 

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 actions: 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1

We have received no definitive data 

that would enable us to provide a cost 

estimate for the repair 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, 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.

coordinates of the airport and 

navigation aids would be adjusted in the 

respective Class D and Class E airspace 

areas. The comment period closed July 

19, 2012. The FAA received one 

comment from the National Business 

Aviation Association (NBAA). 

The NBAA recommended making the 

Class E airspace area extending upward 

from 1,200 feet above the surface larger 

by lowering some of the adjacent Class 

E airspace, which begins from between 

10,000 Mean Sea Level (MSL) and 

14,500 MSL, for aircraft safety. The FAA 

found merit in this comment, and, 

therefore, proposes the additional Class 

E airspace area, extending upward from 

1,200 feet above the surface, be made 

larger. The FAA seeks comments on this 

SNPRM.
