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 737–600, 

–700, –800, –900, and –900ER airplanes 

modified by particular supplemental 

type certificates (STC). This proposed 

AD was prompted by reports of cracks 

found during inspections of the in-flight 

entertainment system radome assembly. 

This proposed AD would require 

repetitive detailed inspections for cracks 

in the radome assembly, and 

replacement of the radome if necessary. 

We are proposing this AD to detect and 

correct cracks in the radome assembly, 

which could result in the radome (or 

pieces) separating from the airplane and 

striking the tail, and consequently 

reducing the controllability of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by September 19, 

2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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– 

2013–0670; Directorate Identifier 2013– 

NM–081–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 cracks in 26 

radomes. The cracks were found during 

inspections of the radome assembly of 

various Model 737 series airplanes that 

had in-flight entertainment systems 

installed using certain STC issued to 

Live TV. The STC numbers are STC 

ST00284BO, http://rgl.faa.gov/ 

Regulatory_and_Guidance_Library/ 

rgstc.nsf/0/ 

3ecc2e5e5f408bc1862579b30048ed60/ 

$FILE/ST00284BO.pdf; and STC 

ST02887AT, http://rgl.faa.gov/ 

Regulatory_and_Guidance_Library/ 

rgstc.nsf/0/ 

9bf85b85ea3e295d8625735600721055/ 

$FILE/ST02887AT.pdf. Investigation of 

the cause of the cracks revealed that 

lack of dimensional controls on the 

radome manufacturing drawings can 

result in the introduction of preload 

stress on the radome during its assembly 

with the skirt fairing. Preload stress 

combined with flight or handling stress, 

such as maintenance personnel stepping 

on the radome fairing assembly, might 

initiate a crack. The radome 

manufacturing drawings were revised 

on September 13, 2010, to add a control 

dimension, which was incorporated into 

production at radome serial number 

498. Cracks in the radome, if not 

corrected, could result in the radome (or 

pieces) separating from the airplane and 

striking the tail, and consequently 

reducing the controllability of the 

airplane. 

Relevant Service Information 

We reviewed Live TV Service Bulletin 

B737–53–0011, dated March 29, 2013. 

The service information describes 

procedures for repetitive inspections for 

cracks in the outer ply of the radome 

and replacing the radome if any crack is 

found. 

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 the Proposed AD 

and the Service Information.’’ In 


emcdonald on DSK67QTVN1PROD with PROPOSALS
47234 Federal Register / Vol. 78, No. 150 / Monday, August 5, 2013 / Proposed Rules 

addition, if any crack is found in a 

radome during an inspection, this 

proposed AD would require sending the 

inspection results to Live TV. 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directives Implementation Aviation 

Rulemaking Committee, to enhance the 

AD system. One enhancement was a 

new process for annotating which steps 

in the service information are required 

for compliance with an AD. 

Differentiating these steps from other 

tasks in the service information is 

expected to improve an owner’s/ 

operator’s understanding of crucial AD 

requirements and help provide 

consistent judgment in AD compliance. 

The actions specified in the service 

information described previously 

include steps that are labeled as RC 

(required for compliance) because these 

steps have a direct effect on detecting, 

preventing, resolving, or eliminating an 

identified unsafe condition. 

As noted in the specified service 

information, steps labeled as RC must be 

done to comply with the proposed AD. 

However, steps that are not labeled as 

RC are recommended. Those steps that 

are not labeled as RC may be deviated 

from, done as part of other actions, or 

done using accepted methods different 

from those identified in the service 

information without obtaining approval 

of an AMOC, provided the steps labeled 

as RC can be done and the airplane can 

be put back in a serviceable condition. 

Any substitutions or changes to steps 

labeled as RC will require approval of 

an alternative method of compliance. 

Differences Between the Proposed AD 

and the Service Information 

Live TV Service Bulletin B737–53– 

0011, dated March 29, 2013, 

recommends that the initial detailed 

inspection be done within 1,250 flight 

hours from 120 days following the 

release date of that service bulletin. We 

have determined that the compliance 

time should be within 1,250 flight hours 

after the effective date of this AD. This 

difference has been coordinated with 

Live TV. 

Costs of Compliance 

We estimate that this proposed AD 

affects 165 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 

Inspections ...................... 1 work-hour × $85 per hour = $85, per inspection 

cycle.

N/A ...... $85, per inspection cycle $14, 025, per inspection 

cycle. 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed inspections. We have no way 

of determining the number of aircraft 

that might need this replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement .................................... 8 work-hours × $85 per hour = $680 ........................................................ $23,000 $23,680 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591. ATTN: Information 

Collection Clearance Officer, AES–200. 

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.
