Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
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.

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, https://rgl.faa.gov/
Regulatory_and_Guidance_Library/
rgstc.nsf/0/
3ecc2e5e5f408bc1862579b30048ed60/
$FILE/ST00284BO.pdf; and STC
ST02887AT, https://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
E:\FR\FM\05AUP1.SGM
05AUP1
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:

Labor cost
Parts

Cost per product
Cost on U.S. operators
Inspections ......................
1 work-hour × $85 per hour = $85, per inspection

N/A ......

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

Paperwork Reduction Act
Authority for This Rulemaking
Regulatory Findings
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.
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.
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.

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:

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:

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.

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
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):

(e) Unsafe Condition
This AD was prompted by reports of cracks found during
inspections of the radome assembly. We are issuing this AD to detect
and correct cracks in the in-flight entertainment system 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Repetitive Inspections and Corrective Actions
Within 1,250 flight hours after the effective date of this AD:
Perform a detailed inspection for cracks of the radome assembly, in
accordance with the Accomplishment Instructions of Live TV Service
Bulletin B737-53-0011, dated March 29, 2013. Repeat the inspection
thereafter at intervals not to exceed 1,250 flight hours. If any
crack is found during any inspection required by this paragraph,
before further flight, replace the radome in accordance with the
Accomplishment Instructions of Live TV Service Bulletin B737-53-
0011, dated March 29, 2013.
(h) Reporting Requirement
If any crack is found during any inspection required by
paragraph (g) of this AD, submit a report of the findings to Live
TV, 8900 Hangar Boulevard, Orlando, FL 32827; telephone 407-812-
2600; fax 407-812-2526; email JaneAnne.Webb@livetv.net; at the
applicable time specified in paragraph (h)(1) or (h)(2) of this AD.
The report must include the information specified in the service
bulletin reporting form provided in Live TV Service Bulletin B737-
53-0011, dated March 29, 2013.
(1) If the inspection was accomplished on or after the effective
date of this AD: Submit the report within 30 days after the
inspection.
(2) If the inspection was accomplished before the effective date
of this AD: Submit the report within 30 days after the effective
date of this AD.
(i) Special Flight Permit
Special flight permits, as described in Section 21.197 and
Section 21.199 of the Federal Aviation Regulations (14 CFR 21.197
and 21.199), are not allowed.
(j) Paperwork Reduction Act Burden Statement
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a 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 OMB Control Number for this information collection is
2120-0056. Public reporting for this collection of information is
estimated to be approximately 5 minutes per response, including the
time for reviewing instructions, completing and reviewing the
collection of information. All responses to this collection of
information are 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.
(k) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Atlanta Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in the Related Information
section of this AD.
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
(3) If the service information contains steps that are labeled
as RC (Required for Compliance), those steps must be done to comply
with this AD; any 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 specified 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 require approval
of an AMOC.
