AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
BAE Systems (Operations) Limited
Model BAe 146 and Avro 146–RJ
airplanes. This AD requires repetitive
inspections of the wing top skin under
the rib 0 joint strap, and related
investigative and corrective actions if
necessary. This AD results from a report
of a significant crack in the wing top
skin under the rib 0 joint strap. We are
issuing this AD to detect and correct
corrosion and cracking in that area,
which could result in reduced structural
integrity of the wing.
DATES: This AD becomes effective
March 21, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of March 21, 2007.

You may examine the airworthiness
directive (AD) docket on the Internet at
https://dms.dot.gov or in person at the
Docket Management Facility office
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.
The Docket Management Facility office
(telephone (800) 647–5227) is located on
the plaza level of the Nassif Building at
the street address stated in the
ADDRESSES section.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain BAE Systems
(Operations) Limited Model BAe 146
and Avro 146–RJ airplanes. That NPRM
was published in the Federal Register
on July 3, 2006 (71 FR 37868). That
NPRM proposed to require repetitive
inspections of the wing top skin under
the rib 0 joint strap, and related
investigative and corrective actions if
necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the single comment
received.
Request for Posting of Service
Information
One commenter, the Modification and
Replacement Parts Association
(MARPA), requests that we revise our
procedures for incorporation by
reference (IBR) of service information in
ADs. MARPA states: ‘‘Typically
airworthiness directives are based upon
service information originating with the
type certificate holder or its suppliers.
Manufacturer service documents are
privately authored instruments
generally enjoying copyright protection
against duplication and distribution.
When a service document is
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
incorporated by reference pursuant to 5
U.S.C. 552(a) and 1 CFR part 51 into a
public document such as an
airworthiness directive, it loses its
private, protected status and becomes
itself a public document. If a service
document is used as a mandatory
element of compliance it should not
simply be referenced, but should be
incorporated into the regulatory
document. Public laws by definition
must be public which means they
cannot rely upon private writings.
‘‘Incorporated by reference service
documents should be made available to
the public by publication in the Docket
Management System (DMS) keyed to the
action that incorporates them. The
stated purpose of the Federal Register
incorporation by reference method is
brevity; to keep from expanding the
Federal Register needlessly by
publishing documents already in the
hands of the affected individuals.
Traditionally, ‘‘affected individuals’’
has meant aircraft owners and operators
who are generally provided service
information by the manufacturer.
However, a new class of affected
individuals has emerged since the
majority of aircraft maintenance is now
performed by specialty shops instead of
aircraft owners and operators. This new
class includes maintenance and repair
organizations (MRO), component
servicing and repair shops, parts
purveyors and distributors and
organizations manufacturing or
servicing alternatively certified parts
under 14 CFR 21.303 (PMA). Further,
the concept of brevity is now nearly
archaic as documents exist more
frequently in electronic format than on
paper.
‘‘We therefore request that the service
documents deemed essential to the
accomplishment of this proposed action
be (1) Incorporated by reference into the
regulatory instrument, and (2) published
in the DMS.’’
We acknowledge MARPA’s requests.
The Office of the Federal Register (OFR)
requires that documents that are
necessary to accomplish the
requirements of the AD be incorporated
by reference during the final rule phase
of rulemaking. This final rule
incorporates by reference the document
necessary for the accomplishment of the
requirements mandated by this AD.
Further, we point out that while
documents that are incorporated by
E:\FR\FM\14FER1.SGM
14FER1
6920
Federal Register / Vol. 72, No. 30 / Wednesday, February 14, 2007 / Rules and Regulations
reference do become public information,
they do not lose their copyright
protection. For that reason, we advise
the public to contact the manufacturer
to obtain copies of the referenced
service information.
In regard to MARPA’s request to post
service bulletins on the Department of
Transportation’s DMS, we are currently
in the process of reviewing issues
surrounding the posting of service
bulletins on the DMS as part of an AD
docket. Once we have thoroughly
examined all aspects of this issue and
have made a final determination, we
will consider whether our current
practice needs to be revised. No change
to the final rule is necessary in response
to this comment.
Conclusion
We have carefully reviewed the
available data, including the comment
received, and determined that air safety
and the public interest require adopting
the AD as proposed.

estimated costs for U.S. operators to
comply with this AD, per inspection

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.
rmajette on PROD1PC67 with RULES
We have determined that this AD will
not have federalism implications under
Executive Order 13132. This AD will
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 this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
(3) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
McDonnell Douglas Model DC–8–62,
DC–8–63, DC–8–62F, and DC–8–63F
airplanes. This AD requires revising the
wiring for the engine thrust brake circuit
and indicating circuit and other
specified actions, or rerouting the
wiring at plug P1–1762A on the
electrical power center generator control
panel, as necessary. This AD results
from the determination that the thrust
reverser systems on these airplanes do
not adequately preclude inadvertent
deployment of the thrust reversers. We
are issuing this AD to prevent
inadvertent deployment of the thrust
reversers during takeoff or landing,
which could result in loss of control of
the airplane.
DATES: This AD becomes effective
March 21, 2007.
The Director of the Federal Register

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain McDonnell Douglas
Model DC–8–62, DC–8–63, DC–8–62F,
and DC–8–63F airplanes. That NPRM
was published in the Federal Register
on October 19, 2006 (71 FR 61690). That
NPRM proposed to require revising the
wiring for the engine thrust brake circuit
and indicating circuit and other
specified actions, or rerouting the
wiring at plug P1–1762A on the
electrical power center generator control
panel, as necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
Costs of Compliance
There are about 70 airplanes of the
affected design in the worldwide fleet.
This AD affects about 45 airplanes of
U.S. registry. The required actions take
between 1 and 5 work hours per
airplane, depending on airplane
configuration, at an average labor rate of
$80 per work hour. For a certain
airplane configuration, required parts
cost about $9 per airplane. For a certain
other airplane configuration, required
parts cost about $2,825 per airplane.
Based on these figures, the estimated
cost of this AD for U.S. operators is
between $4,005 and $145,125, or
between $89 and $3,225 per airplane.

Request for Posting of Service Information
One commenter, the Modification and Replacement Parts Association
(MARPA), requests that we revise our procedures for incorporation by
reference (IBR) of service information in ADs. MARPA states:
``Typically airworthiness directives are based upon service information

In regard to MARPA's request to post service bulletins on the
Department of Transportation's DMS, we are currently in the process of

2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2007-04-04 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-14935. Docket No. FAA-
2006-25232; Directorate Identifier 2006-NM-106-AD.
Effective Date
(a) This AD becomes effective March 21, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (Operations) Limited Model
BAE 146-100A, -200A, and -300A series airplanes; and Avro 146-RJ70A,
146-RJ85A, and 146-RJ100A airplanes; certificated in any category;
as identified in BAE Systems (Operations) Limited Alert Inspection
Service Bulletin ISB.57-a071, dated April 12, 2006.
Unsafe Condition
(d) This AD results from a report of a significant crack in the
wing top skin under the rib 0 joint strap. We are issuing this AD to
detect and correct corrosion and cracking in that area, which could
result in reduced structural integrity of the wing.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspection
(f) Inspect the airplane at the applicable time specified in
paragraph 1.D. ``Compliance'' of BAE Systems (Operations) Limited
Alert Inspection Service Bulletin ISB.57-a071, dated April 12, 2006,
except, where the service bulletin specifies a compliance time after
the date on the service bulletin, this AD requires compliance within
the specified compliance time after the effective date of this AD.
The inspection required by this paragraph involves an ultrasonic
inspection for defects, including corrosion and cracking, of the
wing top skin under the rib 0 joint strap at the outer row of
fasteners, by doing all applicable actions specified in the
Accomplishment Instructions of the service bulletin. Do all
applicable related investigative and corrective actions before
further flight in accordance with the service bulletin, except as
required by paragraph (g) of this AD. Repeat the inspection at
intervals not to exceed 4,000 flight cycles or 24 months, whichever
occurs first.
Exceptions to Service Bulletin Specifications
(g) BAE Systems (Operations) Limited Alert Inspection Service
Bulletin ISB.57-a071, dated April 12, 2006, specifies two provisions
not specified in this AD.
(1) No inspection report is required by this AD.
[[Page 6921]]
(2) As an option, the service bulletin allows repairs specified
in an approved BAE Systems repair scheme. This AD instead requires
any repair using this option to be done in accordance with a method
approved by either the Manager, International Branch, ANM-116, FAA;
or the European Aviation Safety Agency (or its delegated agent).
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, International Branch, ANM-116, FAA, has the
authority to approve AMOCs for this AD, if requested in accordance
with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
