Discussion
The Civil Aviation Authority (CAA),
which is the airworthiness authority for
the United Kingdom, notified us that an
unsafe condition may exist on certain
BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146–
RJ airplanes. The CAA advises of inservice reports of hinge bracket failures
on the main landing gear (MLG) doors.
The failures were caused by stress
corrosion of the bearing housing of the
hinge bracket, which was accelerated by
the subsequent expansion of existing
corrosion. This condition, if not
corrected, could result in separation of
the door, consequent structural damage,
and possible injury to people on the
ground.
Relevant Service Information
BAE Systems (Operations) Limited
has issued Inspection Service Bulletin
ISB.52–113, Revision 1, dated February
11, 2005. The ISB describes procedures
for a one-time detailed inspection for
corrosion of the hinge bracket assembly
of the left and right MLG doors, and
corrective action if necessary. The
corrective action for corrosion involves
replacement of the hinge bracket
assembly with a new assembly and
application of protective treatment; the
corrective action for light corrosion
involves removing the corrosion and
applying protective treatment. If no
corrosion is found, the service bulletin
VerDate Aug<31>2005
16:23 Jan 03, 2006
Jkt 208001
describes procedures for applying
protective treatment. Accomplishing the
actions specified in the service
information is intended to adequately
address the unsafe condition. The CAA
mandated the service information and
issued British airworthiness directive
G–2005–0017, dated July 6, 2005, to
ensure the continued airworthiness of
these airplanes in the United Kingdom.
FAA’s Determination and Requirements
of the Proposed AD
These airplane models are
manufactured in the United Kingdom
and are type certificated for operation in
the United States under the provisions
of § 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement. Pursuant to this bilateral
airworthiness agreement, the CAA has
kept the FAA informed of the situation
described above. We have examined the
CAA’s findings, evaluated all pertinent
information, and determined that we
need to issue an AD for airplanes of this
type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD,
which would require accomplishing the
actions specified in the service
information described previously.
Costs of Compliance
This proposed AD would affect about
35 airplanes of U.S. registry. The
proposed actions would take about 4
work hours per airplane, at an average
labor rate of $65 per work hour. Based
on these figures, the estimated cost of
the proposed actions for U.S. operators
is $9,100, or $260 per airplane.
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 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); and
3. 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.

stack of the flight deck humidifier with
a supplier-tested cell stack, or replacing
the cell stack with a blanking plate and
subsequently deactivating the flight
deck humidifier, if necessary. For other
airplanes, that proposed AD would have
required replacing the cell stack with a
supplier-tested cell stack, or replacing
the cell stack with a blanking plate and
subsequently deactivating the
humidifier system, if necessary. The
proposed AD also would have allowed
blanking plates to be replaced with cell
stacks. This new action revises the
proposed rule by adding airplanes to the
applicability, requiring an inspection of
the flight deck humidifier to determine
certain part numbers on certain
airplanes, and requiring replacement of
the cell stack on certain other airplanes.
The actions specified by this new
proposed AD are intended to prevent an
increased pressure drop across the
humidifier and consequent reduced
airflow to the flight deck, which could
result in the inability to clear any smoke
that might appear in the flight deck.
This action is intended to address the
identified unsafe condition.

Discussion
The Civil Aviation Authority (CAA), which is the airworthiness
authority for the United Kingdom, notified us that an unsafe condition
may exist on certain BAE Systems (Operations) Limited Model BAe 146 and
Model Avro 146-RJ airplanes. The CAA advises of in-service reports of
hinge bracket failures on the main landing gear (MLG) doors. The
failures were caused by stress corrosion of the bearing housing of the
hinge bracket, which was accelerated by the subsequent expansion of
existing corrosion. This condition, if not corrected, could result in
separation of the door, consequent structural damage, and possible
injury to people on the ground.
Relevant Service Information
BAE Systems (Operations) Limited has issued Inspection Service
Bulletin ISB.52-113, Revision 1, dated February 11, 2005. The ISB
describes procedures for a one-time detailed inspection for corrosion
of the hinge bracket assembly of the left and right MLG doors, and
corrective action if necessary. The corrective action for corrosion
involves replacement of the hinge bracket assembly with a new assembly
and application of protective treatment; the corrective action for
light corrosion involves removing the corrosion and applying protective
treatment. If no corrosion is found, the service bulletin describes
procedures for applying protective treatment. Accomplishing the actions
specified in the service information is intended to adequately address
the unsafe condition. The CAA mandated the service information and
issued British airworthiness directive G-2005-0017, dated July 6, 2005,
to ensure the continued airworthiness of these airplanes in the United
Kingdom.
FAA's Determination and Requirements of the Proposed AD
These airplane models are manufactured in the United Kingdom and
are type certificated for operation in the United States under the
provisions of Sec. 21.29 of the Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral airworthiness agreement. Pursuant
to this bilateral airworthiness agreement, the CAA has kept the FAA
informed of the situation described above. We have examined the CAA's
findings, evaluated all pertinent information, and determined that we
need to issue an AD for airplanes of this type design that are
certificated for operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
This proposed AD would affect about 35 airplanes of U.S. registry.
The proposed actions would take about 4 work hours per airplane, at an
average labor rate of $65 per work hour. Based on these figures, the
estimated cost of the proposed actions for U.S. operators is $9,100, or
$260 per airplane.
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 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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.

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.
Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
BAE Systems (Operations) Limited (Formerly British Aerospace
Regional Aircraft): Docket No. FAA-2005-23477; Directorate
Identifier 2005-NM-181-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by February
3, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (Operations) Limited Model
BAe 146-100A, -200A, and -300A series airplanes, and Model Avro 146-
RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any
category; as identified in BAE Systems
[[Page 299]]
(Operations) Limited Inspection Service Bulletin ISB.52-113,
Revision 1, dated February 11, 2005.
Unsafe Condition
(d) This AD results from in-service reports of hinge bracket
failures on the main landing gear (MLG) doors. We are issuing this
AD to prevent failure of the hinge bracket on the MLG door, which
could result in separation of the door, consequent structural damage
to the airplane, and possible injury to people on the ground.
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/Corrective Action
(f) At the applicable time specified in paragraph (f)(1) or
(f)(2) of this AD: Perform a one-time detailed inspection for
corrosion of the hinge bracket assembly of the left and right MLG
doors by doing all the applicable actions in accordance with the
Accomplishment Instructions of BAE Systems (Operations) Limited
Inspection Service Bulletin ISB.52-113, Revision 1, dated February
11, 2005. Perform any applicable corrective action before further
flight in accordance with the service bulletin. If no corrosion is
found, before further flight, apply protective treatment in
accordance with the service bulletin.
(1) For airplanes on which the date of issuance of the original
standard airworthiness certificate or the date of issuance of the
original export certificate of airworthiness is on or before
February 28, 1991: Within 192 months since the date of issuance of
the original standard airworthiness certificate or the date of
issuance of the original export certificate of airworthiness, or
within 12 months after the effective date of this AD, whichever is
later.
(2) For airplanes on which the date of issuance of the original
standard airworthiness certificate or the date of issuance of the
original export certificate of airworthiness is after February 28,
1991: Within 24 months after the effective date of this AD.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
Inspections Accomplished According to Previous Issue of Service
Bulletin
(g) Inspections accomplished before the effective date of this
AD according to BAE Systems (Operations) Limited Inspection Service
Bulletin ISB.52-113, dated February 2, 2001, are considered
acceptable for compliance with the corresponding action specified in
this AD.
Parts Installation
(h) As of the effective date of this AD, no person may install,
on any airplane, a hinge bracket assembly of the left and right MLG
doors, unless it has been inspected (and any corrective actions
done) according to BAE Systems (Operations) Limited Inspection
Service Bulletin ISB.52-113, Revision 1, dated February 11, 2005.
No Reporting Required
(i) Although BAE Systems (Operations) Limited Inspection Service
Bulletin ISB.52-113, Revision 1, dated February 11, 2005, referenced
in this AD, specifies to submit certain information to the
manufacturer, this AD does not include that requirement.
