BAE Systems (Operations) Limited
(Jetstream) Model 4101 airplanes. This
proposed AD would require the
overhaul of certain auxiliary
components installed on the main
landing gear (MLG) and nose landing
gear (NLG). This proposed AD is
prompted by manufacturer
determination that overhaul limits need
to be imposed for certain auxiliary
components of the MLG and NLG.
Components that exceed the established
overhaul limits could fail due to fatigue,
wear, and age. We are proposing this AD
to prevent failure of the MLG or NLG,
and consequent damage to the airplane
and injury to flightcrew and passengers.

Discussion
The Civil Aviation Authority (CAA),
which is the airworthiness authority for
the United Kingdom, notified us that an
unsafe condition may exist on all BAE
Systems (Operations) Limited
(Jetstream) Model 4101 airplanes. The
CAA received a report of manufacturer
determination that overhaul limits need
to be imposed for certain auxiliary
components of the MLG and NLG.
Components that exceed the established
overhaul limits could fail due to fatigue,
wear, and age. This condition, if not
corrected, could result in failure of the
MLG or NLG, and consequent damage to
the airplane and injury to flightcrew and
passengers.
Relevant Service Information
BAE Systems (Operations) Limited
has issued Service Bulletin J41–32–081,
dated August 6, 2002. The service
bulletin describes procedures for the
overhaul of certain auxiliary
components installed on the MLG and
NLG. Auxiliary components are the
MLG shock struts, the NLG shock strut,
the MLG retract actuators, the NLG
retract actuator, the MLG drag braces/
actuators, the MLG uplocks/actuators,
the NLG downlock/actuator, the NLG
uplock/actuator, and the steering
selector valve.
Service Bulletin J41–32–081 refers to
BAE Systems (Operations) Limited
Service Bulletin J41–05–001, Revision 2,
dated March 15, 2002, as an additional
source of service information for
calculating estimated usage of affected
auxiliary components.
The CAA mandated the service
information and issued British
airworthiness directive 006–08–2002 to
ensure the continued airworthiness of
these airplanes in the United Kingdom.
FAA’s Determination and Requirements
of the Proposed AD
This airplane model is manufactured
in the United Kingdom and is type
certificated for operation in the United
States under the provisions of section
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 products of this
type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD,
which would require the overhaul of
certain auxiliary components installed
on the MLG and NLG, except as
discussed under ‘‘Differences Between
the Proposed AD and Referenced
Service Bulletin.’’
Differences Between the Proposed AD
and Referenced Service Bulletin
BAE Systems (Operations) Limited
Service Bulletin J42–32–081 describes
procedures for notifying the
manufacturer of the accomplishment of
the service bulletin; however, this
proposed AD would not require this
notification.
BAE Systems (Operations) Limited
Service Bulletin J42–32–081 specifies
that certain affected components must
be overhauled on or before July 31,
2004; however, this proposed AD would
specify that certain affected components
must be overhauled within 18 months
after the effective date of this proposed
AD. In developing an appropriate
compliance time for this AD, we
considered the manufacturer’s
recommendation, the degree of urgency
associated with the subject unsafe
condition and the average utilization of
the affected fleet. In light of all of these
factors, we find that a compliance time
of 18 months represents an appropriate
interval of time for affected airplanes to
continue to operate without
compromising safety. This compliance
time has been coordinated with the
CAA.
Costs of Compliance
This proposed AD would affect about
57 airplanes of U.S. registry. The
following table, using an average labor
rate of $65 per hour, provides the
estimated costs for U.S. operators to
comply with this proposed AD.

Federal Register / Vol. 70, No. 65 / Wednesday, April 6, 2005 / Proposed Rules
Authority: 49 U.S.C. 106(g), 40113, 44701.
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. See the ADDRESSES
section for a location to examine the
regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, 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

AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for all
Fokker Model F.28 Mark 0100 series
airplanes. This proposed AD would
require an inspection to determine the
part number of the passenger service
unit (PSU) panels for the PSU
modification status, and corrective
actions if applicable. This proposed AD
is prompted by reported incidents of
smoke in the passenger compartment
during flight. One of those incidents
also included a burning smell and
consequently led to emergency
evacuation of the airplane. We are
proposing this AD to prevent
overheating of the PSU panel due to
moisture ingress, which could result in
smoke or fire in the passenger cabin.
DATES: We must receive comments on
this proposed AD by May 6, 2005.

Discussion
The Civil Aviation Authority (CAA), which is the airworthiness
authority for the United Kingdom, notified us that an unsafe condition
may exist on all BAE Systems (Operations) Limited (Jetstream) Model
4101 airplanes. The CAA received a report of manufacturer determination
that overhaul limits need to be imposed for certain auxiliary
components of the MLG and NLG. Components that exceed the established
overhaul limits could fail due to fatigue, wear, and age. This
condition, if not corrected, could result in failure of the MLG or NLG,
and consequent damage to the airplane and injury to flightcrew and
passengers.
Relevant Service Information
BAE Systems (Operations) Limited has issued Service Bulletin J41-
32-081, dated August 6, 2002. The service bulletin describes procedures
for the overhaul of certain auxiliary components installed on the MLG
and NLG. Auxiliary components are the MLG shock struts, the NLG shock
strut, the MLG retract actuators, the NLG retract actuator, the MLG
drag braces/actuators, the MLG uplocks/actuators, the NLG downlock/
actuator, the NLG uplock/actuator, and the steering selector valve.
Service Bulletin J41-32-081 refers to BAE Systems (Operations)
Limited Service Bulletin J41-05-001, Revision 2, dated March 15, 2002,
as an additional source of service information for calculating
estimated usage of affected auxiliary components.
The CAA mandated the service information and issued British
airworthiness directive 006-08-2002 to ensure the continued
airworthiness of these airplanes in the United Kingdom.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in the United Kingdom and is
type certificated for operation in the United States under the
provisions of section 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 products of this type design that are
certificated for operation in the United States.
Therefore, we are proposing this AD, which would require the
overhaul of certain auxiliary components installed on the MLG and NLG,
except as discussed under ``Differences Between the Proposed AD and
Referenced Service Bulletin.''
Differences Between the Proposed AD and Referenced Service Bulletin
BAE Systems (Operations) Limited Service Bulletin J42-32-081
describes procedures for notifying the manufacturer of the
accomplishment of the service bulletin; however, this proposed AD would
not require this notification.
BAE Systems (Operations) Limited Service Bulletin J42-32-081
specifies that certain affected components must be overhauled on or
before July 31, 2004; however, this proposed AD would specify that
certain affected components must be overhauled within 18 months after
the effective date of this proposed AD. In developing an appropriate
compliance time for this AD, we considered the manufacturer's
recommendation, the degree of urgency associated with the subject
unsafe condition and the average utilization of the affected fleet. In
light of all of these factors, we find that a compliance time of 18
months represents an appropriate interval of time for affected
airplanes to continue to operate without compromising safety. This
compliance time has been coordinated with the CAA.
Costs of Compliance
This proposed AD would affect about 57 airplanes of U.S. registry.
The following table, using an average labor rate of $65 per hour,
provides the estimated costs for U.S. operators to comply with 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 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. See the ADDRESSES section for a location
to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, 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
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 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-2005-20865; Directorate
Identifier 2003-NM-103-AD.
Comments Due Date
(a) The Federal Aviation Administration must receive comments on
this AD action by May 6, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all BAE Systems (Operations) Limited
(Formerly British Aerospace Regional Aircraft) Model Jetstream 4101
airplanes, certificated in any category.
Unsafe Condition
(d) This AD was prompted by manufacturer determination that
overhaul limits need to be imposed for certain auxiliary components
of the MLG and NLG. Components that exceed the established overhaul
limits could fail due to fatigue, wear, and age. We are issuing this
AD to prevent failure of the MLG or NLG, and consequent damage to
the airplane and injury to flightcrew and passengers.
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.
Overhaul of Landing Gear
(f) Within 18 months after the effective date of this AD,
overhaul auxiliary components installed on the MLG and NLG in
accordance with the Accomplishment Instructions of BAE Systems
(Operations) Limited Service Bulletin J41-32-081, dated August 6,
2002, except as provided by paragraph (g) of this AD; and thereafter
as specified in the ``Overhaul Period'' column of Table 1 of the
Accomplishment Instructions of the service bulletin.
Note 1: BAE Systems (Operations) Limited Service Bulletin J41-
32-081 refers to BAE Systems (Operations) Limited Service Bulletin
J41-05-001, Revision 2, dated March 15, 2002, as an additional
source of service information for calculating estimated usage of
affected auxiliary components.
No Reporting Requirement
(g) Although the service bulletin referenced in this AD
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
Alternative Methods of Compliance (AMOCs)
(h) The Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA, has the authority to approve AMOCs for
this AD, if requested in accordance with the procedures found in 14
CFR 39.19.
Related Information
(i) British airworthiness directive 006-08-2002 also addresses
the subject of this AD.
Issued in Renton, Washington, on March 30, 2005.
