ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for all
BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146–
RJ airplanes. This proposed AD would
require calculating the current life of
each lift spoiler jack, and eventually
replacing each lift spoiler jack. This
proposed AD results from a review of all
system components as part of the lifeextension program for the affected
airplanes that indicated the fatigue life
limit of certain lift spoiler jacks cannot
be extended from the current life limit.
We are proposing this AD to prevent
failure of the lift spoiler jack, and
consequent increased drag and
uncommanded roll inputs, which could
reduce the flightcrew’s ability to control
the airplane.
DATES: We must receive comments on
this proposed AD by October 30, 2006.

Discussion
The European Aviation Safety Agency
(EASA), which is the airworthiness
authority for the European Union,
notified us that an unsafe condition may
exist on all BAE Systems (Operations)
Limited Model BAe 146 and Model
Avro 146–RJ airplanes. The EASA
advises that the life limit of the affected
airplanes ranges from 40,000 flight
cycles to 50,000 flight cycles, depending
E:\FR\FM\28SEP1.SGM
28SEP1
56904
Federal Register / Vol. 71, No. 188 / Thursday, September 28, 2006 / Proposed Rules
on the airplane variant. The
manufacturer has conducted a review of
all system components as part of a
program to extend the life limit beyond
40,000 to 50,000 flight cycles. This
program established that the fatigue life
of the lift spoiler jacks, part numbers (P/
Ns) P308–45–0002, P308–45–0102, and
P308–45–0202, cannot be extended
beyond the current life limit of 55,000
flight cycles for that part. Therefore, the
lift spoiler jacks must be replaced in
order for the life limit of the affected
airplanes to be extended. This
condition, if not corrected, could result
in failure of the lift spoiler jack, and
consequent increased drag and
uncommanded roll inputs, which could
reduce the flightcrew’s ability to control
the airplane.
Relevant Service Information
BAE Systems (Operations) Limited
has issued Modification Service Bulletin
ISB.27–178, dated January 14, 2005.
Modification Service Bulletin ISB.27–
178 describes procedures for calculating
the current life of each lift spoiler jack
with an affected P/N. Modification
Service Bulletin ISB.27–178 also
describes procedures for replacing each
P/N P308–45–0002 and –0102 lift
spoiler jack with a serviceable unit
before the part reaches its life limit. The
procedures for calculating the current
life depend on whether or not complete
component utilization records exist:
• If complete records exist, calculate
the life limits using those records.
• If complete records do not exist,
calculate the theoretical life in
conjunction with Appendix 2 of
Modification Service Bulletin ISB.27–
178.
Accomplishing the actions specified
in the service information is intended to
adequately address the unsafe
condition. The EASA mandated the
service information and issued EASA
airworthiness directive 2006–0138,
dated May 23, 2006, to ensure the
continued airworthiness of these
airplanes in the European Union.
Modification Service Bulletin ISB.27–
178 refers to the following:
• BAE Systems (Operations) Limited
Modification Service Bulletin SB.27–
179–70675A, dated January 19, 2005, as
an additional source of service
information for replacing lift spoiler
jacks having P/N P308–45–0002 and
–0102.
• BAE Systems (Operations) Limited
Inspection ISB.05–005, Revision 1,
dated June 9, 2005, as an additional
source of service information for
calculating the theoretical life when
complete utilization records do not
exist.
• Smiths Service Newsletter P308–
27–003, dated March 12, 2004, as an
additional source of service information
for resolving anomalies with the P/Ns.
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 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 EASA has
kept the FAA informed of the situation
described above. We have examined the
EASA’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
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD.

SUMMARY: The FAA is proposing a
Special Federal Aviation Regulation
(SFAR) applicable to the Mitsubishi
MU–2B series airplane that would
create new pilot training, experience,
and operating requirements. Following
an increased accident and incident rate
in the MU–2B series airplane, the FAA
conducted a safety evaluation of the
MU–2B series airplane and found that
changes in the training and operating
requirements for that airplane are
needed. These proposed regulations
would mandate additional operating
requirements and improve pilot training
for the MU–2B series airplane.

Discussion
The European Aviation Safety Agency (EASA), which is the
airworthiness authority for the European Union, notified us that an
unsafe condition may exist on all BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146-RJ airplanes. The EASA advises that
the life limit of the affected airplanes ranges from 40,000 flight
cycles to 50,000 flight cycles, depending
[[Page 56904]]
on the airplane variant. The manufacturer has conducted a review of all
system components as part of a program to extend the life limit beyond
40,000 to 50,000 flight cycles. This program established that the
fatigue life of the lift spoiler jacks, part numbers (P/Ns) P308-45-
0002, P308-45-0102, and P308-45-0202, cannot be extended beyond the
current life limit of 55,000 flight cycles for that part. Therefore,
the lift spoiler jacks must be replaced in order for the life limit of
the affected airplanes to be extended. This condition, if not
corrected, could result in failure of the lift spoiler jack, and
consequent increased drag and uncommanded roll inputs, which could
reduce the flightcrew's ability to control the airplane.
Relevant Service Information
BAE Systems (Operations) Limited has issued Modification Service
Bulletin ISB.27-178, dated January 14, 2005. Modification Service
Bulletin ISB.27-178 describes procedures for calculating the current
life of each lift spoiler jack with an affected P/N. Modification
Service Bulletin ISB.27-178 also describes procedures for replacing
each P/N P308-45-0002 and -0102 lift spoiler jack with a serviceable
unit before the part reaches its life limit. The procedures for
calculating the current life depend on whether or not complete
component utilization records exist:
If complete records exist, calculate the life limits using
those records.
If complete records do not exist, calculate the
theoretical life in conjunction with Appendix 2 of Modification Service
Bulletin ISB.27-178.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition. The EASA mandated
the service information and issued EASA airworthiness directive 2006-
0138, dated May 23, 2006, to ensure the continued airworthiness of
these airplanes in the European Union.
Modification Service Bulletin ISB.27-178 refers to the following:
BAE Systems (Operations) Limited Modification Service
Bulletin SB.27-179-70675A, dated January 19, 2005, as an additional
source of service information for replacing lift spoiler jacks having
P/N P308-45-0002 and -0102.
BAE Systems (Operations) Limited Inspection ISB.05-005,

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 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 EASA has kept the FAA
informed of the situation described above. We have examined the EASA'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
The following table 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 and placed it in the AD docket. 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:
[[Page 56905]]
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-2006-25920; Directorate
Identifier 2006-NM-137-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by October
30, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the airplanes specified in paragraphs
(c)(1) and (c)(2) of this AD, certificated in any category, having
lift spoiler jacks with part number (P/N) P308-45-0002, P308-45-
0102, or P308-45-0202.
(1) All BAE Systems (Operations) Limited Model BAe 146-100A, -
200A, and -300A series airplanes.
(2) All Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A
airplanes.
Unsafe Condition
(d) This AD results from a review of all system components as
part of the life-extension program for the affected airplanes that
indicated the fatigue life of certain lift spoiler jacks cannot be
extended from the current life limit. We are issuing this AD to
prevent failure of the lift spoiler jack, and consequent increased
drag and uncommanded roll inputs, which could reduce the
flightcrew's ability to control the airplane.
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.
Calculating the Life Limit
(f) Within 18 months after the effective date of this AD:
Calculate the current life of each lift spoiler jack in accordance
with the Accomplishment Instructions of BAE Systems (Operations)
Limited Modification Service Bulletin ISB.27-178, dated January 14,
2005.
Note 1: BAE Systems (Operations) Limited Modification Service
Bulletin ISB.27-178 refers to the service information listed in
Table 1 of this AD as additional sources of service information for
the actions in paragraphs (f) and (g) of this AD.
