Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2017–0187,
dated September 22, 2017 (referred to
after this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all BAE Systems (Operations)
Limited Model 4101 airplanes. The
MCAI states:
Maintenance instructions for BAE
Jetstream 4100 aeroplanes, which are
approved by EASA, are defined in BAE
Systems (Operations) Ltd Jetstream 4100
Service Bulletin (SB) J41–51–001, which
references certain Aircraft Maintenance
Manual (AMM) tasks. These instructions
have been identified as mandatory for
continued airworthiness.
Failure to accomplish these instructions
could result in an unsafe condition.
CAA UK [Civil Aviation Authority United
Kingdom] issued AD 005–02–2002 [which
corresponds to FAA AD 2005–15–11,
Amendment 39–14200 (70 FR 43025, July 26,
2005) (‘‘AD 2005–15–11’’)] to require
operators to comply with the inspection
instructions as referenced in SB J41–51–001
at original issue.
Since that [CAA UK] AD was issued, BAE
Systems (Operations) Ltd have determined
that the inspection requirements for a
number of maintenance tasks are incorrect.
Consequently, existing inspection items 52–
20–013, 53–10–006, 53–10–025, 53–10–029
and 53–10–079 will be amended in Chapter
05 of the AMM. Compliance periods for these
changes are given in BAE Systems
(Operations) Ltd SB J41–51–001 (now at
Revision 4) and BAE Systems (Operations)
Ltd Alert SB J41–A53–058. Those fatigue
inspections detailed in SB J41–51–001, at
PO 00000
Frm 00005
Fmt 4702
Sfmt 4702
Revision 3 or earlier, have now been
incorporated into Chapter 05 of the AMM. To
avoid duplication these tasks are deleted
from SB J41–51–001 at Revision 4.
For the reason described above, this
[EASA] AD retains the requirements of CAA
UK AD 005–02–2002, which is superseded,
and requires accomplishment of the actions
specified in BAE Systems (Operations) Ltd
Jetstream 4100 SB J41–51–001 Revision 4 and
Alert SB J41–A53–058 (hereafter collectively
referred to as ‘the SB’ in this [EASA] AD).
The actions include a one-time
detailed inspection of fuselage frame 90
for cracking or fatigue damage and
repair if necessary; and revising the
maintenance or inspection program, as
applicable, to incorporate new or
revised maintenance instructions and
airworthiness limitations. This
proposed AD was prompted by a
determination that it is possible for
cracks in fuselage frame 90 to exceed
the critical length for failure in less time
than the current inspection interval; and
a determination that inspection
requirements for a number of
maintenance tasks involving certain
airworthiness limitations are incorrect.
The unsafe condition is cracking in
fuselage frame 90, which could cause it
to fail and thereby compromise the
structural integrity of the aircraft
pressure hull; and fatigue damage of
various airplane structures, which could
result in reduced structural integrity of
the airplane.
You may examine the MCAI in the
AD docket on the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2018–
0511.
Relationship Between Proposed AD and
AD 2005–15–11
This NPRM would not supersede AD
2005–15–11. Rather, we have
determined that a stand-alone AD
would be more appropriate to address
the changes in the MCAI. This NPRM
would require a one-time detailed
inspection of fuselage frame 90 for
cracking or fatigue damage and revising
the maintenance or inspection program,
as applicable, to incorporate new or
revised maintenance instructions and
airworthiness limitations.
Accomplishment of the proposed
actions would then terminate all of the
requirements of AD 2005–15–11.
Related Service Information Under 1
CFR Part 51
BAE Systems (Operations) Limited
has issued the following service
information.
• Service Bulletin J41–51–001,

inspections and revisions to existing
inspection requirements and thresholds.
• Alert Service Bulletin J41–A53–058,
dated December 6, 2016. This service
information describes procedures for a
detailed inspection for cracking or
fatigue damage of fuselage frame 90.
This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
This AD requires revisions to certain
operator maintenance documents to
include new actions (e.g., inspections).
Compliance with these actions is
required by 14 CFR 91.403(c). For
airplanes that have been previously
modified, altered, or repaired in the
areas addressed by this proposed AD,
the operator may not be able to
accomplish the actions described in the
revisions. In this situation, to comply
with 14 CFR 91.403(c), the operator
must request approval for an alternative
method of compliance according to
paragraph (l)(1) of this proposed AD.
The request should include a
description of changes to the required
actions that will ensure the continued
damage tolerance of the affected
structure.
Differences Between This Proposed AD
and the MCAI or Service Information
The MCAI specifies that if there are
findings from the airworthiness
limitations section (ALS) inspection
tasks, corrective actions must be
accomplished in accordance with
Airbus maintenance documentation.
However, this proposed AD does not
include that requirement. Operators of
U.S.-registered airplanes are required by
general airworthiness and operational
regulations to perform maintenance
using methods that are acceptable to the
FAA. We consider those methods to be
adequate to address any corrective
actions necessitated by the findings of
ALS inspections required by this
proposed AD.
Costs of Compliance
We estimate that this proposed AD
affects 4 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Inspection ................................
2 work-hours × $85 per hour = $170 .....................................
daltland on DSKBBV9HB2PROD with PROPOSALS
We have determined that revising the
maintenance or inspection program
takes an average of 90 work-hours per
operator, although we recognize that
this number may vary from operator to
operator. In the past, we have estimated
that this action takes 1 work-hour per
airplane. Since operators incorporate
maintenance or inspection program
changes for their affected fleet(s), we
have determined that a per-operator
estimate is more accurate than a perairplane estimate. Therefore, we
estimate the total cost per operator to be
$7,650 (90 work-hours × $85 per workhour).
We have received no definitive data
that would enable us to provide cost
estimates for the on-condition actions
specified in 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
VerDate Sep<11>2014
16:14 Jun 13, 2018
Jkt 244001
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.
This proposed AD is issued in
accordance with authority delegated by
the Executive Director, Aircraft
Certification Service, as authorized by
FAA Order 8000.51C. In accordance
with that order, issuance of ADs is
normally a function of the Compliance
and Airworthiness Division, but during
this transition period, the Executive
Director has delegated the authority to
issue ADs applicable to transport
category airplanes to the Director of the
System Oversight Division.
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.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2017-0187, dated September 22, 2017 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all BAE Systems (Operations) Limited
Model 4101 airplanes. The MCAI states:
Maintenance instructions for BAE Jetstream 4100 aeroplanes,
which are approved by EASA, are defined in BAE Systems (Operations)
Ltd Jetstream 4100 Service Bulletin (SB) J41-51-001, which
references certain Aircraft Maintenance Manual (AMM) tasks. These
instructions have been identified as mandatory for continued
airworthiness.
Failure to accomplish these instructions could result in an
unsafe condition.
CAA UK [Civil Aviation Authority United Kingdom] issued AD 005-
02-2002 [which corresponds to FAA AD 2005-15-11, Amendment 39-14200
(70 FR 43025, July 26, 2005) (``AD 2005-15-11'')] to require
operators to comply with the inspection instructions as referenced
in SB J41-51-001 at original issue.
Since that [CAA UK] AD was issued, BAE Systems (Operations) Ltd
have determined that the inspection requirements for a number of
maintenance tasks are incorrect. Consequently, existing inspection
items 52-20-013, 53-10-006, 53-10-025, 53-10-029 and 53-10-079 will
be amended in Chapter 05 of the AMM. Compliance periods for these
changes are given in BAE Systems (Operations) Ltd SB J41-51-001 (now
at Revision 4) and BAE Systems (Operations) Ltd Alert SB J41-A53-
058. Those fatigue inspections detailed in SB J41-51-001, at
Revision 3 or earlier, have now been incorporated into Chapter 05 of
the AMM. To avoid duplication these tasks are deleted from SB J41-
51-001 at Revision 4.
For the reason described above, this [EASA] AD retains the
requirements of CAA UK AD 005-02-2002, which is superseded, and
requires accomplishment of the actions specified in BAE Systems
(Operations) Ltd Jetstream 4100 SB J41-51-001 Revision 4 and Alert
SB J41-A53-058 (hereafter collectively referred to as `the SB' in
this [EASA] AD).
The actions include a one-time detailed inspection of fuselage
frame 90 for cracking or fatigue damage and repair if necessary; and
revising the maintenance or inspection program, as applicable, to
incorporate new or revised maintenance instructions and airworthiness
limitations. This proposed AD was prompted by a determination that it
is possible for cracks in fuselage frame 90 to exceed the critical
length for failure in less time than the current inspection interval;
and a determination that inspection requirements for a number of
maintenance tasks involving certain airworthiness limitations are
incorrect. The unsafe condition is cracking in fuselage frame 90, which
could cause it to fail and thereby compromise the structural integrity
of the aircraft pressure hull; and fatigue damage of various airplane
structures, which could result in reduced structural integrity of the
airplane.
You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0511.
Relationship Between Proposed AD and AD 2005-15-11
This NPRM would not supersede AD 2005-15-11. Rather, we have
determined that a stand-alone AD would be more appropriate to address
the changes in the MCAI. This NPRM would require a one-time detailed
inspection of fuselage frame 90 for cracking or fatigue damage and
revising the maintenance or inspection program, as applicable, to
incorporate new or revised maintenance instructions and airworthiness
limitations. Accomplishment of the proposed actions would then
terminate all of the requirements of AD 2005-15-11.
Related Service Information Under 1 CFR Part 51
BAE Systems (Operations) Limited has issued the following service
information.
Service Bulletin J41-51-001, Revision 4, dated July 11,
2017. This service information describes new
[[Page 27723]]
inspections and revisions to existing inspection requirements and
thresholds.
Alert Service Bulletin J41-A53-058, dated December 6,
2016. This service information describes procedures for a detailed
inspection for cracking or fatigue damage of fuselage frame 90.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
This AD requires revisions to certain operator maintenance
documents to include new actions (e.g., inspections). Compliance with
these actions is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas addressed
by this proposed AD, the operator may not be able to accomplish the
actions described in the revisions. In this situation, to comply with
14 CFR 91.403(c), the operator must request approval for an alternative
method of compliance according to paragraph (l)(1) of this proposed AD.
The request should include a description of changes to the required
actions that will ensure the continued damage tolerance of the affected
structure.
Differences Between This Proposed AD and the MCAI or Service
Information
The MCAI specifies that if there are findings from the
airworthiness limitations section (ALS) inspection tasks, corrective
actions must be accomplished in accordance with Airbus maintenance
documentation. However, this proposed AD does not include that
requirement. Operators of U.S.-registered airplanes are required by
general airworthiness and operational regulations to perform
maintenance using methods that are acceptable to the FAA. We consider
those methods to be adequate to address any corrective actions
necessitated by the findings of ALS inspections required by this
proposed AD.
Costs of Compliance
We estimate that this proposed AD affects 4 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection......................... 2 work-hours x $85 per hour $0 $170 $680
= $170.
----------------------------------------------------------------------------------------------------------------
We have determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although we
recognize that this number may vary from operator to operator. In the
past, we have estimated that this action takes 1 work-hour per
airplane. Since operators incorporate maintenance or inspection program
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate.
Therefore, we estimate the total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in 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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes to the Director of the System Oversight
Division.
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.
