Airworthiness Directives; British
Aerospace Regional Aircraft Airplanes
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for British
Aerospace Regional Aircraft Model
HP.137 Jetstream Mk.1, Jetstream Series
200 and 3101, and Jetstream Model 3201
airplanes that would supersede AD 97–
10–05. This proposed AD results from
mandatory continuing airworthiness
information (MCAI) originated by an
aviation authority of another country to
identify and correct an unsafe condition
on an aviation product. The MCAI
describes the unsafe condition as cracks
in the main landing gear (MLG) fitting
at the pintle to cylinder interface, which
could cause failure of the MLG during
takeoff and landing. We are issuing this
proposed AD to require actions to
address the unsafe condition on these
products.
SUMMARY:
We must receive comments on
this proposed AD by June 12, 2017.

Discussion
On December 9, 1996, we issued AD
97–10–05, Amendment 39–10017 (62
FR 28318; May 23, 1997) (‘‘AD 97–10–
05’’). That AD required actions intended
to address an unsafe condition on
British Aerospace Regional Aircraft
Model HP.137 Jetstream Mk.1, Jetstream
Series 200 and 3101, and Jetstream
Model 3201 airplanes and was based on
mandatory continuing airworthiness
information (MCAI) originated by an
aviation authority of another country.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2017–
0053, dated March 24, 2017 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
Cracks were found during early fatigue
testing and in service on the main landing
gear (MLG) main fitting at the pintle to
cylinder interface.
This condition, if not detected and
corrected, could lead to structural failure of
the MLG, possibly resulting in loss of control
of the aeroplane during take-off or landing
runs.
To address this unsafe condition, BAE
Systems (Operations) Ltd published several
Service Bulletins (SB) which, in 1996, were
consolidated into a single SB 32–JA960142 to
provide instructions for inspection. CAA UK
issued AD 005–03–96 accordingly to require
repetitive inspections of the MLG.
Recently, a crack was found which was
below the critical crack length, but unusually
large compared to other similar cracks
E:\FR\FM\28APP1.SGM
28APP1
Federal Register / Vol. 82, No. 81 / Friday, April 28, 2017 / Proposed Rules
previously found in service. Further
investigation into the subject determined that
the existing inspection interval remains
valid, but also showed that the assumed
detectable defect size of 1.27 mm (0.05 in)
crack cannot be guaranteed using the current
accomplishment instructions for high
frequency eddy current (HFEC) or fluorescent
dye penetrant (FDP) inspection.
Consequently, BAE Systems (Operations)
Ltd issued SB 32–JA960142 Revision 04,
which provides improved procedures for
HFEC and FDP inspection to ensure the
detection of cracks of 1.27 mm (0.05 in).
For the reason described above, the [EASA]
AD retains the requirements of CAA UK AD
005–03–96, which is superseded, and
requires accomplishment of repetitive
inspections in accordance with the improved
procedures.

Related Service Information Under 1
CFR Part 51
We reviewed British Aerospace
Jetstream Series 3100 and 3200 Service
Bulletin 32–JA960142, Revision No. 4,
October 21, 2016, which describes
procedures for doing non-destructive
testing for cracks in the MLG and
corrective actions if cracks found exceed
a certain crack length. (The appendix to
the service bulletin specifically
describes fluorescent liquid penetrant
testing.) We reviewed Heroux Devtek
Service Bulletin 32–56, Revision 4,
dated August 16, 2016, which describes
procedures for doing a non-destructive
testing eddy current inspection for
cracks in the MLG. 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 of this NPRM.
FAA’s Determination and Requirements
of the 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 this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Costs of Compliance
We estimate that this proposed AD
will affect 26 products of U.S. registry.
We also estimate that it would take
about 6 work-hours per product to
VerDate Sep<11>2014
14:56 Apr 27, 2017
Jkt 241001
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $13,260, or $510 per
product.
In addition, we estimate that any
necessary follow-on actions would take
about 1 work-hour and require parts
costing $5,000, for a cost of $5,085 per
product. We have no way of
determining the number of products
that may need these actions.
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 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.

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.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by
removing Amendment 39–10017 (62 FR
28318; May 23, 1997), and adding the
following new AD:
■
British Aerospace Regional Aircraft: Docket
No. FAA–2017–0395; Directorate
Identifier 2017–CE–011–AD.
(a) Comments Due Date
We must receive comments by June 12,
2017.
(b) Affected ADs
This AD replaces AD 97–10–05;
Amendment 39–10017 (62 FR 28318; May 23,
1997) (‘‘AD 97–10–05’’).
(c) Applicability
This AD applies to British Aerospace
Regional Aircraft Model HP.137 Jetstream
Mk.1, Jetstream Series 200 and 3101, and
Jetstream Model 3201 airplanes, all serial
numbers, certificated in any category.
(d) Subject
Air Transport Association of America
(ATA) Code 32: Landing Gear.
(e) Reason
This AD was prompted by mandatory
continuing airworthiness information (MCAI)
originated by an aviation authority of another
country to identify and correct an unsafe
condition on an aviation product. The MCAI
describes the unsafe condition as cracks in
the main landing gear (MLG) fitting at the
pintle to cylinder interface, which could
cause failure of the MLG during takeoff and
landing. We are issuing this proposed AD to
detect and correct cracks in the main landing
gear (MLG), which could lead to structural
failure of the MLG and could result in loss
of control during takeoffs and landings.
(f) Actions and Compliance
Unless already done, do the following
actions listed in paragraphs (f)(1) through (3)
of this AD:
(1) Within the compliance times listed in
paragraph (f)(1)(i) or (ii) of this AD, as
applicable, inspect the MLG for cracks
following Appendix 1 of British Aerospace
Jetstream Series 3100 and 3200 Service
Bulletin 32–JA960142, Revision No. 4,

2016, as specified in British Aerospace
Jetstream Series 3100 and 3200 Service
Bulletin 32–JA960142, Revision No. 4,
October 21, 2016.
(i) For airplanes that have been inspected
following AD 97–10–05: Do the initial
inspection within 1,200 flight cycles (FC)
after the last inspection required by AD 97–
10–05 and repetitively thereafter at intervals
not to exceed 1,200 FC.
(ii) For airplanes that have not been
inspected following AD 97–10–05: Do the
initial inspection within 8,000 FC after
installation of the MLG or within the next
100 FC after the effective date of this AD,
whichever occurs later, and repetitively
thereafter at intervals not to exceed 1,200 FC.
(2) If any cracks are found during any of
the inspections required in paragraph (f)(1) of
this AD, before further flight, replace the
MLG with an airworthy part following British
Aerospace Jetstream Series 3100 and 3200
Service Bulletin 32–JA960142, Revision No.
4, October 21, 2016.
(3) The compliance times in paragraphs
(f)(1)(i) and (ii) of this AD are presented in
flight cycles (landings). If the total flight
cycles have not been kept, multiply the total
number of airplane hours time-in-service
(TIS) by 0.75 to calculate the cycles. For the
purposes of this AD:
(i) 100 hours TIS × .75 = 75 cycles; and
(ii) 1,000 hours TIS × .75 = 750 cycles.

Discussion
On December 9, 1996, we issued AD 97-10-05, Amendment 39-10017 (62
FR 28318; May 23, 1997) (``AD 97-10-05''). That AD required actions
intended to address an unsafe condition on British Aerospace Regional
Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101,
and Jetstream Model 3201 airplanes and was based on mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2017-0053, dated March 24, 2017 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
Cracks were found during early fatigue testing and in service on
the main landing gear (MLG) main fitting at the pintle to cylinder
interface.
This condition, if not detected and corrected, could lead to
structural failure of the MLG, possibly resulting in loss of control
of the aeroplane during take-off or landing runs.
To address this unsafe condition, BAE Systems (Operations) Ltd
published several Service Bulletins (SB) which, in 1996, were
consolidated into a single SB 32-JA960142 to provide instructions
for inspection. CAA UK issued AD 005-03-96 accordingly to require
repetitive inspections of the MLG.
Recently, a crack was found which was below the critical crack
length, but unusually large compared to other similar cracks
[[Page 19647]]
previously found in service. Further investigation into the subject
determined that the existing inspection interval remains valid, but
also showed that the assumed detectable defect size of 1.27 mm (0.05
in) crack cannot be guaranteed using the current accomplishment
instructions for high frequency eddy current (HFEC) or fluorescent
dye penetrant (FDP) inspection.
Consequently, BAE Systems (Operations) Ltd issued SB 32-JA960142
Revision 04, which provides improved procedures for HFEC and FDP
inspection to ensure the detection of cracks of 1.27 mm (0.05 in).
For the reason described above, the [EASA] AD retains the
requirements of CAA UK AD 005-03-96, which is superseded, and
requires accomplishment of repetitive inspections in accordance with
the improved procedures.

0395.
Related Service Information Under 1 CFR Part 51
We reviewed British Aerospace Jetstream Series 3100 and 3200
Service Bulletin 32-JA960142, Revision No. 4, October 21, 2016, which
describes procedures for doing non-destructive testing for cracks in
the MLG and corrective actions if cracks found exceed a certain crack
length. (The appendix to the service bulletin specifically describes
fluorescent liquid penetrant testing.) We reviewed Heroux Devtek
Service Bulletin 32-56, Revision 4, dated August 16, 2016, which
describes procedures for doing a non-destructive testing eddy current
inspection for cracks in the MLG. 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 of this NPRM.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Costs of Compliance
We estimate that this proposed AD will affect 26 products of U.S.
registry. We also estimate that it would take about 6 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $13,260, or $510 per product.
In addition, we estimate that any necessary follow-on actions would
take about 1 work-hour and require parts costing $5,000, for a cost of
$5,085 per product. We have no way of determining the number of
products that may need these actions.
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 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, 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
0
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]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-10017 (62 FR
28318; May 23, 1997), and adding the following new AD:
British Aerospace Regional Aircraft: Docket No. FAA-2017-0395;
Directorate Identifier 2017-CE-011-AD.
(a) Comments Due Date
We must receive comments by June 12, 2017.
(b) Affected ADs
This AD replaces AD 97-10-05; Amendment 39-10017 (62 FR 28318;
May 23, 1997) (``AD 97-10-05'').
(c) Applicability
This AD applies to British Aerospace Regional Aircraft Model
HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101, and Jetstream
Model 3201 airplanes, all serial numbers, certificated in any
category.
(d) Subject
Air Transport Association of America (ATA) Code 32: Landing
Gear.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as cracks in the
main landing gear (MLG) fitting at the pintle to cylinder interface,
which could cause failure of the MLG during takeoff and landing. We
are issuing this proposed AD to detect and correct cracks in the
main landing gear (MLG), which could lead to structural failure of
the MLG and could result in loss of control during takeoffs and
landings.
(f) Actions and Compliance
Unless already done, do the following actions listed in
paragraphs (f)(1) through (3) of this AD:
(1) Within the compliance times listed in paragraph (f)(1)(i) or
(ii) of this AD, as applicable, inspect the MLG for cracks following
Appendix 1 of British Aerospace Jetstream Series 3100 and 3200
Service Bulletin 32-JA960142, Revision No. 4, October 21, 2016; or
Heroux Devtek Service
[[Page 19648]]
Bulletin 32-56, Revision 4, dated August 16, 2016, as specified in
British Aerospace Jetstream Series 3100 and 3200 Service Bulletin
32-JA960142, Revision No. 4, October 21, 2016.
(i) For airplanes that have been inspected following AD 97-10-
05: Do the initial inspection within 1,200 flight cycles (FC) after
the last inspection required by AD 97-10-05 and repetitively
thereafter at intervals not to exceed 1,200 FC.
(ii) For airplanes that have not been inspected following AD 97-
10-05: Do the initial inspection within 8,000 FC after installation
of the MLG or within the next 100 FC after the effective date of
this AD, whichever occurs later, and repetitively thereafter at
intervals not to exceed 1,200 FC.
(2) If any cracks are found during any of the inspections
required in paragraph (f)(1) of this AD, before further flight,
replace the MLG with an airworthy part following British Aerospace
Jetstream Series 3100 and 3200 Service Bulletin 32-JA960142,
Revision No. 4, October 21, 2016.
(3) The compliance times in paragraphs (f)(1)(i) and (ii) of
this AD are presented in flight cycles (landings). If the total
flight cycles have not been kept, multiply the total number of
airplane hours time-in-service (TIS) by 0.75 to calculate the
cycles. For the purposes of this AD:
(i) 100 hours TIS x .75 = 75 cycles; and
(ii) 1,000 hours TIS x .75 = 750 cycles.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send

doug.rudolph@faa.gov. Before using any approved AMOC on any airplane
to which the AMOC applies, notify your appropriate principal
inspector (PI) in the FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
