ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 the in-service special detailed inspection technique required for the Jetstream 3200’s life extension program was delayed; consequently, the in-service special detailed inspection technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this AD to require actions to address the unsafe condition on these products. SUMMARY: This AD is effective September 21, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of September 21, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to adding an AD that would apply to British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. The NPRM was published in the Federal Register on May 26, 2015 (80 FR 29988). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: The Jetstream 3200 Life Extension Programme (LEP) permits the airframe life limit to be extended from 45 000 flight cycles (FC) to 67 000 FC. Entry into the LEP requires operators to accomplish inspections specified in the Jetstream 3200 Supplemental Structural Inspections Document (SSID). SSID task 57–10–227 is the inspection requirement for the wing main spar at Rib 36. The threshold for task 57–10–227 is 48 000 FC, with a repeat interval of 16 800 FC, using a Special Detailed Inspection (SDI). Development of the in-service SDI technique required for SSID task 57–10–227 was delayed by BAE Systems (Operations) Ltd, as a result of which it is not formally part of the LEP and may therefore not be accomplished as intended. This condition, if not corrected, could lead to cracks in the wing main spar remaining undetected, possibly resulting in failure of the wing and loss of the aeroplane. To address this potential unsafe condition, BAE Systems (Operations) Ltd issued SB 57– JA140140 to provide SDI instructions for the wing main spar at Rib 36, which includes a reduced repeat inspection interval. For the reasons described above, this AD requires repetitive inspections of the wing main spar around Rib 36 to detect cracks and, depending on findings, accomplishment of the applicable corrective action(s). The SSID will be revised in due course to include the SDI. The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/ PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 #!documentDetail;D=FAA-2015-17440002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 29988, May 26, 2015) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 29988, May 26, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 29988, May 26, 2015). Related Service Information Under 1 CFR Part 51 We reviewed British Aerospace Regional Aircraft British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57–JA140140, Original Issue, dated: June 26, 2014. The service information describes procedures for inspections of the wing main spar around Rib 36 to detect cracks and, depending on findings, accomplishment of the applicable corrective action(s). 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 AD. Costs of Compliance We estimate that this AD will affect 22 products of U.S. registry. We also estimate that it will take about 96 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the AD on U.S. operators to be $179,520, or $8,160 per product. We have no way of determining any necessary follow-on actions, costs, or the number of products that may need these actions. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid E:\FR\FM\17AUR1.SGM 17AUR1 Federal Register / Vol. 80, No. 158 / Monday, August 17, 2015 / Rules and Regulations OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES–200. 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. tkelley on DSK3SPTVN1PROD with RULES Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 AD: (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 FAA amends § 39.13 by adding the following new AD: ■ 2015–16–06 British Aerospace Regional Aircraft: Amendment 39–18231; Docket No. FAA–2015–1744; Directorate Identifier 2015–CE–016–AD. (a) Effective Date This airworthiness directive (AD) becomes effective September 21, 2015. (b) Affected ADs None. (c) Applicability This AD applies to British Aerospace Regional Aircraft Jetstream Model 3201 airplanes, all serial numbers, that are: (1) Certificated in any category; and (2) Modified in service following BAE Systems (Operations) Ltd Service Bulletin (SB) 05- JM8229. (d) Subject Air Transport Association of America (ATA) Code 57: Wings. (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 the inservice special detailed inspection technique required for the Jetstream 3200’s life PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 49131 extension program was delayed; consequently, the in-service special detailed inspection (SDI) technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this AD to detect and correct cracking in the wing main spar, which could result in structural failure of the wing with consequent loss of control. (f) Actions and Compliance Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD: (1) Before accumulating a total of 53,950 flight cycles (FC) on the airplane or within the next 50 FC after September 21, 2015 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 14,300 FC, accomplish an eddy current (EC) and an x-ray inspection of the wing main spar around rib 36 following the instructions of British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57– JA140140, Original Issue, dated June 26, 2014. For the purposes of this AD, owner/ operators who do not track total FC must multiply the total number of airplane hours time-in-service (TIS) by 0.75 to calculate the cycles. (2) If any crack or corrosion is found during any inspection required by paragraph (f)(1) of this AD, before further flight, contact BAE Systems (Operations) Ltd for FAAapproved repair instructions approved specifically for this AD and accomplish those instructions. You can find contact information for BAE Systems (Operations) Ltd in paragraph (i)(3) of this AD.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to adding an AD that would apply to British Aerospace Regional Aircraft Model Jetstream Series 3101 and Jetstream Model 3201 airplanes. The NPRM was published in the Federal Register on June 9, 2015 (80 FR 32510). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: The review of the BAE production drawing for main landing gear (MLG) fitting installation identified a risk of omitting installation of a countersunk washer under the head of the MLG trunnion cap tension bolts, potentially causing fatigue in the bolt shank under the head of such tension bolt(s). This condition, if not detected and corrected, could lead to failure of the bolt(s), thereby compromising the structural integrity of the other MLG tension bolts holding the MLG in place, possibly resulting in collapse of the MLG on take-off or landing with consequent damage to the aeroplane and injury to occupants. Although so far, no in-service bolt head failures have been reported since entry in to service of the type design in 1986, to address this potential unsafe condition, BAE Systems (Operations) Ltd issued Service Bulletin (SB) 57–JA120141 to provide inspection instructions. For the reasons described above, this AD requires inspection and, depending on findings, replacement of the MLG trunnion cap tension bolts.

Airworthiness Directives; British Aerospace Regional Aircraft 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for British 
Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This 
AD results from mandatory continuing airworthiness information (MCAI) 
issued 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 the in-service special detailed inspection 
technique required for the Jetstream 3200's life extension program was 
delayed; consequently, the in-service special detailed inspection 
technique is not formally part of the life extension program and may 
therefore not be accomplished as intended. We are issuing this AD to 
require actions to address the unsafe condition on these products.

DATES: This AD is effective September 21, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of September 21, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to adding an AD that would apply to British Aerospace Regional 
Aircraft Model Jetstream Model 3201 airplanes. The NPRM was published 
in the Federal Register on May 26, 2015 (80 FR 29988). The NPRM 
proposed to correct an unsafe condition for the specified products and 
was based on mandatory continuing airworthiness information (MCAI) 
originated by an aviation authority of another country. The MCAI 
states:

    The Jetstream 3200 Life Extension Programme (LEP) permits the 
airframe life limit to be extended from 45 000 flight cycles (FC) to 
67 000 FC. Entry into the LEP requires operators to accomplish 
inspections specified in the Jetstream 3200 Supplemental Structural 
Inspections Document (SSID). SSID task 57-10-227 is the inspection 
requirement for the wing main spar at Rib 36. The threshold for task 
57-10-227 is 48 000 FC, with a repeat interval of 16 800 FC, using a 
Special Detailed Inspection (SDI). Development of the in-service SDI 
technique required for SSID task 57-10-227 was delayed by BAE 
Systems (Operations) Ltd, as a result of which it is not formally 
part of the LEP and may therefore not be accomplished as intended.
    This condition, if not corrected, could lead to cracks in the 
wing main spar remaining undetected, possibly resulting in failure 
of the wing and loss of the aeroplane.
    To address this potential unsafe condition, BAE Systems 
(Operations) Ltd issued SB 57-JA140140 to provide SDI instructions 
for the wing main spar at Rib 36, which includes a reduced repeat 
inspection interval.
    For the reasons described above, this AD requires repetitive 
inspections of the wing main spar around Rib 36 to detect cracks 
and, depending on findings, accomplishment of the applicable 
corrective action(s).

    The SSID will be revised in due course to include the SDI. The MCAI 
can be found in the AD docket on the Internet at: https://www.regulations.gov/#!documentDetail;D=FAA-2015-1744-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 29988, May 26, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 29988, May 26, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 29988, May 26, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed British Aerospace Regional Aircraft British Aerospace 
Jetstream Series 3100 & 3200 Service Bulletin 57-JA140140, Original 
Issue, dated: June 26, 2014. The service information describes 
procedures for inspections of the wing main spar around Rib 36 to 
detect cracks and, depending on findings, accomplishment of the 
applicable corrective action(s). 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 AD.

Costs of Compliance

    We estimate that this AD will affect 22 products of U.S. registry. 
We also estimate that it will take about 96 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $179,520, or $8,160 per product.
    We have no way of determining any necessary follow-on actions, 
costs, or the number of products that may need these actions.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    (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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 adding the following new AD:

2015-16-06 British Aerospace Regional Aircraft: Amendment 39-18231; 
Docket No. FAA-2015-1744; Directorate Identifier 2015-CE-016-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective September 
21, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to British Aerospace Regional Aircraft Jetstream 
Model 3201 airplanes, all serial numbers, that are:
    (1) Certificated in any category; and
    (2) Modified in service following BAE Systems (Operations) Ltd 
Service Bulletin (SB) 05- JM8229.

(d) Subject

    Air Transport Association of America (ATA) Code 57: Wings.

(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 the in-service 
special detailed inspection technique required for the Jetstream 
3200's life extension program was delayed; consequently, the in-
service special detailed inspection (SDI) technique is not formally 
part of the life extension program and may therefore not be 
accomplished as intended. We are issuing this AD to detect and 
correct cracking in the wing main spar, which could result in 
structural failure of the wing with consequent loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions as specified in 
paragraphs (f)(1) through (f)(3) of this AD:
    (1) Before accumulating a total of 53,950 flight cycles (FC) on 
the airplane or within the next 50 FC after September 21, 2015 (the 
effective date of this AD), whichever occurs later, and repetitively 
thereafter at intervals not to exceed 14,300 FC, accomplish an eddy 
current (EC) and an x-ray inspection of the wing main spar around 
rib 36 following the instructions of British Aerospace Jetstream 
Series 3100 & 3200 Service Bulletin 57-JA140140, Original Issue, 
dated June 26, 2014. For the purposes of this AD, owner/operators 
who do not track total FC must multiply the total number of airplane 
hours time-in-service (TIS) by 0.75 to calculate the cycles.
    (2) If any crack or corrosion is found during any inspection 
required by paragraph (f)(1) of this AD, before further flight, 
contact BAE Systems (Operations) Ltd for FAA-approved repair 
instructions approved specifically for this AD and accomplish those 
instructions. You can find contact information for BAE Systems 
(Operations) Ltd in paragraph (i)(3) of this AD. Use the Operator 
Report Form and follow the instructions in British Aerospace 
Jetstream Series 3100 & 3200 Service Bulletin 57-JA140140, Original 
Issue, dated: June 26, 2014.
    (3) Repair of an airplane as required in paragraph (f)(2) of 
this AD does not terminate the repetitive inspections required in 
paragraph (f)(1) of this AD for that airplane, unless the approved 
repair instructions state otherwise.

(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

[[Page 49132]]

to assure the product is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, a federal agency may not conduct or sponsor, and a person 
is not required to respond to, nor shall a person be subject to a 
penalty for failure to comply with a collection of information 
subject to the requirements of the Paperwork Reduction Act unless 
that collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the
