SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all BAE Systems (Operations) Limited Model 4101 airplanes. The NPRM published in the Federal Register on June 14, 2018 (83 FR 27721). The NPRM was prompted by a determination that inspection E:\FR\FM\03OCR1.SGM 03OCR1 49787 Federal Register / Vol. 83, No. 192 / Wednesday, October 3, 2018 / Rules and Regulations requirements for a number of maintenance tasks are incorrect. The NPRM proposed to require a one-time detailed inspection of a certain fuselage frame and repair, if necessary, and a revision of the maintenance or inspection program, as applicable, to incorporate new or revised maintenance instructions and airworthiness limitations. We are issuing this AD to address cracking in fuselage frame 90, which could cause it to fail and thereby compromise the structural integrity of the aircraft pressure hull. We are also issuing this AD to address fatigue damage of various airplane structures, which could result in reduced structural integrity of the airplane. 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 revision of the maintenance or inspection program, as applicable, to incorporate new or revised maintenance instructions and airworthiness limitations. This 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 by 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 http:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0511. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM 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 this final rule 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 for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. 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 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. Costs of Compliance We estimate that this AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this AD: daltland on DSKBBV9HB2PROD with RULES ESTIMATED COSTS Action Labor cost Inspection ........................................................ 2 work-hours × $85 per hour = $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 VerDate Sep<11>2014 16:40 Oct 02, 2018 Jkt 247001 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 AD.

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. E:\FR\FM\03OCR1.SGM 03OCR1 49788 Federal Register / Vol. 83, No. 192 / Wednesday, October 3, 2018 / Rules and Regulations 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 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 and associated appliances to the Director of the System Oversight Division. Regulatory Findings 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 that 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. daltland on DSKBBV9HB2PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. The NPRM published in the Federal Register on May 11, 2018 (83 FR 21953). The NPRM was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate new and more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address reduced structural integrity of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2018–0026, dated January 30, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. The MCAI states: The airworthiness limitations and certification maintenance instructions for the Dassault Myste`re Falcon 50 aeroplanes, which are approved by EASA, are currently defined and published in the Dassault Myste`re Falcon 50 Aircraft Maintenance Manual (AMM) chapter 5–40. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition [i.e, reduced structural integrity of the airplane]. Consequently, EASA issued [EASA] AD 2016–0067 [which corresponds to FAA AD 2017–09–03, Amendment 39–18865 (82 FR 21467, May 9, 2017)] to require accomplishment of the maintenance tasks, and implementation of the airworthiness limitations, as specified in Dassault Myste`re Falcon 50 AMM chapter 5–40 Revision 23. Since that [EASA] AD was issued, Dassault issued Revision 24 of the Dassault Myste`re Falcon 50 AMM chapter 5–40, which introduces new and more restrictive maintenance requirements and/or E:\FR\FM\03OCR1.SGM 03OCR1

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all BAE Systems 
(Operations) Limited Model 4101 airplanes. The NPRM published in the 
Federal Register on June 14, 2018 (83 FR 27721). The NPRM was prompted 
by a determination that inspection

[[Page 49787]]

requirements for a number of maintenance tasks are incorrect. The NPRM 
proposed to require a one-time detailed inspection of a certain 
fuselage frame and repair, if necessary, and a revision of the 
maintenance or inspection program, as applicable, to incorporate new or 
revised maintenance instructions and airworthiness limitations.
    We are issuing this AD to address cracking in fuselage frame 90, 
which could cause it to fail and thereby compromise the structural 
integrity of the aircraft pressure hull. We are also issuing this AD to 
address fatigue damage of various airplane structures, which could 
result in reduced structural integrity of the airplane.
    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 
revision of the maintenance or inspection program, as applicable, to 
incorporate new or revised maintenance instructions and airworthiness 
limitations. This 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 by 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 http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0511.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM 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 this final rule 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 for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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 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.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection............................  2 work-hours x $85 per                $0            $170            $680
                                         hour = $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 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.

[[Page 49788]]

    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 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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 that 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.
