Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all BAE 
Systems (Operations) Limited Model 4101 airplanes. This AD was prompted 
by a report of an improperly installed spacer around the electrical 
pins in the cartridge connector for the fire bottle extinguisher 
cartridge. This AD requires repetitive inspections for excessive or 
missing spacers, and applicable corrective actions. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective November 2, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 2, 
2018.

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 28, 2018 (83 FR 30377).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0212, dated October 25, 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:

    During scheduled maintenance (fire bottle extinguisher cartridge 
resistance check) it was noted that on the extinguisher cartridge, 
the blue spacer around the electrical pins appeared to be located 
too far forward. It was discovered that, inadvertently, an 
additional spacer (possibly from a previous extinguisher cartridge) 
was located in the extinguisher cartridge connector. This 
effectively shortens the electrical pins in the cartridge connector, 
which could result in insufficient engagement with the associated 
sockets on the aeroplane connector. A missing spacer would not 
affect the electrical connection between the extinguisher cartridge 
and the aeroplane wiring, but could allow moisture ingress over 
time.
    Both conditions, if not detected and corrected, could prevent 
the fire extinguisher bottle from discharging when required, 
possibly resulting in damage to the aeroplane and injury to 
occupants.
    To address this potential unsafe condition, BAE Systems 
(Operations) Ltd issued Service Bulletin (SB) J41-26-009, providing

[[Page 48939]]

inspection instructions to ensure that a single blue spacer is 
fitted on the inside of the extinguisher cartridge connector.
    For the reason described above, this [EASA] AD requires a one-
time [general visual] inspection [and inspection after a maintenance 
task that involves disconnection or re-connection of the electrical 
connector] of the extinguisher cartridge electrical connector and 
the aeroplane's electrical connector and, depending on findings, 
removal of excessive spacers or replacement of the fire extinguisher 
bottle.

    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-
0555.

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 Service Bulletin J41-
26-009, dated November 23, 2016. This service information describes 
procedures for a general visual inspection of the cartridge electrical 
connector and the aircraft electrical connector for missing or 
excessive spacers, and corrective actions including removing excessive 
spacers or replacing the fire bottle extinguisher cartridge. 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 for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators

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

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of any required 
actions. We have no way of determining the number of aircraft that 
might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
          Labor cost                Parts cost        Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour =    Up to $1,734.....  Up to $1,819.
 $85.

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 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.

accordance with the Accomplishment Instructions of BAE Systems 
(Operations) Limited Service Bulletin J41-26-009, dated November 23, 
2016.
    (3) If, during any inspection as required by paragraph (g) or 
(h) of this AD, as applicable, no blue spacer is found inside the 
cartridge electrical connector body: Before further flight, replace 
the cartridge in accordance with the Accomplishment Instructions of 
the BAE Systems (Operations) Limited Service Bulletin J41-26-009, 
dated November 23, 2016.
