Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0212, 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 
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.

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.

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.

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 for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85             $340
----------------------------------------------------------------------------------------------------------------


[[Page 30379]]

    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 = $85.....................  Up to $1,734................  Up to $1,819.
----------------------------------------------------------------------------------------------------------------

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.
