Airworthiness Directives; Zodiac Aero Evacuation Systems

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Zodiac Aero Evacuation Systems fusible plugs installed on emergency 
evacuation equipment for various transport category airplanes. This 
proposed AD was prompted by reports indicating that affected fusible 
plugs activated (vented gas) below the rated temperature. This proposed 
AD would require an inspection of the fusible plugs to determine the 
part number, and lot number and replacement of all affected fusible 
plugs. We are proposing this AD to prevent the unsafe condition on 
these products.

DATES: We must receive comments on this proposed AD by January 3, 2017.

Discussion

    We have received reports indicating that certain fusible plugs 
installed on emergency evacuation equipment activated below the rated 
temperature. Fusible plugs are safety devices that vent air from 
charged inflation systems if the inflation systems encounter excessive 
temperatures. Tests conducted on affected fusible plugs revealed that 
the plugs activated (vented gas) between 130 and 150 degrees Fahrenheit 
([ordm]F) instead of the rated temperature of 174 [deg]F. The affected 
fusible plugs shipped from Air Cruisers, which is a component of Zodiac 
Aero Evacuation Systems, from October 1, 2008, through

[[Page 81710]]

October 1, 2009, and have part number (P/N) B13984-3, stamped with Lot 
PA-21 or PA-22. Currently there are 158 affected fusible plugs that 
have not been accounted for. Affected fusible plugs could be installed 
on emergency evacuation equipment, which includes all inflation valves, 
reservoir and valve assemblies, and evacuation slides, slides/rafts and 
liferafts. Activation of the fusible plugs vents all of the gas from 
the inflation system reservoir (inflation bottle), rendering the 
evacuation system unusable.

Related Service Information

    We reviewed Air Cruisers Service Information Letter 25-246, Rev. 
No. 1, dated February 21, 2014. The service information provides 
information regarding affected fusible plugs and provides guidance on 
fusible plug replacement.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require an inspection of the fusible plugs 
to determine the part number and lot number, and replacement of all 
affected fusible plugs. This proposed AD also would require, for 
affected part and lot numbers only, sending the part number 
identification results to Air Cruisers.

Costs of Compliance

    We estimate that this proposed AD affects 3,384 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per      Cost on  U.S.
              Action                        Labor cost            Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Determining part number...........  1 work-hour x $85 per                  $0              $85         $287,640
                                     hour = $85.
----------------------------------------------------------------------------------------------------------------

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

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost                   Parts cost           Cost per product
----------------------------------------------------------------------------------------------------------------
Replacing...........................  1 work-hour x $85 per hour  Not available...............               $85
                                       = $85.
Reporting...........................  1 work-hour x $85 per hour  $0..........................                85
                                       = $85.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

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 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.

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.
