(a) COMMENTS DUE DATE

    We must receive comments by April 8, 2019.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD  applies  to  AmSafe  Inc.  seatbelts  installed  on  various
    airplanes and rotorcraft, certificated in any category, including, but
    not  limited  to,  the airplanes  of  the  manufacturers specified  in
    paragraphs (c)(1) through (c)(5) of this AD.

(1) Airbus SAS

(2) The Boeing Company

(3) Bombardier, Inc.

(4) Embraer S.A.

(5) Fokker Services B.V.

(d) SUBJECT

    Air  Transport  Association  (ATA)  of  America  Code  25,  Equipment/
    furnishings.

(e) UNSAFE CONDITION

    This AD was prompted by reports of multiple failed keepers on seatbelt
    hook assemblies. We are issuing  this AD to address failed  keepers on
    seatbelt  hook  assemblies.  Failure  of  keepers  on  seatbelt   hook
    assemblies, if not addressed, could result in the seatbelt disengaging
    from and detaching from  the seat structure under  certain conditions,
    and could result in injury to passengers or flightcrew.

(f) COMPLIANCE

    Comply  with this  AD within  the compliance  times specified,  unless
    already done.

(g) INSPECTION FOR AFFECTED PARTS

    For any seatbelt buckle half  and connector half having a  part number
    listed in Table  1 of paragraph  "1.1., Effectivity" of  AmSafe Safety
    Bulletin SB505960-01, Issue 5, dated  August 6, 2018: Within 180  days
    after the effective date of this AD, do a general visual inspection of
    each seatbelt buckle half and connector half to determine whether  the
    seatbelt hook assembly has exposed springs, in accordance with  AmSafe
    Safety Bulletin SB505960-01, Issue 5, dated August 6, 2018.

(1) An affected part is any seatbelt buckle half or  connector  half  that
    has a seatbelt hook assembly with exposed springs.

(2) An unaffected part is any seatbelt buckle half or  connector half that
    has a seatbelt hook assembly without exposed springs.

(h) REPETITIVE INSPECTIONS AND FUNCTIONAL CHECKS

    Within 180  days after  the effective  date of  this AD,  do a general
    visual inspection  of each  affected part  for damage  to the seatbelt
    hook assembly  and do  a functional  check in  accordance with  AmSafe
    Safety Bulletin SB505960-01, Issue 5, dated August 6, 2018.

(1) If any  seatbelt hook assembly  is  damaged  or  the  part  fails  the
    functional check, before further flight,  replace the part with a  new
    or serviceable  part. If  an affected  part is  installed, repeat  the
    inspection and functional check at  intervals not to exceed 24  months
    or at  the next  scheduled heavy  maintenance check,  whichever occurs
    first, until  the actions  specified in  paragraph (i)  of this AD are
    done.

(2) If an affected part is undamaged and passes the functional check,  re-
    peat the inspection and functional check at intervals not to exceed 24
    months or  at the  next scheduled  heavy maintenance  check, whichever
    occurs first, until the actions specified in paragraph (i) of this  AD
    are done.

(i) TERMINATING ACTION

    Within 58  months after  the effective  date of  this AD,  replace all
    affected parts with unaffected parts in accordance with AmSafe  Safety
    Bulletin SB505960-01,  Issue 5,  dated August  6, 2018.  Replacing all
    affected  parts  with unaffected  parts  on a  seatbelt  hook assembly
    terminates the repetitive inspections and functional checks  specified
    in paragraph (h) of this AD for that seatbelt hook assembly. Replacing
    all affected parts with unaffected parts on an airplane or  rotorcraft
    terminates the repetitive inspections and functional checks  specified
    in paragraph (h) of this AD for that airplane or rotorcraft.

(j) PARTS INSTALLATION PROHIBITION

    No person  may install  on any  seat an  affected part  as of the time
    specified  in  paragraph (j)(1),  (j)(2),  or (j)(3)  of  this AD,  as
    applicable.

(1) For seats on which,  as of the effective date of this AD  any affected
    part is found during the inspection required by paragraph (g) of  this
    AD: After replacement of the affected part(s) with unaffected part(s).

(2) For seats on which no affected parts are found  during  the inspection
    required by paragraph (g) of this AD: As of the date of the inspection
    required by paragraph (g) of this AD.

(3) For seats on which both the seatbelt buckle half  and  connector  half
    have  part  numbers  not  listed   in  Table  1  of  paragraph  "1.1.,
    Effectivity"  of  AmSafe Safety Bulletin SB505960-01,  Issue 5,  dated
    August 6, 2018: As of the effective date of this AD.

(k) NO RETURN OF PARTS

    Although AmSafe Safety Bulletin SB505960-01, Issue 5,  dated August 6,
    2018, specifies to return parts to the manufacturer,  this AD does not
    require the return of the parts to the manufacturer.

(l) CREDIT FOR PREVIOUS ACTIONS

    This paragraph provides credit for the actions specified in paragraphs
    (g), (h), and (i) of this  AD, if those actions were performed  before
    the effective date of this AD using the service information  specified
    in paragraphs (l)(1) or (l)(2), of this AD.

(1) AmSafe Safety Bulletin SB505960-01, Issue 3, dated April 19, 2018.

(2) AmSafe Safety Bulletin SB505960-01, Issue 4, dated July 12, 2018.

Discussion

We have received a report indicating that failed keepers on
seatbelt hook assemblies have been found on multiple transport category
airplanes. These seatbelt hook assemblies might also be installed on
other types of aircraft. The keepers have been found with the metal
bridge above the spring bent or broken in a way that does not allow the
seatbelt hook assemblies to be securely fastened to the seat structure.
Failure of keepers on seatbelt hook assemblies, if not addressed, could
result in the seatbelt disengaging from and detaching from the seat
structure under certain conditions, and could result in injury to
passengers or flightcrew.

Related Service Information Under 1 CFR Part 51

We reviewed AmSafe Safety Bulletin SB505960-01, Issue 5, dated
August 6, 2018. The service information describes procedures for an
inspection for affected parts, repetitive general visual inspections of
the seatbelt hook assembly for damage (including compressed springs,
bends, rotation or deformation of the bridge), repetitive functional
checks and replacement. 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

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 designs.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified
in the service information described previously, except as discussed
under "Differences Between this Proposed AD and the Service
Information."

Differences Between This Proposed AD and the Service Information

AmSafe Safety Bulletin SB505960-01, Issue 5, dated August 6, 2018,
specifies to return parts to the manufacturer. This proposed AD would
not include that requirement.

Costs of Compliance

We estimate that this proposed AD affects 100,000 appliances
installed on, but not limited to, various airplanes and rotorcraft of
U.S. registry. We estimate the following costs to comply with this
proposed AD:

Estimated Costs

Action
Labor cost
Parts cost
Cost per product
Cost on U.S. operators
Inspection for affected part 1 work-hour x $85 per hour = $85 $0 $85 $8,500,000
Repetitive inspections and functional checks 1 work-hour x $85 per hour = $85 per inspection cycle 0 $85 per inspection cycle $8,500,000 per inspection cycle
Replacement 1 work-hour x $85 per hour = $85 28 $113 $11,300,000

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
Replacement 1 work-hour x $85 per hour = $85
$28
$113

According to the manufacturer, some or all 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 known costs in
our cost estimate.

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 and associated appliances 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
