14 CFR Part 39
[Docket No. FAA-2019-0260; Product Identifier 2017-NE-13-AD]
Airworthiness Directives; Ipeco Pilot and Co-Pilot Seats
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to supersede airworthiness directive
2017-22-02, which applies to certain Ipeco Holdings Limited (Ipeco)
pilot and co-pilot seats. AD 2017-22-02 requires modification and re-
identification of the affected seats. Since the FAA issued AD 2017-22-
02, Ipeco has received reports that the tracklock spring modification
required by AD 2017-22-02 does not adequately address the issue of
unexpected seat movement during takeoff and landing and the FAA also
determined the need to add additional seat part numbers (P/Ns) to the
applicability. This proposed AD would continue to require modification
and re-identification of the affected seats. This proposed AD would
also require initial and repetitive inspections of the affected
tracklock springs and, depending on the findings, replacement of the
tracklock springs with a part eligible for installation. The FAA is
proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by September

contact received about this proposed AD.
The FAA issued AD 2017-22-02, Amendment 39-19082 (82 FR 51552,
November 7, 2017), ("AD 2017-22-02"), for Ipeco pilot and co-pilot
seats. AD 2017-22-02 requires modification and re-identification of the
affected seats. AD 2017-22-02 resulted from reports of unexpected
movement of pilot and co-pilot seats during takeoff and landing. The
FAA issued AD 2017-22-02 to prevent unexpected movement of pilot and
co-pilot seats during takeoff and landing.
Actions Since AD 2017-22-02 Was Issued
Since the FAA issued AD 2017-22-02, Ipeco has received reports that
the tracklock spring modification required by AD 2017-22-02 does not
adequately address the issue of unexpected seat movement during takeoff
and landing. As a result, Ipeco published Ipeco Service Bulletin (SB)
063-25-14, Revision 00, dated August 14, 2018, providing instructions
to inspect and replace, if necessary, affected tracklock springs. Also,
since the FAA issued AD 2017-22-02, the European Union Aviation Safety
Agency (EASA) has issued AD 2018-0262, dated December 6, 2018, which
retains the requirements of EASA AD 2016-0256, dated December 16, 2016,
and also requires repetitive inspection of seats and, depending on
findings, replacement of affected tracklock springs. Based on
discussions with Ipeco and EASA, the FAA also determined the need to
add additional seat part numbers (P/Ns) to the applicability. These
seat P/Ns are included in the applicability of EASA AD 2018-0262.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Ipeco Service Bulletin (SB) Number 063-25-08,
Revision 00; SB Number 063-25-09, Revision 00; and SB Number 063-25-10,
Revision 00; all dated May 31, 2016.
The SBs provide instructions, differentiated by the part numbers of the
affected pilot and co-pilot seats, for the modification and re-
identification of these seats. The FAA also reviewed Ipeco SB Number
063-25-14, Revision 00, dated August 14, 2018. This SB provides
instructions for inspection and replacement, if necessary, of affected
tracklock springs. 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.
The FAA is proposing this AD because it 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 retain all of the requirements of AD 2017-
22-02. This proposed AD would add additional seat P/Ns to the
applicability. This proposed AD would also require initial and
repetitive inspections of the affected tracklock springs and, depending
on the findings, replacement of the tracklock springs with a part
eligible for installation.
Differences Between the Proposed AD and MCAI or Service Information
This proposed AD and EASA AD 2018-0262, dated December 6, 2018,
include pilot seat P/N 3A063-0099-01-1 and co-pilot seat P/N 3A063-
0100-01-1in their respective applicability sections, while Ipeco SB
Number 063-25-14, Revision 00, dated August 14, 2018, does not.
Costs of Compliance
The FAA estimates that this proposed AD affects 110 pilot and co-
pilot seats installed on, but not limited to, ATR-GIE Avions de
Transport Regional (ATR) 42 and ATR 72 airplanes of U.S. registry. The
FAA estimates that seats installed on 34 ATR 42 airplanes and seats
installed on 21 ATR 72 airplanes will require modification and
inspection. The FAA is revising the estimated number of affected seats
in this cost estimate to include two affected seats per airplane.
The FAA estimates the following costs to comply with this proposed
|Inspect ATR 42 flight crew seats.
||0.1 work-hours x $85 per hour
|Modify ATR 42 flight crew seats.
||2 work-hours x $85 per hour =
|Report results of ATR 42 inspection.
||1.0 work-hours x 85 per hour
|Inspect ATR 72 flight crew seats.
||0.1 work-hours x 85 per hour
|Modify ATR 72 flight crew seats.
||2 work-hours x 85 per hour =
|Report results of ATR 72 inspection.
||1.0 work-hours x 85 per hour
The FAA estimates the following costs
to do any necessary
replacements that would be required based on the results of the
proposed inspection. The FAA has no way of determining the number of
aircraft that might need these replacements:
|Remove seat and replace ATR 42
||1.4 work-hours x $85 per hour
|Remove seat and replace ATR 72
||1.4 work-hours x $85 per hour
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. The FAA does not control warranty coverage for
affected individuals. As a result, the FAA has included all 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 a 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 currently valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to be
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, completing and reviewing the collection of
information. All responses to this collection of information are
mandatory. Send comments regarding this burden estimate or any other
aspect of this collection of information, including suggestions for
reducing this burden to: Information Collection Clearance Officer,

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.
The FAA is 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
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 engines, propellers, and associated
appliances to the Manager, Engine and Propeller Standards Branch,
Policy and Innovation Division.
The FAA has 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
For the reasons discussed above, I certify that the proposed
(1) Is not a "significant regulatory action" under Executive
(2) Will not affect intrastate aviation in Alaska, and
(3) 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.
