[Docket No. FAA-2019-0129; Product Identifier 2019-NE-01-AD]
Airworthiness Directives; B/E Aerospace Fischer GmbH Common Seats
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: We propose to adopt a new airworthiness directive (AD)
certain B/E Aerospace Fischer GmbH Common Seats 170/260 H160. This
proposed AD was prompted by the discovery during testing that the
energy absorber (EA) may not function as intended during emergency
landing. This proposed AD would require removing and replacing the EA
assemblies on the affected seats. We are proposing this AD to address
the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by May 24,
ADDRESSES: You may send comments, using the procedures found in
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the

The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA AD 2018-0223, dated October 17, 2018 (referred to after
this as "the MCAI"), to address the unsafe condition on these
products. The MCAI states:
During dynamic tests of the seat energy absorber, a too long
stroke was identified. Analysis indicated that, when the seat is
used in low height adjustment during an emergency landing, the
energy absorber may not function as intended.
This condition, if not corrected, could lead to impact on lower
stop of the energy absorber stroke, possible resulting in injury to
the seat occupant.
To address this unsafe condition, B/E Aerospace Fischer issued
the SB, providing instructions to replace the seat energy absorber
assembly and to re-identify the seat.
For the reason described above, this [EASA] AD requires
modification of the affected seats and reidentification.
You may obtain further information by examining the MCAI in the AD
docket on the internet at http://www.regulations.gov by searching for
and locating Docket No. FAA-2019-0129.
Related Service Information Under 1 CFR Part 51
We reviewed B/E Aerospace Fischer Alert Service Bulletin (ASB) No.
SB0718-004, Issue A, dated June 26, 2018. The ASB describes procedures
for removing and replacing the EA assemblies on Common Seats 170/260
H160. 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.
This product has been approved by EASA and is approved for
operation in the United States. Pursuant to our bilateral agreement
with the European Community, EASA has notified us of the unsafe
condition described in the MCAI and service information referenced
above. We are proposing this AD because we evaluated all the relevant
information provided by EASA 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 removing and replacing the EA
assemblies on the affected common seats.
Costs of Compliance
We estimate that this proposed AD affects 341 common seats
installed on aircraft of U.S. registry.
We estimate the following costs to comply with this proposed AD:
|Inspect to determine if re-work
has been accomplished.
||0.2 work-hours x $85 per hour
|Replace EA Assembly.
||3 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. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
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
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.
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
(1) Is not a "significant regulatory action" under Executive
(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.
