Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2018-0259R1, dated February 7, 2019 (referred to after this as the
Mandatory Continuing Airworthiness Information, or "the MCAI"), to
correct an unsafe condition for the following airplanes on which
certain USB receptacles were installed using certain Fokker service
information:

Fokker Services B.V. Model F.27 Mark 050 airplanes.

Fokker Services B.V. Model F.28 Mark 3000 airplanes.

Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes.

Airbus SAS Model A318-111 airplanes.

Airbus SAS Model A319-111, -112, -114, -115, and -132 airplanes.

Airbus SAS Model A320-211, -212, -214, -231, -232, and -251N airplanes.

Airbus SAS Model A321-211, -231, -232, -251N and -253N airplanes.

Airbus SAS Model A330-202, -223, -243, -322 and -343 airplanes.

Airbus SAS Model A340-312 and -313 airplanes.

ATR--GIE Avions de Transport Regional Model ATR42-500 airplanes.

ATR--GIE Avions de Transport Regional Model ATR72-212 and -212A airplanes.

The Boeing Company Model 737-300, -400, -500, -700, -800
and -900ER series airplanes.

The Boeing Company Model 757-200 series airplanes.

The Boeing Company Model 767-200 and -300 series airplanes.

The Boeing Company Model 777-200LR series airplanes.

Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and
604 Variants) airplanes.

Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series
700, 701 & 702) airplanes.

Bombardier, Inc., Model DHC-8-202, -311, -315 and -402 airplanes.

The MCAI states:

Several occurrences on various aeroplanes have been reported of
smoke and fumes in the cockpit, due to overheating of an Electronic
Flight Bag (EFB) [universal serial bus] USB receptacle, which had
been installed by [Fokker Services] FS Supplemental Type Certificate
(STC), [service bulletin] SB, or minor modification, either an
Engineering Change Request (ECR) or Compliance Record Report (CRR),
as applicable. Investigation results revealed that each of these
events was caused by a short circuit in the EFB charging cable.

This condition, if not corrected, could lead to further events
of smoke/fumes in the cockpit, possibly resulting in excessive
flight crew workload and/or injury to flight deck occupants.

To address this unsafe condition, the USB manufacturer developed
a modification (change to USB receptacle [part number] P/N LS03-
05050-B), and Fokker Services published the applicable SB/EB to
provide those modification instructions, installing current limiting
and overheat protection.

For the reason described above, EASA issued AD 2018-0259 to
require modification of each affected part. That [EASA] AD also
prohibited (re)installation of affected parts.

Since that [EASA] AD was issued, FS issued Revision 2 of EBA320-
0167 and Revision 1 of EBDHC8-0035, redefining the affected
aeroplanes. It was determined that aeroplanes with EBA320-0151
embodied are not affected, as this involves a USB power supply from
another manufacturer. It was also determined that aeroplanes with FS
EBDHC8-0033 embodied (part of EASA STC 10046185) are not affected by
the [EASA] AD, as that mod is a holder-only installation. This
[EASA] AD is revised accordingly.

by searching for and locating Docket No. FAA-2019-0444.

FAA's Determination

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, the FAA
has been notified of the unsafe condition described in the MCAI and
service information referenced above. The FAA is proposing this AD
because we evaluated all the relevant information and determined the
unsafe condition described previously is likely to exist or develop on
other products of the same type design.

Proposed Requirements of This NPRM

This proposed AD would require accomplishing the actions specified
in the service information described previously.

Costs of Compliance

The FAA estimates that this proposed AD affects 14 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:

Estimated Costs for Required Actions

* The FAA has received no definitive data on the parts costs for the required actions.

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. The FAA does not control warranty
coverage for affected individuals. As a result, the FAA has 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.

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
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. 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.

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:
