    and 3420, Attitude and Direction Data System.

(e) UNSAFE CONDITION

    This AD was prompted by reports of repetitive uncommanded resetting of
    the flight display units.  We  are  issuing  this AD to prevent inter-
    mittent loss of airspeed, attitude, and  altitude  information  during
    flight. The unsafe condition,  if not addressed,  could result in loss
    of control  of  the  airplane  in Instrument Meteorological Conditions
    (IMC) or at night.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) REQUIRED ACTIONS

    Before the next flight in IMC or at night, or within 25 hours' time-in
    -service, whichever occurs first:

(1) Disable  the  Automatic  Dependent  Surveillance-Broadcast  (ADS-B) In
    function in each unit  by  following  the Procedure, paragraphs 5.2.a.
    and b.,  of  Aspen Avionics Mandatory Service Bulletin  No. SB2018-01,
    dated November 21, 2018 (SB2018-01); except, where SB2018-01 specifies
    contacting an Aspen Avionics dealer to disable  the ADS-B In function,
    this  AD  requires  disabling  the  ADS-B IN function  using  a method
    approved in accordance with paragraph (h) of this AD.

(2) Revise the Airplane Flight Manual Supplement in accordance  with para-
    graph 5.2.c of SB2018-01.

Note 1 to paragraph (g)(2) of this AD:  The AFM  for the aircraft affected
by this AD is required to be furnished  with the aircraft,  per 14 CFR 23.
1581.  Further, operators of the aircraft affected by this AD must operate
in accordance with the limitations specified in the AFM, per 14 CFR 91.9.

(h) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS)

(1) The Manager,  Fort Worth ACO Branch, FAA, has the authority to approve
    AMOCs for this AD, if requested  using the procedures found in 14  CFR
    39.19. In  accordance with  14 CFR  39.19, send  your request  to your
    principal  inspector  or  local  Flight Standards District Office,  as

SUPPLEMENTARY INFORMATION:

Discussion

On November 21, 2018, we issued SAIB SW-18-31 to alert owners and
operators of an airworthiness concern for aircraft with an Aspen
EFD1000 PFD, an EFD1000 MFD, an EFD1000 EBD, or an EFD500 MFD unit, as
installed by Supplemental Type Certificate (STC) No. SA10822SC. SAIB
SW-18-31 was prompted by 14 reports of flight display units repeatedly
resetting, uncommanded, in flight. In installations where multiple
Aspen EFDs provide redundancy, this repeat resetting may result in loss
of all altitude, attitude, and airspeed information during the reset
period. The units reset in five- to ten-minute intervals. For each
occurrence, it may take the display up to one minute to recover. While
the cause of this issue is under investigation, preliminary information
suggests that the cause may be related to the ADS-B In (FIS-B) Weather
Interface option installed on the units with software version 2.9. SAIB
SW-18-31 recommends restricting flight to flight under Visual Flight
Rules (VFR) only and suspending night operations to allow safe
operation in the event of loss of flight display functionality.
Alternatively, SAIB SW-18-31 recommends disabling the ADS-B In (FIS-B)
option, which is not required. SAIB SW-18-31 also requests that owners
and operators notify the FAA of aircraft that experience any similar
events.
SAIB SW-18-31 was issued to notify the public that an unsafe
condition may exist. Since we issued SAIB SW-18-31, additional analysis
of the reports of uncommanded resets and the nature of the possible
unsafe condition were evaluated, and we have determined that a more
urgent safety need requiring AD action is necessary. As a result, we
are adopting this AD for certain Aspen EFD1000 PFD, EFD1000 MFD,
EFD1000 EBD, and EFD500 MFD units installed on various airplanes. This
AD requires disabling the ADS-B In function and revising the AFMS to
reflect that the ADS-B In has been disabled on the unit. The actions
specified in this AD are intended to prevent intermittent loss of
airspeed, attitude, and altitude information during flight. The unsafe
condition, if not addressed, could result in loss of control of the
airplane in Instrument Meteorological Conditions (IMC) or at night.

Related Service Information Under 1 CFR Part 51

We reviewed Aspen Avionics Mandatory Service Bulletin No. SB2018-
01, dated November 21, 2018.

This service information contains procedures to disable the ADS-B In
function and revise the AFMS.
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.

Other Related Service Information

We reviewed Aspen Avionics AFMS No. 900-00008-001, Revision AD,
dated November 18, 2016, and approved December 8, 2016. This service
information contains general information, operating limitations,
emergency and normal procedures, performance information, weight and
balance information, and system description information for airplanes
with Aspen flight display units installed.

FAA's Determination

We are issuing 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 these same designs.

AD Requirements

This AD requires disabling the ADS-B In function in each installer
menu by changing the RS-232 INPUT for the bus connected to the ADS-B In
to NONE. This AD also requires revising the AFMS to reflect each
disabled unit.

Differences Between the AD and the Service Information

The service information specifies contacting an Aspen Avionics
dealer to disable the ADS-B In function, whereas this AD requires
contacting the FAA for approval of the procedure.

Interim Action

We consider this AD interim action. The design approval holder is
currently developing a modification that will address the unsafe
condition identified in this AD. Once this modification is developed,
approved, and available, we might consider additional rulemaking.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because intermittent loss of airspeed, attitude, and altitude
information during flight could result in loss of control of the
airplane in Instrument Meteorological Conditions (IMC) or at night. The
compliance time for the required action is shorter than the time
necessary for the public to comment and for publication of the final
rule. Therefore, we find good cause that notice and opportunity for
prior public comment are impracticable. In addition, for the reason
stated above, we find that good cause exists for making this amendment
effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include Docket No. FAA-2018-1085
and Product Identifier 2018-SW-100-AD at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this final rule. We will
consider all comments received by the closing date and may amend this
final rule because of those comments.
We will post all comments we receive, without change, to http://www.
regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this final rule.

Costs of Compliance

We estimate that this AD affects 2,000 aircraft of U.S. registry.
We estimate that operators may incur the following costs in order to
comply with this AD. Labor costs are estimated at $85 per work-hour.
Disabling the ADS-B In function and revising the AFMS would take
about 0.5 work-hour for an estimated cost of $43 per unit and up to
$258,000 for the U.S. fleet.

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 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 small airplanes, gliders,
balloons, airships, domestic business jet transport airplanes, and
associated appliances to the Director of the Policy and Innovation
Division.

Regulatory Findings

This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under 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.
