Airworthiness Directives; Aspen Avionics, Inc.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Aspen Avionics, Inc., Evolution Flight Display (EFD) EFD1000 
Emergency Backup Display, EFD1000 Multi-Function Display, and EFD1000 
Primary Flight Display systems installed on various airplanes. This AD 
imposes operating restrictions on these display systems by revising the 
Limitations section of the airplane flight manual (AFM). This AD was 
prompted by an automatic reset occurring when the display internal 
monitor detects a potential fault, causing intermittent loss of 
airspeed, attitude, and altitude information during flight. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective August 17, 2020.
    The FAA must receive comments on this AD by September 14, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

    On February 25, 2020, Aspen Avionics, Inc. (Aspen), notified the 
FAA of 35 instances of software interacting with a graphics processing 
chip defect and causing an automatic reset to occur on Aspen EFD1000 
Emergency Backup Display, EFD1000 Multi-Function Display, and EFD1000 
Primary Flight Display systems. The reset occurs when the display 
internal monitor detects a potential fault. The display will go black 
and then it will restart, which lasts about 50 seconds. In 
installations where multiple Aspen EFDs serve as the primary and backup 
attitude, altitude, and airspeed displays instead of independent 
instruments; this repeat resetting may affect both Aspen units, 
resulting in loss of all attitude, altitude, and airspeed information 
during the reset period. Loss of all airspeed, attitude, and altitude 
information during flight may cause a loss of control of the airplane 
in instrument meteorological conditions (IMC) or at night. The actions 
required by this AD will restrict operations to flight under visual 
flight rules (VFR) and prohibit night operations to allow safe 
operation in the event of a loss of flight display functionality.

[[Page 45991]]

Related Service Information

    The FAA reviewed Aspen Operator Advisory OA2020-01, dated March 3, 
2020. This document advises operators of the automatic reset event and 
provides recommended operating limitations.
    The FAA also reviewed Aspen Service Bulletin Number: SB2020-01, 
dated April 1, 2020. This document provides instructions for updating 
the EFD software to correct the automatic reset issue. This AD does not 
apply to airplanes that are compliant with this service information.

FAA's Determination

    The FAA is issuing 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.

AD Requirements

    This AD requires revising the AFM limitations section to add 
language restricting operations to Day VFR only, either by making a pen 
and ink change or by inserting a copy of this AD.

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 attitude, altitude, and airspeed 
information during flight could result in loss of control of the 
airplane in IMC or at night. The required corrective actions must be 
accomplished before further flight, which does not allow the time 
necessary for the public to comment and for publication of the final 
rule. Therefore, the FAA finds good cause that notice and opportunity 
for prior public comment are impracticable. In addition, for the reason 
stated above, the FAA finds 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 the Docket Number FAA-2020-
0711 and Product Identifier MCAI-2020-00719-A at the beginning of your 
comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments we receive, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact we receive about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Mahmood 
Shah, Aerospace Engineer, Fort Worth ACO Branch, FAA, 10101 Hillwood 
Pkwy, Fort Worth, TX 76177. Any commentary that the FAA receives which 
is not specifically designated as CBI will be placed in the public 
docket for this rulemaking.

Costs of Compliance

    The FAA estimates that this AD affects 900 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

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.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

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, and
    (2) Will not affect intrastate aviation in Alaska.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 3410, FLIGHT ENVIRONMENT DATA; 3420, ATTITUDE 
AND DIRECTION DATA SYSTEM.

(e) Unsafe Condition

    This AD was prompted by an automatic reset occurring when the 
display internal monitor detects a potential fault causing 
intermittent loss of airspeed, attitude, and altitude information 
during flight. The FAA is issuing this AD to address the software 
interacting with a graphics processing chip defect. The unsafe 
condition, if not addressed, could result in intermittent loss of 
airspeed, attitude, and altitude information during flight with 
consequent loss of airplane control.

(f) Compliance

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

(g) Required Actions

    (1) Before further flight, revise the limitations section of the 
airplane flight manual (AFM) for your airplane by inserting a copy 
of this AD or by making a pen and ink change to add: ``Operation 
under Instrument Flight Rules (IFR) or night Visual Flight Rules 
(VFR) is prohibited.''
    (2) The action required by paragraph (g)(1) of this AD may be 
performed by the owner/operator (pilot) holding at least a private 
pilot certificate and must be entered into the aircraft records 
showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) 
through (4) and 14 CFR 91.417(a)(2)(v). The record must be 
maintained as required by 14 CFR 91.417. This authority is not 
applicable to aircraft being operated under 14 CFR part 119.

(h) Special Flight Permit

    Special flight permits are prohibited.

(i) 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 appropriate. If sending information directly to 
the manager of the certification office, send it to the attention of 
the person identified in paragraph (j).
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
