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.
