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. 


khammond on DSK30JT082PROD with RULES
210 Federal Register / Vol. 84, No. 15 / Wednesday, January 23, 2019 / Rules and Regulations 

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 workhour. 

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.
