ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Honeywell International Inc., Primus 

EPIC and Primus APEX flight 

management systems (FMS), as installed 

on the airplanes described above. This 

AD requires revising the Limitations 

section of the airplane flight manual to 

incorporate the procedures necessary to 

recover from or work around a software 

anomaly in the FMS. This AD results 

from discovery of software anomalies 

which, in certain situations, can cause 

the FMS to generate misleading 

navigational guidance to the pilots and 

to the autopilot system of various 

airplanes having this same system 

software. We are issuing this AD to 

provide the flightcrew with procedures 

to recover from or work around these 

software anomalies during flight, which 

could lead to an airplane departing from 

its scheduled flight path, and result in 

possible collision with other aircraft or 

terrain. 

DATES: This AD is effective May 14, 

2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of May 14, 2010. 

We must receive comments on this 

AD by June 14, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We were notified of two software 

anomalies discovered in the Honeywell 

Primus EPIC and Primus APEX flight 

management systems (FMS): The first 

anomaly can occur when the destination 

runway is changed without an arrival or 

approach entered and the runway is the 

TO waypoint, which causes the 

destination runway to become the 

departure runway; the second anomaly 

can occur when crossing the 180 degree 

meridian, which causes the FMS 

longitude position calculation to move 

by approximately 180 degrees. These 

software anomalies can cause the FMS 

to generate misleading navigational 

guidance to the pilots and to the 

autopilot system of various airplanes 

having this same system software. These 

conditions, if not corrected, could result 

in an airplane departing from its 

scheduled flight path, which could 

result in possible collision with other 

aircraft or terrain. 

Relevant Service Information 

We reviewed the Honeywell service 

information letters (SILs) specified in 

the following table. The SILs describe 

the procedures necessary to recover 

from or to work around the identified 

software anomalies in the FMS 

described above.

FAA’s Determination and Requirements 

of This AD 

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 

type designs. This AD requires 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Difference Between the AD and the 

Service Information.’’ 

Difference Between the AD and the 

Service Information 

The SILs identified in the previous 

table do not specify revising the AFMs 

of the affected airplanes to include the 

information in the General Information 

section of the SIL; however, this AD 

requires revising the applicable AFM to 

mstockstill on DSKH9S0YB1PROD with RULES

22520 Federal Register / Vol. 75, No. 82 / Thursday, April 29, 2010 / Rules and Regulations 

include that information in order to 

ensure that the flightcrew has the 

necessary procedures to recover from or 

work around the identified anomalies 

during flight. 

Interim Action 

We consider this AD interim action. 

The FMS manufacturer 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 

Certain Honeywell FMS software 

anomalies, in certain situations, can 

cause the FMS to generate misleading 

navigational guidance to the pilots and 

to the autopilot system of various 

airplanes having this same system. This 

misleading navigational guidance to the 

pilots and to the autopilot system causes 

the airplane to depart from its 

scheduled flight path, which could 

result in possible collision with other 

aircraft or terrain. We have determined 

that it is imperative that we notify 

flightcrews of these anomalies and 

provide them with procedures to 

recover from or work around these 

anomalies during flight. Because of our 

requirement to promote safe flight of 

civil aircraft and thus the critical need 

to assure proper navigational guidance 

from Honeywell FMS, coupled with the 

short compliance time involved with 

this action, this AD must be issued 

immediately. 

Because an unsafe condition exists 

that requires the immediate adoption of 

this AD, we find that notice and 

opportunity for prior public comment 

hereon are impracticable and 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 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2010–0385; Directorate Identifier 2010– 

NM–068–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this AD. We will consider all 

comments received by the closing date 

and may amend this AD 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 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. 

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. 

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), 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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.
