AGENCY: Federal Aviation Administration (FAA), DOT.

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

[[Page 22520]]

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.
