Discussion During flight inspection on a Bombardier Model CRJ–200 airplane, Nav Canada, which is Canada’s civil air navigation service provider, observed the FMS map displaying an incorrect turn for the Fort St. John airport instrument landing system runway 29 missed approach while using temperature compensation. Nav Canada assumed this was only an issue with the map display and reported the incident to Rockwell Collins. Rockwell Collins subsequently determined that an error in the design of the Pro Line 4 and Pro Line 21 FMC software causes changes to the procedure-defined turn direction when the procedure has been significantly modified. The FMS will change the planned database turn direction to an incorrect turn direction when the altitude climb field is edited, and the flight crew may not notice the change during climb. The FMS will also change the planned database turn direction to an incorrect turn direction if the temperature compensation is activated, which may go unnoticed by the flight crew with the increased workload involved with a missed approach procedure. Editing the altitude or using temperature compensation does not change the flight segment. However, due to the design error, the software thinks the flight segment has changed. The change of the planned turn direction can occur for either left or right turns. The FMS commanding incorrect turn direction may result in a collision or controlled flight into terrain. Related Service Information Under 1 CFR Part 51 We reviewed Rockwell Collins Service Information Letter, CSU–XX00– 18–1, dated June 27, 2018. The service letter contains procedures for disabling the automatic temperature compensation option in Pro Line 4 and Pro Line 21 FMC systems.

Airworthiness Directives; Rockwell Collins, Inc. Flight 
Management Systems

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Rockwell Collins, Inc. (Rockwell Collins) flight management 
systems (FMS) installed on airplanes. This proposed AD was prompted by 
reports of the flight management computer (FMC) software issuing 
incorrect turn commands when the altitude climb field is edited or the 
temperature compensation is activated on the FMS control display unit. 
This proposed AD would require disabling the automatic temperature 
compensation feature of the FMS through the configuration strapping 
units (CSU) and revising the airplane flight manual (AFM) Limitations 
section. We are proposing this AD to address the unsafe condition on 
these products.

DATES: We must receive comments on this proposed AD by January 22, 
2019.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    During flight inspection on a Bombardier Model CRJ-200 airplane, 
Nav Canada, which is Canada's civil air navigation service provider, 
observed the FMS map displaying an incorrect turn for the Fort St. John 
airport instrument landing system runway 29 missed approach while using 
temperature compensation. Nav Canada assumed this was only an issue 
with the map display and reported the incident to Rockwell Collins.
    Rockwell Collins subsequently determined that an error in the 
design of the Pro Line 4 and Pro Line 21 FMC software causes changes to 
the procedure-defined turn direction when the procedure has been 
significantly modified. The FMS will change the planned database turn 
direction to an incorrect turn direction when the altitude climb field 
is edited, and the flight crew may not notice the change during climb. 
The FMS will also change the planned database turn direction to an 
incorrect turn direction if the temperature compensation is activated, 
which may go unnoticed by the flight crew with the increased workload 
involved with a missed approach procedure. Editing the altitude or 
using temperature compensation does not change the flight segment. 
However, due to the design error, the software thinks the flight 
segment has changed. The change of the planned turn direction can occur 
for either left or right turns.
    The FMS commanding incorrect turn direction may result in a 
collision or controlled flight into terrain.

Related Service Information Under 1 CFR Part 51

    We reviewed Rockwell Collins Service Information Letter, CSU-XX00-
18-1, dated June 27, 2018. The service letter contains procedures for 
disabling the automatic temperature compensation option in Pro Line 4 
and Pro Line 21 FMC systems. We also reviewed Rockwell Collins Service 
Information Letter FMC-XX00-18-1, dated June 27, 2018. The service 
letter provides instructions for revising the

[[Page 62737]]

Limitations section of the AFM by adding prohibitions on editing 
altitudes for specific Pro Line 4 and Pro Line 21 Flight Management 
Systems. 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.

FAA's Determination

    We are proposing 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.

Proposed AD Requirements

    This proposed AD would require disabling the automatic temperature 
compensation feature on the FMS through the CSUs. This proposed AD 
would also require revising the Limitations section of the AFM by 
adding limitations on the use of the temperature compensation feature 
and the editing of altitudes.

Costs of Compliance

    We estimate that this proposed AD affects 2,855 products installed 
on airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed 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.
    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, domestic business 
jet transport airplanes, and associated appliances to the Director of 
the Policy and Innovation Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.
