Airworthiness Directives; Rockwell Collins, Inc. Traffic 
Surveillance System Processing Unit

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. TSS-4100 Traffic Surveillance System 
Processing Units that incorporate TSSA-4100 Field Loadable Software 
(FLS) Rockwell Collins part numbers 810-0052-002/ -003/-010/-011/-012/-
100/-101 and are installed on airplanes. This proposed AD was prompted 
by five

[[Page 30803]]

instances of air traffic control observing coasting (extrapolated stale 
data) of automatic dependent surveillance-broadcast data (position/
velocity data). This proposed AD would require installing the TSSA-4100 
FLS upgrades on the TSS-4100 units. We are proposing this AD to correct 
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by August 17, 2017.

Discussion

    We were notified of five instances of air traffic control observing 
coasting (extrapolated stale data) automatic dependent surveillance-
broadcast data (ADS-B position/velocity data) on a related Rockwell 
Collins, Inc. platform that shares a common architecture with the TSS-
4100 Traffic Surveillance System Processing Units, Rockwell Collins 
part number (RCPN) 822-2132-001, that are installed on airplanes. The 
affected units incorporate TSSA-4100 Field Loadable Software (FLS) 
RCPNs 810-0052-002/-003/-010/-011/-012/ -100/-101. An investigation of 
the events determined that the ADS-B position and the Mode S/traffic 
alert and collision avoidance system (TCAS) altitude of the TSS-4100 
are affected. The extrapolation of the data occurs with no warning to 
the crew.
    This condition, if not corrected, could result in misleading 
position and/or altitude being reported by the airplane. Misleading 
altitude data can adversely affect TCAS and possibly lead to mid-air 
collision due to an incorrect initial resolution advisory (RA) and/or 
an incorrect RA modification.

Related Service Information Under 1 CFR Part 51

    We reviewed Rockwell Collins Service Information Letter, TSSA-4100-
SIL-10-1, Revision No. 9, dated March 31, 2017. The service letter 
describes procedures for determining the part number of the affected 
FLS and the installation procedure for updating the FLS. 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 of this NPRM.

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 the same type design.

Proposed AD Requirements

    This proposed AD would require updating the TSSA-4100 FLS on the 
TSS-4100 Traffic Surveillance System Processing Unit.

Costs of Compliance

    We estimate that this proposed AD affects 1,000 products installed 
on airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Upgrade the FLS to RCPN 810-0052-013    1 work-hour x $85 per               $700            $785        $785,000
 or 810-0052-102.                        hour = $85.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered by the manufacturer, thereby reducing the cost impact 
on affected individuals. We do not control manufacturer coverage for 
affected individuals. As a result, we have included all costs in our 
cost estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 30804]]

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

    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.
