RIN 2120-AA64
Airworthiness Directives; Rockwell Collins, Inc. Transponders
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 TPR-720 and TPR-900 Mode select (S)
transponders that are installed on airplanes. This proposed AD was
prompted by the identification that the TPR-720 and TPR-900 Mode S
transponders respond intermittently to Mode S interrogations from both
ground-based and traffic collision avoidance system (TCAS-) equipped
airplanes. This proposed AD would require testing and calibration of
the alignment of the transponders. We are proposing this AD to correct
the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by January 3, 2014.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.
Fax: 202-493-2251.

Discussion
FAA surveillance and testing of Mode S transponders, associated
with an upcoming change to the National Airspace System (NAS) ground-
based system software, exposed a deficiency in the capability of the
Rockwell Collins TPR-720 and TPR-900 series transponders to properly
respond to Mode S interrogations from both ground-based radars and
TCAS-equipped airplanes.
FAA and Rockwell Collins, Inc. investigated the deficiency with the
transponders and determined that age and lack of depot-level
maintenance may cause a shift in the sync phase reversal tolerance
causing intermittent replies to the Mode S and TCAS II interrogations.
The transponder receiver
[[Page 69319]]
misalignment requires calibration to correct the problem.
This unsafe condition, if not corrected, could result in possible
misalignment issues with the transponders that could lead to increased
pilot and air traffic controller workload as well as reduced separation
of airplanes.
Relevant Service Information
Rockwell Collins, Inc. issued Service Information Letter 13-1, 523-
0821603-101000, Revision No. 1, dated October 24, 2013. The service
letter describes procedures for testing the transponders for proper
alignment.
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 testing and calibration of the
alignment of the TPR-720 and TPR-900 Mode S transponders.
Costs of Compliance
We estimate that this proposed AD affects 4,000 products that are
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
----------------------------------------------------------------------------------------------------------------
Test and calibration of the 4 x $85 per hour = Not applicable...... $340 $1,360,000
transponders. $340.
----------------------------------------------------------------------------------------------------------------
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
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.
