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 TDR-94 and TDR-94D Mode select (S) 
transponders that are installed on airplanes. This proposed AD was 
prompted by instances where the TDR-94 and TDR-94D Mode S transponders 
did not properly respond to Mode S Only All-Call interrogations when 
the airplane transitioned from a ground to airborne state. This 
proposed AD would require inspecting the setting of the airplane type 
code category strapping and require either modifying the airplane type 
code category setting or installing the software upgrade to convert the 
affected transponders to the new part number. We are proposing this AD 
to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by July 7, 2014.

receive about this proposed AD.

Discussion

    We were notified that Bombardier CL604 airplanes in Eurocontrol 
airspace were not transmitting the appropriate Mode S replies. In at 
least one case, the flight crews switched to the other installed 
transponder, resulting in normal operation. Rockwell Collins, Inc. 
confirmed that other types of airplane could exhibit this same unsafe 
condition. As a result of the issue in Eurocontrol airspace, EASA 
issued Airworthiness Directive 2010-0003R1, effective date January 11, 
2010.
    The TDR-94 and TDR-94D Mode S transponder internal software does 
not correctly implement the air/ground override function when the 
airplane type code strapping is set to any value other than (1) or (0) 
and the airplane rotation speed is greater than 100 knots. The error in 
the air/ground override function inhibits the Mode S Only All-Call 
replies. This condition, if not corrected, could result in increased 
pilot and air traffic controller workload as well as reduced separation 
of airplanes.

Relevant Service Information

    We reviewed Rockwell Collins, Inc. Service Information Letter 07-2, 
Revision No. 1, 523-0810069-101000, dated September 2, 2008; Service 
Bulletin 505, 523-0816034-001000, dated September 2, 2008; Service 
Bulletin 507, 523-0816423-301000, dated Revision 3, dated December 5, 
2011; Service Bulletin 508, 523-0817821-001000, dated September 16, 
2009; and Service Bulletin 509, 523-0817822-001000, dated September 16, 
2009. The service information describes procedures for verifying the 
airplane type category strapping is correctly set and installing the 
software upgrade to convert the affected transponders to the new part 
number.

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 inspecting the setting of the 
airplane type code category strapping and require either modifying the 
airplane type code category setting or installing the software upgrade 
to convert the affected transponders to the new part number.

Costs of Compliance

    We estimate that this proposed AD affects 8,000 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.

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.
