Airworthiness Directives; Rockwell Collins, Inc. Transponders

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Rockwell Collins TDR-94 and TDR-94D Mode select (S) transponders that 
are installed on airplanes. This 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 AD requires inspecting the setting of 
the airplane type code category strapping and requires 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 issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective October 14, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 14, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Rockwell Collins 
TDR-94 and TDR-94D Mode select (S) transponders that are installed on 
airplanes. The NPRM published in the Federal Register on May 22, 2014, 
(79 FR 29384). The NPRM 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.
    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.
    The NPRM proposed to 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 
issuing this AD to correct the unsafe condition on these products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to the comment.

Request

    Kevin Lorrigan requested we add Beechcraft Models B300, B300C, and 
Hawker 900XP airplanes to paragraph (c), Applicability, to the AD 
because typically these airplanes are equipped with the TDR-94 or TDR-
94D transponders with weight-on-wheels input.
    The FAA agrees those airplanes were equipped with the TDR-94 or 
TDR-94D transponders when they were delivered from the factory. 
However, we disagree with adding these airplanes to paragraph (c), 
Applicability, of the AD. After we consulted with Beechcraft and 
reviewed their production records, we determined these airplanes are 
unaffected in their original ``as-delivered'' configurations. The 
airplanes were delivered with the TDR-94 or TDR-94D transponders, but 
they were strapped in such a manner that they remain unaffected.
    Paragraph (c), Applicability, of this AD is not intended as all-
inclusive. Paragraph (c) of this AD states, ``. . . transponders that 
are installed on but not limited to the airplanes . . .'' and gives a 
partial listing of airplanes known to have the affected transponders 
installed. Due to the possibility of modification of the airplane after 
delivery, each owner must evaluate the airplane's current configuration 
to determine compliance with the AD.
    We did not change the final rule AD action based on this comment.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial

[[Page 53289]]

changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 29384, May 22, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 29384, May 22, 2014).

Costs of Compliance

    We estimate that this AD affects 8,000 products installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with 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),
    (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.

(e) Unsafe Condition

    This 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. We are issuing this AD to detect and correct Mode S 
transponders that do not respond correctly to Mode S Only All-Call 
interrogations, which could result in increased pilot and air 
traffic controller workload as well as reduced separation of 
airplanes.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection

    Within the next 2 years after October 14, 2014 (the effective
