(d) SUBJECT

    Joint Aircraft System Component (JASC)/Air Transport Association (ATA)
    of America Code 34, Navigation.

(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 al-
    ready done.

(g) INSPECTION

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

    -02, Revision 1,  dated September 2,  2008. If the  airplane type code
    category  strapping is  set to  a value  of zero  (0) or  one (1),  no
    further action is required by this AD.

(h) MODIFICATION

    If the airplane type code category strapping is not set to a value  of
    zero (0)  or one  (1),  within  two years  after October 14, 2014 (the
    effective  date  of  this  AD),  do  the  actions  required  in either
    paragraph (h)(1) or (h)(2), to include all subparagraphs, of this AD.

(1) Modify the airplane type code category strapping setting to a value of
    zero  (0)  or  one  (1)  following  Rockwell  Collins,  Inc.   Service
    Information  Letter  07-2,  523-0810069-101000,  TDR-94()  SIL  07-02,
    Revision 1, dated September 2, 2008.

(2) Install  a  software  upgrade  to  convert  the  part  numbers  of the
    transponders  to the  new part  numbers using  the following  Rockwell

PREAMBLE 

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.

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
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:

Estimated Costs

Action Labor cost Parts cost Cost per product Cost on U.S.
operators
Inspect the setting of the airplane type category strapping. 1 work-hour x $85 per hour = $85 Not applicable $85 $680,000

We estimate the following costs to do any necessary corrections
that will be required based on the results of the inspection. We have
no way of determining the number of airplane that might need these
corrections:

On-Condition Costs

Action Labor cost Parts cost Cost per product
Modify the airplane type code category strapping. 1 work-hour x $85 per hour = $85 Not applicable $85
Convert the part number of the equipment. 2 work-hours x $85 per hour = $170 See conversion parts cost table. Varies depending on applicable part number or service bulletin.

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.
