Discussion
We have received reports of
anomalies with the Aviation
81513
Communication & Surveillance Systems
(ACSS) Traffic Alert and Collision
Avoidance System (TCAS) units during
a flight test over a high density airport.
The TCAS units dropped several
reduced surveillance aircraft tracks
because of interference limiting. When
the TCAS unit interrogated aircraft in a
high density airport area, some of the
targets disappeared from the cockpit
display or were not recognized. One
occurrence of dropped tracks occurred
for 30 to 40 seconds of a 90-minute
flight segment. This condition, if not
corrected, could lead to possible loss of
separation of air traffic and possible
mid-air collision.
Relevant Service Information
We have reviewed the ACSS service
information specified in the following
table. The service information describes
procedures for upgrading software for
the ACSS TCAS to improve tracking of
nearby Mode-S intruders in high density
environments.

FAA’s Determination and Requirements
of This Proposed AD
We are proposing this AD because we
evaluated all relevant information and
determined the unsafe condition
described previously is likely to exist or
develop in other products of these same
type designs. This proposed AD would
require accomplishing the actions
specified in the service information
described previously.
Costs of Compliance
We estimate that this proposed AD
would affect 9,000 airplanes of U.S.
registry. We also estimate that it would
take about 2 work-hours per product to
comply with this proposed AD. The
average labor rate is $85 per work-hour.
Required parts would cost up to $2,870
per product. Based on these figures, we
estimate the cost of this proposed AD to

the U.S. operators to be up to
$27,360,000, or up to $3,040 per
product.
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

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,

3. Will not have a significant

on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

evaluation and the estimated costs of
compliance in the AD Docket.

Discussion
We have received reports of anomalies with the Aviation
Communication & Surveillance Systems (ACSS) Traffic Alert and Collision
Avoidance System (TCAS) units during a flight test over a high density
airport. The TCAS units dropped several reduced surveillance aircraft
tracks because of interference limiting. When the TCAS unit
interrogated aircraft in a high density airport area, some of the
targets disappeared from the cockpit display or were not recognized.
One occurrence of dropped tracks occurred for 30 to 40 seconds of a 90-
minute flight segment. This condition, if not corrected, could lead to
possible loss of separation of air traffic and possible mid-air
collision.
Relevant Service Information
We have reviewed the ACSS service information specified in the
following table. The service information describes procedures for
upgrading software for the ACSS TCAS to improve tracking of nearby
Mode-S intruders in high density environments.

FAA's Determination and Requirements of This Proposed AD
We are proposing this AD because we evaluated all relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs. This proposed AD would require accomplishing the actions
specified in the service information described previously.
Costs of Compliance
We estimate that this proposed AD would affect 9,000 airplanes of
U.S. registry. We also estimate that it would take about 2 work-hours
per product to comply with this proposed AD. The average labor rate is
$85 per work-hour. Required parts would cost up to $2,870 per product.
Based on these figures, we estimate the cost of this proposed AD to the
U.S. operators to be up to $27,360,000, or up to $3,040 per product.
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,
[[Page 81514]]
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979), and
3. 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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
List of Subjects in 14 CFR Part 39

Subject
(d) Air Transport Association (ATA) of America Code 34:
Navigation.
Unsafe Condition
(e) This AD results from reports of anomalies with TCAS units
during a flight test over a high density airport. The TCAS units
dropped several reduced surveillance aircraft tracks because of
interference limiting. The Federal Aviation Administration is
issuing this AD to prevent TCAS units from dropping tracks, which
could compromise separation of air traffic and lead to subsequent
mid-air collisions.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Upgrade Software
(g) Within 48 months after the effective date of this AD,
upgrade software for the ACSS TCAS, in accordance with the
Accomplishment Instructions of the applicable ACSS service bulletin
identified in Table 1 of this AD.
Note 1: ACSS Publication Number 8008233-001, dated June 4, 2010,
ATA Service Bulletin 9000000-34-6016, contains three part numbers
(P/Ns 9000000-10007, -20007, and -55007) which were never produced.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Los Angeles Aircraft Certification Office
(ACO), FAA, has the authority to approve AMOCs for this AD, if
requested using the procedures found in 14 CFR 39.19. Send
