Airworthiness Directives; Various

Surveillance Systems (ACSS) Traffic 

Alert and Collision Avoidance System 

(TCAS) Units 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for various 

aircraft equipped with certain ACSS 

TCAS units. This proposed AD would 

require upgrading software. This 

proposed 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. We are 

proposing this AD to prevent TCAS 

units from dropping tracks, which could 

compromise separation of air traffic and 

lead to subsequent mid-air collisions. 

DATES: We must receive comments on 

this proposed AD by February 11, 2011. 

ADDRESSES: You may send comments 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.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2010–1204; Directorate Identifier 

2010–NM–147–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

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, 


emcdonald on DSK2BSOYB1PROD with PROPOSALS
81514 Federal Register / Vol. 75, No. 248 / Tuesday, December 28, 2010 / Proposed Rules 

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.

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 information to Attn: Abby 

Malmir, Aerospace Engineer, Systems and 

Equipment Branch, ANM–130L, FAA, Los

(562) 627–5351; fax (562) 627–5210. 

(2) To request a different method of 

compliance or a different compliance time 

for this AD, follow the procedures in 14 CFR 

39.19. Before using any approved AMOC on 

any airplane to which the AMOC applies, 

notify your principal maintenance inspector
