transponders respond intermittently to 

Mode S interrogations from both 

ground-based and traffic collision 

avoidance system (TCAS-) equipped 

airplanes. This AD requires testing and 

calibration of the alignment of the 

transponders. We are issuing this AD to 

correct the unsafe condition on these 

products.

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 TPR– 

720 and TPR–900 Mode select (S) 

transponders that are installed on 

airplanes. The NPRM published in the 

Federal Register on November 19, 2013 

(78 FR 69318). The NPRM proposed to 

require testing and calibration of the 

alignment of the TPR–720 and TPR–900 

Mode S transponders. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request FAA Review Impact on AD 92– 

11–09 (57 FR 20744, May 15, 1992) 

Konstantinos Sideris of Airbus 

commented that AD 92–11–09 (57 FR 

20744, May 15, 1992) required 

converting part number (P/N) 622– 

7878–020 into P/N 622–7878–301. The 

commenter stated that the proposed AD 

would affect both of those P/Ns, and he 

requested the FAA review the impact of 

the proposed AD on AD 92–11–09 and 

consider cancelling AD 92–11–09. 

After review, we disagree with 

cancelling AD 92–11–09 (57 FR 20744, 

May 15, 1992). This AD requires a 

different task than that required in AD 

92–11–09 and assures timely test and 

calibration for all affected P/Ns, 

including those affected and referenced 

in AD 92–11–09. 

We did not change the final rule AD 

action based on this comment. 

Request FAA Add and Delete Specific 

Model Airplanes from Applicability 

The Boeing Company requested we 

add Models 737 classics, 737NG, 757, 

and 767 airplanes to the Applicability 

and exclude the Model 747–8. 

We agree that this AD may apply to 

Models 737, 757, and 767 airplanes; 

however, 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. In our discussions with 

Rockwell Collins, they discussed that 

the subject transponders may be 

installed by supplemental type 

certificate on models other than the 

models that are known to have the 

affected transponders installed. 

We added language to paragraph (c), 

Applicability, to clarify that the listing 

of airplanes is not all-inclusive. 

Request FAA Change the Cost of 

Compliance Estimate 

The Boeing Company requested we 

adjust the total estimated cost of 

compliance to account for the added 

airplane models the commenter 

requested we add. 

We disagree with this comment. We 

based the estimated cost of compliance 

on the number of transponder units 

produced by Rockwell Collins, not the 

estimated number of airplanes that may 

have the transponders installed. 

We did not change the final rule AD 

action based on this comment. 

Request FAA Change the Language of 

the Required Action 

Craig Amadeo of Delta Airlines 

requested we change the language in the 

AD to clarify that the operators do not 

have to return the transponders to 

Rockwell Collins for the testing and 

calibration. Delta has full capability to 

test and align the receiver of the affected 

transponders. The commenter also 

requested we add more specific 


tkelley on DSK3SPTVN1PROD with RULES
17398 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Rules and Regulations 

language to the AD to clarify the testing 

and calibration procedures from the 

component maintenance manual (CMM) 

required by the AD. 

We agree that the operators do not 

need to return the transponders to 

Rockwell Collins for the testing and 

calibration. Any properly certified 

repair facility may do the required work. 

We also agree mechanics should know 

the applicable procedures to use from 

the CMM. However, the AD directs 

mechanics to the Rockwell Collins 

service information that references the 

specific procedures and figures to use 

for the required work. We do not agree 

that quoting the service information in 

the AD is necessary. 

We added language to the final rule 

AD action to clarify operators do not 

need to return the transponders to 

Rockwell Collins for the required testing 

and calibration. 

Request for Different Service 

Information 

Robert Semar of United Airlines 

stated that a normal shop visit with the 

transponders does not accomplish the 

testing required by this AD. We infer the 

commenter wants more service 

information. 

We agree that a normal shop visit will 

not accomplish the testing required by 

this AD; however, we disagree that more 

service information is required. The 

service letter referenced in the AD 

identifies the specific procedures 

required to comply with the AD. 

We did not change the final rule AD 

action based on this comment. 

Request FAA Change Cost of 

Compliance 

Robert Semar of United Airlines 

requested we add the cost of removal/ 

installation of the transponders to the 

cost of compliance section of the AD. 

We agree and have added the cost to 

remove and reinstall the transponders to 

the estimated cost of compliance for this 

AD action. 

Request Confirmation of the 

Applicability 

Kevin Hallworth requested we 

confirm whether the AD should also 

apply to the Rockwell Collins TPR–901, 

TDR–94, and TDR–94D Mode S 

transponders. The commenter asked if 

they are similarly affected. 

We have confirmed that the TPR–901 

is not affected by this AD. The 

associated circuitry in the TPR–901 is 

significantly different than that of the 

affected transponders. The TDR–94 and 

TDR–94D transponders are not affected 

by this issue and are not part of this AD 

action. 

We did not change the final rule AD 

action based on this comment. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

69318, November 19, 2013) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 69318, 

November 19, 2013). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Costs of Compliance 

We estimate that this AD affects 4,000 

products that are 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 

Removal and reinstallation of the transponders ......... 2 × $85 per hour = $170 Not applicable .................. $170 $680,000 

Test and calibration of the transponders .................... 4 × $85 per hour = $340 Not applicable .................. 340 1,360,000 

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.
