Airworthiness Directives; Rockwell

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Rockwell Collins TPR–720 and TPR– 

900 Mode select (S) transponders that 

are installed on airplanes. This 

proposed AD was prompted by the 

identification that the TPR–720 and 

TPR–900 Mode S transponders respond 

intermittently to Mode S interrogations 

from both ground-based and traffic 

collision avoidance system (TCAS-) 

equipped airplanes. This proposed AD 

would require testing and calibration of 

the alignment of the transponders. We 

are proposing this AD to correct the 

unsafe condition on these products. 

DATES: We must receive comments on 

this proposed AD by January 3, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

FAA surveillance and testing of Mode 

S transponders, associated with an 

upcoming change to the National 

Airspace System (NAS) ground-based 

system software, exposed a deficiency 

in the capability of the Rockwell Collins 

TPR–720 and TPR–900 series 

transponders to properly respond to 

Mode S interrogations from both 

ground-based radars and TCASequipped airplanes. 

FAA and Rockwell Collins, Inc. 

investigated the deficiency with the 

transponders and determined that age 

and lack of depot-level maintenance 

may cause a shift in the sync phase 

reversal tolerance causing intermittent 

replies to the Mode S and TCAS II 

interrogations. The transponder receiver 


TKELLEY on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 223 / Tuesday, November 19, 2013 / Proposed Rules 69319 

misalignment requires calibration to 

correct the problem. 

This unsafe condition, if not 

corrected, could result in possible 

misalignment issues with the 

transponders that could lead to 

increased pilot and air traffic controller 

workload as well as reduced separation 

of airplanes. 

Relevant Service Information 

Rockwell Collins, Inc. issued Service 

Information Letter 13–1, 523–0821603– 

101000, Revision No. 1, dated October 

24, 2013. The service letter describes 

procedures for testing the transponders 

for proper alignment. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

testing and calibration of the alignment 

of the TPR–720 and TPR–900 Mode S 

transponders. 

Costs of Compliance 

We estimate that this proposed AD 

affects 4,000 products that are installed 

on airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on 

U.S. operators 

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 

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, 

(2) Is not a ‘‘significant rule’’ under 

the 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.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No.: 

2013–0209, dated September 10, 2013 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

An event of a main landing gear (MLG) axle 

break during touchdown has been reported. 

The results of the subsequent technical 

investigation indicated that improper 

restoration of corrosion protection was the 

likely cause of the initial fatigue cracking. 

This condition, if not detected and 

corrected, could lead to failure of the main 

landing gear axle, possibly resulting in a 

runway excursion with consequent damage 

to the aeroplane and injury to the occupants. 

To address this potential unsafe condition, 

RUAG Aerospace Services GmbH issued 

Service Bulletin (SB) SB–228–300, Rev. 1. 

For the reason described above, this AD 

requires a one-time inspection of the MLG 

axle and, depending on findings, 

accomplishment of applicable corrective 

actions. 

You may examine the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2013–0962. 

Relevant Service Information 

RUAG Aerospace Services GmbH has 

issued Dornier 228 Service Bulletin No. 

SB–228–300, Revision 1, dated April 25, 

2013. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI.
