Automatic Dependent Surveillance-Broadcast (ADS-B) Out Performance Requirements to Support Air Traffic Control (ATC) Service; Extension of Comment Period, 64966-64968 [E7-22544]

Download as PDF 64966 Federal Register / Vol. 72, No. 222 / Monday, November 19, 2007 / Proposed Rules 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 have 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 that the 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); 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Background On October 5, 2007, the Federal Aviation Administration (FAA) issued Notice No. 07–15, Automatic Dependent Surveillance—Broadcast (ADS–B) Out performance requirements to support Air Traffic Control (ATC) service (72 FR 56947; October 5, 2007). Comments to that document were to be received on or before January 3, 2008. By request submitted to the docket on October 19, 2007, the Air Transport Association of America, Inc., Air Carrier Association of America, Civil Aviation Aerospace Industries Association, National Air Carrier Association, and Regional Airline Association requested that the FAA extend the comment period for Notice No. 07–15 for 60 days. The organizations requesting an extension noted that commenters ‘‘will have to develop as much information as possible as to future costs associated with implementing a final rule in order to provide meaningful input.’’ They also noted that the holiday season falls within the comment period and that the comment period is scheduled to close just after New Year’s Day. Because of the importance of the rulemaking, in terms of advancing Air Traffic modernization, and the potential costs on the aviation industry that would result from a final rule, they requested that the public comment period be extended for an additional 60 days. In addition, on November 1, 2007, the Aircraft Owners and Pilots Association submitted a request to extend the comment period for Notice No. 07–15 for 60 days. They noted that additional ‘‘time is needed to assess questions surrounding making a final rule that is financially feasible for general aviation, improves ATC services at general aviation airports, results in user cost avoidance, and improves general aviation safety.’’ On November 5, 2007, the Cargo Airline Association submitted a request to extend the comment period for Notice No. 07–15 for 60 days. They noted the extension was needed to provide meaningful input to the rulemaking process.

We must balance the length of the comment period against the need to proceed expeditiously with a key component in managing the anticipated growth in the use of the National Airspace System. The FAA believes an additional 60 days would be adequate for commenters to collect cost and operational data necessary to provide meaningful comment to Notice No. 07–15. The FAA does not anticipate any further extension of the comment period for this rulemaking. Extension of Comment Period In accordance with section 11.47(c) of title 14, Code of Federal Regulations, the FAA has reviewed the requests submitted by the: Air Transport Association of America, Inc., Air Carrier Association of America, Civil Aviation Aerospace Industries Association, National Air Carrier Association, and Regional Airline Association; Aircraft Owners and Pilots Association; and Cargo Airline Association for extension of the comment period to Notice No. 07–15. These petitioners have shown a substantive interest in the proposed rule and good cause for the extension.

Background

    On October 5, 2007, the Federal Aviation Administration (FAA) 
issued Notice No. 07-15, Automatic Dependent Surveillance--Broadcast 
(ADS-B) Out performance requirements to support Air Traffic Control 
(ATC) service (72 FR 56947; October 5, 2007). Comments to that document 
were to be received on or before January 3, 2008.
    By request submitted to the docket on October 19, 2007, the Air 
Transport Association of America, Inc., Air Carrier Association of 
America, Civil Aviation Aerospace Industries Association, National Air 
Carrier Association, and Regional Airline Association requested that 
the FAA extend the comment period for Notice No. 07-15 for 60 days. The 
organizations requesting an extension noted that commenters ``will have 
to develop as much information as possible as to future costs 
associated with implementing a final rule in order to provide 
meaningful input.'' They also noted that the holiday season falls 
within the comment period and that the comment period is scheduled to 
close just after New Year's Day. Because of the importance of the 
rulemaking, in terms of advancing Air Traffic modernization, and the 
potential costs on the aviation industry that would result from a final 
rule, they requested that the public comment period be extended for an 
additional 60 days.
    In addition, on November 1, 2007, the Aircraft Owners and Pilots 
Association submitted a request to extend the comment period for Notice 
No. 07-15 for 60 days. They noted that additional ``time is needed to 
assess questions surrounding making a final rule that is financially 
feasible for general aviation, improves ATC services at general 
aviation airports, results in user cost avoidance, and improves general 
aviation safety.''
    On November 5, 2007, the Cargo Airline Association submitted a 
request to extend the comment period for Notice No. 07-15 for 60 days. 
They noted the extension was needed to provide meaningful input to the 
rulemaking process.
    The FAA concurs with the petitioners' request for an extension of 
the comment period on Notice No. 07-15 for an additional 60 days, until

[[Page 64968]]

March 3, 2008. We must balance the length of the comment period against 
the need to proceed expeditiously with a key component in managing the 
anticipated growth in the use of the National Airspace System. The FAA 
believes an additional 60 days would be adequate for commenters to 
collect cost and operational data necessary to provide meaningful 
comment to Notice No. 07-15. The FAA does not anticipate any further 
extension of the comment period for this rulemaking.

Extension of Comment Period

    In accordance with section 11.47(c) of title 14, Code of Federal 
Regulations, the FAA has reviewed the requests submitted by the: Air 
Transport Association of America, Inc., Air Carrier Association of 
America, Civil Aviation Aerospace Industries Association, National Air 
Carrier Association, and Regional Airline Association; Aircraft Owners 
and Pilots Association; and Cargo Airline Association for extension of 
the comment period to Notice No. 07-15. These petitioners have shown a 
substantive interest in the proposed rule and good cause for the 
extension. The FAA has determined that extension of the comment period 
is consistent with the public interest, and that good cause exists for
