Models AT–602, AT–802, and AT– 802A Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: The FAA adopts a new airworthiness directive (AD) for all Air Tractor, Inc. Models AT–602, AT–802, and AT–802A airplanes. This AD requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. This AD results from reports of cracked engine mounts. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane. This AD becomes effective on December 1, 2006. As of December 1, 2006, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.

SUPPLEMENTARY INFORMATION: DATES: Discussion On April 26, 2006, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to all Air Tractor, Inc. Models AT–602, AT– 802, and AT–802A airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on May 2, 2006 (71 FR 25793). The NPRM proposed to require you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Comments We provided the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and FAA’s response to the comment: Labor cost Parts cost Total cost per airplane per inspection 1.5 work-hours × $80 per hour = $120 .................

Bush suggests that proper flight testing of a correctly instrumented engine mount and structure, combined with analysis of the data collected, may provide for a more efficient solution to the cracking problem than the repetitive inspections currently provide. He notes that the cost of each inspection is estimated at $120, and a properly substantiated terminating action may prove less costly over time. We partially agree that a properly executed flight test and analysis is a method to provide substantiating data that can be used to validate an alternate method for addressing the engine mount fatigue cracking. The FAA has not received any data at this time that proposes and substantiates a terminating action for the required inspections. If and when such information is received, we will consider mandating it through AD action. We are not changing the AD as a result of this comment. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Costs of Compliance We estimate that this AD affects 368 airplanes in the U.S. registry. We estimate the following costs to do each required inspection: Total cost on U.S. operators for initial inspection 368 × $120 = $44,160. estimate the following costs to do the replacement: Labor cost VerDate Aug<31>2005 Comment Issue: Flight Test and Analysis PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 Total cost on U.S. operators for initial inspection 368 × $10,462 = $3,850,016.

In this Final Rule, the Commission considers comments submitted in response to the NOPR, and as a result, makes certain modifications to the proposed regulatory revisions. Background 2. The Commission authorizes the construction and operation of proposed natural gas projects under NGA sections 3 and 7.5 However, the Commission does not have jurisdiction over every aspect of each natural gas project. Hence, for a natural gas project to go forward, in addition to Commission approval, several different agencies must typically reach favorable findings regarding other aspects of the project. To better coordinate the activities of separate agencies with varying responsibilities over proposed natural gas projects, EPAct 2005 modified the Commission’s role. Section 313 of EPAct 2005 directs the Commission (1) to establish a schedule for agencies to review requests for Federal authorizations required for a project 6 5 Under NGA section 7, the Commission has jurisdiction over the transportation or sale of natural gas in interstate commerce and the construction, acquisition, operation, and abandonment of facilities to transport natural gas in interstate commerce. Under NGA section 3(e), the Commission has exclusive authority to approve or deny an application for the siting, construction, expansion, or operation of a liquefied natural gas (LNG) terminal. The Secretary of the Department of Energy (DOE) has delegated to the Commission the authority under NGA section 3 to approve or disapprove applications for the siting, construction, and operation of facilities to import or export natural gas. The most recent delegation is in Delegation Order No. 00–004–00A, effective May 16, 2006. 6 EPAct 2005 section 313 describes ‘‘Federal authorizations’’ as decisions or actions by a Federal agency or official, ‘‘or State administrative agency or officer acting under delegated Federal authority,’’ granting or denying requests for permits, certificates, opinions, approvals, and other authorizations. The United States Environmental Protection Agency (EPA) asks what types of state actions would qualify as being under delegated Federal authority. The Commission finds that a state action qualifies as an action under delegated Federal authority if it is an action that (1) a State entity is permitted, approved, or directed to take under Federal law and (2) provides the basis for a reasoned decision on a request for a Federal authorization. The United States Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service (NMFS) asks whether a Federal authorization would include recommendations or biological opinions issued subsequent to consultations under the Magnuson-Stevens Fishery Conservation and Management Act and Endangered Species Act (ESA). To the extent recommendations and opinions are necessary for a Federal agency, or state agency acting under federally delegated authority, to reach a decision on a request for a Federal authorization that is needed for a proposed NGA section 3 or 7 project to go forward, the Commission interprets EPAct 2005’s mandate as encompassing such recommendations and opinions as ‘‘Federal authorizations.’’ E:\FR\FM\27OCR1.SGM 27OCR1

-----------------------------------------------------------------------

SUMMARY: The FAA adopts a new airworthiness directive (AD) for all Air 
Tractor, Inc. Models AT-602, AT-802, and AT-802A airplanes. This AD 
requires you to repetitively inspect the engine mount for any cracks, 
repair or replace any cracked engine mount, and report any cracks found 
to the FAA. This AD results from reports of cracked engine mounts. We 
are issuing this AD to detect and correct cracks in the engine mount, 
which could result in failure of the engine mount. Such failure could 
lead to separation of the engine from the airplane.

SUPPLEMENTARY INFORMATION:

Discussion

    On April 26, 2006, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to all Air Tractor, Inc. Models AT-602, AT-802, and AT-802A 
airplanes. This proposal was published in the Federal Register as a 
notice of proposed rulemaking (NPRM) on May 2, 2006 (71 FR 25793). The 
NPRM proposed to require you to repetitively inspect the engine mount 
for any cracks, repair or replace any cracked engine mount, and report 
any cracks found to the FAA.

Comments

    We provided the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and FAA's response to the comment:

Comment Issue: Flight Test and Analysis

    Ronald G. Bush suggests that proper flight testing of a correctly 
instrumented engine mount and structure, combined with analysis of the 
data collected, may provide for a more efficient solution to the 
cracking problem than the repetitive inspections currently provide. He 
notes that the cost of each inspection is estimated at $120, and a 
properly substantiated terminating action may prove less costly over 
time.
    We partially agree that a properly executed flight test and 
analysis is a method to provide substantiating data that can be used to 
validate an alternate method for addressing the engine mount fatigue 
cracking. The FAA has not received any data at this time that proposes 
and substantiates a terminating action for the required inspections. If 
and when such information is received, we will consider mandating it 
through AD action.
    We are not changing the AD as a result of this comment.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 368 airplanes in the U.S. 
registry.
    We estimate the following costs to do each required inspection:

----------------------------------------------------------------------------------------------------------------
                                                                      Total cost per      Total cost on U.S.
               Labor cost                        Parts cost            airplane per      operators for initial
                                                                        inspection            inspection
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $80 per hour = $120...  Not Applicable............            $120   368 x $120 = $44,160.
----------------------------------------------------------------------------------------------------------------

    We have no way of determining the number of airplanes that may need 
replacement of the engine mount. We estimate the following costs to do 
the replacement:

----------------------------------------------------------------------------------------------------------------
                                                                 Total cost per
                  Labor cost                      Parts cost      airplane per     Total cost on U.S. operators
                                                                   inspection         for initial inspection
----------------------------------------------------------------------------------------------------------------
81 work-hours x $80 per hour = $6,480........          $3,982          $10,462   368 x $10,462 = $3,850,016.
----------------------------------------------------------------------------------------------------------------


[[Page 62911]]

    Any required ``upon-condition'' repairs would vary depending upon 
the damage found during each inspection. Based on this, we have no way 
of determining the potential repair costs for each airplane.

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 AD.

Regulatory Findings

    We have determined that 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 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 summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2006-24228; Directorate Identifier 2006-CE-22-AD'' in your 
request.
