SUPPLEMENTARY INFORMATION: SUMMARY: PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 I. Introduction The Federal Trade Commission proposes amending its Fuel Rating Rule, 16 CFR part 306, to provide: (1) Revised rating, certification, and labeling requirements for blends of gasoline and more than 10 percent ethanol (‘‘ethanol blends’’); and 2) an additional octane rating method for gasoline. The Commission previously proposed amendments governing ethanol blends in a 2010 Notice of Proposed Rulemaking (‘‘2010 NPRM’’).1 After reviewing the comments, the Commission responded in April 2011 by publishing final amendments addressing other issues. Specifically, the Commission approved a new octane rating method and declined to amend the biodiesel and biomass-based diesel provisions.2 The Commission deferred consideration of ethanol blend labeling to consider an Environmental Protection Agency (‘‘EPA’’) decision permitting the use of ethanol blends between 10 to 15 percent concentration (‘‘E15’’) in 2001 and newer conventional vehicles.3 The Commission now proposes ethanollabeling amendments in response to comments received on the 2010 NPRM proposals, EPA’s action, and changes in an ASTM International specification regarding ethanol. The amendments proposed today retain the 2010 NPRM’s proposal that entities rate and certify all ethanol blends, but alter the proposed ethanol label’s disclosures, to provide consumers with more precise concentration and suitability information. The new proposed amendments also exempt EPA-approved E15 from the Commission’s labeling requirements. The Commission also proposes an additional octane rating method that 1 Federal Trade Commission: Automotive Fuel Ratings, Certification and Posting: Notice of Proposed Rulemaking (‘‘2010 NPRM’’), 75 FR 12470 (Mar. 16, 2010). 2 Federal Trade Commission: Automotive Fuel Ratings, Certification and Posting: Final Rule Amendments (‘‘2011 Final Amendments’’), 76 FR 19684 (Apr. 8, 2011). 3 EPA made this decision through a two-step process.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Hawker Beechcraft Corporation (Type Certificate previously held 
by Mitsubishi; Raytheon Aircraft Company) Model MU-300 airplanes, and 
Hawker Beechcraft Corporation (Type Certificate previously held by 
Raytheon Aircraft Company; Beech Aircraft Corporation) Model 400, 400A, 
and 400T airplanes. This proposed AD was prompted by multiple reports 
of fatigue cracking in the horizontal stabilizer ribs. This proposed AD 
would require repetitive inspections of the horizontal stabilizer rib 
assemblies for cracking, and replacement if necessary. We are proposing 
this AD to detect and correct such cracking, which could result in the 
failure of the horizontal stabilizer and loss of pitch control of the 
airplane.

Discussion

    We propose to adopt a new airworthiness directive (AD) for certain 
Hawker Beechcraft Corporation (Type Certificate previously held by 
Mitsubishi; Raytheon Aircraft Company) Model MU-300 airplanes, and 
Hawker Beechcraft Corporation (Type Certificate previously held by 
Raytheon Aircraft Company; Beech Aircraft Corporation) Model 400, 400A, 
and 400T airplanes. We have received multiple reports of fatigue 
cracking in the horizontal stabilizer ribs. This condition, if not 
corrected, could result in failure of the horizontal stabilizer and 
loss of pitch control of the airplane.

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.

[[Page 18849]]

Proposed AD Requirements

    This proposed AD would require repetitive radiographic (x-ray) 
inspections or borescope inspections for cracking of the horizontal 
stabilizer rib assemblies, and replacement if necessary, in accordance 
with a method approved by the Manager, Wichita Aircraft Certification 
Office (ACO), FAA.

Costs of Compliance

    We estimate that this proposed AD affects 735 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                                     Estimated Costs

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

                                               On-Condition Costs

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

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.

 (d) Subject

    Air Transport Association (ATA) of America Code 55, Stabilizers.

(e) Unsafe Condition

    This AD was prompted by multiple reports of fatigue cracking in 
the horizontal stabilizer ribs. We are issuing this AD to detect and 
correct such cracking, which could result in the failure of the 
horizontal stabilizer and loss of pitch control of the airplane.

[[Page 18850]]

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

 (g) Repetitive Inspections

    Before the accumulation of 7,400 total flight hours or within 6 
months after the effective date of this AD, whichever occurs later, 
perform a radiographic (x-ray) inspection or a borescope inspection 
for cracking of the horizontal stabilizer rib assemblies, in 
accordance with a method approved by the Manager, Wichita Aircraft 
Certification Office (ACO), FAA. Repeat the inspection thereafter at 
intervals not to exceed 2,400 flight hours. For an inspection method 
to be approved by the Manager, Wichita ACO, as required by this 
paragraph, the Manager's approval letter must specifically refer to 
this AD.

(h) Replacement

    If any cracking is found during any inspection required by 
paragraph (g) of this AD: Before further flight, replace the 
horizontal rib assemblies with new horizontal rib assemblies, in 
accordance with method to be approved by the Manager, Wichita ACO. 
For a replacement method to be approved by the Manager, Wichita ACO, 
as required by this paragraph, the Manager's approval letter must 
specifically refer to this AD. This replacement does not terminate 
the repetitive inspection requirements of paragraph (g) of this AD.

(i) Special Flight Permit

    Special flight permits may be issued in accordance with sections 
21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197

can be repaired (if the operator elects to do so), provided the 
restrictions specified in paragraphs (i)(1) through (i)(4) of this 
AD are followed.
    (1) Do not exceed 10 flight hours of operation.
    (2) Only operations under daylight conditions and under visual 
flight rules are allowed.
    (3) Only operations with the minimum flightcrew and with no 
passengers are allowed.
    (4) Do not exceed maneuver speed as specified in the applicable 
airplane flight manual.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Airframe Branch, ACE-118W, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
