Congestion Management Rule for LaGuardia Airport Supplemental Notice of Proposed Rulemaking (NSNPRM) SUMMARY: On August 29, 2006, the Federal Aviation Administration published a notice of proposed rulemaking to address congestion at New York's LaGuardia Airport (LaGuardia), which included a proposal to administratively incentivize carriers to use larger planes. The FAA prefers to use measures that allow carriers to respond to market forces to drive the most efficient airline behavior and is amending its original proposal. To minimize disruption, the FAA proposes to grandfather the majority of operations at the airport and develop a robust secondary market by annually auctioning off a limited number of slots. The FAA is proposing two different, mutually exclusive options. Under the first option, the FAA would auction off and retire a portion of the slots and would use the proceeds to mitigate congestion and delay in the New York City area. Under the second option, the FAA would conduct an auction as it would under the first option, but the proceeds would go to the carrier holding the slot rather than the FAA and no portion of existing slots would be retired. This proposal also contains provisions for use-or-lose, unscheduled operations, and withdrawal for operational need. The FAA proposes to sunset the rule in ten years.

Airworthiness Directives; Turbomeca Makila 1A and 1A1 Turboshaft Engines Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for Turbomeca Makila 1A, 1A1, and 1A2 turboshaft engines. That AD currently requires replacing certain digital electronic control units (DECUs) and electronic control units (ECUs) with modified DECUs and ECUs. This AD applies only to Makila 1A and 1A1 turboshaft engines, and requires replacing the selector-comparator board in the ECU with a board incorporating Turbomeca modification TU 250. This AD results from recent unexplained reversions of the ECU to the 65% N1 back-up mode. We are issuing this AD to prevent dual-engine continued operation at 65% N1 after reversion of the ECU to the 65% N1 back-up mode due to temporary loss of N2 speed signal, which could lead to inability to continue safe flight, emergency autorotation landing, or an accident.

Certification of Aircraft and Airmen for the Operation of Light-Sport Aircraft; Modifications to Rules for Sport Pilots and Flight Instructors With a Sport Pilot Rating Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to amend its rules for sport pilots and flight instructors with a sport pilot rating. The FAA believes these changes are necessary to address airman certification issues that have arisen since regulations for the operation of light-sport aircraft were implemented. These changes would align the certification requirements for sport pilots and flight instructors with a sport pilot rating with those requirements currently applicable to other airmen certificates.

Use of Radar in Instrument Approach Procedures Final rule; Technical Amendment SUMMARY: This final rule corrects an inaccurate cross-reference citation in one of the FAA regulations. This correction is necessary to direct the reader to the actual paragraph that addresses the use of radar in instrument approaches.

Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes Correction In rule document E8-4671 beginning on page 13103 in the issue of Wednesday, March 12, 2008, make the following correction: On page 13106, in US dollars39.13, in table 3, the heading ''Table 3.-All Material Incorporated by reference'' should read ''Table 3.-New Material Incorporated by reference''

Damage Tolerance and Fatigue Evaluation of Structure Final rule; Technical Amendment SUMMARY: This action corrects a paragraph reference that appeared in the final rule, Airworthiness Standards; Airframe Rules Based on European Joint Aviation Requirements, which the FAA published in the Federal Register on February 9, 1996. In that final rule, the FAA inadvertently changed a paragraph reference. The intent of this action is to correct the error in the regulation to ensure the requirement is clear and accurate.
