Federal Aviation Administration January 23, 2012 – Federal Register Recent Federal Regulation Documents

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by test reports showing that failure of a retract port flexible hose of a main landing gear (MLG) retraction actuator could cause excessive hydraulic fluid leakage. This proposed AD would require a detailed inspection for defects and damage of the retract port flexible hose on the left and right MLG retraction actuator, and replacement of the flexible hose if needed. We are proposing this AD to detect and correct defects and damage of the retract port flexible hose which could lead to an undamped extension of the MLG and could result in MLG structural failure, leading to an unsafe asymmetric landing configuration.

We propose to adopt a new airworthiness directive (AD) for certain Model 767-200 and -300 series airplanes. This proposed AD was prompted by reports of fatigue cracking on the lower main sill inner chord of the hatch opening of the overwing emergency exit. This proposed AD would require repetitive inspections for cracking, corrosion damage, and any other irregularity of the lower main sill inner chord and surrounding structure, and repair if necessary. We are proposing this AD to detect and correct fatigue cracking on the lower main sill inner chord of the hatch opening of the overwing emergency exit, which could result in reduced structural integrity of the hatch opening of the overwing emergency exit and consequent rapid decompression of the airplane.

We are adopting a new airworthiness directive (AD) for BRP POWERTRAIN GMBH & CO KG Rotax 914 F2, 914 F3, and 914 F4 reciprocating engines. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as isolated manufacturing deviations reportedly found on the threads of a certain batch of fuel pressure regulators, part number (P/N) 887130, installed on Rotax 914 F series engines, which could result in fuel leakage during engine operation. We are issuing this AD to prevent fuel leaks, which could result in an in-flight fire and damage to the aircraft.

The FAA hereby provides notice of intent to release certain airport properties 0.55 acres at the Fort Myers International Airport, Fort Myers, FL from the conditions, reservations, and restrictions as contained in all grant agreements between the FAA and the Lee County Port Authority. The release of property will allow the Lee County Port Authority, owner of Fort Myers International Airport, to dispose of the property for other than aeronautical purposes. The property is located north of Daniels Parkway and Chana Court, near the intersection of Chamberlin Parkway, in Fort Myers, Florida. The parcels are currently designated as non-aeronautical use. The property will be released of its federal obligations to transfer ownership to Lee County. The release of the airport properties will facilitate the construction of a new direct interchange access to the airport from Interstate 75. Lee County will also transfer ownership of 1.93 acres of property north of Daniels Parkway and Chana Court to be used for drainage for the airport access road. The airport parcels to be released have an appraised Fair Market Value of $41,622. The value of the parcel to be received is $5,000, and the value of the proposed airport access improvement is estimated to be $500,620. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Fort Myers International Airport and the FAA Airports District Office.

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
