Federal Aviation Administration April 2008 – 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 are revising an earlier proposed airworthiness directive (AD) that applies to certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. The earlier NPRM would have required you to replace the cabin door rod ends at the upper and lower hinges of the cabin door with newly designed rod ends. The earlier NPRM resulted from two known occurrences of in-flight cabin door separation (one total separation and one retained by the door strut). This proposed AD would require you to replace the cabin door rod ends with new parts including a redesigned non-binding hinge pin that replaces the existing pin at the upper door hinge. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these additional actions.

This action amends Class E airspace at Indianapolis, IN. Additional controlled airspace is necessary to accommodate aircraft using new RNA V Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Hendricks CountyGordon Graham Field, Indianapolis, IN. This action is necessary for the safety and management of Instrument Flight Rules (IFR) operations at Hendricks CountyGordon Graham Field, Indianapolis, IN.

The FAA proposes to supersede two existing airworthiness directives (ADs) that apply to all Short Brothers Model SD3-60 airplanes. One of the ADs currently requires inspection of the welded joints of the balance weight brackets for the elevator trim tabs for cracking; repetitive inspections, as applicable; and corrective actions including the eventual replacement of all brackets. The other AD currently requires, for certain airplanes, repetitive inspections for cracking of the balance weight brackets and replacement of any cracked bracket, and provides for an optional terminating action for the repetitive inspections. This proposed AD would require an additional inspection to detect cracks of the balance weight brackets, applicable related investigative and corrective actions, and replacement of a certain balance weight bracket when it has reached its maximum life limit. This proposed AD results from a report indicating that several reworked balance weight brackets have exhibited signs of premature failure. We are proposing this AD to prevent failure of the balance weight brackets of the elevator trim tabs, which could cause loss of the balance weight. This could result in incorrect trim during takeoff and landing, and reduced controllability of the airplane.

The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by the City of Santa Fe for Santa Fe Municipal Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR part 150 are in compliance with applicable requirements.
