Federal Aviation Administration April 16, 2007 – Federal Register Recent Federal Regulation Documents

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums 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, addition of new obstacles, or changes in 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.

The FAA is revising an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211-22B series, RB211-524B, -524C2, -524D4, -524G2, -524G3, and -524H series, and RB211-535C and -535E series turbofan engines with high pressure compressor (HPC) stage 3 disc assemblies, part numbers (P/Ns) LK46210, LK58278, LK67634, LK76036, UL11706, UL15358, UL22577, UL22578, and UL24738 installed. That AD currently requires removing from service certain disc assemblies before they reach their full published life if not modified with anticorrosion protection. This AD requires the same actions but relaxes the removal compliance time for certain disc assemblies that have a record of detailed inspection. This AD results from the FAA allowing certain affected disc assemblies that entered into service before 1990 that have a record of detailed inspections, to remain in service for a longer period than the previous AD allowed. We are issuing this AD to relax the compliance time for certain disc assemblies and track the disc life based on a detailed inspection rather than by its entry into service date, while continuing to prevent corrosion-induced uncontained disc assembly failure, resulting in damage to the airplane.

This notice proposes special conditions for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The architecture of the Boeing Model 787-8 systems and networks allows access to external systems and networks, including the public Internet. On-board wired and wireless devices may also have access to parts of the airplane's digital systems that provide flight critical functions. These new connectivity capabilities may result in security vulnerabilities to the airplane's critical systems. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection and security of airplane systems and data networks against unauthorized access. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

The FAA hereby provides notice of intent to release certain airport properties 7.742 acres at the Kendall Tamiami Executive Airport, Miami, FL from the conditions, reservations, and restrictions as contained in a FAAP agreement between the FAA and the County of Miami-Dade, dated June 4, 1965. The release of property will allow the County of Miami-Dade to dispose of the property for other than aeronautical purposes. The property is located in the South 35ft. of Section 16, Township 55 South, Range 39 East, Miami-Dade County, Florida; less the West 185ft. thereof and the South 35ft. of the West \1/4\ of Section 15, Township 55 South, Range 39 East, Miami-Dade County, Florida. The parcel is currently designated as non-aeronautical use. The property will be disposed of for the purpose of constructing the realignment of proposed SW. 157th Ave. The fair market value of the property has been determined by appraisal to be $4,350,000. The airport will receive fair market value for the property, which will be subsequently reinvested in another eligible airport improvement project or used for operation and maintenance of the Kendall Tamiami Executive Airport. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Miami Dade Aviation Department Offices and the FAA Airports District Office.
