Federal Aviation Administration April 21, 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A320 series airplanes. This proposed AD would require installing insulator and cable ties to the electrical cables of the S routes at the gaps in the raceway in the wing trailing edge and the wing tip and wing root areas. This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent injection of high voltage current into the low voltage wiring that passes through the fuel tanks, which could result in a possible fuel tank explosion.

This notice announces the issuance of change 1 to Advisory Circular (AC) 23-21, Airworthiness Compliance Checklists Used to Substantiate Major Alterations for Small Airplanes. The most significant change is a revision in all locations to the signature required so the aircraft may be returned to service after major alteration. The Aviation Safety Inspector in the Flight Standards District Office must now sign instead of an Airframe and Powerplant mechanic. Other changes were minor.

On October 1, 1999, the FAA amended the regulations governing takeoff and landing slots and slot allocation procedures at certain High Density Traffic Airports as a result of the ``Open Transborder'' Agreement between the Government of the United States and the Government of Canada. One element of this final rule established that the deadline for submission of requests for international slots will be published in a Federal Register notice for each scheduling season. The purpose of the amendment is for the FAA deadline for international slots requests to coincide with the International Air Transport Association deadline for submission of international requests. In accordance with this amendment, the FAA announces in this notice that the deadline for submitting requests for international slots at John F. Kennedy International Airport (JFK) for allocation under 14 CFR 93.217 is May 12, 2005. Additionally, the FAA has designated Chicago's O'Hare International Airport (O'Hare) as a Level 2, Schedules Facilitated Airport under the IATA Guidelines. As such, the FAA requests carriers intening to conduct international service to O'Hare submit their intended schedules following the same procedures used for submitting requests for slots at JFK.

The FAA proposes to rule and invites public comment on the application to impose and impose and use a PFC at McCarran International Airport, and use the revenue of a PFC at McCarran International Airport, Henderson Executive Airport, and North Las Vegas Airport under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and part 158 of the Federal Aviation Regulations (14 CFR part 158).

The FAA adopts a new airworthiness directive (AD) for certain CENTRAIR 101 series gliders. This AD requires you to replace non- strengthened rudder pedals with reinforced rudder pedals. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this AD to replace the non-strengthened rudder pedals and to prevent failure of the rudder controls. This failure could lead to loss of directional control of the glider.

The FAA adopts a new airworthiness directive (AD) for all Pilatus Aircraft Limited (Pilatus) Models B4-PC11, B4-PC11A, and B4- PC11AF sailplanes. This AD requires you to repetitively inspect the control-column support for cracks and, if any cracks are found, replace the control-column support with a new support. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. We are issuing this AD to detect and correct cracks in the control-column support, which could result in failure of the support. This failure could lead to loss of the primary flight control system.
