Department of Transportation May 21, 2008 – Federal Register Recent Federal Regulation Documents

The Federal Highway Administration (FHWA) is issuing this notice to advise the public that an Environmental Impact Statement (EIS) will be prepared for a proposed highway project in Greene County, Tennessee.

We are adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracking in and around the upper and lower hinge cutouts of the forward entry and forward galley service doorways, and corrective actions if necessary. This AD results from multiple reports of cracks found in the skin, bearstrap, and/or frame outer chord in the hinge cutout areas of the forward entry and forward galley service doorways. We are issuing this AD to detect and correct such cracking, which could result in rapid decompression of the airplane.

We are adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, and -200C series airplanes. This AD requires revising the FAA-approved maintenance inspection program to include inspections that will give no less than the required damage tolerance rating for each structural significant item (SSI), doing repetitive inspections to detect cracks of all SSIs, and repairing cracked structure. This AD results from a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective. We are issuing this AD to maintain the continued structural integrity of the entire fleet of Model 737-100, -200, and -200C series airplanes.

We are adopting a new airworthiness directive (AD) for all Lockheed Model L-1011 series airplanes. This AD requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

In a proposed order published on March 18, 2008, the Federal Aviation Administration (FAA) tentatively identified the parameters of an order that would temporarily limit scheduled flight operations at Newark Liberty International Airport (EWR).\1\ The FAA issued the proposal as a result of persistent congestion and delays at EWR during the peak operating hours, as well as a dramatic projected increase in flight delays at the airport during the summer of 2008 if proposed schedules were implemented as requested by carriers. After evaluating the written comment submitted to the public docket in this matter, the FAA is issuing this final Order, which will take effect at 6 a.m., Eastern Time, on June 20, 2008.

The FAA proposes to establish procedures to address congestion in the New York City area by assigning slots at John F. Kennedy (JFK) and Newark Liberty (Newark) International Airports in a way that allows carriers to respond to market forces to drive efficient airline behavior. This proposal is a companion to a separate rulemaking initiative addressing congestion mitigation at New York's LaGuardia airport. Today's proposal is similar to what we have proposed for LaGuardia airport, but it takes into consideration the characteristics of both JFK and Newark, including the large number of international flights at these airports and our international obligations. The FAA proposes to extend the caps on the operations at the two airports, assign to existing operators the majority of slots at the airports, and create a market by annually auctioning off a limited number of slots in each of the first five years of this rule. The FAA is proposing two alternatives. Under the first alternative, the assignment of slots at JFK and Newark would be conducted through a uniform mechanism. The FAA would auction off a portion of the slots and would use the proceeds to mitigate congestion and delay in the New York City area. Under the second alternative, the same auction procedure would apply at Newark as under the first alternative but at JFK the auction proceeds would go to the carrier holding the slot rather than to the FAA. For both alternatives, this proposal also contains provisions for minimum usage, capping unscheduled operations, and withdrawal for operational need. The FAA proposes to sunset the rule in ten years.
