Airworthiness Directives; MD Helicopters, Inc. Model MD900 Helicopters
This amendment supersedes an existing airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 helicopters, that currently requires reducing the life limit of certain Notar fan system tension-torsion (TT) straps. That existing AD also requires, at a specified time interval, removing each affected TT strap from the helicopter, doing a visual and X-ray inspection, and replacing any unairworthy part before further flight. This amendment requires the same actions as the existing AD, but also requires revising the life limit on the component history card or equivalent record and doing repetitive visual and X-ray inspections, and removes reporting requirements. This amendment is prompted by two in-flight TT strap failures. The actions specified by this AD are intended to prevent failure of a TT strap, loss of directional control, and subsequent loss of control of the helicopter.
Congestion Management Rule for LaGuardia Airport
The FAA is proposing a rule to address the potential for increased congestion and delay at New York's LaGuardia Airport (LaGuardia) when the High Density Rule (HDR) expires there on January 1, 2007. The rule, if adopted, would establish an operational limit on the number of aircraft landing and taking off at the airport. To offset the effect of this limit, the proposed rule would increase utilization of the airport by encouraging the use of larger aircraft through implementing an airport-wide, average aircraft size requirement designed to increase the number of passengers that may use the airport within the overall proposed operational limits.
Amendment to Class D Airspace; Provo, UT
This action amends the Class D airspace area at Provo, UT. A review of the legal description revealed that it does not reflect the current airport reference point (ARP) for Provo Municipal Airport.
Amendment to Class E Airspace; Provo, UT
This action corrects an error in the airport reference point (ARP) for Provo Municipal Airport, Provo, UT, in the final rule that was published in the Federal Register on August 1, 2006, (71 FR 43355), Docket No. FAA-2006-24234; Airspace Docket No. 06-AWP-5. In addition, corrections are made to change FAA Order 7400.9O to FAA Order 7400.9N, amending its date in two references to September 1, 2005, effective September 15, 2005; and make two editorial changes, replacing the word attends with amends in the Summary, and Class D to Class E in the legal description.
Congestion and Delay Reduction at Chicago O'Hare International Airport
The FAA is adopting regulations to address persistent flight delays from overscheduling at O'Hare International Airport (O'Hare). This final rule is intended to be an interim measure only, and the FAA anticipates that the rule will yield to longer term solutions to traffic congestion at the airport. Such solutions include plans by the City of Chicago to modernize the airport and reduce levels of delay, both in the medium term and long term. For this reason, the final rule includes provisions allowing for the limits it imposes to be gradually relaxed, and in any event the regulation will sunset in 2008.
