Federal Aviation Administration December 29, 2011 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) is considering a proposal to change a portion of airport land from aeronautical use to non-aeronautical use and to authorize the sale of the airport property. The proposal consists of all or portions of Parcels 209A, 213, 217, 218, 219, 220, 221, 314, 315, 401, 402, 404, 406, 407, 408, 409, 410, 411, 412, 413, 414, and 416, totaling 605.3 acres. Presently the land is vacant and used as open land for control of FAR Part 77 surfaces and compatible land use and is not needed for aeronautical use, as shown on the Airport Layout Plan. The Parcels were acquired without Federal participation. It is the intent of the DuPage Airport Authority, as owner and operator of the DuPage Airport (DPA) to sell the aforementioned Parcels (605.3 Acres) in fee to the DuPage County (22.7 acres for Kress Creek floodplain control), the City of West Chicago (37.7 acres for the ownership and maintenance of existing roadways), the Illinois Department of Transportation (11.3 acres for the improvement of State Route 38), and to private entities (533.6 acres for corporate/industrial development). This notice announces that the FAA is considering the proposal to authorize the disposal of the subject airport property at the DuPage Airport, West Chicago, IL. Approval does not constitute a commitment by the FAA to financially assist in disposal of the subject airport property nor a determination that all measures covered by the program are eligible for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of Title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.

We are revising an earlier proposed airworthiness directive (AD) for Goodrich Evacuation Systems approved under Technical Standard Order (TSO) TSO-C69b and installed on Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-500 and -600 series airplanes. That NPRM proposed to supersede an existing AD. That NPRM proposed inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, replacing certain pressure relief valves, and adding airplanes to the applicability. That NPRM was prompted by reports that during workshop testing, certain pressure relief valves, which were required by the existing AD, did not seal and allowed the pressure in certain slides/rafts to fall below the minimum raft mode pressure for the unit. This action revises that NPRM by adding certain airplanes to the applicability. We are proposing this supplemental NPRM to correct the unsafe condition on these products. 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 proposed changes.

Pursuant to Section 10(a)(2) of the Federal Advisory Committee Act (Pub. L. 92-463, 5 U.S.C. App. 2), notice is hereby given of a teleconference of the Commercial Space Transportation Advisory Committee (COMSTAC) Risk Management Working Group. The teleconference will take place on Tuesday, January 24, 2012, starting at 1:30 p.m. Eastern Standard Time. Individuals who plan to participate should contact Susan Lender, Designated Federal Officer (DFO), (the Contact Person listed below) by phone or email for the teleconference call in number. The National Aeronautics and Space Administration (NASA) and the FAA Office of Commercial Space Transportation (AST) have agreed to prepare a study on the availability of commercial insurance sufficient to meet the needs of NASA's Commercial Crew Program commercial providers for missions transporting NASA astronauts to and from the International Space Station. NASA's Commercial Crew Program requested this study (via a signed memorandum of understanding with the FAA AST) be conducted by AST because of its knowledge and resources in the commercial space industry. The purpose of the teleconference is to: 1. Brief the COMSTAC Risk Management Working Group on the study, 2. Request assistance from the working group in preparing a response to NASA, and 3. Respond to any questions from the working group on the nature of this task. Interested members of the public may submit relevant written statements for the COMSTAC members to consider under the advisory process. Statements may concern the issues mentioned above or additional issues that may be relevant for the U.S. commercial space transportation industry. Interested parties wishing to submit written statements should contact Susan Lender, DFO, (the Contact Person listed below) in writing (mail or email) by January 17, 2012, so that the information can be made available to COMSTAC members for their review and consideration before the January 24, 2012, teleconference. Written statements should be supplied in the following formats: one hard copy with original signature or one electronic copy via email. This notice will be posted on the FAA Web site at https:// www.faa.gov/go/ast. Individuals who plan to participate and need special assistance should inform the Contact Person listed below in advance of the meeting.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 freighter series airplanes; Model A330- 200 and -300 series airplanes; and Model A340-200 and -300 series airplanes. This proposed AD was prompted by a report of corrosion found on the main fitting of the nose landing gear (NLG) leg in the vicinity of the dowel pin bushes retaining the lower steering flange. This proposed AD would require modifying the NLG main fitting by adding primer paint to the cadmium around the dowel bush holes. We are proposing this AD to prevent NLG main fitting rupture, which could result in an NLG collapse.

We propose to adopt a new airworthiness directive (AD) for all Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. This proposed AD was prompted by reports of hydraulic accumulator failure. This proposed AD would require replacing certain hydraulic accumulators with stainless steel hydraulic accumulators, and structural modifications in the nose landing gear bay. We are proposing this AD to prevent failure of hydraulic accumulators, which may result in damage to the airplane and injury to occupants.
