The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 224: Airport Security Access Control Systems.

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 Space Transportation Operations Working Group (STOWG) of the Commercial Space Transportation Advisory Committee (COMSTAC). The teleconference will take place on Wednesday, December 8, 2010, starting at 11 a.m. Eastern Standard Time. Individuals who plan to participate should contact Susan Lender, DFO, (the Contact Person listed below) by phone or e-mail for the teleconference call in number. The proposed agenda for this teleconference is to continue the discussion started during the October 6, 2010, working group meeting. This discussion will include looking at the orbital debris questions asked by the FAA; continuing the group's review of the Concept of Operation for Global Space Vehicle Debris Threat Management Report, and updating the list of top issues that should require the working group's attention. Interested members of the public may submit relevant written statements for the COMSTAC working group members to consider under the advisory process. Statements may concern the issues and agenda items 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 e- mail) by December 1, 2010, so that the information can be made available to COMSTAC members for their review and consideration before the December 8, 2010, teleconference. Written statements should be supplied in the following formats: One hard copy with original signature or one electronic copy via e-mail. An agenda will be posted on the FAA Web site at https://www.faa.gov/ go/ast.

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2010-19-51, which was sent previously to all known U.S. owners and operators of the specified model Bell Helicopter Textron Canada (Bell) helicopters by individual letters. This AD requires inspecting parts of the main rotor hydraulic servo actuator (servo actuator) for certain conditions and replacing any unairworthy parts before further flight. This AD is prompted by a collective servo actuator malfunction and a subsequent investigation that revealed the output piston rod assembly (piston rod) had fractured at the threaded end because of stress corrosion cracking. Also, during the investigation of that servo actuator malfunction, a nonconforming grind relief was discovered on a separate piston rod. The actions specified by this AD are intended to detect corrosion or a nonconforming piston rod that, if not detected and corrected, could result in failure of the piston rod, failure of the servo actuator, and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires doing a one-time general visual inspection for a keyway in two fuel tank access door cutouts, and related investigative and corrective actions if necessary. This AD was prompted by reports of cracks emanating from the keyway of the fuel tank access hole. We are issuing this AD to detect and correct such cracking, which could result in the loss of the lower wing skin load path and consequent structural failure of the wing.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
