Federal Aviation Administration July 15, 2010 – Federal Register Recent Federal Regulation Documents

This document proposes adopting a new airworthiness directive (AD) for Robinson Model R22, R22 Alpha, R22 Beta, and R22 Mariner helicopters, and Model R44 and R44 II helicopters. The AD would require visually inspecting each tail rotor (T/R) control pedal bearing block support (support) for a crack, measuring the thickness of each uncracked support, installing support safety tabs on certain supports, and replacing supports of a certain thickness during overhaul. This proposal is prompted by two reports of Model R22 helicopters experiencing broken supports during flight, which resulted in the T/R control pedals becoming jammed. The actions specified by the proposed AD are intended to prevent the supports from breaking, which can bind the T/R control pedals, resulting in a reduction of yaw control and subsequent loss of control of the helicopter.

This action will establish Class E airspace at Monterey, CA, to accommodate aircraft using a new Area Navigation (RNAV) Required Navigation Performance (RNP) Standard Instrument Approach Procedures (SIAPs) at Monterey Peninsula Airport. This action will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.

This action will amend Class D and E airspace at Snohomish County Airport (Paine Field), Everett, WA, by updating the geographic coordinates of the airport, and removes the operating hours established by a Notice to Airmen (NOTAM) for the Class E surface area airspace. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at Snohomish County Airport (Paine Field).
