Airworthiness Directives; AgustaWestland S.p.A. (Type Certificate Formerly Held by Agusta S.p.A) (Agusta) Helicopters
We propose to supersede an existing airworthiness directive (AD) for Agusta Model AB139 and AW139 helicopters. The existing AD currently requires establishing a revised life limit for each tail rotor blade (blade), updating the helicopter's historical records, repetitively inspecting each blade for a crack, and replacing certain blades. Since we issued that AD, the manufacturer has improved the design of the blades using different materials and established life limits for each newly-designed blade. This proposed AD would expand the applicability to include the newly-designed blades and establish their life limits. This proposed AD would also retain the requirement to inspect each blade for a crack and, if there is a crack, replace each blade with an airworthy blade. The proposed actions are intended to detect a crack in a blade to prevent failure of a blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Pacific Scientific Aviation Services (Pacific Scientific) Seat Restraint System Rotary Buckle Assemblies
We propose to adopt a new airworthiness directive (AD) for the specified Pacific Scientific seat restraint rotary buckle assemblies (buckle). This proposed AD is prompted by several reports of a cracked handle on certain buckles. Testing on these buckles indicates that in some circumstances a load placed on the restraint system prevents a strap from releasing as intended when the buckle is rotated. The proposed actions are intended to replace cracked buckle handles and allow the release of the restraint system strap in an emergency.
Amendment of Class D Airspace; Santa Monica, CA
This action modifies Class D airspace at Santa Monica Municipal Airport, Santa Monica, CA, to accommodate aircraft departing and arriving under Instrument Flight Rules (IFR) at the airport. This action initiated by the biennial review of the Santa Monica Municipal Airport airspace area, and on the results of a study conducted by the Los Angeles Visual Flight Rules (VFR) Task Force, and the Los Angeles Class B Workgroup, enhances the safety and management of aircraft operations at the airport. Adjustments to the geographic coordinates of the airport also are made.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to all Piper Aircraft, Inc. Models PA-31, PA-31-325, and PA-31-350 airplanes. Table 1 of paragraph (g) lists the incorrect model/part number for the Model PA-31-350, tail pipe assembly, top. This document corrects that error. In all other respects, the original document remains the same.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
