Federal Aviation Administration June 2012 – Federal Register Recent Federal Regulation Documents

This document proposes to adopt a new airworthiness directive (AD) for Schweizer Aircraft Corporation (Schweizer) Model 269D and Model 269D Configuration A helicopters. The type certificate for these models is currently held by Sikorsky Aircraft Corporation (Sikorsky). This proposal is prompted by reports of loose horizontal stabilizers and cracks in the stabilizer-support structure for the extruded tailboom. The AD would require inspecting the aft fuselage assembly in the area around the attachment point of the horizontal stabilizer, including the paint, for a crack. This AD also would require inspecting the tailboom interior support structure, and if necessary, installing an inspection panel kit in the aft fuselage assembly, and installing doublers in the stabilizer support brackets. The actions specified by the proposed AD are intended to prevent separation of the horizontal stabilizer from the helicopter and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for Cessna 206, 207, and 210 airplanes with Hartzell Engine Technologies (HET) turbochargers, part numbers (P/Ns) 406610-0005 and 406610-9005, installed. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires removing the affected turbochargers from service before further flight. This AD was prompted by a report of an HET turbocharger causing an engine in-flight power rollback. We are issuing this AD to prevent turbocharger bearing seizure, failed turbocharger components, and damage to the airplane.

This action amends Class E Airspace at Orlando, FL, as new Standard Instrument Approach Procedures have been developed at Orlando Executive Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System. This action also makes a minor adjustment to the geographic coordinates of Orlando Executive Airport, Orlando International Airport, and Kissimmee Municipal Airport.

This action proposes to establish Class E airspace at Fort Morgan, CO. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedure at Fort Morgan Municipal Airport, Fort Morgan, CO. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport.

The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR part 158). This notice is published pursuant to paragraph d of Sec. 158.29.

We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. That AD currently requires replacing the separation link assembly on the applicable entry and service doors with an improved separation link assembly, and doing related investigative and corrective actions if necessary. This new AD adds an airplane to the applicability and removes certain other airplanes. This AD was prompted by a report that an additional airplane is subject to the unsafe condition. We are issuing this AD to prevent failure of an entry or service door to open fully in the event of an emergency evacuation, which could impede exit from the airplane. This condition could result in injury to passengers or crewmembers.

We propose to supersede two existing airworthiness directives (AD) that apply to certain Fokker Services B.V. Model F.28 Mark 0100 airplanes. The first existing AD currently requires removing the actuator from the fuel-balance transfer-valve (FBTV) and installing a locking device on the FBTV. The second existing AD currently requires inspecting to verify that the position indicator of the FBTV is in the closed position and deactivating the fuel-balance transfer-system. Since we issued those ADs, we have received reports that the FBTV was inadvertently reactivated after required de-activation measures were undone. This proposed AD would require installing an FBTV locking device. We are proposing this AD to prevent fuel starvation and consequently a double-engine flameout, possibly resulting in a forced landing, damage to the airplane, and injury to occupants.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for a new information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on August 4, 2011, vol. 76, no. 150, page 47287-47288. The FAA intends to collect safety-related data regarding the voluntary implementation of Commercial Aviation Safety Team (CAST) safety enhancements (SEs) from certificate holders conducting operations under 14 CFR Part 121 and Parts 121/135.

This action modifies Class D and Class E airspace at Bellingham, WA, to accommodate aircraft departing and arriving under Instrument Flight Rules (IFR) at Bellingham International Airport. This action, initiated by the biennial review of the Bellingham airspace area, enhances the safety and management of aircraft operations at the airport.

We are superseding an existing airworthiness directive (AD) for certain Bombardier Inc. Model CL-215-1A10 and CL-215-6B11 (CL-215T Variant) airplanes. That AD currently requires repetitive inspections to detect cracking of the lower cap of the wing front and rear spars at wing station (WS) 51.00, and the wing lower skin. Additional actions, if cracking is found, include reworking the lower cap of the front or rear spar, inspecting for cracking, and repairing any cracking. The existing AD also requires reporting inspection results. This new AD requires extending the inspection area of the rear spar lower cap from WS 51.00 to WS 49.50 and modifying the ultrasonic inspection calibration procedure. This AD was prompted by reports of cracking found outside the inspection area. We are issuing this AD to detect and correct cracking of the lower caps of the wing front and rear spars, and lower wing skin, which could result in reduced structural integrity of the airplane.

We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland GMBH (ECD) Model MBB-BK 117 C-1 and C-2 helicopters. This AD requires installing a placard that corresponds to the maximum permissible flight altitude, amending the Rotorcraft Flight Manual (RFM) to revise the maximum permissible operating altitude, and inserting revised performance charts into the RFM. This AD also requires a repetitive maintenance ``MAX N1 CHECK'' to determine the appropriate maximum altitudes. This AD also requires, if the engine or a Fuel Control Unit (FCU) or module 2 or 3 is replaced, repeating the maintenance ``MAX N1 CHECK.'' Finally, this AD specifies that modifying both engines would provide terminating action for the AD requirements. This AD was prompted by the failure of a ``few'' engines to reach the specified one-engine-inoperative (OEI) rating at altitudes above 10,000 feet. The actions of this AD are intended to prevent flights at altitudes where the full OEI engine power cannot be reached and subsequent loss of control of the helicopter if an OEI operation is required.
