Federal Aviation Administration October 19, 2015 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, A330-300, A340-200, A340- 300, A340-500, and A340-600 series airplanes. This AD requires a detailed inspection of the girt installation of each escape slide and slide raft, and corrective action if necessary. This AD was prompted by a report of incorrect installation of the girt panel on passenger doors and an incorrectly installed quick release (girt) bar into the girt panel of the slide raft. We are issuing this AD to detect and correct incorrect girt installation of the escape slide and slide raft, which could prevent slide deployment during an emergency, and result in reduced evacuation capacity from the airplane and possible injury to occupants.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain CFM International S.A. (CFM) CFM56-7B and CFM56-3 turbofan engines. Four headings in the Compliance section are incorrect. This document corrects the errors. In all other respects, the original document remains the same.

This action amends Class E airspace at Albion Municipal Airport, Albion, NE; Rock County Airport, Bassett, NE; and Jim Kelly Field Airport, Lexington, NE. Decommissioning of the non-directional radio beacons (NDBs) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports. Also, the geographic coordinates are being updated for Rock County Airport and Jim Kelly Field Airport.

This action amends Class E airspace at Tekamah Municipal Airport, Tekamah, NE. A Class E extension is no longer required due to the decommissioning of the Tekamah VHF Omni-directional radio range (VOR) facility and its associated standard instrument approach procedures (SIAPs). This enhances the safety and management of instrument flight rules (IFR) operations at the airport.

We propose to supersede airworthiness directive (AD) 2010-23- 02 for Eurocopter France (now Airbus Helicopters) Model SA-365N, SA- 365N1, AS-365N2, and AS 365 N3 helicopters. AD 2010-23-02 currently requires amending the Limitations section of the Rotorcraft Flight Manual (RFM) to limit the never-exceed velocity (VNE) to 150 Knots Indicated Air Speed (KIAS) and to add a 1,500 ft/minute rate of descent (R/D) limitation beyond 140 KIAS. Since we issued AD 2010-23-02, a design change designated as modification (MOD) 0755B28 improved the dynamic behavior of the horizontal stabilizer such that AD actions are not required. This proposed AD would retain the requirements of AD 2010-23-01 and revise the applicability to exclude helicopters with MOD 0755B28. These proposed actions are intended to exclude certain helicopters from the applicability and restrict the VNE on other helicopters to prevent failure of the horizontal stabilizer and subsequent loss of control of the helicopter.

We propose to supersede Airworthiness Directive (AD) 2014-17- 51, for certain Bombardier, Inc. Model CL-600-2B16 airplanes. AD 2014- 17-51 currently requires inspecting the inboard flap fasteners of the hinge-box forward fitting at Wing Station (WS) 76.50 and WS 127.25 to determine the orientation and condition of the fasteners, as applicable, and replacement or repetitive inspections of the fasteners if necessary. AD 2014-17-51 also provides for optional terminating action for the requirements of that AD. Since we issued AD 2014-17-51, we have determined that additional action is necessary. This proposed AD would also require accomplishment of the previously optional terminating action. We are proposing this AD to detect and correct incorrectly oriented or fractured fasteners, which could result in premature failure of the fasteners attaching the inboard flap hinge-box forward fitting; failure of the fasteners could lead to the detachment of the flap hinge box and the flap surface, and consequent loss of control of the airplane.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318; A319; A320; and A321 series airplanes. This proposed AD was prompted by reports of premature aging of certain passenger chemical oxygen generators that resulted in the generators failing to activate. This proposed AD would require an inspection to determine if certain passenger chemical oxygen generators are installed and replacement of affected passenger chemical oxygen generators. We are proposing this AD to prevent failure of the passenger chemical oxygen generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to the airplane occupants.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes. This proposed AD was prompted by reports of chafing damage due to insufficient clearance on the main landing gear (MLG) stabilizer brace, the nacelle A-frame structure, and the adjacent electrical wiring harnesses. An insufficient fillet radius may also exist on certain airplanes. This proposed AD would require, depending on airplane configuration, an inspection of the nacelle A-frame structure for insufficient fillet radius; an inspection for cracking of affected structure, and rework or repair if necessary, and rework of the nacelle A-frame structure; repetitive inspections of the nacelle A-frame structure and the MLG stabilizer brace for insufficient clearance and damage, and repair if necessary, and rework of the nacelle A-frame structure, which would terminate the repetitive inspections; installation of new stop brackets and a shim on each MLG stabilizer brace assembly; and rework of the electrical wiring harnesses in the nacelle area. We are proposing this AD to detect and correct chafing damage and subsequent premature cracking and fracture of the nacelle A- frame structure, which could result in failure of the MLG stabilizer brace and loss of the MLG down-lock indication, which could adversely affect the safe landing of the airplane.

This action establishes Class E airspace at Tomah, WI. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures at Bloyer Field Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.
