Federal Aviation Administration May 12, 2015 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-11351
Type: Proposed Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the lap splices of the aft pressure bulkhead webs are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections for any crack in the aft webs of the radial lap splices of the aft pressure bulkhead, and, if necessary, corrective actions. We are proposing this AD to detect and correct fatigue cracking in the aft webs of the radial lap splices of the aft pressure bulkhead, which could result in reduced structural integrity of the airplane and decompression of the cabin.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Document Number: 2015-11350
Type: Proposed Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-102, -202, -212, and -212A airplanes. This proposed AD was prompted by a report of chafed wires between electrical harnesses. This proposed AD would require inspections for wiring discrepancies, and corrective actions if necessary. We are proposing this AD to detect and correct damaged wiring and incorrect installation of the wiring harness and adjacent air ducts, which could lead to wire harness chafing and arcing, possibly resulting in an on-board fire.
Proposed Amendment of Class E Airspace for the Following Iowa Towns: Audubon, IA; Corning, IA; Cresco, IA; Eagle Grove, IA; Guthrie Center, IA; Hampton, IA; Harlan, IA; Iowa Falls, IA; Knoxville, IA; Oelwein, IA; and Red Oak, IA
Document Number: 2015-11226
Type: Proposed Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend Class E airspace at Audubon County Airport, Audubon, IA; Corning Municipal Airport, Corning, IA; Ellen Church Field Airport, Cresco, IA; Eagle Grove Municipal Airport, Eagle Grove, IA; Guthrie County Regional Airport, Guthrie Center, IA; Hampton Municipal Airport, Hampton, IA; Harlan Municipal Airport, Harlan, IA; Iowa Falls Municipal Airport, Iowa Falls, IA; Knoxville Municipal Airport, Knoxville, IA; Oelwein Municipal Airport, Oelwein, IA; and Red Oak Municipal Airport, Red Oak, IA. Decommissioning of the non-directional radio beacons (NDB) 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.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-11137
Type: Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2004-07-11 for all The Boeing Company Model 767-400ER series airplanes. AD 2004-07-11 requires repetitive high frequency eddy current (HFEC) inspections of the aft lower lugs of the deflection control track of the outboard flap for cracks, and replacement of any cracked deflection control track with a new track assembly. This AD retains those requirements, provides optional terminating action for the repetitive inspections, and adds airplane models to the applicability. This AD was prompted by our determination that additional airplane models require repetitive HFEC inspections of the aft lower lugs of the deflection control track of the outboard flap for cracks, and replacement of any cracked deflection control track with a new track assembly. We are issuing this AD to detect and correct fatigue cracking in the aft lower lug run-out region of the deflection control track, which could result in the loss of the secondary load path for the outboard flap, resulting in the loss of the outboard flap and consequent reduced controllability of the airplane in the event that the primary load path also fails.
Airworthiness Directives; Airbus Airplanes
Document Number: 2015-10181
Type: Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-601, B4-603, and B4-605R airplanes; Model A300 F4- 605R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310- 204 and -304 airplanes; powered by General Electric (GE) Model CF6-80C2 series engines. This AD was prompted by reports of two single-engine flameout events during inclement weather. This AD requires installing a shunt of the rotary selector (introducing an auto-relight function); and, for certain airplanes, a wiring modification to a certain circuit breaker panel. We are issuing this AD to prevent a long engine restart sequence after a non-selection of continuous relight by the crew and a flameout event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.
Airworthiness Directives; GROB-WERKE Airplanes
Document Number: 2015-10071
Type: Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2014-26-04 for certain GROB-WERKE Models G115EG and G120A airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 a defective starter solenoid. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-10069
Type: Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by reports of cracking in the main equipment center (MEC) drip shield and exhaust plenum. This AD requires installing a fiberglass reinforcing overcoat on the MEC drip shield. We are issuing this AD to prevent water penetration into the MEC, which could result in an electrical short and potential loss of several functions essential for safe flight.
Airworthiness Directives; Zodiac Aerotechnics (Formerly Intertechnique Aircraft Systems) Oxygen Mask Regulators
Document Number: 2015-09467
Type: Rule
Date: 2015-05-12
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) oxygen mask regulators. This AD was prompted by a report of a malfunctioning mask having an inflatable harness with a high premature rupture rate due to defective silicon. This AD requires inspecting and replacing defective harnesses with new or modified serviceable units. We are issuing this AD to detect and correct defective harnesses, which could lead, in case of a sudden depressurization event, to a harness rupture, thereby providing inadequate protection against hypoxia and possibly resulting in unconsciousness of the affected flightcrew member and consequent reduced control of the airplane.
