Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Airworthiness Directives; Airbus Helicopters, Inc. (Previously Eurocopter France) Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters, Inc. (previously Eurocopter France) Model AS355E, AS355F, AS355F1, and AS355F2 helicopters with a Fueltron flowmeter installed. This proposed AD would require removing each flowmeter, replacing the fuel system hoses, and disabling the electrical connections for the flowmeter installation. This proposed AD is prompted by a report of particle contamination creating an obstruction in a flowmeter which resulted in an uncontrolled flame-out of the engine. The proposed actions are intended to prevent obstruction of the fuel supply to the flowmeter, which could result in engine flame-out and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada (Bell) Helicopters
We propose to supersede airworthiness directive (AD) 2001-13- 51 for Bell Model 206L-4, 407, and 427 helicopters. AD 2001-13-51 currently requires inspecting certain driveshafts for a crack, a loose bolt or nut, or red powder residue and replacing a driveshaft if there is a crack, a loose bolt or nut, or red powder residue. AD 2001-13-51 also requires notifying the FAA within 10 days if a crack is found in the driveshaft. Since we issued AD 2001-13-51, the Model 429 helicopter has been certificated, and the reporting requirement is no longer necessary. This proposed AD would retain the inspection requirement of AD 2001-13-51, expand the applicability to include the Model 429 helicopter, and remove the reporting requirement. These proposed actions are intended to prevent failure of a driveshaft, loss of drive to the main rotor system, and a subsequent emergency landing.
Airworthiness Directives; Various de Havilland Airplanes
We propose to adopt a new airworthiness directive (AD) for all Harry E. Williams de Havilland Model DH 82A airplanes, all Cliff Robertson de Havilland Model DH 82A airplanes, and all de Havilland Model DH 83 airplanes. This proposed AD was prompted by reports of structural failure of the attachment of the wing to the fuselage that resulted from failed lateral fuselage tie rods. This proposed AD would require inspecting the aircraft maintenance records to determine the date of installation or the date of last replacement of the lateral fuselage tie rods. This proposed AD would also require repetitively replacing all lateral fuselage tie rods and attaching nuts at a specified life limit interval. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON and FAN JET FALCON SERIES C, D, E, F, and G airplanes. This proposed AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce changes to the maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate a new airworthiness limitations section. We are proposing this AD to prevent reduced structural integrity of the airplane.
Office of Commercial Space Transportation; Notice of Availability of the Final Environmental Assessment (EA) for the Midland International Air and Space Port, City of Midland, Midland County, Texas, and Finding of No Significant Impact (FONSI)
In accordance with the National Environmental Policy Act of 1969, as amended (NEPA; 42 U.S.C. 4321, et seq.), Council on Environmental Quality NEPA implementing regulations (40 CFR Parts 1500- 1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of the Final EA for the Midland International Air and Space Port, City of Midland, Midland County, Texas, and FONSI.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters
The FAA is revising airworthiness directive (AD) 2014-07-04 that published in the Federal Register to correct certain errors. AD 2014-07-04 applied to certain Sikorsky Model S-92A helicopters. The range of serial numbers in the Applicability section and a reference to the service information in the Required Actions section of the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.
Amendment of Air Traffic Service (ATS) Routes; Northeast ME
This action modifies VOR Federal airways V-93, V-314, and V- 471; and RNAV route T-295 in northeastern Maine due to the scheduled decommissioning of the Princeton, ME, VOR facility. In addition, an analysis of the airway structure in that area found that some segments of the affected routes are rarely utilized and are therefore being removed.
Special Conditions: AgustaWestland, AW189; Use of 30-Minute All Engines Operating (AEO) Power Rating
These special conditions are issued for the AgustaWestland Model AW189 helicopter. This model helicopter will have the novel or unusual design feature of a 30-minute all engines operating (AEO) power rating, generally intended to be used for hovering at increased power for search and rescue missions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by reports of a manufacturing defect in the charge indicator on fire extinguisher bottles. This AD requires repetitive weighing of fire extinguisher bottles having a certain part number, and eventual replacement of those bottles to terminate the repetitive weighing. We are issuing this AD to detect and correct a dormant failure in the fire suppression system, which could result in the inability to put out a fire in an engine, auxiliary power unit, or rear compartment.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and 315 airplanes. This AD was prompted by reports of dual alternating current (AC) generator failure during flight. The failure was attributed to wire chafing along the wing lower flap shroud. This AD requires revising the maintenance program to incorporate certain tasks for the electrical wiring interconnection system inspection program. We are issuing this AD to prevent failure of both AC generators due to wire chafing, which could result in loss of power to the anti-icing heaters for the elevator horn, engine inlet, and propeller, and consequent ice accumulation in these areas, which could adversely affect the controllability of the airplane.
Airworthiness Directives; DG Flugzeugbau GmbH Gliders
We are revising an airworthiness directive (AD) 2013-22-14 for any DG Flugzeugbau GmbH Model DG-1000T glider equipped with a Solo Kleinmotoren Model 2350 C engine. 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 engine shaft failure and consequent propeller detachment. We are issuing this AD to require actions to address the unsafe condition on these products.
