Special Conditions: Dassault Aviation Model Falcon 5X Airplanes; Non-Rechargeable Lithium Battery Installations
These special conditions are issued for non-rechargeable lithium battery installations on the Dassault Aviation (Dassault) Model Falcon 5X airplane. Non-rechargeable lithium batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. 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.
Special Conditions: Gulfstream Aerospace Corporation, Gulfstream GVI Airplane; Non-Rechargeable Lithium Battery Installations
This document corrects errors that appeared in Docket No. FAA- 2015-4279, Special Conditions No. 25-612-SC, which was published in the Federal Register on April 22, 2016. The errors are incorrect title 14, Code of Federal Regulations section citations in two locations in the final special conditions document.
Special Conditions: Airbus Model A330-841 and A330-941 New Engine Option (A330neo) Airplanes; Use of High-Incidence Protection and Alpha-Floor Systems
These special conditions are issued for the Airbus Model A330- 841 and A330-941 New Engine Option (A330neo) airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport- category airplanes. This design feature is a high-incidence protection system that limits the angle of attack (AOA) at which the airplane can be flown during normal low-speed operations, and that the flightcrew cannot override. 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; Airbus Helicopters
We are superseding Airworthiness Directive (AD) 2015-22-53 for Airbus Helicopters Model AS350B3 helicopters. AD 2015-22-53 required revising the rotorcraft flight manual (RFM) to perform the yaw load compensator check after rotor shut-down and to state that the yaw servo hydraulic switch must be in the ``ON'' position before taking off. Since we issued AD 2015-22-53, Airbus Helicopters developed a modification of the ACCU TST switch. This new AD retains the requirements of AD 2015-22-53 and requires modifying the yaw servo hydraulic switch (collective switch) and replacing the ACCU TST button. The actions of this AD are intended to address an unsafe condition on these products.
Airworthiness Directives; DG Flugzeugbau GmbH Gliders
We propose to supersede Airworthiness Directive (AD) 2017-08- 09 for DG Flugzeugbau GmbH Models DG-500MB gliders that are equipped with a Solo 2625 02 engine modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Technische Mitteilung (TM)/Service Bulletin (SB) 4600-3 ``Fuel Injection System'' and identified as Solo 2625 02i. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 the potential of an in-flight shut-down and engine fire due to failure of the connecting stud for the two fuel injector mounts of the engine redundancy system on gliders equipped with a Solo 2625 02i engine. This proposed AD adds the DG Flugzeugbau GmbH Model DG- 1000M glider equipped with Solo 2625 02i engines to the applicability. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc.
We propose to supersede Airworthiness Directive (AD) 2014-02- 01, which applies to certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2014-02-01 requires repetitive inspections of the rudder travel limiter (RTL) return springs and primary actuator, and corrective actions if necessary; and replacement of certain RTL return springs. Since we issued AD 2014-02-01, we received reports that when installing the RTL return springs, the RTL limiter arm assembly lug can become deformed. This proposed AD would require an inspection of the RTL return springs for signs of chafing; an inspection of the casing of the primary actuator for signs of chafing or missing paint; replacement of the RTL return springs; and an inspection of the lugs of the RTL limiter arm assembly for cracks, and modification or replacement, as applicable; and applicable corrective actions. This proposed AD would also add airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes) airplanes. This AD was prompted by a revision of certain airworthiness limitation item (ALI) documents, which require more restrictive maintenance requirements and airworthiness limitations. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
