Federal Aviation Administration March 9, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Airplanes
Document Number: 2018-04727
Type: Proposed Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318-111 and -112 airplanes, Model A319-111, -112, -113, - 114, and -115 airplanes, Model A320-211, -212, -214, and -216 airplanes, and Model A321-111, -112, -211, -212, and -213 airplanes. This proposed AD was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. This proposed AD would require modifying and re-identifying the aft engine mount assemblies. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2018-04720
Type: Proposed Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2016-24- 03, which applies to certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2016-24-03 requires repetitive detailed inspections of barrel nuts and cradles, a check of the bolt torque of the preload indicating (PLI) washers, and corrective actions if necessary. Since we issued AD 2016-24-03, the manufacturer has developed a modification that, when incorporated, terminates the repetitive inspections. This proposed AD would require modifying the airplane by installing a sealing disk to a certain location and replacing certain barrel nuts. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2018-04719
Type: Proposed Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2013-11- 12, which applies to certain Bombardier, Inc., Model BD-100-1A10 airplanes. AD 2013-11-12 requires inspecting for the correct serial number of a certain hydraulic system accumulator, and replacing affected hydraulic system accumulators with new or serviceable accumulators. Since we issued AD 2013-11-12, we have determined that certain other hydraulic system accumulators must be modified or replaced and life limits must be added. This proposed AD would expand the applicability and require modifying or replacing certain hydraulic brake system accumulators. This proposed AD would also require revising the maintenance or inspection program to add life limits for the accumulators. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2018-04647
Type: Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD requires inspecting the tail rotor (T/R) flapping hinge link (hinge) and reporting the results. This AD is prompted by a report of a damaged flapping hinge link. The actions of this AD are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2018-04646
Type: Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A320-214, -251N, and -271N airplanes. This AD requires an inspection for any damaged bolt and nut in each cargo fire extinguishing bottle installation, and replacement of any damaged bolt and nut. This AD was prompted by a report that a dynamometric key, previously used for installing the cargo fire extinguishing bottle system, was out of tolerance. As a result, an incorrect torque value may have been applied to the bolts maintaining the fire extinguishing bottles in place. We are issuing this AD to address the unsafe condition on these products.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
Document Number: 2018-04584
Type: Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
Document Number: 2018-04583
Type: Rule
Date: 2018-03-09
Agency: Federal Aviation Administration, Department of Transportation
This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
