Federal Aviation Administration May 8, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Helicopters
Document Number: 2018-09740
Type: Proposed Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This proposed AD would require inspecting the jettisoning mechanism of the left-hand (LH) and right-hand (RH) cabin sliding plug doors. This proposed AD is prompted by a report that during a scheduled inspection a cabin door failed to jettison. The actions of this proposed AD are intended to correct an unsafe condition on these products.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Document Number: 2018-09731
Type: Proposed Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes. This proposed AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new and/or more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2018-09729
Type: Proposed Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a report of cracking at the fastener holes of the left-hand-side support bracket of the elevator bell crank for the control linkage in the vertical stabilizer. This proposed AD would require an eddy current inspection on certain support brackets of the elevator bell crank for any cracking at the fastener holes, a measurement to confirm that the fastener hole diameters are within tolerance, and replacement with a new support bracket of the elevator bell crank if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2018-09728
Type: Proposed Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt 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), and Model A310 series airplanes. This proposed AD was prompted by a determination that new or more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Textron Aviation Inc. Airplanes
Document Number: 2018-09601
Type: Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We are revising Airworthiness Directive (AD) 2018-03-03 for certain Textron Aviation Inc. Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, 414, 414A, 421, 421A, 421B, 421C, and 425 airplanes. AD 2018-03-03 required repetitively inspecting the left and the right forward lower carry through spar cap for cracks and replacing the carry through spar cap if cracks were found. This AD addresses the same unsafe condition and requires the same actions as AD 2018-03-03, but clarifies the compliance times for the initial inspection of the carry through spar cap. This AD was prompted by several reports of confusion in interpreting the compliance times for the initial inspection of the carry through spar cap. We are issuing this AD to eliminate confusion in interpreting the compliance times for this inspection.
Airworthiness Directives; Learjet, Inc. Airplanes
Document Number: 2018-09600
Type: Proposed Rule
Date: 2018-05-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Learjet, Inc. Models 28, 29, 31, 31A, 35, 35A, 36, 36A, 55, 55B, 55C, and 60 airplanes. This proposed AD was prompted by fatigue cracks initiating in the flap support structure due to repetitive flap loads, which has caused flap nose roller support bracket failure. This proposed AD would require replacement of the flap nose roller fitting, nose roller support bracket, and adjacent rib support structure with more robust components. We are proposing 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: 2018-09566
Type: Rule
Date: 2018-05-08
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.
