Federal Aviation Administration July 20, 2017 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2017-15120
Type: Proposed Rule
Date: 2017-07-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2017-02- 03, which applies to certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. AD 2017-02-03 requires inspection of the plastic potable water coupling, and corrective actions if necessary; installation of new spray shrouds; and inspection of previously installed spray shields, and related investigative and corrective actions if necessary. Since we issued AD 2017-02-03, we have determined that it is necessary to modify a hose assembly installation for certain airplanes, and add airplanes to the applicability. This proposed AD would add airplanes to the applicability and, for certain airplanes, require hose assembly removals and installations. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Helicopters
Document Number: 2017-15031
Type: Rule
Date: 2017-07-20
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Bell Model 212 and Model 412 helicopters. This AD requires replacing certain oil and fuel check valves and prohibits installing them on any helicopter. This AD is prompted by a report of cracked or leaking check valves. These actions are intended to address an unsafe condition on these helicopters.
