Nineteenth Meeting of the NextGen Advisory Committee (NAC)
The FAA is issuing this notice to advise the public of a meeting of the Nineteenth Meeting of the NextGen Advisory Committee (NAC).
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This proposed AD was prompted by a report indicating that a portion of the sealant above the engine pylon between the wing skin and the vapor barrier may have been omitted. This proposed AD would require an inspection for missing sealant in the seam on the outside and inside of the engine struts, and corrective actions if necessary. We are proposing this AD to detect and correct missing sealant above the engine pylon between the wing skin and the vapor barrier, which can create an unintended leak path for fuel, potentially draining onto the aft fairing heat shield above the engine and onto hot engine parts or brakes, which could lead to a major ground fire.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters. This AD requires visually inspecting the tail rotor drive shaft assembly (drive shaft) for a crack. This AD was prompted by the discovery of three cracks on the drive shaft of a Model A109S helicopter. The actions of this AD are intended to detect a crack on the drive shaft to prevent failure of the driveshaft, failure of the tail rotor, and subsequent loss of helicopter control.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We are adopting a new airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42-500 and Model ATR72-212A airplanes. This AD was prompted by a report indicating that interference occurred between a Type III Emergency Exit door and the surrounding passenger cabin furnishing during a production check. This AD requires measuring the gap between the Type III Emergency Exit doors and certain overhead stowage compartment fittings; removing certain fittings from the overhead stowage compartments and measuring the gap between the Type III Emergency Exit doors and the overhead stowage compartment hooks, if necessary; re-installing or repairing, as applicable, the Type III Emergency Exit doors; and modifying the overhead stowage compartments. We are issuing this AD to prevent interference between a Type III Emergency Exit door and the overhead stowage compartment fitting installed on the rail, which could result in obstructed opening of a Type III Emergency Exit door during an emergency evacuation.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 90-11-05 for certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4- 203 airplanes and Model A300 B4-600 series airplanes. AD 90-11-05 required repetitive detailed inspections for cracking in the aft hinge brackets of the outer shroud box that is located in the outer wing box, and related investigative and corrective actions if necessary. This new AD changes certain compliance times and adds airplanes to the applicability. This AD was prompted by reports of cracks in the aft hinge brackets of the outer shroud box that is located in the outer wing box, which were found during routine maintenance checks, and our subsequent determination that a change in inspection compliance times is needed. We are issuing this AD to detect and correct cracking of the aft hinge brackets of the outer shroud box; such cracking could affect the structural integrity of the airplane.
