Proposed Inlet Barrier Filter for Rotorcraft Policy Statement
The FAA is announcing a public meeting to gather additional technical input on the subject of installing an engine inlet barrier filter (IBF) on rotorcraft. Input gathered will aid in developing FAA guidance for evaluating engine IBFs installed on rotorcraft. Prior to the public meeting, the FAA previously sought public comments regarding the guidance online.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318-112 airplanes, A319-111, -112, -115, -132, and -133 airplanes, A320-214, -232, and -233 airplanes, and A321-211, - 212, -213, -231, and -232 airplanes. This proposed AD was prompted by a quality control review on the final assembly line, which determined that the wrong aluminum alloy was used to manufacture several structural parts. This proposed AD would require a one-time eddy current conductivity measurements of certain cabin and cargo compartment structural parts to determine if an incorrect aluminum alloy was used, and replacement if necessary. We are proposing this AD to detect and replace structural parts made of incorrect aluminum alloy. This condition could result in reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL- 600-2E25 (Regional Jet Series 1000) airplanes. This AD requires a detailed visual inspection of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair, including applicable related investigative and corrective actions, if necessary. This AD was prompted by reports of loose or missing Hi-Lite fasteners on the upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. We are issuing this AD to detect and correct protruding, loose, or missing fasteners, which could result in structural failure of the engine pylons.
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); and Model A310 series airplanes. This AD was prompted by reports of premature aging of certain passenger chemical oxygen generators that resulted in the generators failing to activate. This AD requires an inspection to determine if certain passenger chemical oxygen generators are installed and replacement of affected passenger chemical oxygen generators. We are issuing this AD to prevent failure of the passenger chemical oxygen generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to airplane occupants.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a report indicating that some operators have inadvertently removed the existing insulation blankets from the upper wing box area. This AD requires inspecting for and replacing missing insulation blankets in the upper wing box area. We are issuing this AD to detect and replace missing insulation blankets from the upper wing box area, which could result in inadequate thermal protection to prevent fuel ignition in the event of an undetected bleed-air leak due to a cracked or ruptured bleed-air duct.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2015-03-06 for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. AD 2015-03-06 required repetitive inspections of the left-hand (LH) and right-hand (RH) wing main landing gear (MLG) rib 6 aft bearing lugs (forward and aft) to detect any cracks on the two lugs, and replacement if necessary. This new AD requires reduction of certain compliance times. This AD was prompted by reports of additional cracking of the MLG rib 6 aft bearing lugs. We are issuing this AD to detect and correct cracking of the MLG rib 6 aft bearing lugs, which could result in collapse of the MLG upon landing.
Airworthiness Directives; Fokker Services B.V. Airplanes
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by accomplishment of a taxi-out checklist which revealed that the elevator movement was partially obstructed due to rotation of the flight control lock adjuster bracket. This AD requires a one-time inspection of the elevator tension control regulator for discrepancies, and corrective actions if necessary. We are issuing this AD to detect and correct discrepancies of the elevator tension control regulators. Such a condition could result in jamming of the elevator mechanism and consequent reduced controllability of the airplane.
