Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. This proposed AD was prompted by a report of an engine fire caused by a leak in the fuel pump inlet hose. This proposed AD would require inspecting the fuel hose assembly and the turbocharger support assembly for proper clearance between them, inspecting each assembly for any sign of damage, and making any necessary repairs or replacements. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Agusta S.p.A Helicopters (Type Certificate Currently Held by AgustaWestland S.p.A) (Agusta)
We are adopting a new airworthiness directive (AD) for Agusta Model A109A, A109A II, A109C, A109E, A109K2, A109S, AW109SP, A119, and AW119 MKII helicopters. This AD requires inspecting and replacing certain part-numbered main rotor swashplate support nuts. This AD is prompted by a report of two cracked nuts found on an A109S helicopter. These actions are intended to detect a cracked nut and prevent failure of the main rotor system, and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) (Airbus Helicopters) Helicopters
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP helicopters to require measuring the operating load of the cockpit fuel shut-off controls and replacing the tangential gearbox if the operating load threshold is exceeded. This AD was prompted by the jamming of the left-hand (LH) side of the fuel shut-off and general cut-off controls (controls). The actions of this AD are intended to prevent the jamming of the controls so that a pilot can shut down an engine during an engine fire or during an emergency landing.
Special Conditions: Bombardier Aerospace, Models BD-500-1A10 and BD-500-1A11 Series Airplanes; Tire Debris Impacts to Fuel Tanks
This action proposes special conditions for the Bombardier Aerospace Models BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have a novel or unusual design feature associated with the use of carbon fiber reinforced plastic (CFRP) for most of the wing fuel tank structure, which, when impacted by tire debris, may resist penetration or rupture differently from aluminum wing skins. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes. This AD was prompted by reports of smoke or flames in the passenger cabin of various transport category airplanes related to the wiring for the passenger cabin in-flight entertainment (IFE) system, cabin lighting, and passenger seats. This AD requires installing wiring and making changes to certain electrical load management system (ELMS) panels and other concurrent requirements to ensure the flightcrew is able to turn off electrical power to the IFE systems and other non-essential electrical systems through one or two switches in the flight deck in the event of smoke or flames. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew's inability to turn off electrical power to the IFE system and other non-essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non- normal or emergency situation, and consequent loss of control of the airplane.
Airworthiness Directives; Airplanes Originally Manufactured by Lockheed for the Military as Model P-3A and P3A Airplanes
We are adopting a new airworthiness directive (AD) for certain airplanes originally manufactured by Lockheed Martin Aeronautics Company for the military as Model P-3A or P3A airplanes. This AD was prompted by a determination that the existing maintenance or inspection program must be revised to address fatigue cracking of the airplane. This AD requires revising the maintenance or inspection program, as applicable, to incorporate certain limitations. We are issuing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the airplane.
