Airworthiness Directives; SOCATA Airplanes
We are superseding Airworthiness Directive (AD) 99-07-11 for SOCATA Model TBM 700 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks on the outboard hinge fittings. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; M7 Aerospace LLC Airplanes
We are adopting a new airworthiness directive (AD) for certain M7 Aerospace LLC Models SA26-T, SA26-AT, SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-TT, SA227-BC (C-26A), SA227-CC, and SA227-DC (C-26B) airplanes. This AD was prompted by reports of jamming of the aileron control cable chain in the pilot and copilot control columns due to inadequate lubrication and maintenance of the chain. This AD requires repetitively replacing and lubricating the aileron chain, sprocket, and bearings in the control columns. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; AgustaWestland S.p.A. (Type Certificate Previously Held by Agusta S.p.A.) (Agusta) Helicopters
We are adopting a new airworthiness directive (AD) for Agusta Model A109C, A109E, A109K2, and A119 helicopters. This AD requires a recurring visual inspection of the tail rotor (T/R) blade retaining bolts (bolts) for a crack, corrosion, damage, or missing cadmium plating in the central part of the bolt and, depending on findings, a liquid penetrant inspection. This AD also requires replacing a cracked or damaged bolt. This AD was prompted by two reported incidents of cracked bolts. The actions of this AD are intended to detect an unairworthy bolt and prevent failure of a bolt, release of a T/R blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777F series airplanes. This AD was prompted by a report of a fire that originated near the first officer's seat and caused extensive damage to the flight deck. This AD requires replacing the low-pressure oxygen hoses with non-conductive low-pressure oxygen hoses in the stowage box and supernumerary ceiling area. We are issuing this AD to prevent electrical current from passing through an internal, anti-collapse spring of the low-pressure oxygen hose, which can cause the low-pressure oxygen hose to melt or burn and lead to an oxygen-fed fire near the flight deck.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD was prompted by reports of two in-service occurrences on Model 737-400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This AD requires revising the maintenance program to incorporate a revision to the Airworthiness Limitations section of the maintenance planning data document. We are issuing this AD to detect and correct failure of the engine fuel suction feed capability of the fuel system, which could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2000-11-06 for certain The Boeing Company Model 767 airplanes. AD 2000-11-06 required repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/ jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. This new AD requires reducing the initial compliance time and repetitive inspection interval in AD 2000-11-06; mandates a terminating action for the repetitive inspections to eliminate wire damage; removes certain airplanes from the applicability; and requires revising the maintenance program to incorporate changes to the airworthiness limitations section. This AD was prompted by fleet information indicating that the repetitive inspection interval in AD 2000-11-06 is too long, because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. We are issuing this AD to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank.
