Dassault Model Falcon 2000 Series Airplanes
This amendment supersedes an existing airworthiness directive (AD), applicable to all Dassault Model Falcon 2000 series airplanes, and certain Dassault Model Falcon 900EX and Mystere Falcon 900 series airplanes. That AD currently requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair, if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action if necessary. This amendment removes Model 900EX and Mystere Falcon 900 series airplanes from the applicability of the existing AD. For Model Falcon 2000 series airplanes, this amendment also adds certain repetitive measurements, deletes certain repetitive measurements, and extends the interval for repetitive replacement of certain jackscrews. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent jamming of the flap jackscrews during the approach to landing, which could result in inability to move the flaps or an asymmetric flap condition, and consequent reduced controllability of the airplane.

General Electric Company (GE) CF6-45, -50, -80A, -80C2, and -80E1 Turbofan Engines
This amendment supersedes three existing airworthiness directives (AD's), that are applicable to GE CF6-45, -50, -80A, -80C2, and -80E1 turbofan engines. Those AD's currently require specific handling of the GE CF6 series high pressure compressor rotor (HPCR) stage 3-9 spools during a fluorescent penetrant inspection process, and initial and repetitive ultrasonic and eddy current inspections of certain HPCR stage 3-9 spools for cracks. This amendment removes the AD that requires special handling of the spools during fluorescent- penetrant inspection, and adjusts and combines the initial and repetitive inspection requirements, currently listed in two AD's, into one AD for the HPCR stage 3-9 spool. This amendment aligns repetitive inspection requirements with the more stringent initial inspection requirements mandated by AD 2000-16-12, Amendment 39-11868 (65 FR 50623, August 21, 2000) and terminates AD 95-18-14, Amendment 39-9361 (60 FR 46216, September 6, 1995) that is no longer necessary. The actions specified by this AD are intended to prevent cracks, which can cause separation of the HPCR stage 3-9 spool and possible uncontained engine failure.

Textron Lycoming Division, AVCO Corporation Fuel Injected Reciprocating Engines.
This amendment supersedes two existing airworthiness directives (AD's), that are applicable to certain Textron Lycoming fuel injected reciprocating engines. These AD's currently require inspection, and replacement if necessary, of externally mounted fuel injector fuel lines. These amendments require adding engine series to the applicability that have been identified with the potential for the same problem and necessitate being included in the list of Textron Lycoming fuel injected reciprocating engine series. This amendment is prompted by the need to ensure that the additional Textron Lycoming fuel injected engine series listed in this final rule receive the same inspections as series covered by the current AD's. The actions specified by this AD are intended to prevent failure of the fuel injector fuel lines allowing fuel to spray into the engine compartment, resulting in an engine fire.
