Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757-200 and -200CB series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the lap splices at stringer (S)-14R, lower fastener row, are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive external dual frequency eddy current (DFEC) or internal high frequency eddy current (HFEC) inspections of the lap splice, inner skin fasteners, at S-14R, station (STA) 440 through STA 540, and corrective action if necessary. We are proposing this AD to detect and correct cracking of the fuselage skin lap splice. Such cracking could result in reduced structural integrity of the airplane.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. This AD was prompted by a report of significant fuel leakage at the middle position of the left outboard slat. This AD would require modifying the assembly of the slat extension mechanical stop. We are issuing this AD to prevent failure of the assembly of the slat extension mechanical stop, which if not corrected, could lead to a significant fuel leak and result in an uncontained fire.
