We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000EX airplanes. This AD was prompted by a quality review of delivered airplanes, which identified a manufacturing deficiency of some engine air inlet anti-ice ``piccolo'' tubes. This AD requires inspecting each anti-ice ``piccolo'' tube assembly of certain engine air inlets for discrepancies, and doing corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of cracking in the webs of the stub beams at certain fuselage stations. These cracks are the result of fatigue caused by cyclical loading from pressurization, wing loads, and landing loads. This AD requires repetitive inspections for cracking of the webs of the stub beams at certain fuselage stations, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
