Airworthiness Directives; Boeing Model 737-200, -200C, -300, -400, -500, -600, -700, -700C, -800, and -900 Series Airplanes

摘要

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-200, -200C, -300, -400, -500, -600, -700, - 700C, -800, and -900 series airplanes. This AD requires a one-time detailed inspection for discrepancies of the secondary fuel vapor barrier of the wing center section, and related investigative/ corrective actions if necessary. This AD is prompted by reports that the secondary fuel vapor barrier was not applied correctly to, or was missing from, certain areas of the wing center section. We are issuing this AD to prevent fuel or fuel vapors from leaking into the cargo or passenger compartments and coming into contact with a possible ignition source, which could result in fire or explosion.
