Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on May 22, 2007 (72 FR 28597). The error resulted in a confusing compliance time. This AD applies to all Boeing Model 737-100, -200, - 200C, -300, -400, and -500 series airplanes. This AD requires repetitive detailed inspections for damage of the electrical wire and sleeve that run to the fuel boost pump through a conduit in the fuel tank, and arcing damage of the conduit and signs of fuel leakage into the conduit; replacement of the sleeve with a new, smaller-diameter sleeve; and related investigative and corrective actions, as applicable.
