## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This AD requires revising the Limitations section of the airplane flight manual to prohibit resetting a tripped circuit breaker for a fuel pump. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prohibit the resetting of a tripped circuit breaker for a fuel pump, which could allow an electrical fault to override the protective features of the circuit breaker, and could result in sparks inside the fuel tank, ignition of fuel vapors, and consequent fire or explosion.
