Federal Aviation Administration June 29, 2007 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an obstruction at the cargo compartment fire extinguisher system drier metering unit (DMU) inlet, affecting the system effectiveness and, consequently, making the fire extinguishing capability at those compartments inadequate should a fire erupt. We are issuing this AD to require actions to correct the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas DC-10-30 and DC-10-30F airplanes. This AD requires installing Teflon sleeving around the fuel pump wire harness inside the conduit in the aft supplemental fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
