We are adopting a new airworthiness directive (AD) for certain Model DC–10–10, DC–10–10F, DC–10– 15, DC–10–30, DC–10–30F (KC–10A and KDC–10), DC–10–40, DC–10–40F, MD–10–10F, MD–10–30F, MD–11, and MD–11F airplanes. This AD requires a one-time installation of electrical bonding jumpers for the fill valve controllers of fuel tanks. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent point-of-contact arcing or filament heating damage in the fuel tanks, which could result in fuel tank explosions and consequent loss of the airplane.

DATES: This AD is effective June 8, 2010.
