RlN 2120-AA64

Airworthiness Directives; McDonnell Douglas Corporation Model DC~10-30,

DC-10-30F, DC-10-30F (KC-lOA and KDC-10), DC-1O-40, DC-1O-40F, and

MD-10-30F Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Mo

DC-IO-30, DC-IO-30F, DC-10-30F (KC-10A and KDC-IO), DC-IO-40, DC10-40F,an

MD-IO-30F airplanes. This proposed AD would require doing a one-time inspection of

the \vire bundles to determine ifwires touch the upper surface of the center upper

auxiliary fuel tank, and marking the location if necessary; a one-time inspection for

splices and damage of all wire bundles routed above the center upper auxiliary fuel tank

a one-time inspection for damage to the fuel vapor barrier seal and upper surface of the

center upper auxiliary fuel tank; and corrective actions, if necessary. This proposed AD

would also require installing non-metallic barrier/shield sJeeving to the wire harnesses,

new clamps, new attaching hardware, and new extruded channels. This proposed AD

results from fuel system reviews conducted by the manufacturer. We are proposing this rNlTlAUISIC

AD to prevent the potential of ignition sources inside fuel tanks, which, in combination AT~

with flammable fuel vapors, could result in fuel tank explosions and consequent loss of

the airplane.

DATES: We must receive comments on this proposed AD by [INSERT DATE 45

DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].

ACTION: Notice of proposed rulemaking (NPR.M).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Model

DC-IO-JO, DC-IO-JOF, DC-IO-30F (KC-IOA and KDC-IO), DC-IO-40, DC I0-40F, and

MD-IO-30F airplanes. This proposed AD would require doing a one-time inspection of

the wire bundles to determine ifwires touch the upper surface afme center upper

auxiliary fuel tank, and marking the location ifnecessary; a onc-time inspection for

splices and damage of all wire bundles routed above the center upper auxiliary fuel tank;

a one-time inspection for damage to the fuel vapor barrier seal and upper surface of the

center upper auxiliary fuel tank; and corrective actions, if necessary. This proposed AD

would also require installing nonmetallic barrier/shield sleeving to the wire harnesses,

new clamps, new attaching hardware, and new extruded channels. This proposed AD

results from fuel system reviews conducted by the manufacturer. We are proposing this

AD to prevent the potential of ignition sources inside fuel tanks, which, in combination

with flarmriable fuel vapors, could result in fuel tank explosions and consequent loss of

the airplane.
