Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This AD requires either that the control circuit breaker of the left fuel pump valve be opened and collared, or that the Airplane Flight Manual (AFM) be revised to prohibit autoland operation below 100 feet above ground level (AGL). Additionally, this action requires an inspection of the fuel system control panel (FSCP) to detect any mis-wiring, and modification or replacement of the FSCP. This AD also provides for an optional terminating modification for the requirements of the AD. This amendment is prompted by a report of improper wiring of the FSCP during production of these airplanes. The actions specified in this AD are intended to prevent degradation of the automatic landing system during flight due to improper wiring of the FSCP.
