AD: McDonnell Douglas (Boeing)

AD NUMBER: 2008-02-08
MANUFACTURER: McDonnell Douglas
SUBJECT: Airworthiness Directive 2008-02-08
SUMMARY:
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes.

This AD requires electrical bonding of the fill valves for the right and left main fuel tanks, the fill valve and pipe assembly for the center wing fuel tank, and the defuel shut off valve.

This AD results from a fuel system review conducted by the manufacturer.

We are issuing this AD to prevent improper bonding of the fill valves and defuel shutoff valve for the main fuel tanks and center wing tank, which, in combination with a lightning strike, could result in a fuel tank explosion and consequent loss of the airplane.
