What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas airplanes described previously. This AD requires installing bonding jumpers to the airplane wing structure from the fuel system in-line electrical solenoid valves along the left and right wing front spar. 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 lines that could create a potential ignition source, which, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Which aircraft AD E7-10669 applies to
Whether AD E7-10669 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
