Regulation No. 88 requirements. This proposed AD wOrd also require the

accomplishment of certain fuel system modifications, tie initial inspections of certain

repetitive fuel system limitations to phase in those inspections, and repair if necessary.

This proposed AD results from a design review of the fJel tank systems. We are

I 'NmAl.S/s[G

proposing this AD to prevent the potential for ignition SGlurcesinside fuel tanks caused y

latent failures, alterations, repairs, or maintenance aetiols, which, in combination with

flammable fuel vapors, could result in a fuel tank exPloJon and consequent loss of the

airplane.
