Applicability (c) This AD applies to all Dornier Model 328-100 airplanes, certificated in any category. Unsafe Condition (d) This AD results from fuel system reviews conducted by the manufacturer.

In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
