             Requirement: 1. Examine the fuel strainer assy for evidence of leaks. Inspect both the fuel strainer assembly and exhaust tailpipe for evidence of chafing with the lower engine cowling. If any evidence of chafing is found carry out Requirement 2 prior to further flight.

             2. Modify lower engine cowl in accordance with Cessna SB97-28-01 dated June 06, 1997.

            Note: FAA Priority Letter AD 97-12-06 dated June 8, 1997 refers.

             Compliance: 1. Unless previously accomplished, comply with Requirement 1 prior to further flight and, thereafter, at each pre-flight inspection until Requirement 2 has been carried out.

            2. Within 10 hours time in service from the effective date of this directive. This airworthiness directive becomes effective on 16 July 1997.
            Background: The manufacturer has reported that the fuel strainer drain may chafe against the lower engine cowling. This can cause the extension nut to the standpipe connection to fail resulting in fuel spillage. Standpipe failure could also result in a fire hazard or engine stoppage due to fuel loss.
