This Directive requires owners/operators of all Partenavia P68 aircraft to have the fuel selector valve control system inspected following VulcanAir Service Bulletin SB 113. It sets an initial inspection deadline (50 flight hours or three months) and recurring checks (every 100 flight hours) and requires inspections when certain symptoms appear. The stated purpose is to correct an unsafe condition in the fuel selector system; compliance imposes recurring inspection costs and operational scheduling impacts on aircraft operators.
