b.         If previously accomplished in accordance with AD/CESSNA 400/111 Requirement 1 or AD/CESSNA 400/112 Requirement 1 - Within the next 200 hours TIS after compliance with AD/CESSNA 400/111 Requirement 1 or AD/CESSNA 400/112 Requirement 1 and thereafter at intervals not exceeding 200 hours TIS until Requirement 3 is accomplished.

            Background The United States Federal Aviation Administration (FAA) has received evidence of chafing and/or arcing of the electrical wiring leading to the fuel boost pump reservoir. Further investigation confirmed reports of chafing and/or arcing of the fuel boost pump wiring inside the fuel pump reservoir that supplies fuel to each engine.

            AD/CESSNA 400/111 required a one-time inspection of the fuel boost pump wiring inside and outside the boost pump reservoir, and the repair or replacement of the wiring as necessary. The original issue of this Directive, which superseded AD/CESSNA 400/111, required repetitive inspections until the new design wiring harness are installed and the boost pumps either modified or replaced. These actions were intended to detect and correct chafing and/or arcing of boost pump wiring, which could result in ignition of explosive vapour within the fuel storage system.

            This amendment clarifies what an improved design fuel pump is and requires pumps to be inspected before installation.

            This original issue of this Airworthiness Directive became effective on 10 July 2003.
