Inspect individual replaced or re-installed passenger compartment fluorescent lamps for correct installation in accordance with SB 340-33-047 Revision 01 or later approved revision. Repetitive inspections of individual lamps is optionally terminated by incorporation of Modification 2936 (SB 340-33-048 refers). Note 2: LFV SAD 1-113R1 refers. Compliance: For Requirement 1 - Within six calendar months after the effective date of this Directive. For Requirement 2 - Within one week from the date of lamp replacement or re-installation. This Airworthiness Directive becomes effective on 11 January 2010. Background: This Directive results from a routine review of airworthiness directives for SAAB 340 model aeroplanes. The review discovered that all references to the inspection, rework and replacement of the ceiling and lavatory fluorescent lamp holders had been removed from AD/SF340/54 Amdts 1 and 2. In order to avoid confusion AD/SF340/54 Amdt 2 has been cancelled and two new directives have been published reflecting the requirements of LFV SAD 1-103R1 and 1-113R1 respectively.
