Applicability: Model SF340A aeroplanes, serial number (S/N) 004 through 159 and Model 340B aeroplanes, S/N 160 through 459.

Requirement: Replace cargo compartment smoke detectors manufactured by Fenwall with smoke detectors, part number CGAB1201-01, manufactured by Cerberus SA in accordance with SAAB Aircraft AB Mandatory Service Bulletin SAAB 340-26-023 dated

Compliance: Before 28 December 2001.

This Airworthiness Directive becomes effective on 23 March 2000.

Background: The Luftfartsverket, the Swedish Civil Aviation Administration, has advised that field experience has demonstrated that smoke detectors, located in the cargo compartment, manufactured by Fenwall exhibit poor reliability, resulting in false warning occurring during high humidity environmental conditions.

This Directive mandates the replacement of the current cargo compartment smoke detectors with new units that have increased reliability and decreased maintenance.
