Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of specific SAAB SF340A and 340B aeroplanes (listed serial numbers) that have a forward-lavatory fire extinguisher, part number 55-373 with external service, to carry out the inspections/modifications set out in SAAB Service Bulletin 340-25-235. The measure is intended to prevent capillary-tube damage that has led to unintended extinguisher discharge and loss of required waste-bin fire protection, and it imposed a compliance deadline (before 27 June 1997).

Amdt 1

Lavatory Waste Bin Extinguisher 13/98

Applicability: Model SF340A with serial numbers SF340A-121, and -125 through -159 and Model 340B with serial numbers 340B-160 through -360; with a fire extinguisher installed in the forward lavatory, part number 55-373 (with external service).

Requirement: Action in accordance with SAAB Aircraft Service Bulletin 340-25-235.

Note: LFV AD 1-106R1 refers.

Compliance: Unless already accomplished, before 27 June 1997.

The compliance of the initial issue of this Directive remains unchanged. This Amendment becomes effective on 3 December 1998.

Background: The capillary tube of the waste bin fire extinguisher in the forward lavatory has been found to be fractured / bent during maintenance inspections. This damage has caused the discharge of the extinguisher, and consequently no fire protection of waste bin contents as required by AD/GENERAL/48. This Directive requires certain actions to prevent capillary tube damage.

Amendment 1 is issued in response to a revision of the related LFV AD issued to limit applicability.

The original issue of this Airworthiness Directive became effective on 27 March 1997.
