A300/A310 003-25-33 HIGHLIGHTS To: Holders of A300/A310 Evacuation Slide/Raft System Service Bulletin A300/A310 003-25-33 Title: Equipment/Furnishings-Emergency Equipment A300/A310 Evacuation Slide/Raft System Fusible Plug Recall Effectivity: Evacuation Slide/Raft System P/Ns D30546-300, -400, and -500 series Evacuation Slide/Raft Syste, P/Ns D30545-100, -200 series Reservoir and Valve Assembly D17925-101,-103 and -113 Inflation Valve 61202-103, serial numbers listed herein. To re-call Fusible Plugs LOT P-21 and P-22 installed in inflation valves and inflation systems in service. Fusible Plugs are safety devices which safely vent the pressure from charged inflation systems in the event the inflation systems are subjected to excessive temperatures. Two incidents have been reported from the field where fusible plugs manufactured from the suspect lots have activated below their rated temperature of 174 degrees Fahrenheit. Testing conducted on fusible plug from suspect lots indicate that the plugs activate (vent gas) between the temperature range of 130 to 150 degrees Fahrenheit. Activation of the fusible plugs will vent all gas from the inflation system reservoir rendering the slide/raft unusable.

NOTE: Fusible Plugs, P/N B13984-3, Lot PA-21 or PA-22, shipped from Air Cruisers Company approximate dates of Oct 1, 2008 through Oct 1, 2009. Fusible plugs shipped as spares could be potentially installed on systems D30545-100, -200; D30546-300, -400 and -500 series. Also potentially installed on Reservoir and Valve assemblies D17925-101, -103, -113 and on inflation valves 61202-103. B. Reason To recall Fusible Plugs LOT P-21 and P-22 installed in inflation valves and inflation systems in service. Fusible Plugs are safety devices which safely vent the pressure from charged inflation systems in the event the inflation systems are subjected to excessive temperatures. Two incidents have been reported from the field where fusible plugs manufactured from the suspect lots have activated below their rated temperature of 174 degrees Fahrenheit. Testing conducted on fusible plug from suspect lots indicate that the plugs activate (vent gas) between the temperature range of 130 to ### Page 4 S.B. A300/A310 003-25-33 Page 2 of 7 ISSUE DATE: 27 Aug 2010 SERVICE BULLETIN 150 degrees Fahrenheit. Activation of the fusible plugs will vent all gas from the inflation system reservoir rendering the slide/raft unusable. C. Compliance It is recommended that this modification be accomplished at the next access to the equipment. D. Description NOTE: Only those organizations authorized by the FAA or other airworthiness authorities are permitted to perform this modification. Operators are to check all fusible plugs, B13984-3. Any fusible plug stamped with lot number PA-21 or PA-22 are to be scrapped. Check evacuation system, reservoir and valve assemblies and valves in spares for fusible plugs with the above stated lot numbers. Plugs with suspect lot numbers shall be replaced with new plugs following instructions detailed in the Component Maintenance Manual (CMM) 25-65-02. Re-identify with marking called out in accomplishment instructions. E. Approval FAA Cerification Info. D30546-( ) PMA The cofnizant airworthiness authorities have been advised of the interchangeability instructions outlined in this service bulletin. The inspection procedures described in this VSB have been reviewed and technically accepted by Airbus Design Office to apply to the Airbus fleet affected. F .
