Follow-up inspections have shown that there is a possible assembly problem affecting individual Mammut and Snowpulse avalanche airbags from the Winter 2011/2012 and Winter 2012/2013 production seasons. The problem is an improperly screwed in connector between the deployment mechanism and the venturi valve.
Since Mammut cannot rule out that this problem could result in a loss of function in the event of use, we hereby request that all customers inspect the connection in accordance with the following instructions.
The Service Bulletin affects Mammut and Snowpulse avalanche airbags with Inflation System 2.0 from the 2011/2012 and 2012/2013 production seasons. You will find instructions on how to determine the production season of your avalanche airbag below. The Service Bulletin for inspection does not affect avalanche airbags made before or after these seasons because of a different construction.
Mammut recommends all airbag owners to check the connection as part of their regular equipment check. All safety equipment should be frequently checked to ensure serviceability.
