The Electronics Module Assembly (EMA) of AmSafe’s airbag system contains the activation crash sensors. The Original Equipment Manufacturer (OEM) standard states the EMA refurbishment should be done at 7-years. And, you should replaced the unit after 14-years.
Here’s a cost summary of the EMA 7-year maintenance at an Authorized Cirrus Service Center:

The EMA 7-year maintenance is an example of a aviation indirect fixed cost. It’s a cost incurred regardless of the hours flown. Some pilots may not even know the cost exists until their A&P tells them. In a share aircraft ownership the expense should be split evenly among the members.
The AmSafe airbag system is a valuable safety addition. Cirrus began installing front seat airbags as standard equipment beginning with 2005 SR22 G2 serial number 1520 and 2005 SR20 G2 1541.
