Dear Mr. Wanczyk:

This responds to your letter concerning exceptions accorded to air bag modules that are installed in completed components under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you inquire whether a completed aircraft seat assembly containing an approved air bag module is excepted from the requirements of the HMR under § 173.166(d).

The answer is yes.  An approved air bag module or seat-belt pretensioner that is installed in an aircraft or completed aircraft component (e.g., seat assembly) meets the intent of § 173.166(d) and, therefore, is not subject to the HMR.

I trust this satisfies your inquiry.  Please contact us if we can be of further assistance.
