Aviation Helmet Standards

The DOI/USFS Aviation Helmets Standard Specification will provide an avenue to allow non-military helmets to be considered for acquisition within agencies. Manufacturers and distributors can test their helmets using an ISO certified laboratory to the DOI/USFS Aviation Helmet Standard. Those meeting or exceeding these standards can be issued a certificate of compliance by the laboratory. These helmets will be identified by the manufacturer and model type on the OAS website on this page within 30 days of receiving the certificate.

Active Noise Reduction (ANR) Technology

Active Noise Reduction (ANR) technology possess the ability to improve communication, reduce fatigue, and may also reduce hearing loss over time. Currently, most ANR earcups are manufactured with a hard/rigid material that adversely affects impact performance. The probability of needing that protection is often "low" (for most mission types) with the severity of such an event resulting in "high" (i.e. death or serious injury). In comparison, the probability of experiencing negative aspects involving the aforementioned areas without ANR are more probable, but less in severity (again, for most mission types).

Flight helmets that meet the DOI USFS standard without ANR installed may be equipped with ANR technology provided by the Original Equipment Manufacturer (OEM) or designated representative(s) however, managers and helmet users should be aware of the degraded impact performance resulting from earcups constructed of inflexible (hard) materials associated with most ANR systems. Please contact your respective Aviation Managers for specific agency/bureau/region/unit requirements prior to procuring any type of helmet.

Please review the DOI/USFS Aviation Helmet Standard 4.3 (Updated 11/13/2019) and Interagency Aviation Life Support Equipment Handbook/Guide (Updated 03/15/2021) for specific information.
