The National Fire Protection Association’s technical committee on airport facilities has dropped a proposed requirement for automatic sprinkler systems in Group III hangars. The revision to the NFPA 409 Standard on Aircraft Hangars is set to be submitted to the NFPA Standards Council for final approval, according to NATA, and included in the 2010 revision of NFPA 409. If the revision remains unchanged, it will require automatic sprinkler systems in newly built Group III hangars (less than 12,000 sq ft) only if local building codes require the sprinkler systems or if the hangar is to be used as a residence.
