## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held fire extinguishers (fire extinguishers).This AD was prompted by a report of a safety issue on certain fire extinguishers, where certain environmental factors may prohibit the discharge of the fire extinguisher. This AD requires repetitively inspecting the fire extinguisher, and depending on the results, removing the fire extinguisher from service. This AD also prohibits installing an affected fire extinguisher unless it passes the required inspections. The FAA is issuing this AD to address the unsafe condition on these products.
