## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held P3HAFEX fire extinguishers (fire extinguishers). This proposed AD was prompted by reports of a quality control issue on certain fire extinguishers, where the spindle geometries of the fire extinguishers were found to be out of tolerance. This proposed AD would require removing affected fire extinguishers from service. The FAA is proposing this AD to address the unsafe condition on these products.
