## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 747-8 and 747-8F series airplanes. This proposed AD was prompted by a report that flightcrew oxygen masks did not deploy correctly during flight testing. This proposed AD would require an inspection to determine if certain oxygen masks/regulators and stowage boxes are installed and replacement if necessary. We are proposing this AD to address the unsafe condition on these products.
