## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, 737-200, 737-200C, 737-300, 737-400, 737-500, 737-600, 737-700, 737-700C, 737-800, 737-900, 737- 900ER, 757-200, 757-200PF, 757-200CB, 757-300, 767-200, 767-300, 767- 300F, and 767-400ER series airplanes. This proposed AD was prompted by reports indicating premature aging of certain passenger chemical oxygen generators. This proposed AD would require repetitively replacing affected chemical oxygen generators with serviceable parts. This proposed AD would also limit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
