## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB 2000 series airplanes. This proposal would require performing a one-time inspection of the dropout boxes of the passenger oxygen system to detect discrepancies and determine whether the system operates properly; correcting any discrepancy found; and reworking or installing new components, if necessary. This proposal is prompted by a report indicating that the oxygen system failed to operate correctly after activation at a low cabin pressure due to the incorrect installation of the oxygen masks or oxygen generators during manufacturing. The actions specified by the proposed AD are intended to ensure that a sufficient supply of oxygen is provided to airplane passengers in the event of rapid decompression of the airplane.
