Unsafe condition
This AD was prompted by the report of a flightcrew not receiving an aural warning during a lack of cabin pressurization event. We are issuing this AD to prevent the loss of cabin altitude warning, which could delay flightcrew recognition of a lack of cabin pressurization, and could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.
Affected ADs
This AD replaces AD 2012-19-11, Amendment 39-17206 (77 FR 60296, October 3, 2012).
