Compliance required as indicated.

Reinspection of the pressurization system indicates that under certain conditions a single malfunction in the pressurization static system could cause the aircraft to be pressurized beyond the structural limits.

(a) Rework existing static system to provide either

(1) A separate static sensing source for each cabin outflow valve, or

(2) A static sensing source common to the two outflow valves and a separate static sensing source for the cabin pressure controller.
