Plain English Summary

1/10 complexity

This directive orders owners of specific Cessna 500 Citation business jets to modify the aircraft's static port — a small external opening that feeds air pressure to critical flight instruments like altimeters, airspeed indicators, and vertical speed indicators.

Who must comply? Owners and operators of Cessna 500 aircraft with serial numbers 0001–0142, 0144, 0146–0149, and 0151–0349.

What action is required? The static port must be modified exactly as described in Cessna Service Bulletin 34-20, Revision 1 (a manufacturer-issued technical instruction). This ensures the instruments receive accurate atmospheric pressure readings and display correct altitude and speed to the pilots.

By when? Unless the work was already completed earlier, the modification must be performed within 100 hours of flight time after 28 February 1979.
