Plain English Summary

1/10 complexity

This is a mandatory safety inspection order for owners and operators of Gulfstream G1159 and G-IV series aircraft (business jets).

What it requires: You must inspect the pitot-static system connections on your aircraft. The pitot-static system is the network of tubes and sensors that feed critical flight instruments like your airspeed indicator and altimeter. If these connections are loose or leaking, pilots get false readings—which can be deadly.

How to comply:

When: Within 200 hours of flight time after 31 December 1977
How: Follow the instructions in Gulfstream Customer Bulletin 251

Why it matters: Faulty pitot-static connections can cause catastrophic instrument failures. This directive ensures these critical connections are checked to prevent accidents caused by incorrect altitude or airspeed readings.
