## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX, and 1125 Westwind Astra airplanes. This proposed AD would require a one-time inspection for discrepancies of the nose wheel steering assembly of the landing gear, installing a warning placard on each nose landing gear door, and corrective action if necessary. This proposed AD is prompted by reports of failure of the steering brackets of the nose wheel steering assembly, and in one incident, loss of steering control. We are proposing this AD to find and fix these discrepancies, which could result in loss of steering control and consequent reduced controllability of the airplane.
