## Summary

We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVI airplanes. This proposed AD was prompted by a report indicating that there are design deficiencies in the software used for monitoring the disconnect for the flight control computer (FCC)-hosted flight controls actuation main ram linear variable differential transducer (LVDT). This proposed AD would require an update of the FCC software. We are proposing this AD to prevent the unsafe condition on these products.
