Maintenance and Modifications
U.S. GIV Owners Have 36 Months To Retrofit Gust Locks
Action stems from NTSB safety recommendation outlined in its final report of the GIV that crashed on takeoff from Massachusett’s Bedford-Hanscom Field.

U.S. owners and operators of Gulfstream GIVs, GIV-SPs, G300s and G400s have 36 months from today to comply with FAA AD 2017-13-11, which requires modification of the gust lock system and a revision of the maintenance or inspection program to incorporate functional tests. This action stems from NTSB safety recommendation A-15-31 outlined in its final report of the GIV that crashed on takeoff from Massachusett’s Bedford-Hanscom Field in May 2014. All four passengers and three crewmembers were killed.
