Gulfstream IV (GIV) Safety Record | AeroGurus

Editorial safety summary — see Gulfstream GIV listings and consult a qualified A&P/inspector for individual aircraft decisions.

The Gulfstream IV (1985-2003, including the IV-SP variant) is the classic large-cabin intercontinental Gulfstream that defined the segment before the modern G450 successor. Rolls-Royce Tay 611-8 turbofans with excellent reliability, two-crew operation, and the Gulfstream operational culture that emphasises professional flight crews and rigorous recurrent training. Safety record is strong consistent with the Gulfstream fleet generally. As with all 1980s-90s large-cabin jets, mandate-upgrade investment (ADS-B Out, FANS, MNPS, RVSM) on older GIVs has been substantial; the modern GIV/GIV-SP fleet is generally compliant.
