A cracked spinner fairing that caused the failure of a Gulfstream IV Rolls-Royce Tay engine resulted in revised inspection procedures that could help detect such cracks before they cause damage. The event took place on June 17, 2023, and the final NTSB report cited as a contributing cause “inadequate spinner fairing inspection procedures that did not require removal of the spinner fairing to inspect the aft side for earlier detection of crack indications.”
