Rolls-Royce claims to have effectively eliminated aircraft-on-ground (AOG) delays in its civil aerospace business after increasing engine maintenance and refurbishment work during the first half of 2026. According to Rolls-Royce, it increased large-engine maintenance output by 13% during the six months ending June 30, 2026. “We have also effectively eliminated aircraft on ground, providing a significant operational benefit to our customers,” Rolls-Royce CEO Tufan Erginbilgic said. Rolls-Royce also reported progress on upgrades intended to keep engines installed on aircraft longer between maintenance visits. Flying hours for business aviation and regional aircraft engines rose 9%.
