Comprehensive Upgrade Aims To Nearly Double Engine Durability

Pratt & Whitney has introduced a comprehensive 35-part retrofit kit, known as the Hot Section Plus (HS+), designed to nearly double the time-on-wing for Airbus A320neo operators. The kit targets the most thermally stressed areas of the engine, aiming to close the durability gap between existing fleets and the new GTF Advantage standard. With certification expected by late 2026 and widespread availability in Q1 2027, the upgrade is positioned as a critical bridge for the thousands of A320neo aircraft already in service, as reported by Simple Flying.
