Engine Alliance extends time on wing with GP7200 HPT durability improvements

The Engine Alliance has released a series of GP7200 engine enhancements. Largely focused on high pressure turbine (HPT) durability, the improvements will benefit all GP7200 operators, especially those who operate under tough environmental conditions. “These changes will extend time on wing by up to 50% in hot and sandy environments,” said Dean Athans, President of the Engine Alliance, “and they will do so with no impact to fuel performance. These changes will further cement our lead as the most reliable and the most fuel efficient engine for the A380.” The latest HPT design was frozen in October 2013, with successful introduction of new hardware to production on schedule in June 2014. The majority of the improvements are aimed at the HPT stage 2 nozzle module and can be installed at quick-turn repair lines or at normal shop visit.
