Lufthansa Technik Turbine Shannon (LTTS)

Lufthansa Technik Turbine Shannon, also known as LTTS, repairs engine parts in Shannon, County Clare, Ireland. It is based in the World Aviation Park. The company calls itself an Engine Parts and Accessories Repair shop, or EPAR, and it works on high pressure and low pressure turbine parts.

The core work is the repair of nozzles, shrouds and shroud hangers, where the company has more than 20 years of experience. Most of these parts come from CFM56 engines, which fly on the Airbus A320 and the Boeing 737. LTTS has also grown its work on CFM56 and V2500 engine manifolds. A second, recently opened site in Shannon supports this work.

The company was established in 1992. It has more than 400 employees and more than 16,400 square metres of floor space. Its customers include OEMs, engine overhaul shops and parts traders in Asia, Europe and the Americas. It describes itself as a lean and flexible organisation that keeps investing in equipment, training and product development.

The product list is clear. Low pressure turbine nozzles are repaired for CFM56-5A, 5B and 7B engines. High pressure turbine shrouds are repaired for the same engine versions, using OEM approved thermally densified coatings. The shop has OEM approved capability to repair high pressure turbine shroud hangers for CFM56-5B, 5C and 7B engines, using CNC milling and TIG and SWET welding.

LTTS also repairs low pressure turbine cooling manifolds for CFM56-5B and 7B engines, and external tubes for CFM56-5B, 5C and 7B engines. It repairs the low pressure turbine outer stationary air seal segment for CFM56-5B, 7B and 7BE engines, and it has an external OEM approval for one repair on the stage 1 seal segment. A materials replacement service gives engine builders scrap replacement, slots and set management.

The company designs and develops new repairs together with engine makers such as GE, CFMI and Rolls-Royce. This covers current and future products, for example the CFM LEAP and the Rolls-Royce XWB. LTTS also sells and exchanges parts from its range. Two related services sit near Dublin. TSP Dublin is a technical service provider for engine lessors, helping with engine handovers between operators and lessors. MES Dublin is a mobile engine service that offers on-site and on-wing repairs for CFM56 and LEAP-1A engines.

LTTS is certified to the EN 9110 quality standard. It also meets ISO 14001 for the environment and ISO 45001 for health and safety.
