We are experienced in the production of the main L-159 trainer aircraft gearbox for a Honeywell F-124 engine, to which it is connected with an elastic PTO shaft. The gearbox drives the electric generator, two hydraulic pumps and air-starter turbines. The gearbox has an integrated oil system with an oil tank, pump and filter.

We also have long-term experience in the production of reducers for our turboprop engine PBS TP100 and ourturboshaft engine PBS TS100.
