Czech Airlines Technics offers customers landing gear overhaul of Boeing 737 Classic and Next Generation aircraft for over 20 years. At its strategically located premises at Václav Havel Airport Prague, the company has completed more than 370 overhauls of landing gear sets. In line with its development plans, CSAT has invested in modernisation of the landing gear division and created a specialised workplace for surface hardening (the so-called balling) through purchases of a new machining centre, a painting box and an electroplating shop. The company leases or lands spare landing gear sets to its clients to be used during the time of their landing gear set overhaul performance. Currently, the company owns six spare landing gear sets (5x B737-800, 1x B737-700). The division records an annual average capacity of 32 landing gear overhaul with a short turnaround time. The division also offers related electroplating work in its own modernised electroplating shop and provides high-level professional technical support.
