The Pitts special S2B PH-PEP from sky unlimited is a high performance aerobatics aircraft and has a glass cockpit (polycarbonate) within a metal frame.

The plane has a 9-litre six-cylinder 260HP engine and a top speed of 315 km/hour.


Scroll through 11 pictures from welding a cockpit frame.
The cockpit opened during a flight and crashed down to the ground. It involved thin wallled 4130 chrome molybdeen tubes, the maintenance company knows our experience and ask us for the Repair.

We straightened the frame, calculated the heat plan and welded the cracks.
