H3 Sport

Maintenance & operating costs

The maintenance program for the H3 Sport is one of this machine’s greatest advantages. The entire helicopter has been designed for ease of access, simplicity and low cost of maintenance for the owner. It can be performed easily thanks to detailed but very simple technical procedures.

The general TBO of the H3 Sport is at 2000 h and has no calendar limited service life. Service inspections are spaced at every 50, 100, 250, 500, 1000 and 2000 h.
