Engine registration
Registration of engines serves as an important tool for the ROTAX® network, assisting in the following ways:

  • Creates a better view of active fleet (Location & Size)
  • Provides a base for general spare part requirement and suitable service location
  • Selection of commercial or private operation provides a general indication for the yearly usage of the associated aircraft

General planning
Proper pre-planning for scheduled maintenance and overhaul times ensures availability and avoids down time.
In general, ROTAX® suggests ordering parts in advance:
3 months for larger inspections (600 hours and/or gearbox)
6 months for overhaul / engine replacement
