Safety notes
- Dual GTN installations with mixed main software versions are incompatible and not approved for service or flight.
- Remove the aft mount from service for any crack, corrosion or bolt hole elongation. After a hard landing, inspect it for ground contact or damage.
- The library record lists the BELL 429 as piston, but registry data says turboshaft. Verify the engine type from the aircraft's own documents.
