Products manufactured by and purchased from FLARM Technology Ltd are covered by a 6-month limited warranty (see GTC). This includes the 6 months legal guarantee in the EU ("reversal of burden of proof"), and assumes that there is no indication of incorrect installation or misuse.
For products sold in the EU, we may also consider legal guarantee repairs where the device is not older than 2 years, and the customer can demonstrate that the device was purchased new, and was correctly installed by a Part-M or Part-145 organization, or (under the supervision of) Part-66 certifying staff. To be able to consider a legal guarantee repair, a copy of the CRS and installation design documents (e.g. MCA) is required, as well as pictures of the installation covering the device, all antennas, and cabling.
