According to Square Trade, their procedure for the repair of a damaged drone is:
1. They will send you a prepaid shipping label to the nearest DJI authorized repair facility.
2. After you receive a detailed invoice from DJI of what is involved in the repair, you send it to Square Trade.
3. Square Trade will then examine the repair invoice and determine whether or not it is covered.
Square Trade also emailed me a copy of the detailed contract. I read it through and about the only thing that I could find where they would not have to do the repair is if it is the result of negligence, although there are a number of other exclusions like intentional damage, acts of nature, theft, or loss.
I suppose it would all depend on how broadly Square Trade wants to interpret "negligence." I do have a copy of the online transcript I had with one of their customer service reps who did clearly state that damage while flying while flying would be covered.
I think I will email them directly with a specific example of damage, like in the course of landing it crashed into trees, and see what their reply is.
