I have fixed this (and tested with that particular fsdb file) with commit https://github.com/FAI-CIVL/FAI-Airscore/commit/79ed346b8f1285629781bb1296bb9f0439cc2306

@biuti from looking at the code around this it looks like the bug was a typo but maybe you want to check that this pattern is not elsewhere in the fsdb import code.

[biuti]

I'll check.
