Crash with Index out of bound

[ydemartino]

Hello,

I'm getting a crash when trying to parse the following pass. This is a pass from AirCorsica:

M1TESTTEST/TESTTES    EZPNSNK MRSAJAXK 9807 063Y003A0001 32C>2180      B   01464060360010E             0

I replaced the user name with same character length, everything else is left untouched.

Here is the associated stacktrace:
