You should follow the instructions at the top of the aircraft.cfg file.
The following is from a TDS 737 for FSX, but they will be similar for P3D.
So the top of your aircraft.cfg file should look something like this:
// WARNING NEVER TAKE OFF "FREEWARE_(C)_TDS_16AUG2013" from title= -------------------------
// If you do those , wings will be gone and other unexpected things will happen. |
// Title must be under 127 character since FSX will cause error when exceed. |
