The data are through 2005. The 737NG hull losses rate still stands at zero. If you have other data, please provide it with a source.

Total number of 733/734/735 hull losses (manufactured over the last 18-19 years) through 2005 was 19, not 26. The 738 is not included since there have been zero of those. The total number of A318/319/320/321 hull losses through 2005 were 12. These hull losses provide respective accident rates of 0.38 and 0.57 quoted earlier. If you have other data, please provide it with a source.

The hull loss rate for the other airplanes and the 744 are:
A330: 0.00
A340: 0.92
777: 0.00
744: 0.75
Since the A340 rate is worse than the 733/734/735 and the 744 (a non-FBW airplane), while the A330 and 777 rate is the same as the 737NG, there is no satistical basis for saying that FBW is safer.
If you think that FBW is safer, that's fine, but the statistics do not back you up.
By the way, the 748 will not be FBW as its primary flight controls will be similar to the 744.
