Why do you think that an explosion would result in a pristine piece of the airplane?
Could you please post the source stating that the stabilizer was in pristine condition?
It is not unusual, in a crash, to have something pristine. There have even been some cases of serious crashes in which a few passengers were in, basically, pristine condition (alive).
