How does AMA know the weight? Especially if they have to pay a claim from an accedent which may only be a pile of smoldering jet? This whole weight thingy seems very subjective to me. Moreover, who is running around with a scale checking jet weights?
In practice, the issue would not come up unless there were a claim. If it were a very large liability claim, the insurance investigators would work to recreate the weight of the airplane. If the conclusion was there was no way it was under 55 pounds, they deny the claim and its up to you to prove otherwise.
