Let's calculate dynamic pressure for max design speed and 500 kts indicated at sea level in standard conditions.
At 350 KIAS it is 3.11 psi
At 500 KIAS it is 6.34 psi
; which is more than a double
I would say this is above elastic modulus ((design x 1,5) x 1,15 if I remember correctly) for a structure of this type and permanent damage would occur.
