The danger is of conflating the two main issues - the reason for the grounding, and the act of disposal. The obvious common offence is the making of false record (fraud by misrepresentation).
The Police, CPS and HSE have all refused to take action - the HSE saying it has no authority in cases involving airworthiness. A quite specific exemption apparently, even if deaths have occurred; although after the Cunningham case (closely related to this through a shared Type Airworthiness Authority) one takes what they say with a pinch of salt.
But if someone has evidence of other offences relating to the disposal, then best of luck. And whoever persuaded Private Eye to run their piece, well done.
