Police arrested 31-year-old Josh Hoch, whose Linkedin profile lists him as the owner, director and chief pilot of Hoch Air, on Tuesday after a three-month investigation.

His charges stretched back to July 2014, when he allegedly attacked an aircraft engineer in Charters Towers, leaving him with "permanent and life-changing head injuries", and raised serious questions about aircraft security at Mount Isa and Charters Towers airports.

Police alleged Mr Hoch targeted two private air charter operations, but not major commercial carriers, at Mount Isa and Charters Towers.

Aviation experts found "abrasive material" applied directly into engines caused the "catastrophic engine failure" and the forced landing of two planes, police alleged.

Another two suffered engine failures identified before they took off.

The incidents sparked a safety review at Mount Isa Airport, which police said resulted in new measures put in place and no further aircraft being damaged.

Police also alleged fraudulent insurance claims, flying without a licence, dangerous operation of aircraft and "numerous" safety breaches, mostly at Mount Isa and Charters Towers.

Police said a "significant witness had come forward in relation to the aircraft damage but appealed for anyone else who knew anything to get in touch.

Mr Hoch's 342 charges include numerous counts of endangering the safety of a person in a vehicle with intent, dangerous operation of a vehicle, flying aircraft without a licence, fraud offences, and offences in relation to aircraft.

He is due in Mount Isa Magistrates Court on Wednesday.
