Proper Recycling
Just caught up with this thread.
Whoever was 'recycling' this aircraft was not doing 'proper recycling'
Whilst parting out is carried out per the requirements of EASA 145, assuming the aircraft still holds a CoM and CofA, If not,you do it under Part M rules.
In terms of the airframe destruction, there is currently no approved method. However, if you want to salvage the valuable materials, you don't just smash it up as it appears here. Any 'proper recycler' would have a method statement for the the aircraft type and follow the developed procedure.
After all, the 95 tonnes of Ali you would harvest would get you about $85,000 if you do the job properly. Not to mention what you would get for the stainless steel and titanium.
Just smashing it up - whoever was doing that didn't know what they were doing.
