I think this is what happened
US provided 20 cobras for flying condition which were added
It also provided 20 cobras for spares but to make sure pak did not make them fly worthy all cabling /wiring was cut out but had everything else to be converted to spares
Pak inventory looks like is more than usual ie 20 older cobras plus 20 new one delivered in 2010ish so should be around 40’max minus attrition
Pak/pac took the challenge and used wiring at pac w/o tech docs to recover and replace lost ones there were at least 2/3 accidents and losses over the years since 80s
I think they used 10-12 to be converted to spare and rewire 8-10 more to bring them to flight status
There were pic of cobra being unloaded from c-141 with all wire cut out at one time
Again this is my theory but I can be totally wrong
