There was a whole chunk in the Naval Aircraft Maintenance Manual (NAMMS) on what to do with a rogue aircraft, how to get one certified as such and how to get rid of it.
Then there was XV227- one of the pre-production Lynx HAS Mk1's- It was near impossible to get it avionic systems serviceable simultaneously and any correspondence between the topic 10 wiring diagrams and the actual aircraft was apparently a coincidence. I think it was eventually 'sold' to Pakistan. XV699 was the complete opposite- always serviceable.
