Narrative:
Road trip from ZZZ to ZZZ1 for aircraft X. Found aircraft maintenance not documented by multiple mechanics. Multiple task found to be started; but not documented on [system]. Informed mechanics to document their maintenance on [system]. Was updated by mechanics on was what was accomplished. No stories matched. Heavy wind throughout operation and possible hydraulic activation during cable tension adjustment. Documentation does not match maintenance performed. Cable tension was released without proper pins installed. Incorrect cables adjusted. Inspected aircraft and found multiple turnbuckles with broken turnbuckle clips. Cables now require replacement. Found multiple broken turnbuckle safety clips in cabin of aircraft.inspected aircraft and found multiple turnbuckles with broken turnbuckle clips. Incorrect control cable adjusted. Now two flight control system require confirmation of correct installation. Suspect possible third flight control system.maintenance not documented; maintenance manual not followed. Upon realization of incorrect maintenance and documentation performed; contacted lead; supervisor; base manager for further guidance. Documented mistakes found.
