Narrative:

In regards to the event on aircraft X; it arrived as a routine overnight check. I svced the oils; got the logbook and walked away. About 30 mins later; while I was doing a walkaround on another aircraft; maintenance control called out over the radio that aircraft X was going to go back out. I went back to aircraft X; started my walkaround. As I was doing my walkaround; the flight crew turned on hydraulics. It was then that I noticed fluid dripping from the nosewheel well. I notified the first officer; and asked him to write it up. They turned off hydraulics and I went to get tools and gloves and solvent. I cleaned the area with 'turbinaid' and wiped the area down. Wiped off the nose strut and tires. I had the flight crew turn on hydraulics; visually idented where the leak was coming from. Had the flight crew turn off hydraulics. Loosened the lines of the fittings that were leaking; tightened the fittings that were leaking and then re-tightened the lines; cleaned off the area with turbinaid; and wiped the area down. Had the flight crew turn on hydraulics. I visually verified that there were no leaks coming from the area.
