Narrative:
While servicing the main landing body gear strut on the left side with a hydromite machine, I was distred several times by changes in personnel helping me service the strut. These distrs occurred while I was purging the strut of excess nitrogen bubbles. Purging requires you to fill, then drain the strut of excess fluid. I believe these distrs may have caused me to not drain the excess fluid from the strut.

Title: SVCING MAIN GEAR STRUT, DISTRS INTERRUPTED PURGING EXCESS NITROGEN BUBBLES. EXCESS FLUID NOT DRAINED FROM STRUT.
Narrative: WHILE SVCING THE MAIN LNDG BODY GEAR STRUT ON THE L SIDE WITH A HYDROMITE MACHINE, I WAS DISTRED SEVERAL TIMES BY CHANGES IN PERSONNEL HELPING ME SVC THE STRUT. THESE DISTRS OCCURRED WHILE I WAS PURGING THE STRUT OF EXCESS NITROGEN BUBBLES. PURGING REQUIRES YOU TO FILL, THEN DRAIN THE STRUT OF EXCESS FLUID. I BELIEVE THESE DISTRS MAY HAVE CAUSED ME TO NOT DRAIN THE EXCESS FLUID FROM THE STRUT.
