This issue has come up in our squadron once again. This time the FE serviced it in flight, told hydro that it may be over serviced after they landed. When day shift came in, they had a mess to clean up. It\'s gotten to the point we got MX Officers meeting with Operations Officers. I actually heard the MX Officer say that the pressure in the reservoir could have caused it to rupture damaging the airplane or personnel. Now, I have been flying for a long time and I have never heard this one. Any comments??:laugh:
