Narrative:
On may/xa/06; I left for field service with one other mechanic to change the #2 engine driven fuel pump and mec (main engine control) on air carrier X. Prior to departure; the supervisor on duty upgraded me up to an inspector by completing same form. One time rii upgrade form; after this was accomplished; the supervisor was informed that an additional mechanic was required for this road trip since one would now be an inspector and the other one mechanic would be left to complete the task of changing the engine driven fuel pump and mec alone. The supervisor's reply was essentially that he was not going to send 3 people on a road trip due to this. I assisted the change of the mec and fuel pump with the other mechanic. This is not an uncommon practice to the extent that I didn't realize I was not supposed to sign off the inspection; even though I assisted as a mechanic and upgrade inspector.
