Following an inflight dual inverter failure; one of which was successfully reset; the captain of a CE560 reported pressure from his company to alter aml write up by excluding the word 'dual' and allowing them to defer the inverter that failed to reset; thereby allowing the aircraft to be dispatched with the completely failed inverter deferred. The flight crew demurred.

Narrative:
We experienced an in-flight dual inverter/AC failure. We were able to reset inverter #1 but #2 would not reset. After landing I wrote it up as it happened 'dual inverter failure; #1 reset; #2 did not' and sent it in.I was then called by maintenance and asked to change it to a single inverter failure. I conferred with my co-pilot and we agreed not to do this. After talking to a chief pilot and maintenance again; a write-up was faxed to me where what I sent in had been changed to 'inverter failure; #1 reset; #2 did not;' identical except the word 'dual' was removed and it was MEL'd. I was asked by maintenance to write 'entered in error'; sign it with my certificate number; enter it in the logbook and fax a copy back to them. I then sent in another write-up; identical to the first; and the aircraft was grounded. The aircraft never moved and two inverters were flown in and installed.
