From AN2 Driver:
I recall reading the NTSB report on that one and that the PIC and FE were severely criticized because in the rush to get down NOW they forgot one or two items, which the experts afterwards found could have contributed to the difficulties in extinguishing the fire. I thought to myself even then, and that was pre- SR111, that this was a fairly easy thing to say to them for someone who had not been there.
Though the not the full report,
here is a letter from the NTSB to the FAA describing the incident, summarizing the cause and "pointing the finger".
