Wings Air flight IW1327, an ATR 72-600, was descending to 8,000 feet when all the Display Units (DU) went OFF and the autopilot disengaged. The pilots looked at the overhead panel and found the DC Gen 1 was faulty. After a few seconds, everything was back to normal but then the DUs went OFF again but now the DU 2 and 4 were alive.
The symptoms were repeated several times (about 5 times) and the IESI sometime was OFF. The pilot did not take any action because they were focusing on the flight and preparing for landing on runway 21 of Makassar where there was a terrain before runway 21. After landing in Makassar, the pilots found the pressurization fault which made the pax door could not be opened. After solving the pressurization system and the passenger disembarked, the FO smelled smoke from the avionics rack and the 2nd FA informed the crew there was smoke on row 3 to 6.
