Narrative
Yesterday Date; last day of a four-day trip; during the third and final flight of the day; Aircraft X departed at XA19 local time from ZZZ1 to ZZZ; after landing in ZZZ we experienced smoke in the cabin and cockpit; which made this flight end in an evacuation on the taxiway.The flight started normal; we got vectored for a few minutes by ATC as we got close to ZZZ area; but that did not cause any mayor delays.I was the Pilot Flying and Captain Name was Pilot Monitoring. After a normal visual approach and landing in Runway XXL at ZZZ airport; we transferred controls and exited the runway. We started smelling a rubbery burning smell; and both acknowledge it deciding to stop on Taxiway 1 between [Taxiways] 2 and 3 facing south. After we came to a full stop; we started seeing the smoke in the cockpit and at this moment the Flight Attendants called the flight deck on the intercom. The Captain told me to answer the intercom and at the same time he notified ATC. Flight Attendant 1 stated that there was a lot of smoke in the cabin; and it was filling up very quick. I immediately communicated this to the Captain and decided to evacuate; he called for the Evacuation Checklist. We ran the checklist and evacuated the aircraft in a very organized manner. No one was injured during this process and after a few minutes the emergency vehicles showed up.The fire department went inside the airplane with their equipment to detect the source of the smoke and they could not find anything that was a fire hazard. After this they cleared the Captain and myself to go inside the plane as needed. One of the firefighters and I completed separate passenger counts to verify that everyone was accounted for; and then one of the paramedics asked me to find out if anyone needed medical attention. We had 3 passengers that needed a wheelchair so I focused my attention on those 3 passengers. They were offered a seat in the ambulance while the buses arrived. When I asked if anyone needed medical attention; one lady told me that she was diabetic and her medicine was inside the plane; I directed her to the ambulance where the paramedics took care of her. Besides that; everyone seemed calm and the situation was under control. The fire department had a cooler with some water bottles but it was not enough for everyone so I went inside the plane; after it was safe and cleared by the fire department; and grabbed a few bottles of water and cups for passengers to drink. I handed the water and cups to the flight attendants; and they did an improvised water service. I can say that the crew managed the situation well and everyone was evacuated to safety.Once the buses picked up the passengers and the flight attendants; the captain and I decided to stay with the plane in case further action was needed from us. Once maintenance came; they started the APU and PACKS to recreate the situation; immediately we received different messages on the EICAS related to PACK Failure; including L PACK AUTOFAIL Caution MSG and metal shavings were coming out the air vent in the flight deck. This Caution message never came up before when we experienced the smoke in the cabin.After this the plane was tugged to a maintenance pad; and after coordination with airport operations and maintenance; it was taxied to Gate X where passengers were able to get their belongings. Myself and my crew had the same plane; Aircraft X; since we started in the morning. During the initial walk around inspection; I noticed that the nose gear strut was very high; more than usual. I communicated this to the Captain but we found out on the maintenance log that it was serviced a couple days ago; so it made sense for the strut to be higher than normal. As passengers came in and weight was added; the strut started compressing and it was normal. As weight was taken off; the strut came back up; and this caused the passenger door to open more than normal and the stairs to be very steep; what made it harder for some people to go down the stairs. This caused a delayed for some passengers; especially older people. This is something that did not cross my mind until that moment but it should be taken into account for future maintenance on the nose gear strut.
Second reporter narrative
After our nose wheel on aircraft Aircraft X touched the ground after landing Runway XXL (ZZZ) at around XB40; we started smelling a burning rubber smell. Immediately thereafter we started noticing smoke building in the cockpit and the cabin crew called us at that same moment to report smoke in the cabin as well. We exited the runway and parked the aircraft south of high-speed Taxiway 3 on Taxiway 1 and told Ground Control our position. We promptly completed the Emergency Evacuation EPC items; to include the 'Evacuate; Evacuate' command. The smoke in the cockpit did not seem to get any thicker as we were completing this process; however; it was pungent. After we had shut down everything; the smoke did not get any worse. All passengers and 4 crew members were off the aircraft shortly thereafter. The ZZZ fire rescue teams arrived just a few minutes after that and assisted one of our elderly wheelchair passengers who was becoming light-headed (outside temperatures were approaching 90 degrees Fahrenheit). The fire rescue personnel scanned the aircraft with their infrared/ thermal detection unit to ensure that nothing was burning inside the aircraft structure. ZZZ buses arrived immediately after the emergency personnel to provide transportation to passengers back to the terminal. Our Flight Attendants were exceptional in assisting with the evacuation. Most notably; FA 1 Name1 returned to the aircraft to retrieve ice and water for the passengers while they waited the few minutes for emergency personnel to arrive. First Officer Name2 was very efficient with remaining with the passengers and doing a head count before they boarded the buses at around XC00Z to ensure everyone was present and accounted for. FO Name2 remained with me and Maintenance at the aircraft. Operations Control and Maintenance Control called me at XC54Z to ask the details of our event as well as input the obligatory write- up in the AML (Aircraft Maintenance Logbook). Company Maintenance arrived at approximately XD15Z to assist with returning the aircraft to the terminal. FO Name2 and I worked with Name3 (ZZZ Company Maintenance) to power the aircraft back up and attempt to replicate our issue from earlier. Maintenance Control and Name3 said that our issue was most likely caused by the PACKS. After powering back up; the left PACK caused a 'L PACK DISCHARGE OVERTEMP/ TEMP CNTRL VLV1' caution as metal shavings started blowing out of the FOs side gasper vent. Name3 brought that PACK offline immediately. We all three assisted ZZZ Airport OPS and the tug in relocating the aircraft to Gate X; where passenger carry-on bags were offloaded.
