Narrative: Last leg of a 4 day and last leg of a 5 leg day. Showtime that morning of XA:30 am. And a LINE CHECK! Thunderstorms the entire day; deviating; normal ER issues with weight. Upon departing DAL we were giving the JOE POOL departure in the PDC. It states DEPARTING RUNWAY 31R Climb on heading 310 until the ILVF or IOVW localizer 5.5 DME; than right turn heading 010. The CA asked if I was ready for the turn in which I said yes as I was hand flying and looking down at the chart. He wanted the initial heading verified in which I did. The check airman said nothing. We made the turn and ATC queried us about the turn and stated we were supposed to be runway heading. We were than giving a number to call. We did brief the departure; put it the appropriate frequency for DME and discuss the initial turn at 5.5 DME. I will say that on our initial push back we were notified of a ground stop and returned to the gate and shut down the aircraft. I do not remember double checking the correct frequency when we started the aircraft up again the second time but I am assuming it did not change. Upon talking to the Tower it was said that there had been 4 deviations on the JOE POOL on this same day by our company. I found that to be odd. We failed the line check are suspended from further flying. Pairings of this nature should not even exist. It was only thanks to a ground stop in DAL that we were able to eat. The main potential threat for me was fatigue due to the many series of events on every single flight. I was exhausted. I have learned that it is ok to call in fatigued even in the face of a LINE CHECK. For at the end of the day; it is you who will be judged and appropriate actions will be taken if you are not at the top of your game. Rightfully so.


Second narrative: The morning started with a XX:30 am wake up and XA:20 van ride for a XA:30 show. We departed on time at XB:30. There was no food or breakfast available prior to departure because everything was closed. We arrived for a quick turn and again crew had no time to eat prior to next flight. After another quick turn in and out; we arrived into DAL. By this time it was approximately XK:00 pm and no crew member had eaten a single thing . When the fight was delayed for a ground stop; I returned to the gate and allowed crew time to eat. Flight to DAL was a line check and was conducted satisfactorily. The next flight; another Line CK; started with Joe Pool 5 Non RNAV departure. The departure directed at 5.5 DME on LOC freq. to turn to 010 Hdg. During climb; at 5.5 DME I called out '5.5 DME turning 010'. FO then stated it was to be 100 Hdg. I verified before turning it was 010 and turned Hdg bug to 010. Check Airman said nothing. After contacting Departure; Controller stated we had turned early and gave a phone number to contact. After flight; I contacted the Tower and he stated there had been 4 deviations on the Joe Pool 5 departure Runway 31R 'That Day'. [We] failed the Line Check. Myself and FO are now suspended from further flying. Thunderstorms were surrounding the airports. I also strongly feel that not having adequate time to eat during the course of the day was a contributing factor.


Synopsis: EMB145 flight crew reports turning early to heading 010 on the JPOOL5 departure from Runway 31R at DAL while receiving a line check. The turn was to be initiated at 5.5 DME and the Captain apparently mistook 3.3 for 5.5 and called for the turn. Fatigue was cited as a factor by all three crew members involved.
