Aircraft; Human Factors; MEL; Procedure
Many factors played a part in the exceedance. 5 mel's and 1 cdl. We also had a limitation of FL250. Cleared 1 MEL before leaving gate. We were delayed and I switched aircraft in a hurry. I was doing IOE and he had never had restrictions like this. Weather was foggy and misty and icing conditions once airborne. Also light to moderate turbulence most of flight. It was night time and couldn't really see the sticker to remind us of limitation. It was late at night and we were both tired from being on duty for more than 9 hours at time.Plane had a CDL for right hand main landing gear door being removed. We were restricted to 250 kts. or .63 mach whichever less. We also had a pack deferred and 4 other MELs. So limited to FL250 as well. I was doing IOE and we were 3 hours delay when got to plane. Weather was low visibility and night time. By the time we were in cruise we realized that we had forgotten about the speed limitation for the landing gear. Arriving at gate in MLI; called Maintenance; and wrote up the exceedance. Don't be tired; or more focused on weather and fixated on other MEL of FL250.
ERJ First Officer reported that distraction related to aircraft MEL and CDL caused him to exceed a speed restriction.
