Narrative:

During takeoff we had a yaw damper and air data computer failure. Due to high gusty winds 190/18g29, the controls were extremely sensitive and difficult to control west/O the yaw damper. I had a full-time job flying the aircraft. First officer did the climb checklist which is normal procedure, but he failed to notice that the landing gear was still down. First officer also consulted emergency checklist when workload slowed down, but we could not get yaw damper on air data computer corrected. So we were both busy and failed to realize gear was still down until F/a came into cockpit and asked if we knew the gear was down (gear is visible from cabin). We put the gear up immediately. Gear down speed was never exceeded. Somehow with the combination of gusty winds and minor equipment failure we had failed to raise gear. I was at fault for missing gear up command and first officer was at fault for incorrectly doing climb checklist and missing the gear still being down.

Title: COMMUTER FLT CREW WITH ACFT EQUIPMENT PROBLEM FORGETS TO RAISE GEAR.

Narrative: DURING TKOF WE HAD A YAW DAMPER AND AIR DATA COMPUTER FAILURE. DUE TO HIGH GUSTY WINDS 190/18G29, THE CTLS WERE EXTREMELY SENSITIVE AND DIFFICULT TO CTL W/O THE YAW DAMPER. I HAD A FULL-TIME JOB FLYING THE ACFT. F/O DID THE CLB CHKLIST WHICH IS NORMAL PROC, BUT HE FAILED TO NOTICE THAT THE LNDG GEAR WAS STILL DOWN. F/O ALSO CONSULTED EMER CHKLIST WHEN WORKLOAD SLOWED DOWN, BUT WE COULD NOT GET YAW DAMPER ON AIR DATA COMPUTER CORRECTED. SO WE WERE BOTH BUSY AND FAILED TO REALIZE GEAR WAS STILL DOWN UNTIL F/A CAME INTO COCKPIT AND ASKED IF WE KNEW THE GEAR WAS DOWN (GEAR IS VISIBLE FROM CABIN). WE PUT THE GEAR UP IMMEDIATELY. GEAR DOWN SPD WAS NEVER EXCEEDED. SOMEHOW WITH THE COMBINATION OF GUSTY WINDS AND MINOR EQUIP FAILURE WE HAD FAILED TO RAISE GEAR. I WAS AT FAULT FOR MISSING GEAR UP COMMAND AND F/O WAS AT FAULT FOR INCORRECTLY DOING CLB CHKLIST AND MISSING THE GEAR STILL BEING DOWN.
