Narrative:
When I approached the aircraft for the first flight of the day, rain began to fall heavily. By the time I rounded up a gpu and ensured that the aircraft was fueled I was already pushing the departure time. I did a fast preflight (too fast) without my flashlight and missed the nose gear pin. We started the left and began starting the right when the ramper indicated to shut down because he noticed the flag in the nosewell. We shut down and both the captain and myself did a very thorough preflight and then proceeded with the flight. I can assure you that a more thorough preflight with flashlight in hand will be the procedure from here on. I won't let the elements and clock govern my preflight. Supplemental information from acn 410476: after receiving the aircraft, the first officer did preflight. I had briefed the flight attendant on the aircraft condition. She advised me on 3 write-ups. They were taken care of but it was now after departure time. In a hurry I failed to do a walkaround myself. While starting the second engine, a ramp person indicated that a gear pin was still installed in the nose gear. We shut down the engines and together, the first officer and myself, did another preflight that was much more thorough. If I had slowed down the pace of everything, I would have made time for my preflight. Then the whole occurrence would have never happened. The first officer will probably never miss such an obvious item again, and I will probably never miss my walkaround again.

Title: A BA4100 FLC OVERLOOKS THE NOSE GEAR DOWN LOCK PIN DURING THE PREFLT PROC. GND CREW PERSON SPOTS THE OMISSION DURING ENG START AND CREW PERFORMS ANOTHER PREFLT.
Narrative: WHEN I APCHED THE ACFT FOR THE FIRST FLT OF THE DAY, RAIN BEGAN TO FALL HEAVILY. BY THE TIME I ROUNDED UP A GPU AND ENSURED THAT THE ACFT WAS FUELED I WAS ALREADY PUSHING THE DEP TIME. I DID A FAST PREFLT (TOO FAST) WITHOUT MY FLASHLIGHT AND MISSED THE NOSE GEAR PIN. WE STARTED THE L AND BEGAN STARTING THE R WHEN THE RAMPER INDICATED TO SHUT DOWN BECAUSE HE NOTICED THE FLAG IN THE NOSEWELL. WE SHUT DOWN AND BOTH THE CAPT AND MYSELF DID A VERY THOROUGH PREFLT AND THEN PROCEEDED WITH THE FLT. I CAN ASSURE YOU THAT A MORE THOROUGH PREFLT WITH FLASHLIGHT IN HAND WILL BE THE PROC FROM HERE ON. I WON'T LET THE ELEMENTS AND CLOCK GOVERN MY PREFLT. SUPPLEMENTAL INFO FROM ACN 410476: AFTER RECEIVING THE ACFT, THE FO DID PREFLT. I HAD BRIEFED THE FLT ATTENDANT ON THE ACFT CONDITION. SHE ADVISED ME ON 3 WRITE-UPS. THEY WERE TAKEN CARE OF BUT IT WAS NOW AFTER DEP TIME. IN A HURRY I FAILED TO DO A WALKAROUND MYSELF. WHILE STARTING THE SECOND ENG, A RAMP PERSON INDICATED THAT A GEAR PIN WAS STILL INSTALLED IN THE NOSE GEAR. WE SHUT DOWN THE ENGS AND TOGETHER, THE FO AND MYSELF, DID ANOTHER PREFLT THAT WAS MUCH MORE THOROUGH. IF I HAD SLOWED DOWN THE PACE OF EVERYTHING, I WOULD HAVE MADE TIME FOR MY PREFLT. THEN THE WHOLE OCCURRENCE WOULD HAVE NEVER HAPPENED. THE FO WILL PROBABLY NEVER MISS SUCH AN OBVIOUS ITEM AGAIN, AND I WILL PROBABLY NEVER MISS MY WALKAROUND AGAIN.
