Narrative:

We reported an oil leak to maintenance. They came out and said it was within limits. As they were fixing it, a deadheading crew member (who was flying the aircraft back was doing a preflight). Well we took off and had an uneventful trip to jln. As we were taxiing in to get parked they were pointing toward the engine nacelle. After we stopped, I asked the ground crew what they were staring at. They said the oil dipstick door was open. My guess is maintenance never secured the door. I asked the deadheading crew member if she didn't latch it. She said she didn't check it because maintenance was looking at it. So either maintenance didn't latch it or it just popped open during flight. I assumed since the deadheading crew walked around the aircraft everything was ok, but I should have checked the maintenance work myself to make sure it was done properly.

Title: BA32 CREW FOUND AN OIL ACCESS DOOR OPEN ON ARR.

Narrative: WE RPTED AN OIL LEAK TO MAINT. THEY CAME OUT AND SAID IT WAS WITHIN LIMITS. AS THEY WERE FIXING IT, A DEADHEADING CREW MEMBER (WHO WAS FLYING THE ACFT BACK WAS DOING A PREFLT). WELL WE TOOK OFF AND HAD AN UNEVENTFUL TRIP TO JLN. AS WE WERE TAXIING IN TO GET PARKED THEY WERE POINTING TOWARD THE ENG NACELLE. AFTER WE STOPPED, I ASKED THE GND CREW WHAT THEY WERE STARING AT. THEY SAID THE OIL DIPSTICK DOOR WAS OPEN. MY GUESS IS MAINT NEVER SECURED THE DOOR. I ASKED THE DEADHEADING CREW MEMBER IF SHE DIDN'T LATCH IT. SHE SAID SHE DIDN'T CHK IT BECAUSE MAINT WAS LOOKING AT IT. SO EITHER MAINT DIDN'T LATCH IT OR IT JUST POPPED OPEN DURING FLT. I ASSUMED SINCE THE DEADHEADING CREW WALKED AROUND THE ACFT EVERYTHING WAS OK, BUT I SHOULD HAVE CHKED THE MAINT WORK MYSELF TO MAKE SURE IT WAS DONE PROPERLY.
