Narrative:

The consequences are obvious when a crew member has an outside access door or hatch unlocked on an aircraft. Sometimes, an unlocked inside door can be just as important. We had just begun takeoff roll in srq when we heard our cockpit door slam open. We were equipped with the new enhanced security door, which is bullet proof and has an electronic locking system. A feature of the door is that it must be closed firmly to activate the lock. Our flight attendants are briefed to firmly close the door, then pull on the door knob to ensure a good lock. It is ultimately the captain's responsibility to make this happen. At pushback, when the flight attendant closed the door, I had not reminded her to pull on the door knob. Consequently, our cockpit was not secure. After the door opened, the jump seat flight attendant was able to slam it shut and we continued the takeoff. The rest of the flight went without incident. After this event, I plan to remind the flight attendants to pull on the door handle every time we push back, instead of relying on their memory. Fortunately, my failure in this instance had no disastrous results.

Title: B757-200 CREW HAD THE NEW 'FORTIFIED' COCKPIT DOOR COME OPEN ON TKOF.

Narrative: THE CONSEQUENCES ARE OBVIOUS WHEN A CREW MEMBER HAS AN OUTSIDE ACCESS DOOR OR HATCH UNLOCKED ON AN ACFT. SOMETIMES, AN UNLOCKED INSIDE DOOR CAN BE JUST AS IMPORTANT. WE HAD JUST BEGUN TKOF ROLL IN SRQ WHEN WE HEARD OUR COCKPIT DOOR SLAM OPEN. WE WERE EQUIPPED WITH THE NEW ENHANCED SECURITY DOOR, WHICH IS BULLET PROOF AND HAS AN ELECTRONIC LOCKING SYS. A FEATURE OF THE DOOR IS THAT IT MUST BE CLOSED FIRMLY TO ACTIVATE THE LOCK. OUR FLT ATTENDANTS ARE BRIEFED TO FIRMLY CLOSE THE DOOR, THEN PULL ON THE DOOR KNOB TO ENSURE A GOOD LOCK. IT IS ULTIMATELY THE CAPT'S RESPONSIBILITY TO MAKE THIS HAPPEN. AT PUSHBACK, WHEN THE FLT ATTENDANT CLOSED THE DOOR, I HAD NOT REMINDED HER TO PULL ON THE DOOR KNOB. CONSEQUENTLY, OUR COCKPIT WAS NOT SECURE. AFTER THE DOOR OPENED, THE JUMP SEAT FLT ATTENDANT WAS ABLE TO SLAM IT SHUT AND WE CONTINUED THE TKOF. THE REST OF THE FLT WENT WITHOUT INCIDENT. AFTER THIS EVENT, I PLAN TO REMIND THE FLT ATTENDANTS TO PULL ON THE DOOR HANDLE EVERY TIME WE PUSH BACK, INSTEAD OF RELYING ON THEIR MEMORY. FORTUNATELY, MY FAILURE IN THIS INSTANCE HAD NO DISASTROUS RESULTS.
