Narrative:
In the morning, aircraft xyz (B737-300) departed the gate for the first flight of the day. While taxiing to the runway a panel was observed on the taxiway. Approximately 6 aircraft were called back to the terminal for a quick inspection. Aircraft xyz was missing a lower l-hand center boost pump access panel. A new one was installed, a logbook write-up was made and the aircraft departed after a 64 min delay. The aircraft had a hangar visit that previous night. All boost pump access panels were removed and reinstalled to check pin numbers and serial numbers of pumps. I don't know if the panel was maybe broken upon installation or just not properly locked down. I rushed through the installation of the panels to help my crew with another aircraft that we were short handed on. I should have taken a second look at the panels to confirm the correct lock alignment marks and security of the panels. Although the taxi from hangar to the terminal revealed no problems.
