Aircraft
After takeoff; received a Number 2 Engine Bleed Leak.  Complied with QRH.  On approach approximately 5;000 feet; ECAM notified us of the Lower Access Panels being open.   We both thought that the bleed leak could be related to the panel light.  Perhaps a fire.  We declared an emergency just to be safe.  Completed all checklists and landed uneventfully.  Came to a stop on the runway where the fire trucks were waiting for us.  We shut down the second engine and they inspected us for any fire.  After they confirmed we were not on fire; we taxied to the gate.    After we exited the aircraft; we checked the access panels and found the handle was dislodged and open; where it should have been flat and stowed.I think the bleed leak and the panel were two separate things and don't relate to each other.  No way to really prevent it.
[This report contains no additional information.]
An A310 number two engine BLEED LEAK ECAM alerted; so they complied with the checklist; declared an emergency; and returned to landing. During the return; a LOWER ACCESS panel door light ECAM alerted; but the crew determined after landing the two ECAMs were not related.
