Narrative:
Practicing stalls and recoveries with a student. During stall recovery process, flaps remained north down position. C152 power is not excessive and temporarily concerned about ability to hold altitude with full flaps on 80 degrees F day. Returned immediately for landing, requesting 'no delay,' but not declaring emergency from ith tower. Major concerns and things observed: 1) recommended 1500 ft AGL recovery could be too low if temperatures higher, and C152 not able to climb back up with full flaps. 2) how would an engine failure be handled with flaps full down if engine quit. 3) go around or aborted landing at airport not possible. 4) fortunately, ith is not a busy airport and request for priority handling was not needed -- we were the only airplane in the control area.

Title: C152 INSTRUCTOR, WITH STUDENT, HAD THE WING FLAPS STUCK IN THE FULL DOWN POS DURING PRACTICE STALL RECOVERY RESULTING IN A SUCCESSFUL EMER LNDG BACK AT HIS HOME BASE.
Narrative: PRACTICING STALLS AND RECOVERIES WITH A STUDENT. DURING STALL RECOVERY PROCESS, FLAPS REMAINED N DOWN POS. C152 PWR IS NOT EXCESSIVE AND TEMPORARILY CONCERNED ABOUT ABILITY TO HOLD ALT WITH FULL FLAPS ON 80 DEGS F DAY. RETURNED IMMEDIATELY FOR LNDG, REQUESTING 'NO DELAY,' BUT NOT DECLARING EMER FROM ITH TWR. MAJOR CONCERNS AND THINGS OBSERVED: 1) RECOMMENDED 1500 FT AGL RECOVERY COULD BE TOO LOW IF TEMPS HIGHER, AND C152 NOT ABLE TO CLB BACK UP WITH FULL FLAPS. 2) HOW WOULD AN ENG FAILURE BE HANDLED WITH FLAPS FULL DOWN IF ENG QUIT. 3) GAR OR ABORTED LNDG AT ARPT NOT POSSIBLE. 4) FORTUNATELY, ITH IS NOT A BUSY ARPT AND REQUEST FOR PRIORITY HANDLING WAS NOT NEEDED -- WE WERE THE ONLY AIRPLANE IN THE CTL AREA.
