Narrative:

During an instructional flight in the pattern at tix, student and I were doing engine out patterns and lndgs. The student was given an engine failure at midfield downwind when he selected the gear to the down position. Maneuvering the aircraft around the pattern with 2 other aircraft, the student was performing the recommended gump checks. In a position to land I, the instrument, noticed no indication of the gear being down and locked. I initiated a go around and during the go around around the left propeller struck the ground approximately 2'. During the go around, gear selection was evident in the up and then down selection to land. The 5 amp circuit breaker had popped, and when reset, extended the landing gear and I landed and shut down. The respective individuals at the flight school were notified. Being an instructional flight in the turn and the single engine work, cockpit duties were many. Letting the student perform the respective gump and me not verifying the gump check initially helped the problem continue to a critical time. Also no backup from the gear unsafe light and horn kept my attention to a minimum in respect to the gear, but not to the flying. Ultimately, I did to my verification of the landing confign, but was too late.

Title: GEAR FAILED TO EXTEND AND PROPELLER TOUCHED RWY DURING GO AROUND.

Narrative: DURING AN INSTRUCTIONAL FLT IN THE PATTERN AT TIX, STUDENT AND I WERE DOING ENG OUT PATTERNS AND LNDGS. THE STUDENT WAS GIVEN AN ENG FAILURE AT MIDFIELD DOWNWIND WHEN HE SELECTED THE GEAR TO THE DOWN POS. MANEUVERING THE ACFT AROUND THE PATTERN WITH 2 OTHER ACFT, THE STUDENT WAS PERFORMING THE RECOMMENDED GUMP CHKS. IN A POS TO LAND I, THE INSTR, NOTICED NO INDICATION OF THE GEAR BEING DOWN AND LOCKED. I INITIATED A GAR AND DURING THE GAR AROUND THE LEFT PROP STRUCK THE GND APPROX 2'. DURING THE GAR, GEAR SELECTION WAS EVIDENT IN THE UP AND THEN DOWN SELECTION TO LAND. THE 5 AMP CB HAD POPPED, AND WHEN RESET, EXTENDED THE LNDG GEAR AND I LANDED AND SHUT DOWN. THE RESPECTIVE INDIVIDUALS AT THE FLT SCHOOL WERE NOTIFIED. BEING AN INSTRUCTIONAL FLT IN THE TURN AND THE SINGLE ENG WORK, COCKPIT DUTIES WERE MANY. LETTING THE STUDENT PERFORM THE RESPECTIVE GUMP AND ME NOT VERIFYING THE GUMP CHK INITIALLY HELPED THE PROB CONTINUE TO A CRITICAL TIME. ALSO NO BACKUP FROM THE GEAR UNSAFE LIGHT AND HORN KEPT MY ATTN TO A MINIMUM IN RESPECT TO THE GEAR, BUT NOT TO THE FLYING. ULTIMATELY, I DID TO MY VERIFICATION OF THE LNDG CONFIGN, BUT WAS TOO LATE.
