Narrative:
A routine dual instruction flight out of oak on 11/thu/89 was involved in a near miss when one aircraft on short final for 27R was cleared to land and another aircraft instructed to position and hold 27R at the same time. Xx, while in the east run-up area and monitoring tower frequency, heard the aircraft involved cleared to land 27R while still 5 mi out. Between that time and the time the aircraft was on short final, xx was told to position and hold 27R. Xx, while positioned over the threshold markings of 27R, noticed an air carrier jet about to cross 27L at taxiway bravo. To avoid the jet blast, we rolled forward of our position. Apparently our motion made us more visible as we soon heard the aircraft on short final announce he was going around due to aircraft rolling on 27R. Seconds later he came into view of xx, about 75' overhead: cause of problem: controller work overload--he simply forgot he cleared aircraft to land when he told xx to position and hold. Solution proposal: don't clear to land so far out.

Title: CONFLICT BETWEEN SMA HOLDING IN POSITION FOR TKOF AND ACFT ON FINAL APCH TO SAME RWY RESULTING IN GO AROUND BY APCH ACFT.
Narrative: A ROUTINE DUAL INSTRUCTION FLT OUT OF OAK ON 11/THU/89 WAS INVOLVED IN A NEAR MISS WHEN ONE ACFT ON SHORT FINAL FOR 27R WAS CLRED TO LAND AND ANOTHER ACFT INSTRUCTED TO POS AND HOLD 27R AT THE SAME TIME. XX, WHILE IN THE E RUN-UP AREA AND MONITORING TWR FREQ, HEARD THE ACFT INVOLVED CLRED TO LAND 27R WHILE STILL 5 MI OUT. BTWN THAT TIME AND THE TIME THE ACFT WAS ON SHORT FINAL, XX WAS TOLD TO POS AND HOLD 27R. XX, WHILE POSITIONED OVER THE THRESHOLD MARKINGS OF 27R, NOTICED AN ACR JET ABOUT TO CROSS 27L AT TXWY BRAVO. TO AVOID THE JET BLAST, WE ROLLED FORWARD OF OUR POS. APPARENTLY OUR MOTION MADE US MORE VISIBLE AS WE SOON HEARD THE ACFT ON SHORT FINAL ANNOUNCE HE WAS GOING AROUND DUE TO ACFT ROLLING ON 27R. SECS LATER HE CAME INTO VIEW OF XX, ABOUT 75' OVERHEAD: CAUSE OF PROB: CTLR WORK OVERLOAD--HE SIMPLY FORGOT HE CLRED ACFT TO LAND WHEN HE TOLD XX TO POS AND HOLD. SOLUTION PROPOSAL: DON'T CLR TO LAND SO FAR OUT.
