Narrative:
I was directed to work a combined radar position and be controller in charge. This was due to #1) limited staffing; and #2) to accommodate training in ground control. While working radar; I was vectoring aircraft X for a visual approach. The aircraft was heading 030 degrees and descended to 13000 ft MSL; approximately 10 mi southwest of dbl VOR. As controller in charge; I overheard backgnd conversation concerning LLWS. About this time; I also had a VFR cessna call me relaying that he was changing his destination to lxv. I informed the cessna that I had no prior information concerning him. I turned to the local controller (tower) and asked about LLWS. The local controller said 'yeah; aircraft Y had LLWS.' I then turned to the ground controller/flight data position (where training was taking place); to ensure that an appropriate ATIS concerning LLWS was being completed. As I refocused my attention to radar; I saw aircraft Y whom 'now' appeared on base leg. I had previously observed him go into coast on short final and I thought he had landed. I couldn't believe my eyes and I said to the local controller 'what's aircraft Y doing on base leg? I thought he had landed.' it was at this time that the local controller (very little experience) told me that it was aircraft Y who had 'gone around' as the result of an onboard windshear alert. Until this point; and having to ask several questions of both local control and ground control; I thought the initial LLWS report was from a previous aircraft Z departure. As I asked further questions; I began to realize that aircraft Y's go around might have fallen into the category of what would be considered an 'unusual go around;' which would warrant a 'Q' (quality assurance) entry on the daily facility log and; subsequent reporting procedures. In my immediate attempt to comply with these reporting procedures (a special interest item here in the past); gain all the facts; and notify the air traffic manager (atm) via the cabin attendant phone (to validate the quality assurance necessity of the log entry); I neglected to notice that aircraft X had entered ZDV's airspace (the eagle shelf) approximately 7 mi north of dbl VOR. I immediately called sector 6 for an after-the-fact pointout. I noticed that aircraft X was going in and out of coast due to his position and altitude (still at the appropriate MVA). I told aircraft X to turn right heading 180 degrees; then later to proceed direct dbl VOR. I then told aircraft X to turn right heading 210 degrees and report ase in sight. Aircraft X reported ase in sight and I subsequently cleared him for a visual approach. I compiled my nerves and thoughts; and asked ground control to terminate training and relieve me so I could report the possible operational deviation to the atm. Contributing factors/corrective actions: the radar position should not have to be combined with controller in charge as this puts the radar controller in a safety compromising situation as they have to #1) work their radar position and; #2) try to oversee the overall operation of the tower at the same time. This happens as the direct result of trying to accomplish training (pressure by management) with a low staffing level. Corrective action: have a standalone controller in charge whose duties oversee the tower operation so the radar controller can stay focused on their position.

Title: ASE APCH CTLR/CIC DESCRIBED OPDEV WHEN ACFT BEING VECTORED FOR VIS APCH ENTERED ZDV'S AIRSPACE WITHOUT COORD.
Narrative: I WAS DIRECTED TO WORK A COMBINED RADAR POS AND BE CIC. THIS WAS DUE TO #1) LIMITED STAFFING; AND #2) TO ACCOMMODATE TRAINING IN GND CTL. WHILE WORKING RADAR; I WAS VECTORING ACFT X FOR A VISUAL APCH. THE ACFT WAS HDG 030 DEGS AND DSNDED TO 13000 FT MSL; APPROX 10 MI SW OF DBL VOR. AS CIC; I OVERHEARD BACKGND CONVERSATION CONCERNING LLWS. ABOUT THIS TIME; I ALSO HAD A VFR CESSNA CALL ME RELAYING THAT HE WAS CHANGING HIS DEST TO LXV. I INFORMED THE CESSNA THAT I HAD NO PRIOR INFO CONCERNING HIM. I TURNED TO THE LCL CTLR (TWR) AND ASKED ABOUT LLWS. THE LCL CTLR SAID 'YEAH; ACFT Y HAD LLWS.' I THEN TURNED TO THE GND CTLR/FLT DATA POS (WHERE TRAINING WAS TAKING PLACE); TO ENSURE THAT AN APPROPRIATE ATIS CONCERNING LLWS WAS BEING COMPLETED. AS I REFOCUSED MY ATTN TO RADAR; I SAW ACFT Y WHOM 'NOW' APPEARED ON BASE LEG. I HAD PREVIOUSLY OBSERVED HIM GO INTO COAST ON SHORT FINAL AND I THOUGHT HE HAD LANDED. I COULDN'T BELIEVE MY EYES AND I SAID TO THE LCL CTLR 'WHAT'S ACFT Y DOING ON BASE LEG? I THOUGHT HE HAD LANDED.' IT WAS AT THIS TIME THAT THE LCL CTLR (VERY LITTLE EXPERIENCE) TOLD ME THAT IT WAS ACFT Y WHO HAD 'GONE AROUND' AS THE RESULT OF AN ONBOARD WINDSHEAR ALERT. UNTIL THIS POINT; AND HAVING TO ASK SEVERAL QUESTIONS OF BOTH LCL CTL AND GND CTL; I THOUGHT THE INITIAL LLWS RPT WAS FROM A PREVIOUS ACFT Z DEP. AS I ASKED FURTHER QUESTIONS; I BEGAN TO REALIZE THAT ACFT Y'S GAR MIGHT HAVE FALLEN INTO THE CATEGORY OF WHAT WOULD BE CONSIDERED AN 'UNUSUAL GAR;' WHICH WOULD WARRANT A 'Q' (QUALITY ASSURANCE) ENTRY ON THE DAILY FACILITY LOG AND; SUBSEQUENT RPTING PROCS. IN MY IMMEDIATE ATTEMPT TO COMPLY WITH THESE RPTING PROCS (A SPECIAL INTEREST ITEM HERE IN THE PAST); GAIN ALL THE FACTS; AND NOTIFY THE AIR TFC MGR (ATM) VIA THE CAB PHONE (TO VALIDATE THE QUALITY ASSURANCE NECESSITY OF THE LOG ENTRY); I NEGLECTED TO NOTICE THAT ACFT X HAD ENTERED ZDV'S AIRSPACE (THE EAGLE SHELF) APPROX 7 MI N OF DBL VOR. I IMMEDIATELY CALLED SECTOR 6 FOR AN AFTER-THE-FACT POINTOUT. I NOTICED THAT ACFT X WAS GOING IN AND OUT OF COAST DUE TO HIS POS AND ALT (STILL AT THE APPROPRIATE MVA). I TOLD ACFT X TO TURN R HDG 180 DEGS; THEN LATER TO PROCEED DIRECT DBL VOR. I THEN TOLD ACFT X TO TURN R HDG 210 DEGS AND RPT ASE IN SIGHT. ACFT X RPTED ASE IN SIGHT AND I SUBSEQUENTLY CLRED HIM FOR A VISUAL APCH. I COMPILED MY NERVES AND THOUGHTS; AND ASKED GND CTL TO TERMINATE TRAINING AND RELIEVE ME SO I COULD RPT THE POSSIBLE OPDEV TO THE ATM. CONTRIBUTING FACTORS/CORRECTIVE ACTIONS: THE RADAR POS SHOULD NOT HAVE TO BE COMBINED WITH CIC AS THIS PUTS THE RADAR CTLR IN A SAFETY COMPROMISING SITUATION AS THEY HAVE TO #1) WORK THEIR RADAR POS AND; #2) TRY TO OVERSEE THE OVERALL OP OF THE TWR AT THE SAME TIME. THIS HAPPENS AS THE DIRECT RESULT OF TRYING TO ACCOMPLISH TRAINING (PRESSURE BY MGMNT) WITH A LOW STAFFING LEVEL. CORRECTIVE ACTION: HAVE A STANDALONE CIC WHOSE DUTIES OVERSEE THE TWR OP SO THE RADAR CTLR CAN STAY FOCUSED ON THEIR POS.
