Narrative:
GPS approach. Passed missed approach because ground environment in sight, airport in sight. Executed circling approach, but due to cloud bank, went below circle minimums -- although technically VFR was still on IFR flight plan. Because of mountainous terrain, all quadrants chose to descend below minimums to keep airport in sight. Still above pattern altitude and still VFR, though. Judgement call which technically might have been an altitude bust.

Title: A MULTI ENG TURBOPROP AT ASE EXECUTES THE CIRCLE APCH AND RPTS CONFUSION AS TO WHEN HE CAN DSND FROM THE CIRCLE MDA.
Narrative: GPS APCH. PASSED MISSED APCH BECAUSE GND ENVIRONMENT IN SIGHT, ARPT IN SIGHT. EXECUTED CIRCLING APCH, BUT DUE TO CLOUD BANK, WENT BELOW CIRCLE MINIMUMS -- ALTHOUGH TECHNICALLY VFR WAS STILL ON IFR FLT PLAN. BECAUSE OF MOUNTAINOUS TERRAIN, ALL QUADRANTS CHOSE TO DSND BELOW MINIMUMS TO KEEP ARPT IN SIGHT. STILL ABOVE PATTERN ALT AND STILL VFR, THOUGH. JUDGEMENT CALL WHICH TECHNICALLY MIGHT HAVE BEEN AN ALT BUST.
