Narrative:

Mem airport, taxi out to temporary runway 17, northbound on taxiway north, broken-back hold bar extends out towards taxiway on intersection M9. Placement precludes turn towards runway from taxiway without possible incursion into protected runway environment. Pilot taxiing aircraft became distred by another aircraft approaching in opposite direction on same taxiway north. Mistook broken-back hold bar as CAT ii hold line due to close proximity to edge of taxiway and initiated a turn towards runway, with full intent of holding short of active runway. Before aircraft stopped safely, nose of aircraft crossed top of hold short bar by approximately 10-15 ft, depending upon angle of aircraft and hold line. No immediate conflict with another aircraft occurred. An aircraft approximately 4 mi out on a visual approach was directed to go around by ATC to ensure proper separation between aircraft, while encroaching aircraft was cleared from its position. Problem attributed to distraction of other approaching aircraft and insufficient situational awareness by taxiing pilot. Contributing factors: prior experience of being able to initiate turn from taxiway toward runway without impinging across hold short line. Corrective action: exercise more caution and vigilance with familiar airport layouts during times of construction.

Title: RWY INCURSION AS THE PIC OF AN MD88 TAXIES PAST THE BROKEN BACKED HOLD BAR BY RWY 17 AT MEM, TN.

Narrative: MEM ARPT, TAXI OUT TO TEMPORARY RWY 17, NBOUND ON TXWY N, BROKEN-BACK HOLD BAR EXTENDS OUT TOWARDS TXWY ON INTXN M9. PLACEMENT PRECLUDES TURN TOWARDS RWY FROM TXWY WITHOUT POSSIBLE INCURSION INTO PROTECTED RWY ENVIRONMENT. PLT TAXIING ACFT BECAME DISTRED BY ANOTHER ACFT APCHING IN OPPOSITE DIRECTION ON SAME TXWY N. MISTOOK BROKEN-BACK HOLD BAR AS CAT II HOLD LINE DUE TO CLOSE PROX TO EDGE OF TXWY AND INITIATED A TURN TOWARDS RWY, WITH FULL INTENT OF HOLDING SHORT OF ACTIVE RWY. BEFORE ACFT STOPPED SAFELY, NOSE OF ACFT CROSSED TOP OF HOLD SHORT BAR BY APPROX 10-15 FT, DEPENDING UPON ANGLE OF ACFT AND HOLD LINE. NO IMMEDIATE CONFLICT WITH ANOTHER ACFT OCCURRED. AN ACFT APPROX 4 MI OUT ON A VISUAL APCH WAS DIRECTED TO GO AROUND BY ATC TO ENSURE PROPER SEPARATION BTWN ACFT, WHILE ENCROACHING ACFT WAS CLRED FROM ITS POS. PROB ATTRIBUTED TO DISTR OF OTHER APCHING ACFT AND INSUFFICIENT SITUATIONAL AWARENESS BY TAXIING PLT. CONTRIBUTING FACTORS: PRIOR EXPERIENCE OF BEING ABLE TO INITIATE TURN FROM TXWY TOWARD RWY WITHOUT IMPINGING ACROSS HOLD SHORT LINE. CORRECTIVE ACTION: EXERCISE MORE CAUTION AND VIGILANCE WITH FAMILIAR ARPT LAYOUTS DURING TIMES OF CONSTRUCTION.
