Narrative:

Air carrier Y (B737) rolling out on runway 4R, to clear at taxiway east, cross runway 4L and runway 8L. Small transport X (PA23) on final to runway 4L. Air carrier Y crossed runway 4L as small transport X flaring for landing. Aircraft not initially observed due to factors affecting controller workload, ie, major runway closure (runway 8L). All traffic diverted to runways 4L&right for arrs. Preceding aircraft, a PA28, reported an open door. PA28 was given control instructions to re-enter traffic pattern. PA28 was issued traffic to follow, small transport X, reported traffic in sight. In addition, tour helicopter was approaching over main terminal for crossing runway 8L, runway 4L, and runway 4R. Due to close proximity, attention was diverted to assist the PA28 in possible distress. Small transport X may have executed a short approach without local controller's knowledge. Small transport X was last observed entering downwind nne of airport.

Title: ATCT LCL CTLR CLRED AN ACR B737 TO CROSS RWY 4L AND RWY 8L ON TXWY E AFTER LNDG ROLLOUT. CTLR DISTR BY ANOTHER ACFT WITH A PROB AND A HELI WANTING TO CROSS ARPT AND WHEN HE RETURNED SCAN TO RWYS, SAW THE B737 XING RWY 4L AS A PA23 WAS FLARING FOR LNDG ON THE RWY.

Narrative: ACR Y (B737) ROLLING OUT ON RWY 4R, TO CLR AT TXWY E, CROSS RWY 4L AND RWY 8L. SMT X (PA23) ON FINAL TO RWY 4L. ACR Y CROSSED RWY 4L AS SMT X FLARING FOR LNDG. ACFT NOT INITIALLY OBSERVED DUE TO FACTORS AFFECTING CTLR WORKLOAD, IE, MAJOR RWY CLOSURE (RWY 8L). ALL TFC DIVERTED TO RWYS 4L&R FOR ARRS. PRECEDING ACFT, A PA28, RPTED AN OPEN DOOR. PA28 WAS GIVEN CTL INSTRUCTIONS TO RE-ENTER TFC PATTERN. PA28 WAS ISSUED TFC TO FOLLOW, SMT X, RPTED TFC IN SIGHT. IN ADDITION, TOUR HELI WAS APCHING OVER MAIN TERMINAL FOR XING RWY 8L, RWY 4L, AND RWY 4R. DUE TO CLOSE PROX, ATTN WAS DIVERTED TO ASSIST THE PA28 IN POSSIBLE DISTRESS. SMT X MAY HAVE EXECUTED A SHORT APCH WITHOUT LCL CTLR'S KNOWLEDGE. SMT X WAS LAST OBSERVED ENTERING DOWNWIND NNE OF ARPT.
