## Analysis

CROSBY MUNICIPAL ARPT WAS NOTAM'D CLOSED DUE TO RWY CONSTRUCTION AND RESURFACING. THE PLT AND PAXS WERE EMPLOYEES OF THE ENGINEERING COMPANY PARTICIPATING IN THE ARPT CONSTRUCTION. THE PLT OF N8271P HAD LANDED ON THE CLOSED RWY EARLIER IN THE DAY. THE RWY WAS OCCUPIED BY TWO 3-TON DUMP TRUCKS AND PAVING EQUIPMENT. THE PLT WAS SHOWN A GRASS STRIP THAT WAS SUITABLE FOR TAKEOFF BUT CHOSE THE PAVED RWY. THE ACFT STRUCK THE PAVING EQUIPMENT THAT WAS APPROX 1440 FT FROM THE NEW TAXIWAY USED BY N8271P TO ACCESS RWY 30.
