Aircraft; Procedure
Operating Part 121 Supplemental charter flight. While performing preflight paperwork with passengers on board 10 minutes prior to scheduled departure time; I received a phone call from Dispatch advising me not to depart due to the aircraft being under maintenance. Unbeknown to myself and my crew; I was advised that the Maintenance Director grounded the aircraft due to a discrepancy related to the windshield installed in the flight deck. No entry was found documented in the current aircraft logbook regarding prior maintenance performed on the windshield.Two [Part] 121 revenue flights were completed this flight day prior to being notified of a discrepancy with the aircraft.Passengers were deplaned and the aircraft was swapped with one located at remote parking.
SF340B Captain reported being advised just before departure that the aircraft was being grounded to a maintenance issue related to a cockpit window. Reporter stated the aircraft logbook did not reflect the discrepancy and the aircraft had already operated two flights earlier in the day.
