What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft with three persons on board, two pilots and one cabin attendant, departed William p. Hobby airport (khou), TX enroute fort lauderdale executive airport (kfxe), FL. In climb phase of flight, briefly leveling off at FL 350 waiting to climb to final altitude of FL 410, crew heard a loud “bang” noise. Pilots did not observe any abnormal engine indications. The vibration sensors showed no evidence of abnormal indications. Pilot initially believed they may have experienced a compressor stall. Because they had just flown through ice, pilot believed a compressor stall may have been induced by one of the engines ingesting ice. Pilot walked back to cabin to inspect engine nacelles to see if there was any ice buildup. As pilot approached the right-side windows, pilot noticed the outside panel of the passenger-side window had blown out. Pilot returned to the cockpit and discussed the problem with the crew. ATC was contacted and advised of the situation and aircraft was turned around to return to hou. As aircraft had no abnormal indications, engines were operating normally, pressurization system functioning properly and all flight controls functioning properly, pilot chose to not declare an emergency. The return flight to hou was uneventful and the aircraft landed safely. Upon exiting the aircraft, crew observed a dent on the engine nacelle and several fan blades that had dents indicating the window had entered engine number two.
