Narrative:

On takeoff at lga we sustained major windshield damage. This was caused by a combination of 2 factors. One was that the wind was very gusty. The other was an air carrier B757 that had just exited runway 31 on the highspd taxiway. That aircraft was clear of the runway, but had not taxied onto the ramp area. His exhaust was angled toward aircraft departing runway 31. We were issued a takeoff clearance and started our roll. When we reached a point abeam the highspd taxiway, the B757 must have increased his power resulting in debris (pebbles, small stones, etc, that were alongside the taxiway) being blown in our direction. The gusty winds also coming from that direction aided in causing damage. The immediate result was a badly cracked left side windshield and a windshield heat failure alert. I did not want to continue the flight at altitude with this situation and chose to divert to ewr for repairs and damage inspection by ewr maintenance. No emergency was declared and the flight landed without further difficulty.

Original NASA ASRS Text

Title: A FOKKER 100 DIVERTED AFTER TKOF DUE TO ENCOUNTERING JETBLAST DURING TKOF WHICH CONTAINED STONES AND PEBBLES FROM A TAXIING B757 CAUSING WINDSHIELD DAMAGE.

Narrative: ON TKOF AT LGA WE SUSTAINED MAJOR WINDSHIELD DAMAGE. THIS WAS CAUSED BY A COMBINATION OF 2 FACTORS. ONE WAS THAT THE WIND WAS VERY GUSTY. THE OTHER WAS AN ACR B757 THAT HAD JUST EXITED RWY 31 ON THE HIGHSPD TXWY. THAT ACFT WAS CLR OF THE RWY, BUT HAD NOT TAXIED ONTO THE RAMP AREA. HIS EXHAUST WAS ANGLED TOWARD ACFT DEPARTING RWY 31. WE WERE ISSUED A TKOF CLRNC AND STARTED OUR ROLL. WHEN WE REACHED A POINT ABEAM THE HIGHSPD TXWY, THE B757 MUST HAVE INCREASED HIS PWR RESULTING IN DEBRIS (PEBBLES, SMALL STONES, ETC, THAT WERE ALONGSIDE THE TXWY) BEING BLOWN IN OUR DIRECTION. THE GUSTY WINDS ALSO COMING FROM THAT DIRECTION AIDED IN CAUSING DAMAGE. THE IMMEDIATE RESULT WAS A BADLY CRACKED L SIDE WINDSHIELD AND A WINDSHIELD HEAT FAILURE ALERT. I DID NOT WANT TO CONTINUE THE FLT AT ALT WITH THIS SIT AND CHOSE TO DIVERT TO EWR FOR REPAIRS AND DAMAGE INSPECTION BY EWR MAINT. NO EMER WAS DECLARED AND THE FLT LANDED WITHOUT FURTHER DIFFICULTY.
