Windshield heating faulty on all 747, 757, 767 and 777 aircraft

7 days ago a 757 windscreen shattered:

US investigators are urging the FAA to pass long-delayed directives to fit redesigned windshield-heating systems on Boeing aircraft after the latest in a series of smoke and fire incidents resulted in an American Airlines Boeing 757 windshield’s shattering in flight.

The first officer`s windscreen heater caught fire and shattered the glass and smoke filled the cockpit - the worrything is that this should have been dealt with 4 years ago :O

WOW! how weirdly coincidental.

I was looking just a few hours ago at a port side 707 cockpit window that had a failure in its heater element. You could clearly see where the heater element had over heated and the end result was that the inch thick laminate cracked into dozens of pieces from the cold shock and airframe stresses upon landing. Seems this problem may be much older than some would think as the window I was looking at was an instructional article that cracked quite some years ago.

LEE.

Has been a known issue for years.

That is why the heater block connector must be inspected regulary, as it will show signs of overheating long time before it fails.
