Narrative:
American Airlines flight 1738, a Boeing 757-200, declared an emergency due to smoke in the cockpit and diverted to Palm Beach International Airport (KPBI), West Palm Beach, Florida. The flight was being piloted by an airline transport pilot certificated captain and airline transport pilot certificated first officer. The airplane landed without incident at KPBI. Night visual meteorological conditions prevailed at the time of the incident. The scheduled domestic passenger flight was being conducted under the provisions of Title 14 CFR Part 121, and an instrument flight rules flight plan had been filed. The captain, first officer, three of the six flight attendants, and one passenger were transported to the hospital with minor injuries. The flight departed San Juan, Puerto Rico, at 1851 atlantic standard time and was enroute to Philadelphia, Pennsylvania.

According to the flight crew, the airplane was at flight level (FL) 340, approximately 35 miles south of the DRIBL intersection on radial R763, when they noticed a burning odor and large amounts of smoke in the cockpit, none of it coming from an obvious place. The crew donned their oxygen masks and smoke goggles, declared an emergency, and turned the airplane westbound towards the Florida coast. They accomplished the Quick Reference Handbook procedures for "Smoke/Fumes Removal". While trying to determine the source of the smoke, the first officer noticed that his windshield began to crack and small shards of glass began to separate and strike him. They began a descent and about 10,000 feet the first officer's windshield made a "very loud bang" and shattered, blocking all outside visibility. The airplane landed on Runway 27R and taxied to the gate under its own power.
The National Transportation Safety Board determines the probable cause(s) of this incident to be:
The arcing of the windshield heat system at the upper, aft (J1) and upper, forward (J4) terminal locations on the first officer's windshield, which caused the inner pane of glass to fracture.
