NTSB narrative
The crew had just selected the windshield heat on, when smoke began to fill the airplane. After the windshield heat was turned off the smoke subsided. The flightcrew declared an emergency, and made an emergency evacuation of the airplane after landing. Postflight examination of the airplane revealed that electrical arcing was occurring on the copilots windshield at the low power heating element's terminal block. Additional testing revealed that the chemicals used to bond the terminal block during the windshield's manufacture had recently been changed due to EPA regulations, and were incompatible with the braided wire in the windshield.
Probable cause
the materials used in the new windshield, to meet new EPA requirements, were inadequate for the design.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
