NTSB narrative
On July 13, 2009, at 0815 Coordinated Universal Time, a Gulfstream Aerospace G IV SP, VT-MST, registered to Asia Aviation Ltd, descended below the minimum safe altitude and flew near mountainous terrain in instrument meteorological conditions after departing from the Kerry Airport (EIKY), Farranfore, Ireland. The two crew members and passenger were not injured.
The AAIU requested an analysis of the pilot's forward windscreen which experienced a failure of the outboard glass ply.
An analysis of the windscreen was conducted at PPG Aerospace under the supervision of the National Transportation Safety Board. Analysis results were submitted to the Irish investigator-in-charge for consideration.
In addition, several sections of the outboard glass ply were swabbed for potential bird deoxyribonucleic acid (DNA). The samples were tested by the Smithsonian Institution's Feather Identification Lab which determined that bird DNA was not present.
This investigation is under the jurisdiction of the Government of Ireland. This report is for information purposes only and contains only information released by the Government of Ireland. Further information pertaining to his accident may be obtained from:

- 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: coordinates, damage. 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.
