Narrative:The airplane was observed to pass from north to south under the Queen Isabel Causeway Bridge, which spanned between Port Isabel & South Padre Island, TX. After a 180 degree turn, it approached the bridge from south for another pass. However, during this pass, it struck a concrete bridge pylon & column, then descended uncontrolled into the water. No preimpact mechanical problem was found. The airplane's last annual inspection was dated 7/27/95. Neither of the pilot-rated occupants held a valid FAA medical certificate. Toxicology testing of the right seat occupant's blood revealed 0.006 mcg/ml tetrahydrocannabinol (active substance in marijuana), 0.006 mcg/ml tetrahydrocannabinol carboxylic acid (inactive metabolite of the active substance in marijuana), 0.087 mcg/ml cocaine, 1.809 mcg/ml benzoylecgonine (inactive metabolite of cocaine), and 0.095 mcg/ml diphenhydramine (a sedating over-the-counter antihistamine). Toxicology testing of the left seat occupant revealed cocaethylene (a substance formed when cocaine and alcohol are ingested at around the same time) in the liver fluid; 65 mg/dl ethanol in the vitreous fluid; and 143 mg/dl ethanol, 0.133 mcg/ml cocaine, and 0.066 mcg/ml benzoylecgonine in the blood. CAUSE: pilot impairment of judgment and performance due to alcohol and drugs, and failure of the pilot(s) to maintain obstacle clearance, during an intentional low altitude flight manueuver (low pass under a bridge).
