In a letter to the editor, an aircraft crash resulting from possible aircrew intoxication caused by accidental release of RainBoe, a rain repellent, was described. A Boeing 767-200 crashed while landing at the International Airport in Guatemala City, Guatemala, an intermediate stop, on a flight from San Salvador, El Salvador to Los Angeles, California. The aircraft was destroyed, but the two pilots, seven flight attendants, and all 215 passengers were able to leave the plane safely, with only nine minor injuries. The accident was attributed to pilot error. An interview with the pilot and a review of the National Transportation Safety Board's report of the crash revealed that the pilot and copilot were experienced, rested, and operating on a familiar flight route. The crash occurred because just after the aircraft touched down, someone added 72% power, so the plane accelerated, went off the runway and stopped 810 feet away. Before the initial departure, the captain noticed the windshield rain repellent bottle in the cockpit was empty and asked for it to be refilled with RainBoe, a formulation containing freon-113(76131). After the bottle was refilled, a strange odor was noticed and liquid was seen coming from where the bottle was connected to the uptake apparatus. The spill was cleaned up and the defective bottle was replaced. All appeared to be normal, although fumes were still present in the cockpit and the odor, though less intense, was still noticeable. A review of the voice recorder indicated that the pilot's and copilot's voices were slow and mild, without excitement at the time the crash occurred. The author concludes that RainBoe fumes may have leaked into the cockpit during the flight and may have been involved in the crash.
