The data for this study was from 1353 pilots who died from 2004 to 2008, most from general aviation accidents. The majority of the pilots held a third-class medical certicate. Drugs or medications were found from 42% of pilots tested, being Diphenhydramine (an H1 antihistimine with impairing properties) the most common. The FAA has taken steps to warn pilots of the dangers in using this medication that can be dispensed as both a prescription and over the counter. A 7% of pilots were found alcohol levels above FAA limit. Interesting thecnical report advisable for the AME’s -aviation medical examiners- who issue medical certicates for priveta pilots
