COLLINSVILLE Two pilots who died in a small-plane crash near Collinsville in September 2008 might have been impaired by prescription or over-the-counter medications, according to the National Transportation Safety Board.
But the federal agency still was not able to determine who was flying the Cessna 320.
The failure to maintain adequate airspeed was ruled the probable cause of the crash, according to an NTSB report issued Wednesday.
Harvey Hazelwood and Larry Jackson, an Oklahoma Highway Patrol captain, were flying buddies who lived at Airman Acres, which features a 2,650-foot private airstrip southwest of Collinsville.
Hazelwood, 55, was a private pilot and owned the aircraft, which he had been restoring. Jackson, 49, was a commercial pilot and had been an OHP pilot for nearly 20 years.
The toxicology testing was done by the Federal Aviation Administration's Toxicology Accident Research Laboratory in Oklahoma City.
Those findings of those tests were consistent with the three antidepressant medications Jackson was taking for medical conditions, according to the report.
Jackson had a history of hip pain, for which he was treated with nortriptyline. He was also taking fluoxetine, also known by the trade name Prozac, for post-traumatic stress disorder and trazodone for insomnia.
is possible that (Jackson) was impaired or distracted by his hip pain, or impaired by nortriptyline," the report says.
Jackson had performed numerous protective service missions for the Army Reserve, according to Jon Huntington, a retired Oklahoma State Bureau of Investigation agent with whom he attended warrant officer school.
Huntington said Jackson served in Romania and Iraq.
Toxicology results confirmed Hazelwood's use of diphenhydramine for allergy symptoms. The drug is an over-the-counter antihistamine that commonly causes drowsiness.
"It is likely that (Hazelwood) was impaired by recent ingestion of diphenhydramine," the report says.
Both men's use of medication was not noted in their most recent applications for airman medical certificates.
The crash occurred about 11:45 a.m. about a mile from the Airman Acres grass strip.
The report says the flight was the first Hazelwood had taken in the airplane since he bought it.
A witness at the air strip, who is an FAA-certified airframe and power plant mechanic, told officials that the airplane had a normal takeoff but that soon afterward he heard the engine whining.
As it prepared to make a left turn with its landing gear extended, the witness said, the airplane was "heading almost straight down (85 degrees) and the wings were rolling."
When the plane disappeared behind a tree line about a mile away, the witness knew that it had crashed, he told investigators.
Jackson was rated for and held a certified flight instructor certificate for single- and multiengine land and instrument airplanes. He had 2,000 flight hours.
