Introduction
An aircraft on a GPS 6 approach crashed, with wreckage located a few hundred feet from the runway. Trees near the runway threshold were broken at 15 feet above the runway elevation.
Approach Details
The flight was cleared for the GPS 6 approach. The published minimum descent altitude for this approach was 533 feet above the runway touchdown zone.
Mechanical Examination
Examination of the airframe, engine, vacuum pumps, and instruments revealed no evidence of malfunction or failure.
Toxicology Results
Forensic toxicology testing detected Tramadol in the pilot's blood at a concentration of 0.67 ug/mL, and Tramadol was also present in the urine. Tramadol is a prescription narcotic-like painkiller used for moderate to severe pain. The pilot was taking the drug for pain following back surgery.
Medical and Regulatory Issues
A review of FAA airman medical records found no evidence that the pilot reported the Tramadol usage to the FAA. Federal regulation 14 CFR Part 91.17 states that no person may act as a crewmember of a civil aircraft while using any drug that affects the person's faculties in any way contrary to safety.
