Since accident investigators could find no indication of mechanical trouble that might have caused the 182 to go down at Monroe, that accident, too, appeared to have been a simple case of disorientation, distraction or misreading of the altimeter. As is so often true, it's hard to understand, when you're sitting at home reading about it, how such disorientation takes place. The pilot, although not current, had logged 35 instrument approaches in the past two years and two, not counting those on the night of the accident, in the past six months. He should not have been as rusty as his performance on the first two practice approaches suggests that he was. An autopsy revealed that the pilot was taking Zoloft, a prescription antidepressant that would have disqualified him from flying had a medical examiner known that he was taking it. The NTSB's report on the accident, however, did not include the medication in the list of contributing factors.
