From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.4)No record was found of the pilot obtaining a preflight or in-flight weather briefing. An AIRMET valid during the period of the flight forecasted mountain obscuration and IFR conditions in the accident area. The instrument rated pilot flew a visual flight rules (VFR) cross-country flight over mountainous terrain in marginal weather conditions. The aircraft collided with a coastal mountain ridge at the 1,940 foot level; the coastal mountain range was the last terrain feature before the pilot's destination. Review of the pilot's logbook revealed he lacked the recency of experience to fly in instrument meteorological conditions (IMC) under instrument flight rules (IFR). The accident site was obscured by low ceilings during the accident time and subsequently impeded search and rescue operations. Toxicology tests of the pilot's blood and urine detected theophylline (a drug commonly used to treat asthma) at levels of 2.2 mcg/ml and 22.5 mcg/ml, respectively. Also, undetermined levels of ephedrine and phenylopropanolamine (over-th-counter decongestants) were detected in his blood and urine, and an undetermined level of hydrochlorothiazide (a drug commonly used to treat high blood pressure) was detected in his blood.

As the FAA filed it

(.4)NO RECORD WAS FOUND OF THE PILOT OBTAINING A PREFLIGHT OR IN-FLIGHT WEATHER BRIEFING. AN AIRMET VALID DURING THE PERIOD OF THE FLIGHT FORECASTED MOUNTAIN OBSCURATION AND IFR CONDITIONS IN THE ACCIDENT AREA. THE INSTRUMENT RATED PILOT FLEW A VISUAL FLIGHT RULES (VFR) CROSS-COUNTRY FLIGHT OVER MOUNTAINOUS TERRAIN IN MARGINAL WEATHER CONDITIONS. THE AIRCRAFT COLLIDED WITH A COASTAL MOUNTAIN RIDGE AT THE 1,940 FOOT LEVEL; THE COASTAL MOUNTAIN RANGE WAS THE LAST TERRAIN FEATURE BEFORE THE PILOT'S DESTINATION. REVIEW OF THE PILOT'S LOGBOOK REVEALED HE LACKED THE RECENCY OF EXPERIENCE TO FLY IN INSTRUMENT METEOROLOGICAL CONDITIONS (IMC) UNDER INSTRUMENT FLIGHT RULES (IFR). THE ACCIDENT SITE WAS OBSCURED BY LOW CEILINGS DURING THE ACCIDENT TIME AND SUBSEQUENTLY IMPEDED SEARCH AND RESCUE OPERATIONS. TOXICOLOGY TESTS OF THE PILOT'S BLOOD AND URINE DETECTED THEOPHYLLINE (A DRUG COMMONLY USED TO TREAT ASTHMA) AT LEVELS OF 2.2 MCG/ML AND 22.5 MCG/ML, RESPECTIVELY. ALSO, UNDETERMINED LEVELS OF EPHEDRINE AND PHENYLOPROPANOLAMINE (OVER-TH-COUNTER DECONGESTANTS) WERE DETECTED IN HIS BLOOD AND URINE, AND AN UNDETERMINED LEVEL OF HYDROCHLOROTHIAZIDE (A DRUG COMMONLY USED TO TREAT HIGH BLOOD PRESSURE) WAS DETECTED IN HIS BLOOD.
