N157RC

On September 27, 2020, at 0703 Pacific daylight time (PDT), a Cessna T182T airplane, N157RC, was destroyed when it was involved in an accident near Santa Barbara, California. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot departed Santa Barbara Municipal Airport (SBA), Santa Barbara, California, for a cross-country flight to Truckee-Tahoe Airport (TRK), Truckee, California. According to radar data and voice communications provided by the Federal Aviation Administration, about 0701, the pilot contacted SBA tower requesting departure instructions. The local controller issued the pilot the wind information and a takeoff clearance from runway 15L. The pilot acknowledged the instructions.

When the airplane was approximately 0.5 nautical miles (nm) off the departure end of runway 15L, over the Pacific Ocean headed southbound, and at an altitude about 700 feet mean sea level (msl), the local controller instructed the pilot to contact departure control. The pilot acknowledged the instructions.

About 0702, as the airplane was at an altitude of 1,000 ft msl, the pilot contacted departure control. The departure controller established radar contact and instructed the pilot to turn right heading 255° and climb to 8,000 ft. The pilot acknowledged the instruction, and radar data indicated the airplane was at an altitude of 1,300 ft msl when a turn to the right (west) was initiated, followed by a turn to the north and a rapid descent.

About 0703, radar contact was lost, and the departure controller attempted to contact the pilot. No further transmissions were received from the pilot.

The Los Angeles County Sheriff’s Department Dive Unit located the pilot and airplane wreckage at a depth of approximately 200 ft on Thursday, October 1, 2020. The wreckage was recovered and examined at a secure facility. The examination revealed the fuselage and wings were separated into multiple segments and highly compressed.

Aileron control continuity was established from each flight control surface to the wing root where the cables were separated from tension overload. The cabin section of the aileron control cable system was not recovered. Elevator and rudder control continuity was established from the control surfaces to where the aft fuselage section was separated.

The aileron control yokes, rudder pedals, firewall instrument panel and engine were not recovered.

The fuel selector was observed in the BOTH position and both wing fuel tanks were breached.

According to fuel receipts provided by personnel at SBA, the pilot purchased 40 gallons of 100LL fuel on the morning of the accident.

The closest weather reporting station was an automated surface observing system (ASOS) located at Oxnard Airport (OXR), about 33 miles east-southeast of the accident location.

At 0651 PDT, the OXR ASOS reported wind from 060° at 4 knots, visibility of 7 statute miles, ceiling overcast at 1,400 ft, temperature 19° Celsius (C), dew point 17°C, and altimeter setting of 29.87 inches of mercury.

At the time of the accident, an airman's meteorological information (AIRMET) for instrument flight rules conditions in mist and fog was active for the accident location. Additionally, pilot reports made in the Los Angeles area within a few hours of the accident included references to instrument meteorological conditions between 1,400 and 2,000 ft.

According to the National Ocean and Atmospheric Administration, sunrise occurred at the accident location at 0651. At the time of the accident, the sun was about 1.9º above the horizon at an azimuth of 93º.

An autopsy of the pilot was performed by the Santa Barbara County Coroner, which listed the cause of death as “multiple traumatic injuries.” At the request of the coroner, Ascertain Forensics performed postmortem toxicological testing of spleen tissue from the pilot. This testing detected ethanol at 0.05 g/dL, and presumptively identified (without confirmation) ßphenylethylamine.

Toxicology testing performed at the FAA Forensic Sciences Laboratory detected ethanol at 0.024 g/dL in cavity blood and did not detect ethanol in urine (less than 0.001 g/dL).

Ethanol is a type of alcohol. It is the intoxicating alcohol in beer, wine, and liquor, and, if consumed, can impair judgment, psychomotor performance, cognition, and vigilance. However, consumption is not the only possible source of ethanol in postmortem specimens. Ethanol can be produced by microbes in a person’s body after death. ß-phenylethylamine is another substance that can be produced by microbes in a person’s body after death.

The FAA’s Airplane Flying Handbook (FAA-H-8083-3B) describes some hazards associated with flying when the ground or horizon are obscured. The handbook states, in part, the following:

The vestibular sense (motion sensing by the inner ear) in particular can and will confuse the pilot. Because of inertia, the sensory areas of the inner ear cannot detect slight changes in airplane attitude, nor can they accurately sense attitude changes that occur at a uniform rate over a period of time. On the other hand, false sensations are often generated, leading the pilot to believe the attitude of the airplane has changed when, in fact, it has not. These false sensations result in the pilot experiencing spatial disorientation.
