Accident Details
Probable Cause and Findings
The pilot’s failure to maintain adequate airspeed, which resulted in an aerodynamic stall and spin. Contributing to the accident was the failure of the pilot to perform an adequate preflight inspection, to include removal of the pitot tube cover.

Analysis
HISTORY OF FLIGHTOn June 18, 2021, about 1357 central daylight time, a Cirrus SR20 airplane, N62WR, was destroyed when it was involved in an accident at Conway Regional Airport (CXW), Conway, Arkansas. The pilot, who was the sole occupant, sustained fatal injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
A witness reported that after the airplane departed runway 22 at CXW, he heard a transmission over the Universal Integrated Communications (UNICOM) frequency that stated, “six-two whiskey romeo emergency landing runway 2.” There is no runway 2 at CXW. Shortly thereafter, he observed the accident airplane make a left turn and overfly runway 4 and stated that the airplane appeared “crazy fast.” After the airplane overflew runway 4, it entered a steep left bank, made 1 1/2 rotations and then impacted the ground.
Recovered GPS data from the airplane revealed that the highest altitude achieved on the flight was 593 ft above ground level (agl) when the airplane was on a crosswind leg in the traffic pattern. The airplane then began a continuous descent until impact. The downwind leg was flown about 0.1 nautical mile south of the runway (see figure 1).

WRECKAGE AND IMPACT INFORMATIONThe airplane impacted the ground in a nose-low, inverted attitude. The right wing was fractured, and pieces of the wing were located in the initial ground scar. Propeller slash marks were found in the ground near the initial impact point and contained white paint transfer signatures (see figure 2). The propeller blades were found fractured and separated from the crankshaft flange.

Fragments of windscreen were found in the vicinity of the propeller. During the impact sequence, the Cirrus Airframe Parachute System (CAPS) deployed, and the canopy was found still bundled in a straight line away from the wreckage. The total debris field from the CAPS rocket to the main wreckage was about 110 ft. A postaccident examination revealed the pitot tube cover remained secured on the pitot tube with a “REMOVE BEFORE FLIGHT” banner attached (see figure 3).

ADDITIONAL INFORMATIONThe Cirrus Design SR20 Pilot’s Operating Handbook contained a description for the conduct of a preflight inspection under the normal procedures section. That procedure contained the following:

b. Pitot Mast (underside) ................. Cover Removed, Tube Clear
MEDICAL AND PATHOLOGICAL INFORMATIONFederal Aviation Administration (FAA) Forensic Sciences Laboratory toxicology testing detected the antidepressant bupropion at 6,618 nanograms per milliliter (ng/mL) and its metabolite hydroxybupropion at 444 ng/mL in the pilot’s cavity blood. The mood stabilizing medication lamotrigine was detected in his cavity blood at 2,134 ng/mL. All three compounds were also detected in his urine.
Bupropion is a medication prescribed as an antidepressant (commonly marketed as Wellbutrin) or for smoking cessation (commonly marketed as Zyban). Hydroxybupropion is the major active metabolite of bupropion. The treatment of depression would require FAA review before flying, and bupropion is not one of the drugs that FAA will permit use for depression. According to the FAA, bupropion carries the warning that the medication may impair mental or physical ability required to perform hazardous tasks.
Lamotrigine is a prescription medication indicated for treatment of bipolar disorder and adjunctive treatment of epilepsy. It is commonly marketed as Lamictal. Lamotrigine can have impairing performance effects including dizziness and drowsiness, and patients should be warned not to operate complex machinery while on the medication.
One record was obtained from the healthcare provider who completed the pilot’s BasicMed form on January 16, 2021. The pilot reported no medical conditions and the use of no medications.
