NTSB Factual Report

HISTORY OF FLIGHT

On September 11, 2016, at 1813 Pacific daylight time, a Piper PA-28R-201T, N821ET, impacted an airport parking lot after takeoff from Reno/Tahoe International Airport (RNO), Reno, Nevada. The private pilot and two passengers were fatally injured, and the airplane was destroyed. The airplane was registered to RCS3 LLC and was being operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and an instrument flight rules flight plan had been filed for the personal flight, which was destined for San Carlos Airport (SQL), San Carlos, California.

The purpose of the flight was to transport the rear-seat passenger from Nevada to California, where a series of warrants had been issued for her arrest. The front-seat passenger was a California-based bail bondsman, and the pilot was his associate. Security video footage and records provided by the fixed-base operator (FBO) at RNO indicated that the airplane arrived at the FBO about 1715. A fuel order was placed 5 minutes later, and the pilot and bail bondsman then walked to the FBO's reception area. The fueling was complete by 1725, and by 1741 the pilot had returned. He removed the chocks, leant over the wings and appeared to briefly look into both fuel tank filler necks, and then boarded the airplane. About 5 minutes later the bail bondsman arrived with the arrested passenger, who was restrained by leg chains. Although her entry into the airplane was obscured from view by the fuselage, she appeared to make multiple attempts to step up into the cabin. After about 3 minutes of maneuvering, she was onboard, followed by the bail bondsman. The engine was then started at 1753, and the airplane taxied away from the ramp at 1804.

According to witnesses, the airplane began its takeoff roll from the threshold of runway 25 and, following rotation, climbed to about 200 to 300 ft above ground level (agl) before leveling off. One witness, who was a line technician for a local FBO, was positioned on the ramp just north of runway 25 and 2,000 ft from the runway threshold. He stated that the airplane initiated its rotation abeam his position and immediately began to rock around its longitudinal axis. The nose then pitched up to a high angle and remained in that attitude as the airplane continued flying above the runway while slowly climbing. He stated that the airplane's wing-rocking movements were far more exaggerated than anything he had seen at the airport before. He then watched as the airplane began to veer to the right.

About 90 seconds after issuing the takeoff clearance, the airport tower controller, concerned that the airplane was not gaining altitude, asked the pilot if he was ok. The pilot responded, "Negative we got ah, we got a problem." Ten seconds later, the tower controller cleared the pilot to land on any runway. The pilot did not make any further transmissions. Security camera footage revealed that the airplane continued over the runway and began to veer to the right of the runway centerline. The airplane then began a descending right turn and the right wing impacted a lamppost in an airport parking lot. The outboard section of the wing then separated and the airplane immediately rolled right, impacting parked vehicles and the ground. The airplane did not appear to be trailing smoke at any point during the flight, and video revealed that the landing gear was extended at the time of impact.

PERSONNEL INFORMATION

The pilot held a private pilot certificate with ratings for airplane single- and multi-engine land and instrument airplane, with a limitation of airplane multi-engine land under visual flight rules only. He held a Federal Aviation Administration (FAA) third-class medical certificate issued on January 12, 2015, with no limitations or waivers. The pilot's logbook indicated a total flight experience of about 769 hours since his first training flight in 1985 to his most recent logbook entry, dated August 23, 2016. He had accrued about 216 hours in the accident airplane since he purchased it in February 2014.

AIRCRAFT INFORMATION

The single-engine, retractable-gear airplane was registered to a corporation, of which the pilot was the sole member. The airplane was manufactured in 1977 and powered by a turbocharged, fuel-injected, Continental TSIO-360-KBcFB engine equipped with a two-blade constant-speed Hartzell propeller. The airplane was equipped with four seats and two wing-mounted fuel tanks, each of which had a capacity of 36 gallons.

The most recent annual inspection was performed on June 9, 2016. At that time, the airframe had accumulated 4,531.5 total flight hours, and the engine 1,244.21 hours since overhaul in June 2004. The most recent pitot-static, altimeter, and transponder certification was performed on March 31, 2015.

The airplane had been retrofitted with a Turboplus engine intercooler system. The flight manual supplement did not provide specific performance increase values, but rather stated, "PERFORMANCE: with the above engine and intercooler combination installed are equal to or better than the data in the FAA Flight Manual."

METEOROLOGICAL INFORMATION

After providing the initial takeoff clearance, the tower controller issued an advisory to the pilot indicating that the wind was from 260° at 12 knots gusting to 29 knots.

A special METAR for RNO was issued 25 minutes after the accident and included wind from 270° at 14 knots gusting to 23 knots; 10 miles visibility; few clouds at 11,000 ft; temperature 28°C; dew point -1°C; altimeter 29.98 inches of mercury. Based on these values, the calculated density altitude was about 6,900 ft.

According to the U.S. Naval Observatory, Astronomical Applications Department, the computed sunset occurred in San Carlos, California, at 1922, with civil twilight ending at 1948.

AIRPORT INFORMATION

RNO is located at an elevation of 4,145 ft mean sea level and is equipped with three grooved concrete runways. Runway 16R/34L is 11,001 ft long by 150 ft wide, and runway 16L/34R is 9,000 ft long by 150 ft wide. Runway 7/25 is 6,102 ft long by 150 ft wide on a gradient of 0.2%, and is bisected at its midpoint by runway 16/34.

The airport is located on the eastern flank of the Sierra Nevada mountain range. The route of flight to SQL would have been to the southwest and would have required traversing the range at an initial minimum en route altitude of 13,000 ft.

WRECKAGE AND IMPACT INFORMATION

The airplane came to rest inverted in the parking lot on a heading about 070° magnetic about 1/2 mile north of the departure end of runway 25. All major sections of the airplane were recovered at the accident site. The left wing came to rest in the flatbed of a pickup truck, and the right wing had detached and was folded aft parallel with the tailcone. The airframe sustained crush damage through to the vertical stabilizer. A car parked just west of the main wreckage exhibited a slice in its left rear quarter panel perpendicular to the airplane's heading. The dimensions of the slice matched that of a propeller blade tip. A total of fifteen vehicles were damaged during the impact.

According to first responders, the rear seat passenger remained belted into the rear left seat when they arrived at the accident site. All four seats remained attached to the cabin floor, and all seat belts remained buckled. The front two belts and the rear left belt had been cut by first responders at the accident site to recover the occupants. The rear seats were not equipped with shoulder harnesses.

The airframe and engine were examined at both the accident site and a remote storage facility following recovery. The propeller, turbocharger, and engine components were then examined at their respective manufacturing facilities under supervision of the NTSB.

The instrument panel, along with all cockpit flight controls, sustained extensive fragmentation. The fuel selector was in the left tank detent. The gascolator had been crushed, exposing the inner surface of the bowl. The bowl was free of corrosion or blockage, and the screen was free of debris.

The flight controls and their associated cables, bellcranks, chains, pushrods, and control surfaces sustained damage consistent with impact and postaccident wreckage recovery.

The stabilator trim tab, along with its associated trim screw and control arm assembly, remained attached to the stabilator. The trim jack screw in the aft cabin displayed 12 exposed screw threads on the top side. According to Piper's documentation, zero exposed threads indicated full nose down trim, 5 threads neutral, and 16 full nose-up.

Impact damage prevented an accurate assessment of the flap position.

Engine Examination

The engine sustained impact damage, which had crushed the forward inlet manifold and breached the lower portion of the oil sump, exposing the camshaft. The propeller and hub assembly were detached at the engine crankshaft forward bearing. The fuel lines, including the fuel injector lines, sustained varying degrees of damage but were intact at their respective fittings. The turbocharger assembly was partially detached from the engine. Both magnetos displayed varying degrees of external damage and were run in a magneto test stand. Both produced spark in firing order at all output leads throughout speeds ranging between 400 and 2,700 rpm.

Cylinder No. 6 exhibited crush damage to its forward face, which had displaced the intake and exhaust rockers. The engine could be rotated smoothly via the vacuum pump accessory drive, and valves from cylinder Nos. 1 through 5 exhibited similar lift heights. Drive train continuity was confirmed through to the accessories. Thumb compression was obtained on all cylinders except No. 6. The upper and lower spark plugs for cylinder Nos. 2, 3, and 4, along with the lower spark plug for cylinder No. 6, exhibited grey deposits. The remaining plugs were coated in oil. All plugs exhibited worn out-normal signatures when compared to the Champion AV-27 Check-A-Plug chart.

The oil filter was cut open for examination. The filter element was coated in brown-colored oil and was free of debris.

Turbocharger

The turbocharger assembly was largely intact. The impeller and turbine wheel did not exhibit any signs of damage, and a radial rub mark was present on the turbine housing adjacent to the inlet consistent with blade contact. With the housing removed, the compressor and turbine wheel assembly could be rotated by hand. The turbine shaft was intact, and all internal journals and bearings were intact and wet with oil.

The pressure valve was intact and exhibited no external damage beyond a scratch on the side of its housing. The unit was tested utilizing a pressure valve test bench, with the results indicating nominal performance.

Propeller

Both propeller blades remained attached to the hub and flange, which had separated from the crankshaft. The separation point at the flange exhibited a conical 45° shear lip around its entire circumference with serrated, ratchet-like tear features around most of the crown, consistent with rotation at impact. Circumferential crack marks were present on the radial surface of the shaft adjacent to the ratchet marks.

The first blade (labeled blade 'A') exhibited leading edge gouging, chordwise scratches to its front and aft surfaces, and an S-bend along its entire length. The outboard 16-inch-long section was separated, leaving a jagged tear pattern.

The second blade (labeled blade 'B') was intact, exhibited chordwise scoring on its forward side, and was bent about 15° aft 12 inches from the root. A 1-inch section of the tip had separated, leaving chordwise scoring and gouge marks at the area of separation.

No significant damage was observed to the hub, and the unit was disassembled. Per design, oil was present on the front side of the piston, with no signs of oil on or leakage to its aft side. An imprint was present on the preload plate of blade 'B', which corresponded to the bushing of the pitch change knob of blade 'A'. The position of the imprint corresponded to a blade 'A' pitch angle of 17.5°. Hartzell specifications call for a low pitch angle of 14.4 +/- 0.2°, and a high pitch angle of 29 +/-1°.

MEDICAL AND PATHOLOGICAL INFORMATION

The Washoe County Medical Examiner's Office, Reno, Nevada, performed an autopsy of the pilot; the cause of death was multiple blunt force injuries. No significant natural disease was identified.

The FAA's Bioaeronautical Sciences Research Laboratory performed toxicology testing of specimens from the pilot. The testing identified acetaminophen, hydrocodone and its active metabolite dihydrocodeine, ibuprofen, meprobamate, morphine, nordiazepam, oxazepam, temazepam, and oxymorphone in urine. In addition, 0.04 µg/ml of diazepam, 0.111 µg/ml of its active metabolite, nordiazepam, 0.021 µg/ml of hydrocodone, and 2.243 µg/ml of meprobamate were confirmed in cavity blood.

Acetaminophen is a common analgesic often marketed with the name Tylenol and used in combination with a number of opioids. Ibuprofen is an over-the-counter analgesic often marketed with the names Advil and Motrin.

Hydrocodone is a prescription opioid available as a Schedule II controlled substance, often marketed in combination with acetaminophen as Norco, Lortab, and Vicodin. Its active metabolite, dihydrocodeine, is sold as a separate prescription opioid in other countries as a controlled substance. Hydrocodone carries this warning, "Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death."

Meprobamate is a prescription anxiolytic medication available as a Schedule IV controlled substance, often marketed with the name Miltown. It carries the warning, "Patients should be warned that meprobamate may impair the mental and/or physical abilities required for performance of potentially hazardous tasks such as driving or operating machinery." It is the active metabolite of carisoprodol, a prescription medication used to treat muscle pain, also a Schedule IV controlled substance, often marketed with the name Soma. It is known to be sedating and carries the warning, "may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a motor vehicle or operating machinery. There have been post-marketing reports of motor vehicle accidents associated with the use of carisoprodol. Since the sedative effects of carisoprodol and other central nervous system depressants (e.g., alcohol, benzodiazepines, opioids, tricyclic antidepressants) may be addictive, appropriate caution should be exercised with patients who take more than one of these CNS depressants simultaneously."

Morphine is a separate opioid analgesic available as a Schedule II controlled substance in oral and IV forms; it is also the active metabolite of codeine and heroin. It carries the warning, "like all opioid analgesics, (morphine) should be used with great caution and in reduced dosage in patients who are concurrently receiving other central nervous system depressants including sedatives or hypnotics, general anesthetics, phenothiazines, other tranquilizers and alcohol because respiratory depression, hypotension and profound sedation or coma may result."

Nordiazepam is an active metabolite of diazepam, a benzodiazepine used to treat anxiety, seizures, and muscle spasms. Diazepam is available as a Schedule IV controlled substance and is often marketed with the name Valium. It carries the warning, "Patients should be advised against the simultaneous ingestion of alcohol and other CNS-depressant drugs during diazepam therapy. As is true of most CNS-acting drugs, patients receiving diazepam should be cautioned against engaging in hazardous occupations requiring complete mental alertness, such as operating machinery or driving a motor vehicle." Oxazepam and temazepam are two additional psychoactive metabolites. Each is also marketed as a separate drug, often with the names Serax and Restoril, respectively.

Oxymorphone is another opioid available by prescription as a Sc

NTSB Probable Cause

The pilot's decision to depart with the airplane loaded above its maximum gross weight and at or just beyond its aft center of gravity limitations, which resulted in a loss of control during the initial climb. Contributing to the accident was the pressure to complete the flight as planned, and the pilot's use of multiple impairing drugs, which degraded his decision-making.
