Echo Bay, NV

Accident Number:


Date & Time:

06/12/2014, 2105 PDT





Aircraft Damage:


Defining Event:

Loss of control in flight


2 Fatal

Flight Conducted Under:

Part 91: General Aviation - Personal



At the end of a personal cross-country flight, the private pilot was attempting to land at night on a dark unlit runway. A witness reported that the airplane made a low pass to the east of the airport and then reversed course to presumably land on runway 24. The witness lost site of the airplane and, shortly thereafter, observed a column of smoke.

The airplane impacted terrain 50 ft lower than the runway surface, 200 yards northeast of the runway threshold, in a steep nose-down attitude. The airplane was consumed by the postimpact fire. Postaccident examination of the wreckage revealed no evidence of a mechanical malfunction or failure that would have precluded normal operation. It is likely that, while maneuvering in the dark night conditions with no ground reference or runway lighting, the pilot failed to maintain airplane control.

Toxicological testing detected methamphetamine in the pilot's tissue specimens, and the level in his liver suggested high dose use, which can cause impairment. The tests also detected tramadol, which may be sedating and is associated with an increased risk of seizure, particularly in the first days and weeks after beginning treatment or with very high doses. However, without a blood level, it could not be determined whether or not the pilot's use of tramadol or methamphetamine contributed to the accident.

Loss of control in flight (Defining event)


On June 12, 2014, about 2105 Pacific daylight time (PDT), an experimental Dittenber Express Auriga, N55GM, impacted terrain during landing at Echo Bay Airport (0L9), Overton, Nevada. The owner/pilot was operating the airplane under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The private pilot and passenger were fatally injured; the airplane was destroyed by impact forces and postcrash fire. The cross-country personal flight departed Minden, Nevada, about 1800. Visual meteorological conditions prevailed, and no flight plan had been filed.

A witness reported that the airplane made a low pass to the east of the airport and then reversed course, presumably to land at 0L9 using runway 24. The witness lost sight of the airplane as it neared the airport. A few minutes later, the witness observed a column of black smoke near the airport.

Documentation of the accident site revealed the airplane impacted terrain at a steep nose down attitude. The debris field was about 100 feet in diameter. The airplane was mostly consumed by the post-impact fire.

A review of Federal Aviation Administration (FAA) airman records revealed that the 48-year-old pilot held a private pilot certificate with ratings for airplane single-engine land and instrument airplane.

The pilot did not hold a valid medical certificate. The most recent medical held was a third-class medical certificate issued on December 16, 2011. It had the limitations that the pilot must wear corrective lenses.

No personal flight records were located for the pilot. The National Transportation Safety Board investigator-in-charge (IIC) obtained the aeronautical experience listed in this report from a review of the FAA airmen medical records on file in the Airman and Medical Records Center located in Oklahoma City, Oklahoma. The pilot reported on his medical application that he had a total time of 7,880 hours with 190 hours logged in the last six months.

The accident pilot had previously owned a Bellanca 17-30, registration number N4785V. He owned the airplane from March 22, 1995, thru August 19, 1998.

Investigators examined the wreckage at the accident scene. The first identified point of contact (FIPC) was a ground scar crater located 200 yards northeast of the runway threshold.

The impact point was on a slope at an elevation of 1,485 feet msl. The accident site was 50 feet below the runway elevation.

The wreckage was fragmented and thermally consumed by the post-impact fire.

The propeller flange was separated from the crankshaft just forward of the engine case. The crankshaft fracture surface exhibited torsional granular features on a 45-degree conical plane around its circumference.

The propeller showed S-bending, torsional twisting, bending, and scaring.

The engine exhaust system was crushed and displayed ductal deformation. The heater shroud was also crushed with ductal signatures.






The accident airplane had been in contact with Nellis Air Force Base Air Traffic Control using a registration number of N4785V, and terminated service at 2039. The radar track was observed by Terminal Radar Approach Control until about five miles west of 0L9 at 2043.


Medical And Pathological Information

According to the FAA medical case review, the pilot had reported no medications and no significant medical conditions to the FAA. He was 76 inches tall and weighed 316 lbs at his last medical exam dated December 26, 2011. At that time, he reported 7,880 total flight hours, and was issued a third-class medical certificate, limited by the need for corrective lenses. Of note, this medical certificate expired December 31, 2013.

According to the autopsy performed by the Clark County Coroner, the pilot's cause of death was multiple blunt force injuries, and the manner of death was accident. In addition to citing blunt and thermal injuries identified during the autopsy, the medical examiner noted no natural disease, but identified methamphetamine intoxication. Toxicology testing, performed at the request of the medical examiner by NMS Labs on a specimen of the pilot's liver, identified 9,500 ng/g of methamphetamine, 640 ng/g of its active metabolite amphetamine, and 280 ng/g of tramadol. Methamphetamine is a Schedule II controlled substance available by prescription, and used to treat ADHD, ADD, and narcolepsy. However, typically in much larger doses, it is also extensively used recreationally by persons who smoke, snort, or inject it. Tramadol is an opioid analgesic available as a Schedule IV controlled substance. When issued by prescription, both drugs carry warnings about driving or operating machinery while under their influence.

Toxicology testing requested by the NTSB and performed at the FAA's Bioaeronautical Research Laboratory identified methamphetamine and amphetamine in the pilot's liver and muscle as well as tramadol in liver (0.263 ug/g), kidney (0.249 ug/g), and heart tissue (0.159 ug/g).

Illicit use of methamphetamine can cause a variety of symptoms. Including intense euphoria, rapid flight of ideas, sexual stimulation, high energy, obsessive/compulsive activity, thought blending, and dilated pupils during the first few minutes, which gradually fades.

The drug may be frequently re-administered to attempt to regain the euphoria. Between dosing(regular or binging), users may experience withdrawal symptoms including dysphoria, scattered and disorganized thought, intense craving, paranoia, anxiety, irritability, hypervigilance, auditory and tactile hallucinations, and delusions. However, there is no available information linking liver levels with the stage of symptoms or level of impairment the user may experience, and no clear evidence using blood levels either.


Tests And Research

The initial reports of this accident from air traffic control identified the airplane by the registration number of N4785V that is registered to a Bellanca 17-30. A review of the registration records for N4785V revealed that the airplane was registered to an individual who resides in Florida. The owner was contacted and advised that he had sold the airplane to another person who lived in Pennsylvania.

The accident pilot was in a property dispute with his estranged wife, and was reportedly trying to keep the location of the accident airplane from her.

The airframe and engine were examined on site with no mechanical anomalies identified that would have precluded normal operation.


Additional Information

According to FAA Advisory Circular AC 20-27F, Certification and Operation of Amateur-Built Aircraft, "Amateur builders are free to develop their own designs or build from existing designs. We do not approve these designs and it would be impractical to develop design standards for the wide variety of design configurations, created by designers, kit manufacturers, and amateur builders."
