NTSB Factual Report

HISTORY OF FLIGHT

On June 16, 1998, about 0514 hours Pacific daylight time, a Mooney M20R, N130RB, operated under 14 CFR Part 91 by the pilot was destroyed during collision with a residence at Van Nuys, California. The pilot and passenger both received fatal injuries. Instrument meteorological conditions prevailed and no flight plan was filed. According to airport police at 0512, the aircraft departed from runway 16R without radio transmission.

The air traffic control tower was closed at the time of the departure. Radar data obtained from the airport noise abatement program indicated a right climbing turn to about 2,200 feet msl, followed by a rapid descent into a residential area. The Federal Aviation Administration (FAA) Burbank Approach radar recording system was down for maintenance at the time of the accident.

According to a family member, the pilot was en route to a Minneapolis, Minnesota, for an appointment at the Mayo Clinic.

PILOT INFORMATION

The private pilot was rated for airplane single engine land in visual flight conditions. The pilot was not instrument rated and had no known instrument flight training. The pilot's flight logbook was not recovered. At the pilot's last third-class flight physical dated April 4, 1997, he reported a total flight time of 4,100 hours. The pilot had recently purchased the accident aircraft and attended Flight Safety International to meet the VFR requirements of his insurance company.

On January 21, 1998, the pilot completed a Mooney Pilot Initial Training Program. The training started on January 19, 1998, and consisted of ground school and briefing on the Mooney aircraft and systems, with 5.5 hours of VFR flight maneuvers. The pilot's file folder listed 4,000 total flight hours with 3,900 as pilot-in-command and 3,600 in a Mooney.

AIRCRAFT INFORMATION

According to the aircraft logbook, the new aircraft certification occurred on April 30, 1997. The same log entry states that the next annual inspection was due April 30, 1998. Delivery of the aircraft to the owner/pilot occurred on May 20, 1997. The first and last logbook entry, other than the factory entries, occurred on April 29, 1998, at 39.6 total flight hours. That entry was for the installation of extended range fuel tanks. Weight and balance figures were computed after the fuel tank installation. The new useful load limit for fuel, baggage, pilot, and passengers is 1,020 pounds.

FAA certificated aircraft operating under 14 CFR Part 91 (General Operating and Flight Rules) are required to have an annual inspection every 12 calendar months.

The auxiliary fuel tank installation adds an additional 29 gallons of usable fuel to the existing 89 gallons for a total of 118 gallons. According to the installer, an additional 12 gallons can be added using the proper refueling technique and allowing the fuel to balance or transfer. The fuel load at the time of departure could not be determined.

During the auxiliary fuel tank installation and according to the airframe logbook, the proprietor of the company noted that the aircraft was out of annual inspection/license. He stated that he informed the owner pilot of this condition. The owner/pilot told him that he was going to have Dugosh Aircraft Service Company, Inc., of Kerrville, Texas, perform the annual inspection. A copy of the proprietor's statement is attached.

Dugosh Aircraft Service Company, Inc. was contacted regarding an appointment for an annual inspection. According to Dugosh, the inspection was scheduled by the owner/pilot for October 13, 1998, after the annual Mooney owner/pilots convention (MAPA) scheduled for October 8, 9, and 10, 1998. A copy of the Dugosh representative's statement is attached.

METEOROLOGICAL CONDITIONS

Aviation weather information "AIRMET SIERRA" was valid for the time of the accident for California and coastal waters. The Airmet reported in part: occasional ceilings below 1,000 feet, and visibility below 3 miles and mist. The cloud tops were reported about 3,000 feet msl.

At 0509, the Van Nuys Automated Surface Observation System (ASOS) was reporting: wind 130 degrees at 6 knots; visibility 3 miles in mist; sky condition 900 feet overcast; temperature 61 degrees Fahrenheit; dew point 57 degrees Fahrenheit; and altimeter 29.82 inHg.

About 0600, an airport witness provided a weather observation of sky condition approximately 400 overcast and visibility was about 2.5 miles.

A Safety Board meteorological factual report is attached. There was no Federal Aviation Administration (FAA) record of a preflight weather briefing.

AIRPORT INFORMATION

The Van Nuys Airport traffic is controlled by an FAA Air Traffic Control Tower operating between 0600 and 2245. During the tower operation the airspace is class "D" controlled. During the hours of closure the airspace is class "G" uncontrolled, up to but not including 3,000 feet agl. Above that, 3,000 to 4,800 msl, it becomes the Burbank class "C" airspace, all under the Los Angeles mode "C" veil.

WRECKAGE AND IMPACT INFORMATION

The wreckage was examined on scene inside a two-story home in a residential area of Van Nuys. It was located at ground level below the floor of a dining room area. The aircraft had penetrated the roof and two floors.

On July 7, 1998, the Safety Board conducted a detailed examination of the aircraft and engine. During the examination it was determined that the landing gear and the flaps were in the retracted position at the time of the accident.

A postaccident fire consumed some of the aircraft and home structure. Radio, autopilot components, and instruments were fire and impact damaged. Control continuity was established where possible. The fuel selector was on the right fuel tank. Altimeter barometric pressure was set at 29.92 inHg. The horizontal situation indicator (King KCS-55A HSI) heading bug was indicating 056 degrees; Omni bearing selector and heading were indicating 350 degrees. The instrument pressure was indicating 6 inches. There was no gyro rotor scoring information available.

Baggage items located inside the aircraft were examined. Clothes, shoes, food, fruit, candy, tools, aircraft battery, oil filter, several quarts of oil, two medical oxygen bottles (DOT 3AL2015M44824M4002), the installed aircraft oxygen bottle, a breathing machine, water, books, and maps were among the items. The weight of the baggage was estimated to be in excess of 100 pounds.

A measurement was taken from the safety hinge of the horizontal stabilizer and was given to the Mooney Aircraft Company Engineering Department. They reported that the measurement equated to a -4.05 degree (leading edge down) angle of attack of the horizontal stabilizer.

MEDICAL AND PATHOLOGICAL INFORMATION

On June 17, 1998, the Los Angeles County Medical Examiner performed an autopsy on the pilot. The cause of death was listed as multiple blunt force trauma. During the course of the autopsy the FAA Civil Aeromedical Institute in Oklahoma City, Oklahoma City obtained samples for toxicological analysis. The results of the analysis were negative for carbon monoxide, cyanide, volatiles, and drugs.

According to the medical examiner's autopsy report, in his opinion: "Because the decedent's injuries are of a type expected to cause instantaneous death, I cannot tell whether or not he was alive at the time of the impact. The body hemorrhages of injury are absolutely minimal and far out of proportion to the degree of skeletal and organ disruption. The complete absence of intra-cranial hemorrhage is noteworthy in this regard. The decedent had an enlarged heart and had experienced recent symptoms that could have been cardiac. Thus, a sudden cardiac death in flight is a possibility that would be consistent with all the findings. However, it cannot be diagnosed from the autopsy findings."

The pilot was known to have several medical conditions that were documented in the Mayo Clinic correspondence recovered by the coroner in the wreckage. Medical conditions noted were: elevated blood glucose, abdominal (LUQ) pain, shortness of breath, prostate cancer, enlarged heart, arrthymia problems, spots on the liver, and goiter issues.

According to a family member, the breathing machine was for sleep apnea.

TESTS AND RESEARCH INFORMATION

The Teledyne Continental IO-550-G engine was shipped to the Continental Motors, Mobile, Alabama. The engine was disassembled and examined under the supervision of an FAA representative. According to the representative there were no conditions or failures noted that would have been considered causal in the accident.

ADDITIONAL INFORMATION

On March 11, 1999, the wreckage was released to the insurance company representative.

Attempts were made to obtain refueling information from Van Nuys Airport and a family member. The aircraft was not recorded in the daily refueling log; however, information obtained from the service was that the pilot might have refueled at the self-serve island. No fueling records were recovered.

The pilot was reported to have an alias name of Jake Miller. Fuel records were also checked under that name.

A friend of the pilot was interviewed on public television. He reported that the pilot would occasionally depart early in the morning before the FAA tower opened in marginal weather.

NTSB Probable Cause

the non-instrument rated pilot's intentional VFR flight into instrument meteorological conditions. Factors were the low ceiling, drizzle, and fog.
