NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On April 18, 2016, about 1805 Pacific daylight time, a Cessna 182A, N9909B, was substantially damaged during a forced landing following a loss of engine power near Selma, California. The airplane was registered to HBC Aero LLC, Rancho, Murieta, California, and operated by the student pilot. The student pilot and the Certified Flight Instructor (CFI) sustained minor injuries. Visual meteorological conditions prevailed and no flight plan was filed for the instructional flight. The cross-country flight originated from Mc Clellan-Palomar Airport, Carlsbad, California, about 1600, with an intended destination of Madera, California.

In a written statement to and a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), the flight instructor (FI) reported that following an uneventful flight from Rancho Murieta to Hesperia, California, they flew to Apple Valley, California, to refuel. The FI stated that they topped the airplane off with 56.08 gallons of fuel, and flew to Carlsbad, which was about a 1-hour flight, where they dropped two people off prior to departing to return to Rancho Murieta.

During the flight, the FI and student pilot decided instead of their original intended fuel stop at Fresno, California, they would refuel in Madera. The FI further stated that during a descent from 6,500 feet to 4,500 feet mean sea level (msl), the engine lost power. The FI and student pilot received vectors from air traffic control to the nearest airport. Despite multiple attempts, the FI was unable to restart the engine, and realized they would not be able to make it to the Selma Airport, Selma, California. Subsequently, the FI initiated a forced landing to an open field, and during the landing roll, the airplane nosed over. The FI reported that during the descent, carburetor heat was not used.

Examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed that the airplane came to rest in a field, which contained a mix of sand and dirt. The right wing and fuselage were structurally damaged. The airplane was recovered to a secure location for further examination.

Examination of the recovered airframe and engine was conducted on June 15, 2016, at the facilities of Plain Parts, Pleasant Grove, California, by representatives of Cessna Aircraft and Continental Motors Inc. under the supervision of the NTSB IIC.

Both wings and the empennage were separated from the airplane to facilitate recovery of the wreckage. Personnel from the recovery company reported that there was less than 2 quarts of fuel in either fuel tank. Both the left and right fuel caps remained attached and secure. The airframe was intact and undamaged. The nose wheel landing gear was separated. Impact damage to the airframe air filter and air box was observed. When an alternate fuel sources was plumed to the right wing fuel inlet port, fuel was observed leaking out of the airframe fuel strainer. The fuel strainer valve was found stuck in the open position along with an abundance of sand like debris. The debris was cleaned away, and the fuel strainer valve closed normally.

All accessories remained attached, the ignition harness was intact, and the right side engine mounts were fractured. The left side exhaust was damaged. The crankshaft was rotated by hand, and thumb compression was obtained on all cylinders. In addition, when the crankshaft was rotated, spark was observed on all ignition leads. Due to propeller damage, a test club propeller was installed on the engine in order to facilitate an engine run.

An external power supply was connected to the airplane's electrical system, and the engine was started. Initially, the engine ran for about 80 seconds before losing power. Multiple attempts were made to start the engine again, however, the engine would only start when primed, and would not continue running once the initial primer fuel was exhausted. The carburetor was then removed from the engine and disassembled. A small amount of sand like debris was cleared from the Mixture Metering Sleeve using light air pressure. No other anomalies were noted with the carburetor. The carburetor was reassembled and reinstalled on the engine. The engine started, and ran continuously at various power settings until the mixture control was moved to the idle cutoff position. The sources of the debris located within the carburetor mixture metering sleeve was undetermined.

Review of the Cessna 182 Pilots Operating Handbook (POH), 182 Cruise and Range Performance Chart, depending on rpm, manifold pressure, and mixture settings, fuel burn rates vary between 9.7 and 14.5 gallons per hour. The airplane was equipped with two wing fuel tanks, which have a capacity of 32.5 gallons of fuel per tank. The POH states that the left and right fuel tank have a usable fuel of 27.5 gallons per tank in all flight conditions along with an additional 3.5 gallons of fuel useable in level flight only. Each fuel tank has an unusable fuel level of 1.5 gallons.

The NTSB IIC calculated an estimated fuel burn using a fuel consumption rate of 14.5 gallons per hour, and the result was 3 hours of flight time. It was determined that the flight would have used about 43.5 gallons of fuel since the airplane was topped off with fuel.


At 1953, weather conditions recorded at the Fresno-Yosemite International Airport, located about 14 miles north of the accident site, were temperature 81 degrees Fahrenheit, dew point 43 degrees Fahrenheit. According to the Federal Aviation Administration Special Airworthiness Information Bulletin CE-09-35, entitled Carburetor Icing Prevention, the temperature and dew point were conducive to the formation of icing at glide or cruise power.

Two people were involved in a small plane crash near Fowler on Monday.

The Fresno County Sheriff’s Office said the plane, a Cessna 182A Skylane heading to Sacramento, was having engine problems and crash landed in a field near Highway 99 and Manning St., between Selma and Fowler, around 6 p.m. 

The passengers were a flight instructor and a student he was giving flying lessons to.

The department said the flight instructor suffered minor injuries. The student didn’t have any injuries.

Great there were no major injuries to the instructor or student. Also there was no fire. Possible a fuel related problem.
