# NTSB LAX99LA173: Cessna 152, N48845, Chandler, AZ, May 8, 1999 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: May 7, 1999, 22:19 local (May 8, 1999, 05:19 UTC) - Place: Chandler, AZ - Coordinates: 33.320415, -111.820518 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=33.3204&lon=-111.8205&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report November 22, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 46268 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX99LA173 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/46268/pdf - Page: https://openairdocs.org/ntsb/LAX99LA173 ## Probable cause The pilot's improper use of the carburetor heat and throttle control (rapid movement), which induced an overly rich condition and a loss of power. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, go-around (vfr) - throttle/power control - improper use of, pilot in command (cause) - carburetor heat - improper use of, pilot in command (cause) - fuel system,carburetor - other - Forced landing, emergency descent/landing - In flight collision with object, emergency landing - object - tree(s) - object - utility pole - terrain condition - berm ## Analysis During a go-around about 100 feet agl, the pilot applied full power and pushed in the carburetor heat and the engine quit completely, with no coughing or sputtering. The pilot reported that he headed for a field about 15 degrees off the runway heading. The aircraft touched down in the field and impacted a berm, a tree, and finally a light post. During recovery operations as the airplane was being trailered to the airport, a steady stream of fuel flowed out of the bottom fuel sump. The aircraft was later moved to another location where approximately 1 gallon of fuel was found in the tanks. An examination of the engine was conducted following recovery of the aircraft. No mechanical discrepancies were found with the engine or fuel system components. Dark sooty deposits were found in the carburetor throat. The carburetor does not have an accelerator pump. ## Factual narrative On May 7, 1999, at 2219 hours mountain standard time, a Cessna 152, N48845, lost engine power and collided with obstacles and terrain approximately 1/4 mile from the Stellar Airpark in Chandler, Arizona. The aircraft, operated by South Bay Aviation, Torrance, California, and rented by the pilot for the personal cross-country flight, sustained substantial damage. The private pilot and passenger suffered minor injuries. The flight, conducted under the provisions of 14 CFR Part 91 of the Federal Aviation Regulations, originated in Torrance about 1840, and was en route to the Stellar Airpark. Night visual meteorological conditions prevailed. A visual flight rules (VFR) flight plan was filed and activated, and, VFR flight following was being provided to the pilot during the course of the flight. The pilot reported that he topped off both fuel tanks before takeoff and checked the tanks visually to verify that they were full. He opened a VFR flight plan approximately 10 minutes into the flight. His flight plan information indicated that he estimated the trip to take about 3 hours 15 minutes. The pilot reported that he flew at 7,500 feet agl and leaned the mixture for best economy fuel burn. The pilot reported that he had trouble locating the airport and received radar vectors from Phoenix TRACON. He stated that the vectors set him up for left traffic to runway 35. He first flew over the airport to get a feel for the layout of the runway. The pilot reported that he remained in left traffic, announced his landing intentions over the radio, and setup for a normal approach. He checked his fuel gauges and noted that both sides reflected 1/4 tank, which he estimated to be about 3 gallons in each side. About 200 feet agl, he noted that the runway appeared shorter than what was depicted on the chart or noted in the airport facility directory. The pilot performed a go-around and came back to setup for a short approach. He heard someone else on the radio frequency announcing that he was taxiing onto the active runway. The pilot couldn't see the aircraft, but decided to go around. He reported that he applied full power, pushed the carburetor heat in, and established a positive rate of climb. About 100 feet agl, the engine quit completely, with no coughing or sputtering. The pilot wasn't able to restart the engine and headed for a field about 15 degrees off the runway heading. The aircraft touched down in the field, impacted a berm, and became airborne again. The pilot stated that the airplane hit a tree with the right wing about 20 feet agl, then hit a light post with the left wing about 8 feet agl. The aircraft rotated forward and impacted the street in a nose down attitude. The aircraft nosed over and the tail hit a tree. The airplane came to rest inverted, with its tail resting against the tree. The Airport/Facility Directory information for Stellar Airpark indicates that the lighting for runway 35 is "non-standard." The runway is 4,004 feet long and only the last 2,000 feet are lighted; there are no threshold lights. A witness stated that because of the nonstandard lighting, approaches to Stellar Airpark are normally made from the north. The pilot reported that he assisted with the aircraft recovery following the accident. He noted that while the airplane was being trailered to the airport, a steady stream of fuel flowed out of the bottom fuel sump. The aircraft was later moved to another location. The aircraft recoverer reported that he removed approximately 1 gallon of fuel from the aircraft after it arrived at his facility. An examination of the engine was conducted following recovery of the aircraft. External examination of the engine revealed that the oil pan was cracked and oil was leaking out. No oil remained in the tank. The crankshaft was also cracked. The propeller was rotated through. The spark plugs were removed and it was noted that they exhibited wear and color patterns consistent with a short service time and correct heat range according to the Champion Aviation Check-A-Plug chart. Both magnetos produced sparks when rotated. Crankshaft rotation produced thumb compression in each cylinder, and, accessory gear and valve train continuity was established. Visual inspection of the induction system revealed a dark black discoloration. The carburetor was removed and disassembled and was noted to exhibit dark sooty deposits in the throat. The carburetor bowl contained approximately 1 inch of fuel, which appeared to be absent of debris or water. The carburetor was not equipped with an accelerator pump. ## Aircraft - Registration: [N48845](https://openairdocs.org/deregistered/N48845-1999-12-15), registration cancelled 1999-12-15, S/N 15280999 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Category: Airplane - Serial number: 15280999 - Airframe hours: 6008 - Engines: Lycoming O-235-L2C 110 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: South Bay Aviation - Registered owner: Jerome Chandler - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: Annual, April 1, 1999, 32 hours before - Departed: TOA, TORRANCE, CA - Destination: P19 - Flight plan: VFR - Airport: P19, Stellar Airpark, runway 35, 4,004 × 55 ft, asphalt ## Flight crew As NTSB recorded them.
