# NTSB MIA98LA003: Cessna 182G, N3434S, Jackson, MS, October 3, 1997 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: October 3, 1997, 09:42 local (14:42 UTC) - Place: Jackson, MS - Coordinates: 32.259895, -90.089286 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.2599&lon=-90.0893&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 2 uninjured - Status: Completed, report July 23, 1999 - Report: Approved by Office Director - NTSB case key (mKey): 38414 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA98LA003 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38414/pdf - Page: https://openairdocs.org/ntsb/MIA98LA003 ## Probable cause A partial loss of engine power during the initial climb due to a blockage of the induction system by a piece of gasket material. ## Analysis The pilot stated that before departure he performed an engine run-up with no discrepancies noted. After takeoff from the 8,501 foot runway, the engine experienced a partial loss of power. He verified the positions of the propeller, fuel selector, and mixture controls and also looked at the rpm and manifold pressure gauges. The engine power was restored to maintain level flight and with insufficient runway remaining, he elected to maneuver to return for landing. The engine again experienced a partial loss of power and while descending for a forced landing on a road, the airplane collided with the top of a chain link fence, then the ground and a road sign pole before coming to rest upright. Examination of the airplane by an FAA airworthiness inspector revealed that two ignition leads were inoperative and two cylinders had low compression. Additionally, gasket material was found lodged between the carburetor throat and the upper portion of the venturi. The gasket material was the exact shape of a piece missing between the carburetor mount flange and the airbox assembly. ## Factual narrative On October 3, 1997, about 0942 central daylight time, a Cessna 182G, N3434S, registered to a private individual, was substantially damaged during a forced landing shortly after takeoff from the Jackson International Airport, Jackson, Mississippi. Visual meteorological conditions prevailed at the time and a VFR flight plan was filed for the 14 CFR part 91 personal flight. The private-rated pilot sustained minor injuries and two passengers were not injured. The flight was originating at the time of the accident. The pilot stated that he performed an engine run-up before departure with no discrepancies noted. He then initiated a takeoff from the 8,501-foot-long runway and during the initial climb at 100 feet above ground level, a sudden momentary reduction in engine power occurred. He then checked the manifold pressure, engine rpm gauge, mixture, fuel selector, and propeller lever positions for proper positions. Engine power sufficient to maintain level flight was restored and with insufficient runway remaining, he maneuvered the airplane to return for landing. The engine again experienced a partial loss of power and he maneuvered to avoid cars and obstructions then while descending for a forced landing on a road, the airplane collided with the top of a chain link fence then the ground and a sign pole before coming to rest upright. Examination of the airplane by an FAA airworthiness inspector revealed sufficient fuel to sustain engine operation with no fuel contaminants noted in the wing fuel tanks or in the gascolator. Two of the ignition leads were determined to be inoperative and low compression was noted in two of the cylinders. Additionally, gasket material was found lodged between the throat of the carburetor and the upper portion of the venturi. The gasket material was the exact shape of a section of gasket material that was missing between the carburetor air box and the mount flange of the carburetor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, takeoff - initial climb - induction air control/system - blocked(partial) (cause) - Forced landing, emergency descent/landing - In flight collision with object, emergency landing - object - fence ## Aircraft - Registration: [N3434S](https://openairdocs.org/aircraft/N3434S), registered now, S/N 18255834, built 1964 (OpenAirDocs) - Reported make and model: Cessna 182G - Registry model: [Cessna 182G](https://openairdocs.org/model/cessna-182g) (registry code 2072716) (OpenAirDocs) - Registry engine: [Continental O-470R](https://openairdocs.org/engine/continental-o-470r) (registry code 17071, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18255834 - Airframe hours: 3410 - Engines: Continental O-470R 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Edward W.
