# NTSB FTW93LA260: Cessna A188B, N731UF, Manila, AR, September 19, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 19, 1993, 14:15 local (19:15 UTC) - Place: Manila, AR - Coordinates: 35.879394, -90.160728 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.8794&lon=-90.1607&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report September 26, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 18831 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW93LA260 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/18831/pdf - Page: https://openairdocs.org/ntsb/FTW93LA260 ## Probable cause PARTIAL LOSS OF ENGINE POWER DUE TO THE COLLAPSE OF AN AIR INDUCTION HOSE. ## 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 - roll/run - induction air ducting - collapsed (cause) - Forced landing, descent - emergency - In flight collision with terrain/water, descent - emergency - terrain condition - crop - In flight collision with terrain/water, descent - uncontrolled ## Analysis THE AIRPLANE DID NOT ACCELERATE, DUE TO A LOSS OF ENGINE POWER. AFTER THE PILOT DUMPED THE LOAD, THE AIRPLANE LIFTED OFF AT ABOUT 100 FEET BEFORE THE END OF THE RUNWAY BUT STILL DID NOT ACCELERATE AND SETTLED INTO THE COTTON FIELD ABOUT 300 FEET BEYOND THE END OF THE RUNWAY. THE SPRAY BOOM CAUGHT THE COTTON AND THE AIRPLANE WAS PULLED TO THE LEFT AND IT IMPACTED THE GROUND. EXAMINATION OF THE DOUBLE WALL AIR INDUCTION HOSE REVEALED THAT THE INSIDE WALL OF THE HOSE HAD SEPARATED AND BLOCKED THE AIR INTAKE. ## Factual narrative On September 19, 1993, at 1415 central daylight time, a Cessna A188B, N731UF, sustained substantial damage following a partial loss of engine power during takeoff near Manila, Arkansas. The commercial pilot was not injured. Visual meteorological conditions prevailed for the local aerial application flight. The pilot stated on the enclosed Pilot/Operator report, and during interviews conducted by a Federal Aviation Administration inspector, that the airplane was loaded with 1,600 pounds of cotton defoliate and that this was the twelfth load of the day. He further stated that this takeoff took much longer than the others. When the tail came up, he had forward visibility and he observed the remaining runway was marginal for a safe takeoff; however, "an abort was not safe because of a ditch at the end of the runway." The pilot continued the takeoff and began dumping the load at the last 200 feet of the runway. The airplane lifted off the runway at 100 feet before the end of the runway; however, it would not accelerate and began descending. At approximately 300 feet off the end of the runway, the pilot shut down the engine, as the spray booms caught in the cotton, and the airplane was pulled to the left and subsequently hit the ground. Examination of the double wall air induction hose by the operator revealed that the inside wall had separated and was blocking the air flow. ## Aircraft - Registration: [N731UF](https://openairdocs.org/aircraft/N731UF), registered now, S/N 18803160T, built 1978 (OpenAirDocs) - Reported make and model: CESSNA A188B - Registry model: [Cessna A188B](https://openairdocs.org/model/cessna-a188b) (registry code 2073005) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18803160T - Engines: LYCOMING IO-540-K 300 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Atkinson, Sidney R. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, October 23, 1992 - Airport: Private, runway 36, 2,400 × 150 ft, dirt ## Flight crew As NTSB recorded them.

Probable cause: A partial loss of engine power due to a tear in the fuel manifold diaphragm, which prevented sufficient fuel flow to the engine. From the NTSB's public API.
