# NTSB CHI94LA127: Beech 35, N9597R, Anderson, IN, April 4, 1994 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 4, 1994, 16:15 local (21:15 UTC) - Place: Anderson, IN - Coordinates: 40.150886, -85.620819 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.1509&lon=-85.6208&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report March 13, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9502 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI94LA127 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9502/pdf - Page: https://openairdocs.org/ntsb/CHI94LA127 ## Probable cause the pilot's failure to maintain directional control during the landing roll. A factor related to the accident was the rough terrain encountered following the loss of control. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command (cause) - fuel system,vent - blocked(partial) - On ground/water encounter with terrain/water, landing - roll - terrain condition - rough/uneven (contributing factor) - Nose gear collapsed, landing - roll - landing gear,nose gear - overload ## Analysis THE PILOT WAS UNABLE TO DRAIN FUEL FROM THE RIGHT TIP TANK DURING THE FLIGHT DUE TO A FUEL SYSTEM VENTING PROBLEM. HE STATED THE AIRPLANE BECAME VERY HARD TO CONTROL DURING THE TRAFFIC PATTERN. DURING THE LANDING ROLL, THE AIRPLANE VEERED OFF THE RIGHT SIDE OF THE RUNWAY INTO ROUGH TERRAIN WHERE THE NOSE GEAR COLLAPSED. ## Factual narrative On April 4, 1994, at 1615 eastern standard time, a Beech BE-35, N9597R, registered to Robert Trindel, experienced a nose gear collapse following a loss of directional control while landing on runway 18 at the Anderson Municipal Airport, Anderson, Indiana, while on a personal flight. Visual meteorological conditions prevailed and no flight plan was filed. The airplane was substantially damaged and the pilot was not injured. The flight originated from Leesburg, Florida, on April 4, 1994, at 1200 edt. The pilot stated he periodically switched fuel tanks during the flight to establish an even fuel burn. However, he stated he was unable to drain the 20 gallons of fuel which was in the right tip tank. The pilot reported that he continued on to his destination of Anderson, Indiana. The pilot was cleared for a right base leg for runway 18. The pilot stated he switched to the left tank while entering the pattern and the airplane became "extremely hard to control." The airplane touched down on runway 18 and during the landing roll it traveled off the right side of the runway, into rough terrain where the nose gear collapsed. Post accident inspection revealed the fuel system was not venting properly which resulted in the lack of ability to drain fuel from the right tip tank. Local winds reported 30 minutes prior to the accident were from 200 degrees at 12 knots. ## Aircraft - Registration: [N9597R](https://openairdocs.org/aircraft/N9597R), registered now, S/N D-6191, built 1959 (OpenAirDocs) - Reported make and model: BEECH 35 - Registry model: [Beech M35](https://openairdocs.org/model/beech-m35) (registry code 1151526) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: D6191 - Airframe hours: 6040 - Engines: CONTINENTAL IO-470-C 250 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Robert Trindel - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 24, 1994 - Departed: LEE, LEESBURG, FL - Flight plan: VFR - Airport: AID, Anderson Muni, runway 18, 3,399 × 75 ft, concrete ## Flight crew As NTSB recorded them.
