# NTSB CHI97LA223: Cessna 188B, N4926R, Adams, NE, July 23, 1997 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 23, 1997, 11:15 local (16:15 UTC) - Place: Adams, NE - Coordinates: 40.449623, -96.510429 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.4496&lon=-96.5104&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report May 29, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 10639 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI97LA223 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/10639/pdf - Page: https://openairdocs.org/ntsb/CHI97LA223 ## Probable cause inadequate maintenance/annual inspection, and subsequent exhaustion of hydraulic (brake) fluid, which resulted in loss of braking action (right brake) and impact with a tree. The proximity of tree(s) was a related factor. ## 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 - maintenance,annual inspection - inadequate, other maintenance personnel (cause) - fluid,hydraulic - exhaustion (cause) - landing gear,normal brake system - inoperative (cause) - On ground/water collision with object, landing - roll - object - tree(s) (contributing factor) ## Analysis During a landing, the airplane exited the runway and impacted trees. The pilot said that the right brake failed to work. A postaccident inspection revealed the right brake master cylinder was devoid of any hydraulic fluid. There was no indication of a leak from the brake system. The airplane had been flown about 32 hours since the last annual inspection. ## Factual narrative On July 23, 1997, at 1115 central daylight time, a Cessna 188B, N4926R, sustained substantial damage when directional control was lost while landing on a private strip, three miles east of Adams, Nebraska. The airplane exited the runway and impacted trees. The pilot reported no injuries. The right brake master cylinder was found to be empty on examination. The 14 CFR Part 137 flight was operating in visual meteorological conditions. No flight plan was on file for the local flight. The flight departed for an aerial application at 0900. The pilot said that on rollout after landing, the right brake did not work and the airplane exited the runway and ran into trees. He said that on previous flights the brakes had operated normally. He said that he had not had to service the brakes and did not know of any leaks which could be attributed to the brake system. A post accident examination of the airplane found the right brake master cylinder empty of hydraulic fluid. The last inspection of the airplane was an annual inspection on June 1, 1997. The airplane had operated 32 hours since the inspection. There was no indication of a preexisting hydraulic fluid leak in the brake system. ## Aircraft - Registration: [N4926R](https://openairdocs.org/deregistered/N4926R-2000-07-17), registration cancelled 2000-07-17, S/N 18802443T (OpenAirDocs) - Reported make and model: Cessna 188B - Registry model: [Cessna A188B](https://openairdocs.org/model/cessna-a188b) (registry code 2073005) (OpenAirDocs) - Category: Airplane - Serial number: 18802443T - Airframe hours: 4384 - Engines: Continental IO-520-D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: James C.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
