# NTSB SEA00LA195: Boeing E75, N8528N, Salem, OR, September 30, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 30, 2000, 13:35 local (20:35 UTC) - Place: Salem, OR - Coordinates: 44.900127, -123.059539 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=44.9001&lon=-123.0595&mi=10 - Phase of flight: [Taxi](https://openairdocs.org/ntsb-phases/250) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 6, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 50392 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA195 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50392/pdf - Page: https://openairdocs.org/ntsb/SEA00LA195 ## Probable cause The pilot's failure to maintain aircraft control upon experiencing a loss of normal braking effectiveness. Factors included a partial failure of the brake system, a tailwind, and a parked aircraft. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, taxi - to takeoff - landing gear,normal brake system - failure,partial (contributing factor) - aircraft control - not maintained, pilot in command (cause) - weather condition - tailwind (contributing factor) - On ground/water collision with object, taxi - to takeoff - object - aircraft parked/standing (contributing factor) ## Analysis The pilot reported that 45 minutes before the accident, he had washed the aircraft's engine with water and engine cleaner and that he intended to dry the engine by flying once around the local traffic pattern. The pilot stated that 'as [the] taxi progressed [the] brakes became progressively non functional and [the] aircraft began a slow turn to the left aided by a strong tailwind.' The pilot reported that attempts to stop the aircraft and to maintain directional control by braking were ineffective 'in spite of VERY strong pedal pressure' (emphasis in original). The pilot stated that power was at idle when the continuing turn ended in a collision with a parked and unoccupied Cessna airplane at about 4 MPH. The pilot stated that the aircraft's brakes became wet during taxi. ## Factual narrative On September 30, 2000, a Boeing E75, N8528N, was substantially damaged when it taxied into a parked and unoccupied Cessna aircraft, N738DT, while taxiing for takeoff at McNary Field, Salem, Oregon. The private pilot-in-command, who owned the aircraft and was its sole occupant, was not injured in the accident. Visual meteorological conditions prevailed and no flight plan had been filed for the intended 14 CFR 91 local personal flight. The pilot reported that 45 minutes before the accident, he had washed the aircraft's engine with water and engine cleaner and that he intended to dry the engine by flying once around the local traffic pattern. The pilot stated that "as [the] taxi progressed [the] brakes became progressively non functional and [the] aircraft began a slow turn to the left aided by a strong tailwind." The pilot reported that attempts to stop the aircraft and to maintain directional control by braking were ineffective "in spite of VERY strong pedal pressure" (emphasis in original). The pilot stated that power was at idle when the continuing turn ended in a collision with the parked Cessna at about 4 MPH. The pilot stated that the aircraft's brakes became wet during taxi. Documentation furnished by the pilot indicated that the aircraft's last annual inspection signoff was on March 15, 2000. ## Aircraft - Registration: [N8528N](https://openairdocs.org/aircraft/N8528N), registered now, S/N 75-5045, built 1942 (OpenAirDocs) - Reported make and model: Boeing E75 - Registry model: [Boeing E75](https://openairdocs.org/model/boeing-e75) (registry code 1380120) (OpenAirDocs) - Registry engine: [Lycoming R680](https://openairdocs.org/engine/lycoming-r680) (registry code 41540, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-5045 - Engines: Lycoming R-680 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: John M.

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.
