# NTSB SEA02LA160: Piper PA-18, N1277A, Newberg, OR, August 19, 2002 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 19, 2002, 09:35 local (16:35 UTC) - Place: Newberg, OR - Coordinates: 45.323612, -123.054443 - Nearby events: https://openairdocs.org/map.md?lat=45.3236&lon=-123.0544&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report April 8, 2003 - Report: Approved by Office Director - Parties: FAA Flight Standards District Office - NTSB case key (mKey): 55517 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA02LA160 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/55517/pdf - Page: https://openairdocs.org/ntsb/SEA02LA160 ## Probable cause A warped right brake disc resulting in a veer to the right during the landing roll, and the aircraft's subsequent collision with a fence. A contributing factor was the fence. ## 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 - landing gear,normal brake system - binding(mechanical) (cause) - On ground/water collision with object, landing - roll - object - fence (contributing factor) ## Analysis The pilot of the tail-wheel equipped Piper PA-18 was executing a landing on runway 25 under calm wind conditions when the aircraft began to veer to the right. The aircraft departed the runway and then impacted a fence. Both the pilot and the accompanying instructor reported that the application of left rudder was unsuccessful in controlling the aircraft's direction. Subsequent examination of the aircraft's brake system revealed that the right main gear brake disc was warped. ## Factual narrative On August 19, 2002, approximately 0935 Pacific daylight time, a Piper PA-18 airplane, N1277A, registered to and being flown by a private pilot who had recently bought the airplane, ran off the right side of runway 25 during landing at Chehalem Airpark (17S), Newberg, Oregon, and collided with a fence. The airplane was substantially damaged. At the time, the pilot, who was qualified and current under 14 CFR 61 to act as pilot-in-command of the airplane, had a certificated flight instructor aboard in order to fulfill an insurance policy provision requiring him to accumulate 10 hours in the aircraft prior to flying without an instructor. Neither pilot was injured. Visual meteorological conditions, with calm winds, were reported at McMinnville, Oregon, at 0953, and no flight plan had been filed for the 14 CFR 91 instructional flight, which departed Stark's Twin Oaks Airpark (7S3), Hillsboro, Oregon, about 0915. Both pilots reported that during the landing under calm wind conditions, the aircraft began to pull to the right, and that application of left rudder was unsuccessful in controlling the aircraft's direction. Subsequent to the accident the aircraft's brake system was examined. The examination revealed that the right main gear brake disc was warped (refer to attached NTSB Forms 6120.1). ## Aircraft - Registration: [N1277A](https://openairdocs.org/aircraft/N1277A), registered now, S/N 18-1072, built 1951 (OpenAirDocs) - Reported make and model: Piper PA-18 - Registry model: [Piper PA-18](https://openairdocs.org/model/piper-pa-18) (registry code 7101802) (OpenAirDocs) - Registry engine: [Lycoming 0-290 series](https://openairdocs.org/engine/lycoming-0-290-series) (registry code 41506, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 18-1072 - Engines: Lycoming O-320-A2B 150 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Robert W.
