# NTSB SEA94LA013: Cessna 172N, N7367E, Renton, WA, October 9, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 9, 1993, 12:39 local (19:39 UTC) - Place: Renton, WA - Coordinates: 47.460083, -122.209579 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=47.4601&lon=-122.2096&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report September 13, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 41839 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA94LA013 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/41839/pdf - Page: https://openairdocs.org/ntsb/SEA94LA013 ## Probable cause THE STUDENT PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING LANDING. THE CROSSWIND WAS A 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 - weather condition - crosswind (contributing factor) - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, landing - object - airport facility ## Analysis THE STUDENT PILOT WAS EXECUTING AN APPROACH TO A LANDING ON RUNWAY 33 AT THE RENTON MUNICIPAL AIRPORT. WINDS WERE REPORTED AS 270 DEGREES MAGNETIC AT 10 KNOTS. APPROACHING THE THRESHOLD, THE AIRCRAFT SUDDENLY DRIFTED RIGHT OF CENTERLINE AND THEN PROGRESSED OFF THE RUNWAY PAVEMENT. THE PILOT WAS ABLE TO REGAIN CONTROL OF THE AIRCRAFT SO AS TO PREVENT A COLLISION WITH AIRCRAFT PARKED IN HIS GROUND PATH, BUT UNABLE TO PREVENT IMPACTING AN NDB ANTENNA DURING THE RECOVERY. ## Factual narrative On October 9, 1993, at 1239 hours Pacific daylight time (PDT), a Cessna 172N, N7367E, registered to and operated by the Boeing Employees Flying Association, Inc., and being flown by Edward J. Cierebiej, a certificated student pilot, collided with the non directional beacon (NDB) antenna at the Renton Municipal Airport, after a loss of directional control during landing. The aircraft sustained substantial damage and the pilot was uninjured. Visual meteorological conditions existed and the wind at the airport at the time of the accident was recorded as 270 degrees magnetic at 10 knots. The flight, which was an instructional solo, was to have been operated in accordance with the requirements set forth in 14CFR91 and departed from the Renton airport at approximately 1130 hours. The pilot reported that once crossing over the blast fence (short of the threshold to runway 33) and "In ground effect, the aircraft, again, seemed hard to control." He stated that he encountered a sudden "jerk to the left, presumably from a gust of wind" and then the aircraft "was suddenly to the right of centerline." The pilot reported that the aircraft was "off the paved runway" and "Since I got no response from the rudder, I did not want to power-up for a go-around, with the possibility of not having control." The pilot reported that he regained enough control to prevent the aircraft from striking parked aircraft in his ground path, but was unable to avoid the NDB antenna which the aircraft impacted with its outboard leading edge right wing. A tower controller who witnessed the accident reported seeing the aircraft veer to the right while landing on runway 33 during the second attempted landing. The controller reported that the pilot appeared to regain control but the aircraft collided with the NDB antenna shortly thereafter. The controller also reported that he made several announcements of wind speed and direction to aircraft in the landing pattern immediately preceding the accident. ## Aircraft - Registration: [N7367E](https://openairdocs.org/aircraft/N7367E), registered now, S/N 17272096 (OpenAirDocs) - Reported make and model: CESSNA 172N - Registry model: [Cessna 172N](https://openairdocs.org/model/cessna-172n) (registry code 2072434) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17272096 - Engines: LYCOMING O-320-H2AD 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Boeing Employees Flying Assn - Registered owner: Boeing Employees Flying Assn - Airworthiness certificate: Standard, Normal - Departed: RNT - Destination: RNT - Airport: RNT, Renton Municipal, runway 33, 5,379 × 200 ft, asphalt ## Flight crew As NTSB recorded them.

Drifted off runway alignment on crosswind landing. Ran off runway. Avoided parked aircraft but struck NDB antenna. From the NTSB's public API. 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.
