A contributing factor was the sign. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, landing - reason for occurrence undetermined (cause) - On ground/water collision with object, emergency landing - object - sign (contributing factor) ## Analysis The engine lost power when the 31-hour student pilot turned the airplane from downwind to base, and the pilot force-landed the airplane on a street. During the emergency landing, the left wing impacted a street sign and damaged the spar. The engine was test-run following the accident and no operational anomalies were noted. ## Factual narrative In information obtained by the National Transportation Safety Board investigator, the 31-hour student pilot reported the he had been practicing touch-and-go takeoffs and landings. Prior to takeoff, he performed a run-up in which he leaned the mixture. The student pilot had completed one touch-and-go and was in the airport traffic pattern when the loss of power occurred. He was turning from downwind to base, applied carburetor heat, extended the flaps 10 degrees, and pulled the throttle back. He noted that the airplane was descending excessively. He increased the throttle but the engine did not respond. The student pilot moved the throttle control back and forth but the engine revolutions per minute (rpm) did not increase. He could not recall what the engine rpm was indicating. He then declared an emergency and selected an emergency landing spot on a street. The left wing spar was bent when the wing impacted a street sign during the landing roll. The propeller continued to windmill until the airplane rolled to a stop. Following the accident, the Federal Aviation Administration accident coordinator test ran the Textron Lycoming O-320-E2D engine using the airplane's fuel system and onboard fuel. The engine powered normally. Throttle bursts were applied and no delay or loss in power was observed. ## Aircraft - Registration: [N1079M](https://openairdocs.org/aircraft/N1079M), registered now, S/N 17259802, built 1971 (OpenAirDocs) - Reported make and model: Cessna 172L - Registry model: [Cessna 172L](https://openairdocs.org/model/cessna-172l) (registry code 2072432) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17259802 - Engines: Textron Lycoming O-320-E2D reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: West Air Aviation - Registered owner: West Wind Aviation Inc.
