# NTSB ANC99LA081: Champion 7GCBC, N5149X, Anchorage, AK, June 24, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 23, 1999, 18:00 local (Jun 24, 1999, 02:00 UTC) - Place: Anchorage, AK - Coordinates: 61.160449, -149.989456 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=61.1604&lon=-149.9895&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 23, 2000 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 46653 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC99LA081 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/46653/pdf - Page: https://openairdocs.org/ntsb/ANC99LA081 ## Probable cause The pilot's failure to maintain an adequate airspeed, and subsequent inadvertent stall. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, approach - vfr pattern - final approach - airspeed - low, pilot in command (cause) - stall - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis The certificated private pilot was practicing touch and go landings. The pilot stated on his fifth touch and go landing, while on short final with a left crosswind, 'the wind quit and I just sunk.' He added: 'I may have let my airspeed get too low at that time.' The pilot said he applied full power and full back pressure on the elevator control. He said the left wing stalled and the airplane bounced about 30 feet short of the runway. The airplane came to a stop at the approach end of the runway. The pilot stated 'I applied too much back pressure and stalled it.' The pilot reported there were no preaccident mechanical anomalies with the airplane. The airplane received substantial damage to the wings. Wind conditions at the time of the accident were reported to be light and variable. ## Factual narrative On June 23, 1999, about 1800 Alaska daylight time, a wheel equipped, Champion 7GCBC airplane, N5149X, sustained substantial damage during landing at the Lake Hood Airstrip, Anchorage, Alaska. The airplane was being operated as a visual flight rules (VFR) local area flight under Title 14, CFR Part 91 when the accident occurred. The airplane was registered to the pilot. The certificated private pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed, and no flight plan was filed. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on June 24, the pilot reported that he was practicing touch and go landings. The pilot stated on his fifth touch and go landing, while on short final with a left crosswind, "the wind quit and I just sunk." He added: "I may have let my airspeed get too low at that time." The pilot said he applied full power and full back pressure on the elevator control. He said the left wing stalled and the airplane bounced about 30 feet short of the runway. The airplane came to a stop at the approach end of the runway. The pilot stated "I applied too much back pressure and stalled it." The pilot reported there were no preaccident mechanical anomalies with the airplane. The airplane received substantial damage to the wings. Wind conditions at the time of the accident were reported to be light and variable. ## Aircraft - Registration: [N5149X](https://openairdocs.org/aircraft/N5149X), registered now, S/N 103, built 1969 (OpenAirDocs) - Reported make and model: Champion 7GCBC - Registry model: [Champion 7GCBC](https://openairdocs.org/model/champion-7gcbc) (registry code 21101PK) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 103 - Engines: Lycoming O-320-A2B 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: James R.
