# NTSB MIA07CA040: Jim Garrison N11, N369JG, Titusville, FL, January 14, 2007 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Data collection · Final report - Date: January 14, 2007, 09:10 local (14:10 UTC) - Place: Titusville, FL - Coordinates: 28.616666, -80.831947 - Nearby events: https://openairdocs.org/map.md?lat=28.6167&lon=-80.8319&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - Parties: Orlando, Florida - NTSB case key (mKey): 65248 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA07CA040 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65248/pdf - Page: https://openairdocs.org/ntsb/MIA07CA040 ## Probable cause The failure of the pilot to abort the takeoff after becoming airborne during taxi testing, and the failure of the pilot to maintain airspeed after becoming airborne resulting in an inadvertent stall, uncontrolled descent, and in-flight collision with a tree. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Miscellaneous/other, takeoff - initial climb - aborted takeoff - not performed, pilot in command (cause) - Loss of control - in flight, takeoff - initial climb - airspeed - not maintained, pilot in command (cause) - stall - inadvertent, pilot in command - In flight collision with object, descent - uncontrolled - object - tree(s) ## Analysis The airplane stalled after takeoff and collided with a tree. The pilot stated that he previously ground looped the airplane in December 2006, which resulted in the necessity to replace the left wheel assembly. A borrowed left wheel assembly was installed with the brake drum facing outboard, rendering the left brake inoperative. The purpose of the accident flight was to perform taxi testing at increasing speeds in an effort to determine rudder effectiveness, and also for personal experience; no static engine run-up was performed before applying power to begin the taxi test. The airplane was taxied onto runway 15, and power was applied to begin the taxi test, but the airplane inadvertently became airborne. After realizing that the flight was airborne and there was insufficient runway remaining to land and stop the airplane, he applied full power and attempted to turn 45 degrees in order to land on a closed grass runway. The airplane climbed in ground effect, stalled, and collided with trees. He reported that the "...engine was 'overpropped' and thus not producing maximum horsepower." He also recommended more static testing of the engine/propeller combination. ## Factual narrative The pilot stated that he previously ground looped the airplane in December 2006, which resulted in the necessity to replace the left wheel assembly.

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.
