# NTSB MIA99LA056: Piper PA-22-150, N7357D, Chamblee, GA, October 25, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 25, 1998, 11:10 local (16:10 UTC) - Place: Chamblee, GA - Coordinates: 33.900089, -84.300857 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=33.9001&lon=-84.3009&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 4 uninjured - Status: Completed, report August 27, 1999 - Report: Approved by Office Director - NTSB case key (mKey): 45535 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA99LA056 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45535/pdf - Page: https://openairdocs.org/ntsb/MIA99LA056 ## Probable cause The pilot's excessive use of right wheel brake to correct for a left drift during landing rollout resulting in a ground loop to the right and the left wing contacting the runway. ## 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 - brakes(normal) - excessive, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command - Dragged wing,rotor,pod,float or tail/skid, landing - roll ## Analysis During landing, as the tail wheel touched down, the aircraft began to drift to the left. The pilot applied right rudder and then right wheel brake in an attempt to correct the drift. The aircraft then ground looped to the right and the left wing contacted the runway. Postcrash examination of the left wheel brake and tail wheel steering showed no evidence of mechanical failure or malfunction. ## Factual narrative On October 25, 1998, about 1110 eastern standard time, a Piper PA-22-150, N7357D, registered to an individual, ground looped and struck the left wing on the runway, during landing at DeKalb-Peachtree Airport, Chamblee, Georgia, while on a Title 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the airline transport-rated pilot and one passenger were not injured. The flight originated from Gainesville, Georgia, the same day, about 1040. The pilot stated that during landing roll, as the tailwheel touched down, the aircraft began to veer to the left. He applied right rudder and then right wheel brake to control the left drift and the aircraft then ground looped to the right. As the aircraft ground looped, the left wing contacted the runway. After the accident, examination of the aircraft's left wheel brake and tailwheel by an aircraft mechanic showed no evidence of mechanical failure or malfunction. (See attached letters) The aircraft was reported to have received minor damage when FAA inspectors spoke with the pilot after the accident. As repairs were being made to the aircraft, the left wing spars were found to be bent. This damage was reported to FAA and NTSB on December 17, 1998. ## Aircraft - Registration: [N7357D](https://openairdocs.org/aircraft/N7357D), registered now, S/N 22-5155, built 1957 (OpenAirDocs) - Reported make and model: Piper PA-22-150 - Registry model: [Piper PA-22-150](https://openairdocs.org/model/piper-pa-22-150) (registry code 7102210) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-5155 - Airframe hours: 1864 - Engines: Lycoming O-320-A2B 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Neal H.Ferguson - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 29, 1998, 16 hours before - Departed: GVL, GAINESVILLE, GA - Airport: PDK, Peachtree-Dekalb, runway 2R, 6,001 × 100 ft, concrete ## Flight crew As NTSB recorded them.

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.
