# NTSB ATL97LA018: Piper PA-30-160, N7392Y, Cartersville, GA, November 11, 1996 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: November 11, 1996, 12:30 local (17:30 UTC) - Place: Cartersville, GA - Coordinates: 34.160541, -84.800628 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.1605&lon=-84.8006&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report August 29, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 3807 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL97LA018 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/3807/pdf - Page: https://openairdocs.org/ntsb/ATL97LA018 ## Probable cause the flight instructor's (CFI's) inadequate supervision by failing to ensure that directional control of the aircraft was maintained, during a simulated engine failure. The student pilot's delay in performing the appropriate single-engine emergency procedure was a related factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - airspeed(vmcg) - not attained - engine shutdown - performed, pilot in command(cfi) - emergency procedure - delayed, dual student (contributing factor) - directional control - not maintained, flightcrew (cause) - supervision - inadequate, pilot in command(cfi) (cause) - On ground/water encounter with terrain/water, takeoff - roll/run - Main gear collapsed, takeoff - landing gear,main gear - overload ## Analysis The flight was being conducted to provide multi-engine training to the single-engine, rated, commercial student. During a takeoff roll on runway 01, the left engine was shut off below Vmcg by the flight instructor (CFI) to simulate an engine failure. The dual student failed to reduce the power on the right engine in a timely manner to prevent the airplane from yawing to the left. The CFI stated he was unable to recover control of the airplane in time to prevent its veering off of the runway. The airplane then encountered unfavorable terrain, and the left main gear collapsed. The CFI and the student did not report any mechanical problems with the airplane. ## Factual narrative On November 11, 1996, about 1230 eastern standard time, a Piper PA-30-160, N7392Y, collided with the ground adjacent to the runway during the takeoff roll at Cartersville, Georgia. The airplane was operated by the pilot under the provisions of Title 14 CFR Part 91, and visual flight rules(VFR). A VFR flight plan was filed for the dual instructional flight. There were no injuries to the commercial instructor, nor to the dual student, and the airplane was substantially damaged. Origination of the flight was Dobbins Air Force Base, Marietta, Georgia, about 1130, on the same day. The flight was being conducted to provide multi-engine training to the single engine rated commercial student. During a takeoff roll on runway 01, at the airport selected for training, the left engine was shut off by the instructor to simulate an engine failure. The pilot under instruction failed to reduced the power on the right engine in a timely manner to prevent the aircraft from yawing to the left. The instructor stated he was unable to recover control of the airplane in time to prevent its veering off of the runway. Examination of the accident site disclosed that the airplane veered off of the left side of the runway at approximately 1500 ft. down the runway. Further examination revealed that the left main gear collapsed and the airplane rested approximately 120 degrees from the original runway heading. The CFI and the student did not report a mechanical problem with the airplane. ## Aircraft - Registration: [N7392Y](https://openairdocs.org/deregistered/N7392Y-2013-08-23), registration cancelled 2013-08-23, S/N 30-448, built 1964 (OpenAirDocs) - Reported make and model: Piper PA-30-160 - Registry model: [Piper PA-30](https://openairdocs.org/model/piper-pa-30) (registry code 7103002) (OpenAirDocs) - Registry engine: [Lycoming IO-320 series](https://openairdocs.org/engine/lycoming-io-320-series) (registry code 41509, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 30-448 - Airframe hours: 4794 - Engines: Lycoming IO-320-BIA 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Atlanta Navy Flying Club - Registered owner: John Brown - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, May 16, 1996, 904 hours before - Departed: MGE, MARIETTA, GA - Destination: VPC, GA - Flight plan: Military VFR - Airport: VPC, Cartersville, runway 1, 5,000 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

Student pilot added power on simulated loss of engine, aircraft ran off left side of runway. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
