## Probable cause

The flight instructor's inadequate supervision of the dual student, and his failure to maintain control of the airplane.  A factor associated with the accident was the dual student's excessive application of the brakes.

## 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
  - supervision - inadequate, pilot in command(cfi) (cause)
  - aircraft control - not maintained, pilot in command(cfi) (cause)
  - brakes(normal) - excessive, dual student (contributing factor)
  - terrain condition - runway
- Nose over, landing - roll

## Analysis

The owner of the accident airplane reported that the certificated flight instructor was conducting a Title 14, CFR Part 91 instructional flight giving tailwheel instruction and practicing wheel landings, when the dual student applied the brakes too heavily, and the airplane nosed over.  The owner said the instructor reported damage to the wing leading edges, rudder and lift struts.  The owner indicated there were no known mechanical anomalies with the airplane prior to the accident.

## Factual narrative

On August 5, 2005, about 1300 Alaska daylight time, a tailwheel equipped  Aviat Husky A-1 airplane, N8XJ, sustained substantial damage when it nosed over during the landing roll at the Goose Bay Airport, about 8 miles north of Anchorage, Alaska.  The airplane was being operated by the certificated flight instructor as a visual flight rules (VFR) instructional flight under Title14, CFR Part 91 when the accident occurred.  The instructor and dual student were not injured.  Visual meteorological conditions prevailed, and no flight plan was filed.  The flight departed Lake Hood Strip, Anchorage, about 1145.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on August 5, the owner of the airplane said the instructor was giving tailwheel instruction, and practicing wheel landings when the dual student applied the brakes too heavily, and the airplane nosed over.  The owner said the instructor reported damage to the wing leading edges, rudder and lift struts.  The owner said there were no known mechanical anomalies with the airplane prior to the accident.

The NTSB Form 6120.1 sent to the flight instructor was returned unclaimed.

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.
