## Probable cause

The pilot not following the emergency landing gear extension procedures.  Factors were the failure of the hydraulic motor, and the landing gear locks not engaged.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Gear collapsed, landing - roll
  - hydraulic system,motor - failure,total (contributing factor)
  - emergency procedure - not followed, pilot in command (cause)
  - landing gear,gear locking mechanism - not engaged (contributing factor)

## Analysis

The airplane's right main landing gear collapsed on landing.  The pilot reported that he was unable to get a gear down indication during the landing approach.  The pilot did not use the emergency landing gear extension.  A postaccident examination of the airplane revealed that the hydraulic system motor had an open electrical circuit.  No anomalies were found with respect to the emergency landing gear extension system.

## Factual narrative

On August 12, 2001, at 1558 eastern daylight time, a Globe GC-1B, N80917, owned and piloted by an airline transport pilot, sustained substantial damage when the right main landing gear collapsed while landing on runway 28 (6,501 feet by 150 feet, dry asphalt), at the Cherry Capital Airport, Traverse City, Michigan.  The 14 CFR Part 91 personal flight was operating in visual meteorological conditions and was not on a flight plan.  The pilot, who was the sole occupant, reported no injuries.  The flight originated from the Manistee County-Blacker Airport, Manistee, Michigan, at an undetermined time.

The pilot reported to Federal Aviation Administration officials that he was unable to get a gear down indication during the landing approach.  The pilot did not use the emergency landing gear extension. A postaccident examination of the airplane revealed that the hydraulic system motor had an open electrical circuit.  No anomalies were found with respect to the emergency landing gear extension system.
