Incident Overview

Date: Friday 5 May 2000
Aircraft Type: Beechcraft 99
Owner/operator: Northwestern Air
Registration Number: C-GNAL
Location: Fort Smith, NT – ÿ Canada
Phase of Flight: Approach
Status: Substantial, repaired
Casualties: Fatalities: 0 / Occupants: 2
Component Affected: Right Main GearRight Main Gear
Category: Accident
A Beech 99 aircraft, PLR 799, experienced a catastrophic landing due to a collapsed right main gear during a local VFR training flight at Fort Smith. The aircraft landed on a gravel crosswind runway, resulting in damage to the right wing, propeller, and gear. The pilot initiated a sequence of actions involving gear recycling and overflying a ground observer, ultimately leading to the collapse of the RH gear during touchdown.A Beech 99 aircraft, PLR 799, experienced a catastrophic landing due to a collapsed right main gear during a local VFR training flight at Fort Smith.

Description

The crew of PLR 799, a Beech 99, was on a local VFR training flight at Fort Smith and when the aircraft landed on Runway 02, the right main gear collapsed. The aircraft sustained damage to the right wing, propeller and gear. When the landing gear was selected down during the approach, the RH gear remained indicating “In Transit”. After recycling the gear with the same result, the crew overflew a ground observer with the gear up (the RH gear remained down), then with the gear down (all 3 gear appeared to be down in normal position). They then landed on the gravel crosswind runway, and at touchdown, the RH gear collapsed.

Primary Cause

Gear failure during landing due to a combination of factors, potentially including a sudden shift in weight distribution or a mechanical failure.Gear failure during landing due to a combination of factors, potentially including a sudden shift in weight distribution or a mechanical failure.
