Incident Overview

Date: Monday 8 June 2020
Aircraft Type: Dornier 228-212
Owner/operator: Netherlands Coast Guard (Kustwacht)
Registration Number: PH-CGN
Location: Eindhoven Airport (EIN/EHEH) – ÿ Netherlands
Phase of Flight: Landing
Status: Minor
Casualties: Fatalities: 0 / Occupants: 2
Component Affected: Main WheelsMain Wheels
Category: Accident
An Aeroplane incident occurred at Eindhoven Airport when a Dornier aircraft, intended for circuit and landing operations at Schiphol, lost control during a stop and go. The flight crew experienced a sudden loss of control, resulting in a sharp rightward pull, ground loop, and subsequent contact with the runway. The aircraft sustained significant damage, including punctured tires, damaged main landing gear, and wing tip damage. The incident was attributed to a combination of factors, including the aircraft’s sensitivity to blocked wheels, exacerbated by braking action, a change in engine torque asymmetry, and throttle stagger. The blocked wheels were the primary limiting factor.An Aeroplane incident occurred at Eindhoven Airport when a Dornier aircraft, intended for circuit and landing operations at Schiphol, lost control during a stop and go.

Description

The aeroplane had taken off from Amsterdam Airport Schiphol with the intention of practising circuits, landings, and stop and goes, on Runway 03 at Eindhoven Airport. The Dornier then intended to return to Schiphol. During one stop and go, the flight crew suddenly lost control during the landing rollout. The aeroplane pulled sharply to the right after which it made a ground loop and ended up next to the runway. The flight crew remained unharmed. The left main landing gear and the left wing tip suffered serious damage and the left aileron was also damaged. Both tyres of the main wheels were punctured. Identified factors The condition of blocked wheels was the main factor that limited to easily maintain, or regain, directional control. As no technical evidence was found of any anomaly in the brake system, the wheels blocked as a result of braking action by the pilot. Contributing factors were: ? Higher sensitivity for blocked wheels and skidding as: – the aircraft was not equipped with anti-skid and blocked wheels protection, combined with – the operator?s practice to use a higher airspeed at touchdown with full flaps ? A change in engine torque asymmetry that ? in combination with pilot steering corrections – likely amplified an oscillation. This could happen due throttle stagger.
