Incident Overview
Date: Friday 19 November 1999
Aircraft Type: Boeing 737-36N
Owner/operator: Air France
Registration Number: F-GRFA
Location: Paris-Charles de Gaulle Airport (CDG/LFPG) –
ÿ France
Phase of Flight: Take off
Status: Substantial, repaired
Casualties: Fatalities: 0 / Occupants: 61
Component Affected: Aircraft Thrust Control System (specifically engine thrust levers and rudder)Aircraft Thrust Control System (specifically engine thrust levers and rudder)
Investigating Agency: BEABEA
Category: Accident
A pilot initiated a lateral movement of the aircraft during takeoff, utilizing asymmetrical thrust and rudder control. This resulted in the aircraft deviating to the left runway edge.A pilot initiated a lateral movement of the aircraft during takeoff, utilizing asymmetrical thrust and rudder control. This resulted in the aircraft deviating to the left runway edge.
Description
During take off, the captain applied power with a shift of several degrees in TLA and attempt to control the direction using the asymmetrical thrust while the copilot was not able to control the direction of the aircraft with the rudder pedal. The aircraft ran laterally off the runway to the left. Causes The failure to apply the engine thrust procedure during the alignment did not allow the thrust asymmetry caused by the prior shifting of the thrust levers to be corrected. This asymmetry, accentuated by the inappropriate use of the thrust controls, led to the runway excursion.
Primary Cause
Incorrect application of engine thrust during alignment, leading to asymmetric thrust and subsequent runway excursion.Incorrect application of engine thrust during alignment, leading to asymmetric thrust and subsequent runway excursion.Share on:
