Incident Overview

Date: Saturday 29 October 1988
Aircraft Type: Canadair CL-600-1A11 Challenger 600
Owner/operator: Griffin Records Inc dba Avjet Corporation
Registration Number: N909MG
Location: Aspen Pitkin County Airport (ASE/KASE), Aspen, CO – ÿ United States of America
Phase of Flight: Take off
Status: Substantial
Casualties: Fatalities: 0 / Occupants: 7
Component Affected: NewWheel Steering System (NWSS) and Thrust ReversersNewWheel Steering System (NWSS) and Thrust Reversers
Investigating Agency: NTSBNTSB
Category: Accident
On October 29, 1988, a Canadair CL-600-1A11 Challenger 600 jet, N909MG, experienced a significant incident during an aborted takeoff and collision with two parked airplanes at Aspen Pitkin County Airport (ASE/KASE). The pilot, Lieutenant Peter, initiated the aborted takeoff and subsequently experienced a series of steering and control issues. The aircraft’s flight attendant and four passengers were not injured. The PLT utilized the NewWheel Steering System (NWSS) during taxiing to the runway, and while taxiing, he initiated a 180-degree turn and a roll, failing to activate thrust reversers. Subsequent acceleration of the aircraft without thrust reversers resulted in a collision with two parked airplanes. The PLT reported difficulty in steering the aircraft during the roll and the pilot subsequently delayed thrust levers to idle, applying maximum braking and reverse thrust. The aircraft ultimately impacted three parked aircraft before stopping. Investigation revealed that the NWSS and thrust reversers were in good working order, with no mechanical failures or malfunctions observed during post-accident examinations. The incident was likely caused by the pilot’s failure to follow established takeoff procedures and direct orders, coupled with a lack of timely abort action.On October 29, 1988, a Canadair CL-600-1A11 Challenger 600 jet, N909MG, experienced a significant incident during an aborted takeoff and collision with two parked airplanes at Aspen Pitkin County Airport (ASE/KASE).

Description

On October 29, 1988, at about 13:55 local time, a Canadair CL-600-1A11 Challenger 600 jet, N909MG, sustained substantial damage during an aborted takeoff and collision with two parked airplanes at Aspen Pitkin County Airport (ASE/KASE), Aspen, Colorado. The two pilots sustained minor injuries. The flight attendant and four passengers were not injured. THE PLT USED THE NOSEWHEEL STEERING SYSTEM (NWSS) WHILE TAXIING FM THE FBO TO THE RWY. HE BACK-TAXIED DOWN THE RWY & MADE A 180 DEG TURN, THEN WITHOUT STOPPING, HE BEGAN THE TAKEOFF ROLL. THERE WERE NO RPRTD MALFUNCTIONS OF THE NWSS BEFORE COMMENCING THE TAKEOFF. THE PLT STATED HE HAD DIFFICULTY IN STEERING THE ACFT ON THE TAKEOFF ROLL. AS THE ENGS SPOOLED UP, THE ACFT TRACKED TO THE RGT OF THE RWY CENTERLINE. SUBSEQUENTLY, AS HE CORRECTED WITH THE NWSS, THE ACFT VEERED LEFT, THEN RIGHT, AS IT WAS ACCELERATING. THE PLT INITIATED ABORT PROCEDURES BEFORE REACHING 80 KTS, BUT HE WAS UNABLE TO REGAIN DRCTNL CTL. HE STATED HE RETARDED THE THRUST LEVERS TO IDLE, APPLIED MAX BRAKING & SELECTED REVERSE THRUST, BUT THE ACFT ACCELERATED WHEN THE ENGS SPOOLED UP WITHOUT ACTIVATION OF THE THRUST REVERSERS. HE SHUT DOWN THE ENGS, BUT THE ACFT HIT 3 PARKED ACFT BEFORE STOPPING. THE ACFT WAS EQUIPPED WITH AN EARLY MODEL (DOWTY ROTOL) NWSS. POST-ACDNT EXAMS OF THE NWSS & THRUST REVERSERS REVEALED NO EVIDENCE OF A MECHANICAL MALFUNCTION OR FAILURE. Probable Cause: THE PIC’S FAILURE TO FOLLOW APPROVED PROCEDURES AND DIRECTIVES; THE PIC’S FAILURE TO ATTAIN/MAINTAIN DIRECTION CONTROL OF THE AIRPLANE, THE PIC’S FAILURE TO ABORT THE TAKEOFF IN A TIMELY MANNER; AND THE PIC’S FAILURE TO FOLLOW PROPER ABORTED TAKEOFF PROCEDURES.
