Aircraft Type: Learjet 35
Owner/operator: Mid-Atlantic Jet Charter
Registration Number: N69PS
Location: Atlantic City International Airport, NJ (ACY) – ÿ United States of America
Phase of Flight: Take off
Status: Substantial, repaired
Casualties: Fatalities: 0 / Occupants: 10
Component Affected: TiresTires
Investigating Agency: NTSBNTSB
Category: Accident
A Learjet 35, N69PS, experienced significant damage during an aborted takeoff at Atlantic City International Airport, New Jersey. No injuries occurred. The aircraft was scheduled for Newark, New Jersey. The pilot initiated takeoff on runway 13, 10,000 feet long and 180 feet wide. The pilot stated the aircraft ‘pulled’ left before reaching V1 (takeoff decision speed) and experienced difficulty maintaining directional control. He aborted the takeoff, but couldn’t stop on the remaining runway. The plane crossed a concrete slab supporting an approach light and collapsed the main gear. The aircraft came to a stop 446 feet from the departure end of the runway, with significant tire damage ? outer left tire, left inner tire, and both right main tires blown. The pilot-in-command was unable to obtain reverse thrust due to missing checklist items and failure to deploy the drag chute. The under-inflated tires, resulting from improper maintenance, were a probable cause.A Learjet 35, N69PS, experienced significant damage during an aborted takeoff at Atlantic City International Airport, New Jersey.

Description

A Learjet 35, N69PS, sustained substantial damage during an aborted takeoff at the Atlantic City International Airport, New Jersey. There were no injuries. The airplane was destined for Newark, New Jersey. The crew taxied to and was cleared for takeoff on runway 13, which was 10,000 feet long and 180 feet wide. The pilot in command said that during takeoff, the airplane ‘pulled’ left before reaching V1 (takeoff decision speed) and he had difficulty maintaining directional control. He initiated an abort, but could not stop on the remaining runway. The plane crossed a concrete slab that previously supported an approach light and the main gear collapsed. The plane stopped 446 feet from the departure end of the runway. The outer left tire had blown during the takeoff roll, followed by the left inner tire and both right main tires. The pilot in command was unable to obtain reverse thrust because the reversers were not armed before takeoff. This was not included on the checklist that was provided to the flightcrew. Also, the pilot in command did not deploy the drag chute. Company maintenance personnel indicated the tires had been under-inflated when they were built up and installed, several days before the accident and that the tires had not been checked or reinflated after buildup. Probable cause: Under-inflation of the tires, due to improper maintenance, which resulted in overheating and subsequent tire failure; the incorrect checklist that was provided to the aircrew; and failure of the pilot-in-command to deploy the drag chute, when the thrust reversers did not operate.

Primary Cause

Under-inflation of tires due to improper maintenance, resulting in overheating and subsequent tire failure.Under-inflation of tires due to improper maintenance, resulting in overheating and subsequent tire failure.
