Loss of Hydraulic Systems Leads to Emergency Landing and Tire Blowout for Continental Airlines Flight 354 (N556NY)

Newark, NJ, US

On July 26, 1989, a Douglas DC-9-30 (registration N556NY) operated by Continental Airlines was involved in an aviation accident near Newark, NJ. Investigators recorded the probable cause as: RUPTURE OF A FLEXIBLE HIGH PRESSURE HYDRAULIC LINE IN THE 'A' HYDRAULIC SYSTEM, DUE TO CHAFING OF THE STEEL BRAID COVERING, WHICH ALLOWED THE SYSTEM PRESSURE AND QUANTITY TO BE COMPLETELY DEPLETED. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.

Continental Airlines Flight 354 experienced loss of left hydraulic system and decreasing right system quantity. Crew shut down both pumps and performed emergency landing at Newark, where left tires blew out at 80 knots, causing the aircraft to swerve left off centerline.

Incident Overview

Continental Airlines Flight 354 encountered a hydraulic system failure during flight. The crew noted a loss of the left hydraulic system and a subsequent decrease in hydraulic quantity from the right system. Anticipating a potential loss of both hydraulic systems, the flight crew shut down both hydraulic pumps and declared an emergency.

Emergency Landing

The aircraft diverted to Newark International Airport in New Jersey for an emergency landing. The approach and touchdown were uneventful. However, as the aircraft decelerated, at approximately 80 knots groundspeed, the left main landing gear tires failed.

Post-Landing Events

Following the tire failure, the aircraft began to veer to the left. The crew maintained control as the airplane came to a stop approximately 30 feet left of the runway centerline. Emergency services responded, and the aircraft was subsequently towed from the runway.
