On February 4, 1998, Eva Air flight 611, a Boeing 747-200B registered as B-18255, crashed into the Taiwan Strait shortly after takeoff from Chiang Kai-shek International Airport. The accident resulted in the loss of all 197 passengers and crew on board and remains a pivotal case in aviation safety reviews for Taiwan.
Investigations revealed a series of maintenance and procedural failures, including improper repairs to the aircraft tail section, which ultimately led to in-flight structural separation. The incident prompted sweeping regulatory changes in maintenance oversight and training across Taiwan’s aviation sector.

Flight 611 Operational Timeline
Departure and Initial Climb
Flight 611 departed Chiang Kai-shek International Airport on schedule in the evening, carrying 194 passengers and three crew. During the initial climb, the aircraft experienced no immediate indications of distress from the cockpit.
In-Flight Structural Failure
Approximately 21 minutes into the flight, the tail section separated due to failed repairs, causing an immediate loss of control. The aircraft rapidly descended into the Taiwan Strait, where it was later recovered with no survivability.
Investigation and Reporting
The Aviation Safety Council of Taiwan led the investigation, identifying critical lapses in maintenance documentation, inadequate supervision, and failure to follow approved repair procedures as root causes.
Regulatory and Safety Reforms
Aircraft Maintenance Oversight
Authorities overhauled certification processes for repair stations, introducing stricter audits, real-time data reporting, and mandatory re-validation of major repairs to prevent recurrence.
Pilot Training and Crew Resource Management
Training programs were enhanced to emphasize cross-checking, assertive communication, and rapid response to abnormal flight conditions, ensuring early detection of potential control issues.
Passenger Impact and Legal Proceedings
Victim Families and Compensation
Family members pursued civil claims against Eva Air and maintenance providers, resulting in settlements that underscored corporate responsibility and the need for transparent investigations.
Industry Reputation and Policy Shifts
The crash influenced regional policy, leading to tighter coordination between Taiwanese regulators and international bodies to align maintenance standards and incident reporting frameworks.
Fleet and Operational Context
Eva Air’s Boeing 747 Operations
Following the accident, Eva Air gradually phased out its Boeing 747 fleet in favor of more fuel-efficient wide-body aircraft, reflecting both safety considerations and market dynamics in long-haul routes.
Key Takeaways
- Strict adherence to approved maintenance procedures is critical for aircraft structural integrity.
- Robust cross-checking and communication among cockpit crew can mitigate in-flight emergencies.
- Transparent investigations and regulatory reforms help restore public trust and enhance aviation safety.
- Continuous training updates ensure that crews and maintenance personnel respond effectively to emerging risks.
- Industry collaboration between regulators and airlines fosters safer operational standards across regions.
