A San Antonio aerospace firm was sued after a UPS jet engine fell off before a deadly crash

The UPS jet crash that stunned aviation

On November 4, 2025, a UPS Airlines MD‑11 cargo jet lost its left engine during takeoff from Louisville Muhammad Ali International Airport, resulting in a devastating crash that killed at least 14 people and injured more than 20, according to early reports.

Investigators said preliminary evidence indicates the left engine detached during takeoff, and the NTSB launched an investigation into maintenance records and potential mechanical factors.

San Antonio firm named in lawsuit over maintenance

The family of Carlos Arias Fernandez filed a wrongful death lawsuit in Texas against ST Engineering San Antonio Aerospace, alleging negligence in maintaining the MD‑11 that lost its engine.

The lawsuit claimed the company had failed to ensure the aging aircraft was safe to fly and sought over $1 million in damages. Plaintiffs argued that the maintenance practices had directly contributed to the fatal crash.

Maintenance timeline critical to legal claims

VT San Antonio Aerospace performed extensive maintenance on the MD‑11 from September 3 to October 18, 2025, including structural inspections and engine attachment checks.

Plaintiffs alleged these procedures were conducted negligently, potentially causing the fatal failure.

The timeline of maintenance was central to the lawsuit, as families argued that errors or oversights during servicing directly contributed to the detachment of the engine, causing the deadly crash.

Engine pylon cracks spotlighted by investigators

The National Transportation Safety Board discovered fatigue cracks in the MD‑11’s engine pylon during its investigation.

These structural flaws likely caused the engine to detach during takeoff. Experts suggest that earlier inspections should have detected these critical issues.

Plaintiffs argue that inadequate inspections by ST Engineering San Antonio Aerospace directly contributed to the mechanical failure, which caused the plane to crash, killing 14 people and injuring others on the ground.

Broader lawsuits named UPS, Boeing, GE Aerospace

Beyond the San Antonio firm, wrongful death lawsuits include UPS Airlines, Boeing, and GE Aerospace. Plaintiffs allege all parties shared liability for the crash. The claims focus on potential negligence in aircraft maintenance.

Design and oversight, arguing that the MD‑11 was unsafe to operate. Families seek accountability from every responsible party, citing both mechanical failures and management decisions as contributing factors to the catastrophic Louisville crash in November 2025.

Family lawsuits highlighted individual losses

Victims’ families, including Trina Chavez and Angela Anderson, filed separate claims to highlight personal loss and tragedy. Lawsuits allege the MD‑11 was unfit to fly, emphasizing the human cost of the crash.

These legal actions describe emotional devastation, financial burdens, and the trauma of losing loved ones.

Lawyers seek justice while documenting the human impact, aiming to hold both maintenance firms and manufacturers accountable for neglect that contributed to the deadly accident.

Lawyers accused UPS of prioritizing profit

Attorney Robert Clifford argued the MD‑11 involved in the crash was “old and tired,” suggesting UPS Airlines might have prioritized profits over safety.

Lawyers claimed the company neglected enhanced inspections, allowing an aging aircraft to operate without proper scrutiny.

These allegations form a core part of the wrongful death lawsuit, asserting that profit motives contributed to unsafe conditions. Families seek accountability from UPS alongside maintenance and manufacturer defendants.

The MD‑11’s age became central to arguments

At 34 years old, the UPS MD‑11 was among the oldest planes in its fleet. Plaintiffs argued the jet’s age, combined with insufficient inspections, directly contributed to the structural failure.

Lawyers stressed that aging aircraft required enhanced safety measures, and failure to follow them reflects negligence. The lawsuit emphasizes that the crash might have been prevented if the plane had undergone proper maintenance and monitoring.

FAA grounded aging MD‑11 fleet after crash

After the November 2025 crash, the Federal Aviation Administration ordered immediate inspections of all remaining MD‑11 freighters. Authorities grounded several planes to prevent similar accidents.

This regulatory response reflected growing concern over mechanical integrity and maintenance oversight in aging aircraft.

Federal investigators focused on engine mounts and structural pylon attachments, ensuring any potentially unsafe aircraft were removed from service until defects could be repaired.

Legal filings revealed graphic accident sequence

Court documents described Flight 2976’s left engine detachment during takeoff, sparking a chain of events that led to the crash. Sparks ignited nearby structures, the jet struck buildings, and 14 people died.

These details are crucial in lawsuits against maintenance, airline, and manufacturer defendants, demonstrating the fatal consequences of mechanical failure.

Families cite this sequence to strengthen negligence claims, emphasizing that preventive maintenance could have avoided the deadly incident.

Maintenance details intensified negligence claims

Documents revealed VT San Antonio Aerospace crews addressed wing cracks, corrosion, and lubrication during the MD‑11’s last servicing. Lawyers argued, however, that deeper structural flaws were missed, including pylon fatigue.

These oversights were cited as direct causes of the engine detachment, which ultimately caused the crash. Plaintiffs emphasized that proper inspections and repairs would have prevented the catastrophe, highlighting alleged negligence in both procedures.

Industry scrutiny grew over MD‑11 safety

Aviation experts and families argued that the MD‑11’s service history and inspection gaps increased the risk of catastrophic failures. The plane’s age, combined with previous mechanical concerns, illustrates vulnerabilities in cargo fleets.

This scrutiny extended to airlines, maintenance firms, and manufacturers, prompting calls for stricter safety measures. Lawsuits highlight these risks, suggesting that better oversight, updated protocols, and structural monitoring could prevent tragedies similar to the Louisville crash.

What happened next in the legal battle

With multiple lawsuits pending against ST Engineering, UPS, Boeing, and GE Aerospace, lengthy discovery and court proceedings were expected. Plaintiffs seek justice, compensation, and safety reforms to prevent future tragedies.

Legal experts anticipated a complex trial over negligence, maintenance oversight, and manufacturer responsibility.

Families aimed to hold every party accountable for the 2025 Louisville crash, using detailed records, expert testimony, and FAA findings to support their claims in court.

Do you think maintenance firms should face criminal liability when alleged errors contribute to a fatal crash, or should accountability stay limited to civil lawsuits?
