Thomson 033 KSFB Bird Strike & Landing

A Thomson Airways Boeing 767 suffers a bird strike during takeoff and returns to Sanford.

2011-04-26 Orlando Sanford International Airport (KSFB), Florida

Summary

Shortly after departing Orlando Sanford International Airport, Thomson 033 reports ingesting a large bird into its left engine. The crew promptly requests to level off at 3,000 feet to assess the situation and coordinate a return to the field. The aircraft successfully executes an ILS approach and lands safely back at Sanford without further incident.

Analysis

This recording captures a textbook response to a bird strike during the critical departure phase of flight. Thomson 033, a "Heavy" aircraft (likely a Boeing 767), was departing Orlando Sanford (KSFB) when it encountered a bird. The pilot's immediate communication to the tower—"We took a big bird down the left engine"—indicates a significant ingestion event that required immediate termination of the climb and a return to the airport.

The crew demonstrated high situational awareness by requesting to "stop at 3,000 feet" and maintain runway heading. In aviation, this is a standard safety procedure: it allows the pilots to stabilize the aircraft, run the necessary emergency checklists, and assess whether the engine is still producing thrust or needs to be shut down, all while remaining in a safe block of airspace. By not continuing the climb, they avoided putting additional stress on the potentially damaged engine.

The transition between Sanford Tower and Orlando Departure was handled efficiently. The controller provided the crew with the option to return immediately or coordinate through departure control. The flight was vectored back for an ILS (Instrument Landing System) approach to Runway 9L. Despite the potential for a high-workload environment, the radio transmissions remained calm and professional from both the cockpit and the control tower.

Bird strikes are a common hazard in aviation, but ingesting a "big bird" into a high-bypass turbofan engine on a heavy jet can cause significant internal damage, including fan blade deformation or compressor stalls. The "Heavy" designation suggests the aircraft was carrying a significant fuel load for a transatlantic flight, which would make the aircraft very heavy for landing; however, the crew opted for an immediate return rather than fuel dumping, suggesting they prioritized getting on the ground quickly over landing weight considerations.
