A Cessna 172S with a pilot-in-command and a check pilot flight instructor struck two Canada geese during final approach to runway 15. The pilot heard and felt a thump but maintained control without difficulty.

Incident Overview

The aircraft, a Cessna 172S, was on final approach to land on runway 15. The pilot-in-command was accompanied by a check pilot flight instructor. As the airplane descended through 50 feet above ground level, two Canada geese entered the pilots' field of view, flying from right to left.

Pilot Actions

The birds were initially shielded from the pilots' view by the aircraft structure until they passed the nose. The pilot-in-command decided not to take evasive action, instead choosing to remain prepared to control the airplane in the event of a collision. The pilot subsequently heard and felt a 'thump' as the geese struck the aircraft.

Aftermath

Despite the impact, the pilot did not experience any difficulty in controlling the airplane. The aircraft continued its approach and landing without further incident. No damage assessment or injuries were reported in the source.
