What happened
The aircraft was conducting an approach and landing at Savannah when it encountered a left crosswind condition. As the plane touched down on the runway, it began to drift toward the left side of the pavement. Despite attempts to maintain alignment, the aircraft veered completely off the runway surface.
Once off the paved surface, the aircraft entered soft terrain immediately adjacent to the runway. The ground conditions were insufficient to support the weight and momentum of the landing gear, causing the nose gear to collapse under the stress. The pilot later reported that he believed air traffic control tower personnel had informed him the wind was coming from 030 degrees at 9 knots.
The investigation
Following the incident, investigators reviewed communication transcripts between the pilot and the tower. These records revealed a discrepancy in the information received by the pilot. Just before landing, the tower had actually reported the wind as being from 350 degrees at 12 knots. This contradicted the pilot's understanding of the wind direction and speed.
To verify the actual atmospheric conditions, investigators checked official weather data for Savannah at the time of the event. The recorded wind at 1353 EDT was from 040 degrees at 10 knots. While this differed slightly from the tower's verbal report, it confirmed a crosswind component that was more significant than what the pilot believed he had been told.
Findings
The primary factor leading to the loss of control was the aircraft's departure from the runway during the landing roll. This excursion was facilitated by the left crosswind and the pilot's misperception of the wind conditions. The collapse of the nose gear was a direct result of the aircraft leaving the hard surface and entering soft terrain, which could not withstand the impact forces.
The investigation highlighted a communication gap regarding critical flight information. The pilot operated under the assumption that the wind was from 030 degrees at 9 knots, whereas the tower provided data indicating a wind from 350 degrees at 12 knots. This misunderstanding likely affected the pilot's technique for correcting the drift during the final phase of the landing.
Safety message
Pilots must ensure they accurately interpret and verify wind reports from air traffic control, especially during crosswind landings. Miscommunication regarding wind direction and speed can lead to significant errors in aircraft control and runway alignment.
