Left Wing Strikes Tree During Approach to Unimproved Strip (N9880G)

Ozona, TX, US

On July 25, 1992, a Cessna 172L (registration N9880G) operated by Wester, Willie J. was involved in an aviation accident near Ozona, TX. Investigators recorded the probable cause as: The pilot's failure to align the airplane with the unimproved strip prior to impact, which resulted in the left wing striking a tree and the nose gear separating upon contact with soft dirt. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An airplane sustained significant damage after its left wing struck a tree during the approach to an unimproved strip, leading to a nose gear collapse and the aircraft coming to rest inverted.

What happened

During the final approach phase to an unimproved airstrip, the pilot encountered difficulties aligning the aircraft with the runway centerline. As the airplane descended toward the landing zone, the left wing made contact with a tree situated along the approach path. This impact caused the aircraft to yaw sharply sideways, disrupting its intended flight path.

The pilot was unable to correct the alignment before the nose gear contacted the soft dirt surface located to the left of the designated strip. The force of this impact resulted in the immediate separation of the nose landing gear assembly. Following the structural failure of the nose gear, the airplane continued forward and eventually came to a stop in an inverted position on the ground.

The investigation

Examination of the accident site revealed that the primary damage originated from the initial contact with the tree during the approach. Subsequent inspection confirmed that the nose landing gear had separated from the airframe due to the impact with the soft dirt surface off the side of the strip. The aircraft's final resting position was upside down, indicating a complete loss of controlled flight during the landing sequence.

Findings

The sequence of events indicates that the pilot failed to establish proper alignment with the unimproved strip prior to touchdown. The contact with the tree on the left wing compromised the aircraft's stability and orientation. The subsequent impact with the soft ground off the side of the runway led to the structural failure of the nose gear. Fuel exhaustion is not cited as a factor; rather, the accident was caused by improper alignment during approach.

Safety message

Pilots operating into unimproved strips must ensure proper aircraft alignment well before reaching the touchdown zone. Awareness of obstacles such as trees along the approach path is critical to preventing wing strikes and subsequent loss of control.

Probable cause

The pilot's failure to align the airplane with the unimproved strip prior to impact, which resulted in the left wing striking a tree and the nose gear separating upon contact with soft dirt.
