2002-10-10: Cessna 152 (N520SU) — Oklahoma State University Flight Center (tulsa) — Tulsa, OK

Tulsa, OK, US

On October 10, 2002, a Cessna 152 (registration N520SU) operated by Oklahoma State University Flight Center (tulsa) was involved in an aviation accident near Tulsa, OK. Investigators recorded the probable cause as: The pilot's failure to maintain adequate airspeed and control during a short-field approach, which resulted in a stall and subsequent impact with the runway. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.

A pilot practicing a short-field approach misjudged alignment and touchdown, leading to an excessive pitch-up that caused a stall and hard landing off-centerline.

What happened

The incident occurred while the pilot was conducting flight training maneuvers focused on short-field landing techniques. The primary objective was to achieve precise touchdown placement, commonly referred to as "hitting the numbers" on the runway surface. During the final approach phase, the pilot acknowledged that the aircraft was not properly aligned with the runway centerline.

Upon touchdown, the aircraft experienced a hard impact followed by a bounce. In an attempt to abort the landing or maintain altitude, the pilot applied additional engine power and pulled back on the controls, raising the nose to an excessively high angle of attack. This maneuver exceeded the critical angle of attack for the aircraft's current configuration.

Consequently, the airplane entered a stall condition. The loss of lift caused the aircraft to descend rapidly and impact the runway surface. The final resting position was located to the left of the runway centerline. At the time of impact, the aircraft was in a nose-low attitude with the left wing lower than the right.

The investigation

The investigation relied primarily on the pilot's account of the events leading up to the accident. There were no mechanical failures reported prior to the stall. The sequence of events indicates that the combination of poor alignment, hard touchdown, and excessive pitch input during a power application led directly to the aerodynamic stall.

Findings

  • The pilot failed to maintain proper runway alignment during the approach.
  • Excessive nose-up pitch attitude was applied after touchdown.
  • The aircraft stalled due to exceeding the critical angle of attack.
  • Impact occurred off-centerline with a left-wing-down orientation.

Probable cause

The pilot's failure to maintain adequate airspeed and control during a short-field approach, which resulted in a stall and subsequent impact with the runway.
