1989-08-12: Mooney M20K (N252WW) — Walter E. Gray, Inc. — Marietta, OK

Marietta, OK, US

On August 12, 1989, a Mooney M20K (registration N252WW) operated by Walter E. Gray, Inc. was involved in an aviation accident near Marietta, OK. Investigators recorded the probable cause as: The pilot's failure to monitor the flap position indicator during the go-around, which resulted in an improper flap configuration and subsequent loss of control. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Aircraft touched down early on runway, pilot hesitated before initiating go-around, failed to stop flaps at takeoff setting, crashed into trees beyond departure end.

What happened

The aircraft landed approximately one-third of the way down the runway. The pilot experienced discomfort with the landing but delayed the decision to execute a missed approach. During the subsequent go-around, the pilot established a climb and began retracting the flaps. However, he was unable to monitor the flap position indicator closely enough to stop the retraction at the takeoff setting.

The investigation

Following the loss of control during the climb-out, the aircraft descended into the tops of trees located on lower terrain beyond the departure end of the runway.

Findings

The pilot's failure to properly monitor the flap position during the go-around resulted in an incorrect flap configuration. This contributed to the inability to maintain sufficient lift and control authority. The delay in initiating the go-around also played a role in the outcome, as the aircraft was already committed to the landing phase with limited altitude margin.

Safety message

Pilots should promptly execute a go-around if a landing feels unsafe. During critical phases like go-arounds, maintaining situational awareness of flight control positions is essential to ensure proper configuration for climb performance.

Probable cause

The pilot's failure to monitor the flap position indicator during the go-around, which resulted in an improper flap configuration and subsequent loss of control.
