Aircraft Accident/Incident Report

Ephrata, Washington 98823
Sunday, August 2, 1998 10:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The 14-year-old Civil Air Patrol (CAP) student pilot-in-command had completed two auto-tow dual flights on the morning of the accident and was on her initial solo flight (also an auto-tow) when, according to the FAA CAP liaison officer, 'she landed with excessive airspeed, and bounced back in the air after touchdown' and then 'panicked and let go of the controls.' The FAA CAP liaison officer reported that 'witness's [sic] could hear her screaming' and that 'the left wing of the glider dropped and the nose turned to the left and dropped' and then 'the left wing hit the ground, followed by the nose.' The pilot had a total of 2 hours of flight experience all within the previous ten days to the accident, which included about 22 auto-tow flights to about 800 feet, and two aero-tow flights to approximately 3,000 feet. The FAA CAP liaison officer reported that the-14-year old student pilot may not have been mature enough for this intensive training program.

NTSB Probable Cause Narrative

The student pilot-in-command's failure to maintain control of the aircraft during the landing. Contributing factors were panic and inadequate initial training.
