Crystal River, FL, United States

On 13 May 2016, a PIPER PA-28 181 operated by ATP USA, INC. was involved in an aviation accident near Crystal River, FL. No fatalities were reported. Investigators recorded the probable cause as: The student pilot's failure to maintain directional control during the takeoff, which resulted in runway excursion and collision with a ditch. Contributing to the accident was the improper flap retraction procedure employed by the pilot during takeoff. This summary draws on records from NTSB; 12 related events involving the same aircraft type or operator are linked below.

A student pilot retracted the flaps fully at 20 feet after takeoff, causing the airplane to settle and veer off the runway left into a ditch, resulting in substantial damage.

Overview

A student pilot reported that shortly after the airplane rotated during takeoff, he noticed the flaps were extended. About 20 feet above the ground, he retracted the flaps from 25 degrees to zero degrees. Simultaneously, he encountered wind that pushed the airplane toward the ground and left of the centerline. Once the airplane settled on the ground, he attempted to correct back to the runway center but the airplane veered off the runway to the left and impacted a ditch.

Postaccident Examination

A postaccident examination revealed substantial damage to the engine mount. According to the student pilot, there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

Weather Conditions

A review of recorded data from the automated weather observation station located on the airport, revealed that about 5 minutes after the accident the wind was 280 degrees true at 6 knots with gusts to 14 knots, visibility 10 statute miles, and sky clear. The airplane landed on runway 27.

Relevant Guidance

The Federal Aviation Administration has published the Airplane Flying Handbook FAA-H-8083-3A (2004). This handbook discusses retraction of the flaps and states in part: "Depending on the airplane's altitude and airspeed, it may be wise to retract the flaps intermittently in small increments to allow time for the airplane to accelerate progressively as they are being raised. A sudden and complete retraction of the flaps could cause a loss of lift resulting in the airplane settling into the ground."
