Hard Landing During Training Flight After Spoiler Misuse (N17901)

Indianapolis, IN, US

On July 12, 1998, a Schweizer SGS 2-33A (registration N17901) was involved in an aviation accident near Indianapolis, IN. No fatalities were reported. Investigators recorded the probable cause as: the delayed in-flight decision of the pilot in command to take control of the aircraft and the proper airspeed not obtained/maintained by the pilot in command which resulted in a stall. A factor to the accident was the runway light. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During a training flight, a CFI instructed a student to use full spoilers on base-to-final turn. The student failed to close spoilers when prompted, leading to a stall and hard landing; the aircraft struck a runway light.

Incident Overview

During a training flight, the aircraft was on a base-to-final turn at approximately 250 feet above ground level (agl) when the certified flight instructor (CFI) instructed the student to deploy full spoilers to correct the glide path to the runway. At about 100 feet agl, with full spoilers deployed, the aircraft exhibited an excessive nose-down attitude. The CFI then instructed the student to close the spoilers and raise the nose to reduce airspeed.

Sequence of Events

The student began raising the nose without closing the spoilers. The CFI took control of the aircraft and closed the spoilers completely, but the aircraft was already entering a stall. The CFI reduced the angle of attack to regain airspeed and flared close to the ground. The aircraft then landed hard, which the CFI described as 'pancaked-in, a landing hard enough to throw me into the shoulder straps and my head down so that briefly I could not see outside.' After touchdown, the aircraft drifted to the right side of the runway, and the right wing impacted a runway light before coming to a stop.
