2021-07-23: Cessna 172S (ZS-TBJ) — Runway 08 at Beaufort West Aerodrome, Western Cape, ZA

Runway 08 at Beaufort West Aerodrome, Western Cape, ZA

On July 23, 2021, a Cessna 172S (registration ZS-TBJ) was involved in an aviation accident near Runway 08 at Beaufort West Aerodrome, Western Cape, ZA. Investigators recorded the probable cause as: It is likely that the student pilot bounced before executing a go-around and forgot to retract the flaps that caused the airspeed not to increase past 70kts during climb; when the student pilot attempted to increase speed by lowering the nose of the aircraft,… This summary draws on records from the South African Civil Aviation Authority (SACAA) Accident and Incident Investigations Division; 8 related events involving the same aircraft type or operator are linked below.

On 23 July 2021, a Cessna 172S during solo training at Beaufort West experienced a hard landing, bounced, and the student pilot initiated a go-around without retracting flaps, leading to airspeed issues and a precautionary forced landing.

Incident Summary

On 23 July 2021 at approximately 1350Z, a student pilot conducting a solo consolidation flight in a Cessna 172S (registration ZS-TBJ) departed from Beaufort West Aerodrome (FABW) in the Western Cape Province. The pilot completed one circuit with a touch-and-go exercise on Runway 08 without incident. During the second touch-and-go, a gust of wind from the right caused a hard landing. The aircraft's nose turned left while speed was high, prompting the pilot to apply full power and rotate immediately.

Circumstances

After takeoff, while passing through 300 feet above ground level, the pilot noted the airspeed was 70 knots and the nose attitude was below the horizon. Attempting to increase speed by lowering the nose further resulted in speed decreasing to approximately 57 knots. The pilot then levelled the aircraft and checked engine gauges (rpm and oil temperature), both within limits. Believing an engine failure had occurred, the pilot declared an emergency to the Aerodrome Flight Information Service (AFIS) officer, who activated the crash alarm. Two other aircraft in the circuit were instructed to clear the path. The pilot executed two tear-drop manoeuvres—the first overshooting Runway 26, the second successfully landing on Runway 08 at 1413Z. The pilot was not injured, and the aircraft sustained no damage.

Findings

The investigation determined that the aircraft likely bounced during the hard landing before the go-around was initiated. During the climb, airspeed did not increase past 70 knots at 300 feet AGL, probably due to the flaps remaining extended. The student pilot's attempt to lower the nose to increase speed further reduced airspeed, likely because the extended flaps increased drag.

Safety Actions

The flight school briefed all student pilots on identifying engine failures and the appropriate procedures.

Probable Cause

The probable cause was that the student pilot bounced before executing a go-around and forgot to retract the flaps, which prevented airspeed from increasing past 70 knots during climb; when the pilot attempted to increase speed by lowering the nose, it led to a speed reduction.
