Swiss Investigation Report: FFA AS202/15-1/16M Accident at Lausanne-La Blécherette (HB-HFK)

Env. 1 km au nord ouest de l'aérodrome de Lausanne LSGL, VD, CH

On April 16, 2015, a FLUG- UND FAHRZEUGWERKE AG ALTENRHEIN (FFA) AS202/15-1/16M (registration HB-HFK) was involved in an aviation accident near Env. 1 km au nord ouest de l'aérodrome de Lausanne LSGL, VD, CH. No fatalities were reported. Investigators recorded the probable cause as: The accident was caused by an emergency landing following an initial climb in the unstable speed range (second regime) due to insufficient performance resulting from an inappropriate flap setting and a large longitudinal pitch angle. This summary draws on records from the Swiss Transportation Safety Investigation Board (STSB / SUST).

On April 16, 2015, an FFA AS202/15-1/16M (HB-HFK) crashed near Lausanne-La Blécherette during a training flight. The aircraft suffered severe damage to the left wing and landing gear after an emergency landing following an unstable initial climb.

Incident Overview

On April 16, 2015, at 09:44 local time, an FFA AS202/15-1/16M "Bravo" with registration HB-HFK crashed approximately one kilometer northwest of the Lausanne-La Blécherette aerodrome (LSGL) in the commune of Romanel, Vaud. The aircraft was operated by Air-Espace S. à r. l. and was engaged in a visual flight rules (VFR) training exercise for a private pilot license.

Flight Details and Crew

The crew consisted of a French instructor holding an EASA Commercial Pilot Licence (CPL(A)) with 1,687 total hours, and a Swiss student pilot with 26 total hours. The aircraft was powered by a Lycoming O-320-D2A engine producing 118 kW. Prior to the accident, no performance issues had been noted during training flights on April 14 and 15.

Sequence of Events

During the takeoff roll from runway 36, the student pilot lifted off at approximately 60 MPH after a ground run of about 280 meters. Immediately after leaving the ground, the aircraft exhibited an unstable flight state characterized by a nose-up attitude of 14 degrees and a right bank angle varying between 1.5 and 6.0 degrees. The airspeed remained low at 60 MPH, and the rate of climb was insufficient.

The instructor took control of the aircraft but was unable to gain altitude. At the end of the runway, the aircraft was approximately 45 meters left of the centerline, traveling at about 70 MPH ground speed at an altitude of roughly 12 meters. The instructor selected a field to the left for an emergency landing. During the descent and subsequent hard contact with the ground, the left main landing gear broke. The aircraft skidded for approximately 250 meters before the left wing collapsed and touched the ground, causing the plane to rotate 120 degrees to the left and come to rest in a cultivated field.

Damage and Injuries

Both occupants exited the aircraft unassisted and sustained no injuries. The emergency locator transmitter did not activate upon impact. The aircraft sustained severe damage to the landing gear and the left wing. Minor environmental damage included slight soil pollution and minor crop damage. No fire occurred.

Probable cause

The accident was caused by an emergency landing following an initial climb in the unstable speed range (second regime) due to insufficient performance resulting from an inappropriate flap setting and a large longitudinal pitch angle. The late assumption of control by the flight instructor could not prevent the unstable flight state. The aircraft mass, being close to the maximum allowable takeoff weight, adversely affected the accident outcome.
