Flight details and accident description On 1 December 2015 at 12:05 local time, a Socata TB20 registered F-GMQF, operated by a flight school, was conducting a general aviation flight. The pilot and an instructor were aboard. The aircraft departed Montpellier Méditerranée for a proficiency maintenance flight and proceeded to Nîmes Garons, where it performed a reconnaissance circuit. The crew then carried out a series of training exercises involving reduced power and two touch-and-go landings, first with flaps set to 10° and then to 0°. As the wind increased, the instructor proposed two additional reduced-power exercises. During the first, the pilot was asked to extend the flaps to 10° and the landing gear at the start of the exercise. During the second, the pilot extended the flaps to 10° and identified and announced the landing-gear-not-extended warning, but did not extend the gear because he was listening to the instructor’s explanations on trajectory and speed management in the wind. The pilot then focused on the trajectory and omitted the pre-landing checklist on final approach. When the aircraft touched down, the pilot and instructor realized the gear had not been extended. The aircraft was heavily damaged.

Probable cause

The accident was due to the failure to extend the landing gear. During the training exercise, the instructor set the power control to idle, which triggered the landing-gear-not-extended warning. The pilot identified the warning but deferred the actions normally associated with it. Habituation during the exercise may have led both the pilot and instructor to disregard the warning and forget the related actions. The warning and the pre-landing checklist are safety barriers; the training scenario weakened this barrier, requiring the instructor to increase supervision to maintain an equivalent safety level.
