SR: Assessing safety risks in aerodromes

JIAAC published a new Safety Recommendation (SR) included in the Safety Report of the accident of the LV-IJJ aircraft at the Aerodrome of San Juan.

It is SR 1675, addressed to the National Civil Aviation Administration (ANAC), which suggests “the conduction of a safety risk assessment in the airside of the aerodrome of San Juan,” that is to say, in the ramps, taxiways, and runway, so as to “establish mitigation measures for the identified risks.”

According to the report, the accident occurred on August 6, 2016, when the pilot of the Dinfia IAe-46 Ranquel aircraft approached the aerodrome to perform a readjustment. Once airborne, he performed two complete circuits of the runway with touch-and-go landing. During the third one, when he tried to land, the plane deflected rightwards from the runway axis and performed a runway excursion. To correct this situation, while on the safety strip, the pilot tried to take off with full drive power, and then the plane struck against a mound of earth, causing the detachment of the tail wheel.

The analysis conclusions state that the factors that contributed to the accident were the retraction of flaps during the landing roll, which decreased the distributive attention between the landing roll and the actuation of the flaps handle, and the lack of intervention by the flight instructor to modify the situation.

Furthermore, another safety deficiency was identified in relation to the aerodrome infrastructure because there was a discrepancy regarding the runway strip regulations, which affected the severity of the accident.
