Incident Overview
On 25 February 2018, a serious incident occurred involving a Boeing 737-700, registration OY-JTY, operated as a commercial air transport passenger flight under Instrument Flight Rules. The flight, en route from Aalborg, Denmark to Tenerife Sur-Reina Sofia, Spain, diverted to Las Palmas/Gran Canaria (GCLP). The aircraft sustained no damage and there were no injuries.
Flight History
Upon arrival in the Tenerife Sur-Reina Sofia area, air traffic control (ATC) instructed the flight crew to delay the approach and enter a holding pattern due to traffic congestion and weather conditions. While holding, the crew decided to divert to Las Palmas/Gran Canaria based on the remaining fuel. During the approach to Las Palmas, ATC again instructed the crew to hold. The crew calculated that the expected fuel upon landing would be below the minimum required, prompting them to declare an emergency (Mayday call). The aircraft subsequently landed with less than the minimum required fuel.
Investigation
The Danish Accident Investigation Board (AIB) was notified on 28 February 2018 and opened a preliminary safety investigation. On 6 March 2018, the AIB notified the Spanish Comisión de Investigación de Accidentes e Incidentes de Aviación Civil (CIAIAC) in accordance with ICAO Annex 13. The AIB decided not to conduct further safety investigations, closing its investigation. The CIAIAC continues its safety investigation.
