A secondary cause of the accident was the failure of METAR to provide weather reports at 20:00, 20:15 and 20:30 when the bad weather intensified, which would have helped assist the flight to determine if it should have continued with the approach.
Unha causa secundaria do accidente foi o fallo do METAR de proporcionar informes meteorolóxicos ás 20:00, 20:15 e 20:30, cando o mal tempo se intensificou, o que podería ter axudado ao voo a determinar se debía continuar coa aproximación.
