There are also a number of possible explanations for FAP's low AFH: concern over the aging of equipment, scarcity of spare parts – especially for the older aircraft – difficulties with worn airframes and the scarcity of fuel are all contributing factors. It is very likely however that some 'elite' pilots and regiments such as those based in Talara AFB and La Joya AFB received considerably more flying hours. Especially since those regiments until today are equipped with modern aircraft and tasked with homeland defence.
