Yn dilyn honiadau o afreoleidd-dra ariannol, ataliwyd arian New Sandfields Aberafan Afan (NSA Afan) ar 12 Rhagfyr 2016. Cyn atal y taliadau, roedd NSA Afan yn derbyn cyllid gan Lywodraeth Cymru fel Corff Cyflawni Arweiniol Cymunedau yn Gyntaf yng Nghlwstwr Sandfields ac Aberafan, ac fel prosiect oedd yn elwa o raglen Cymunedau am Waith a ariennir gan Gronfa Gymdeithasol Ewrop a Llywodraeth Cymru.
Following the receipt of allegations of financial irregularities, funding to New Sandfields Aberafan Afan (NSA Afan) was suspended on 12 December 2016.  Prior to the suspension of payments, NSA Afan was receiving Welsh Government funding as the Lead Delivery Body for Communities First in the Sandfields and Aberavon Cluster and as a beneficiary in the ESF and Welsh Government funded Communities for Work programme.
