fortuitous

accidental
Usage Note
Fortuito describes something that happens by chance rather than by design — not necessarily lucky, just unplanned (encuentro fortuito = 'chance encounter'). It is a false cognate for English 'fortuitous', which has gained a 'fortunate' sense in English; the Spanish word carries no positive connotation.
