Any components or structure that are lifed on landing cycles may incur a penalty factor on that life for every overweight cycle e.g PF of 2 would mean a cycle would be recorded as two cycles. It maybe a case that aircraft are being temporarily grounded while Tech Records are calculating how many overweight cycles have occurred, what penalty factors apply and amending component usage lives accordingly. It might not just be landing cycles. It could apply to flying hours also.The PF will be stipulated in manufacturer airworthiness requirements.
