Exceptional Short-Term Extensions An exceptional short-term extension for aspecific Fuel System All interval may be made on one aircraft for a limited period oftime without jeopardising safety. The term 'exceptional short-term extension' isdefined as an increase in a Fuel System All interval that may be needed to cover an uncontrollable or unexpected situation. Repeated use of such extensions, either on the same aircraft oron similar aircraft inthe operators fleet, should not be used as asubstitute for good management practices. Unless noted adjacent to the task, for all Fuel System All's identified above, it has been accepted bythe Primary Certification Office (EASA) that short-term extensions upto the followi'l9 maximum values may begranted without consultation with that office. Requests forextensions in excess ofthese values must be submitted with fulljustification to the Primary Certification Office (EASA) such that approval, ifgranted, can be given prior totheir use. A. Fuel System All's controlled by Flight Hours (FH) Extensions upto 10% or500 FH (whichever is lesser) may exceptionally be granted on Fuel System All intervals quoted interms offlight hours.

This paragraph inthe Fuel Airworthiness Limitation document iswritten toconfirm to the local regulatory authority that exceptional short-term extensions of Fuel System All intervals are permissible. Approval of such extensions rests with the local authority inthe same way as it does for any other scheduled maintenance task interval extension.
