	Note 1: ANAC AD 2009-07-04 refers.
Compliance:	For Requirement 1 - Within the next 600 hours time in service (TIS) or 180 days after the effective date of the original issue of this Directive, whichever occurs first and thereafter at intervals not exceeding 600 hours TIS or 180 days, whichever occurs first.
	Note 2: If the initial inspection was accomplished in accordance with Requirement 1 of the original issue of this Directive then the timing for the repetitive inspections starts on the date when the initial inspection was completed.
	For Requirement 2.a. - Before the next flight after the Requirement 1 functional check.
	For Requirement 2.b. - Within 10 days after the Requirement 1 functional check, provided that condition a. b. and c. below are met.
	a. After each refuelling, determine the real fuel quantity in the tank with the inoperative indicator in accordance with the procedure in Requirement 1; and
	b. Both fuel flow indicators are operating properly; and
	c. Fuel used or fuel remaining functions of the totalizer are operating properly.
	For Requirement 3 - Before the next flight after the Requirement 1 functional check.
	This Amendment becomes effective on 27 August 2009.
Background:	The Brazilian Agência Nacional de Aviação Civil (ANAC) has advised it has been found that some fuel quantity probes may fail during the aeroplane life leading to an erroneous fuel quantity indication to the crew. This erroneous indication may lead to the aeroplane being operated with less fuel than indicated which may lead to an uncommanded in-flight shutdown of one or both engines due to fuel starvation.
	This amendment corrects a typographical error in the numbering of the Compliance statements.
	The original issue of this Directive became effective on 27 August 2009.
