	4. Within 25 flights after the effective date of this AD for jackscrews that accumulated more than 2200 flights, unless previously accomplished.5. From the effective date of this AD.6. Within 25 flights after the effective date of this AD for jackscrews that accumulated more than 1000 flights, unless previously accomplished, thereafter at intervals not to exceed 330 flight hours or 7 months, whichever occurs first.
	This Airworthiness Directive becomes effective on 11 May 2006.
Background:	Flap jackscrew jamming can cause an asymmetric flap situation which will result in reduced roll control of the aeroplane.
