or later revisions approved by the ANAC.  After being reworked, the sockets must be re-identified from P/N S500-9140 to S500-9140-A and the electrical codes must be changed from XK0053, XK0054, XK0064 and XK0494 to XK1243, XK1242, XK1245 and XK1244, respectively.
                     b. Any socket XK0053, XK0054, XK0064 or XK0494 that is found to be damaged, replace it with new socket, P/N S500-9140-A or S500-9216, in accordance with either SB 145-30-0052 or SB 145LEG-30-0019, as applicable, or later revisions approved by the ANAC.
                Note 2:  For the purpose of this Directive, a detailed inspection (DET) is: "An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity.  Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate.  Inspection aids such as mirrors, magnifying lenses, etc., may be necessary.  Surface cleaning and elaborate access procedures may be required."
                Note 3:  ANAC AD 2007-11-04R1 refers.
Compliance:     For Requirements 1 and 3 - Within the next 2 500 hours time in service after 21 December 2007 (the effective date of ANAC AD 2007-11-04R1) or before 21 December 2009, whichever occurs first.
                For Requirements 2 and 4 - Before further flight after the Requirement 1 or 3 DET.
                This Airworthiness Directive becomes effective on 23 June 2008.
Background:     The ANAC has advised that occurrences of smoke on the flight deck originating from Pitot 1/2 and TAT 1/2 current sensor relays and their respective sockets have been reported.  The smoke was caused by poor electrical contacts between those relays and their sockets.

                This Directive requires detailed inspections of the relays and their sockets and, if necessary, replacement of the relays and sockets together with rework of some undamaged sockets.
