 A. Do a check for a message on the Post Flight Report (PFR).
 If there is no message on the PFR:

 (1) With the warning message on the upper ECAM DU: "VFE........xxx":

 - do the inspection after flap/slat extension at more than the flap/slat limiting speed (VFE) (Ref. AMM TASK 05-51-13-200-001).

 (2) With the warning message on the upper ECAM DU: "VLE........280/.67":

 - do the inspection after landing gear extension at more than the geardown limiting speed (VLE). (Ref. AMM TASK 05-51-12-200-001).

 (3) With the warning message on the upper ECAM DU:
 "VMO/MMO.......350/.82":

R  (a) In the avionics compartment, on the panel 188VU, make sure that
R  the L/G DOWN VMO/MMO SELECTION switch 22FP is safetied in the position related to the aircraft last flight conditions:
 - in normal flight condition the switch 22FP must be safetied with lockwire in NORM position

 - in flight, with landing gear down condition, the switch 22FP must be at L/G DN.
