What was found
DURING APPROACH TO LANDING LT FLAP RETRACTED WHILE RT FLAP REMAINED EXTENDED. AN ASYMMETRICAL FLAP LANDING WAS MADE WITH MUCH DIFFICULTY BUT WITHOUT INCIDENT. INVESTIGATION REVEALED THAT A FLAP SUPPORT BRACKET PN 0523231-24 LOCATED WITHIN THE WING HAD FAILED ALLOWING THE FLAP CABLE TO LOOSE TENSION. IT APPEARS THAT PRELOAD ROM T/E SKIN POSSIBLE CAUSED THE FAILURE OF THE BRACKET.
