Heads up #41
Flap Detent Mount Bracket Reinforcement
We have had one Panther LS powered by a Lycoming 0-320 develop a miniscule crack along the weld at the top of the flap detent mount.
Action Required
Note: Later airframes have a brace tube installed to stiffen the detent plate mount bracket (see photo below). These airframes do not require any action other than normal preflight and condition inspections
Inspect the area identified in photos below for signs of cracks.
SPA LLC recommends installing a flap detent bracket reinforcement kit per drawings and instructions in kit.
Even if no crack is detected SPA LLC feels that the probability of an eventual crack is high enough to warrant a preventative measure.
