What was found
AFTER FINDING THE LT AFT ELEVATOR BELLCRANK PN 265-5221313 FS457 CRACKED AT LOWER BEARING BOSS AREA ON A DIFFERENT NA 265-65 AIRCRAFT WE PERFORMED INSPECTIONS ON 5 EA. ADDITIONAL NA 265-65 AIRCRAFT THAT WERE IN HOUSE. THIS INSPECTION UNCOVERED A CRACKED BELLCRANK AT THE LOCATION ON THIS AIRCRAFT. RECOMMEND OPERATORS OF NA 265-65 MODEL AIRCRAFT PERFORM A CLOSE VISUAL OR EDDY CURRENT INSPECTION OF THE LOWER BEARING BOSS AREA OF LT BELLCRANK PN 265-5221313 AS SOON AS POSSIBLE. POSSIBLE CAUSE HAS YET TO BE DETERMINED BUT THE HIGH CABLE TENSION AND THE BIAS LOADING OF THE ELEVATOR CABLES MAY BE A CONTRIBUTING FACTOR OR THE POSSIBLE STAKING OF THE BEARING COULD WEAKEN THE AREA AFFECTED. MFG HAS BEEN NOTIFIED.
