## Discrepancy

LEFT MLG INBD DOOR CAME OPEN AFTER TAKEOFF, REPORTED BY CONTROL TOWER.  LANDING MADE WITHOUT INCIDENT.  FND GEAR RETRACT IDLER BELLCRANK BROKEN 2 INCHES FROM END OF ARM THAT RUNS GEAR DOOR EXTEND/RETRACT LINKAGE.  BELLCRANK SHOWS EVIDENCE OF HAVING BEEN CRACKED ONE-THIRD OF ITS THICKNESS FOR SOME TIME, MONTHS PERHAPS.  THE RT BELLCRANK ON ACFT CRACKED AND LATER BROKE IN SIMILAR FASHION ABOUT 1 YEAR PRIOR.  SUSPECT PRIOR IMPROPER RIGGING AND TOO MUCH GEAR DOOR TENSION WHEN GEAR DOWN.  SUGGEST CLOSE INSPECTION AS THIS BELLCRANK IS IN SUCH A LOCATION THAT IT IS DIFFICULT TO INSPECT THOROUGHLY.  SUGGEST CLOSE ADHERANCE TO CESSNA RIGGING PROCEDURES.  CRACK BEGAN AT TOP.
