POST-ACCIDENT INVESTIGATION REVEALED THE ATTACHING HARDWARE CONNECTING THE LINKAGE BETWEEN THE CARBURETOR AND THE THROTTLE CONTROL WAS NOT INTACT. HARDWARE CONSISTENT WITH THE REQUIRED LINKAGE ATTACHING HARDWARE (BOLT AND CASTELLATED NUT, NO COTTER PIN) WAS FOUND IN THE ENGINE COWLING DURING POST-CRASH INVESTIGATION.

DURING AN INTERVIEW WITH THE CERTIFICATED AIRMAN THAT RETURNED THE ACFT TO SERVICE, POST CARBURETOR INSTALLATION, THE AIRMEN STATED THAT WHILE HE HAS ASSISTANCE FROM A NON-CERTIFICATED PERSON, HE HAD VISUALLY CONFIRMED THAT CARBURETOR ATTACHMENTS, INCLUDING THE COTTER PIN WERE INSTALLED/CONNECTED AS PART OF THE CARBURETOR INSTALLATION.
