## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

  - landing gear,normal retraction/extension assembly - failure,total (cause)
  - maintenance - improper, other maintenance personnel (cause)

## Analysis

DURING A LNDG ROLL SUBSEQUENT TO LANDING, THE NOSE LANDING GEAR COLLAPSED. A POST-IMPACT INSPTN OF THE GEAR INDICATED THAT A BOLT (WHICH RETAINS THE RETRACT ARM TO THE BELLCRANK) HAD SHEARED. THE BOLT WAS ALSO DISCOVERED TO HAVE BEEN INSTALLED IN THE WRONG DIRECTION, NOT IN ACCORDANCE WITH THE MANUF'S MANUAL. GEAR RETRACTION TESTS DURING THE PREVIOUS ANNUAL INSPTN WERE IN NRML TOLERANCE.
