## Probable cause

INCORRECT PLACEMENT OF THE RETAINING RING IN THE LEFT MAIN LANDING GEAR DOOR ACTUATOR BY THE MECHANIC RESULTING IN THE LOSS OF HYDRAULIC FLUID. THIS PREVENTED THE GEAR FROM EXTENDING RESULTING IN THE GEAR UP LANDING.

## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - landing gear,normal retraction/extension assembly - failure,total
  - fluid,hydraulic - exhaustion
  - maintenance,overhaul - improper, other maintenance personnel (cause)
- Gear not extended, landing - flare/touchdown
  - gear extension - not possible, pilot in command

## Analysis

AFTER DEPARTURE, THE PLT RAISED THE LANDING GEAR SELECTOR HANDLE BUT THE GEAR DID NOT FULLY RETRACT. HYDRAULIC FLUID AS ADDED IN AN ATTEMPT TO RETRACT THE GEAR BUT WAS UNSUCCESSFUL. THE FLT PROCEEDED TO THE DESTINATION WHERE HE ATTEMPTED TO LOWER THE GEAR BY THE EMERGENCY METHOD BUT WAS UNABLE. A GEAR UP LANDING WAS PERFORMED. EXAM OF THE ACFT REVEALED THAT THE PISTON & ROD OF THE LT MAIN LANDING GEAR DOOR ACTUATOR EXITED THE CYLINDER DUE TO INCORRECT INSTALLATON OF THE RETAINING RING. THIS ALLOWED HYDRAULIC FLUID TO LEAK, DEPLETING THE SUPPLY. THE ACTUATOR WAS OVERHAULED 6 HRS & 3 CYCLES EARLIER. 47 SERVICE DIFFICULTY REPORTS & ACCIDENT/INCIDENT REPORTS FROM 1/1/84 TO 6/26/90, INDICATED 8 FAILURES DUE TO A DISLODGED RETAINING RING.
