## Discrepancy

B100-06 RUBBER DRIVE COUPLING BETWEEN LANDING GEAR MOTOR AND TRANSMISSION, ABSORBS SHOCK WHEN LANDING GEAR REACHES ITS LIIT, THIS IS THE ONLY CONNECTION BETWEEN TRANSMISSION AND GEAR LINKAGE, WHEN THIS PART FAILED, YOU CANNOT PERFORM ANY GEAR EXTENSION, ELECTRICALLY OR MECHANICALLY.
