Narrative:

After touchdown, as pilot applied brakes, right landing gear shuddered and collapsed causing the airplane to tip to the right, skid and turn 180 degrees off the runway. Right propeller struck, right wing dragged on pavement. An extensive 3 1/2 month annual had recently been completed on the aircraft. After the annual, the pilots repeatedly complained to the mechanic regarding a shaking on the right side of the aircraft. Mechanic indicated his belief that the shaking was caused by a new disc brake on the right side and assured the pilots that the aircraft was safe. Mechanic declined an opportunity to ride in the aircraft to feel the shake. Initially told pilots to 'burn the new brake in' and detailed the procedure for doing so. When pilots indicated that the problem persisted, pilots brought the aircraft to the shop to assess the problem and mechanic attempted to bleed the brakes. 3 days before the incident, the aircraft was back at the mechanic's shop for a problem with the landing gear lights. Mechanic indicated problem was with nose gear and allegedly simulated approximately 15 lndgs (raising and lowering the gear). Believe incident was caused by action or inaction of mechanic.
