Compliance required as indicated.

Several incidents have occurred of failure of the main landing gear retracting strut and attaching fittings. Therefore, the following must be accomplished within 50 hours' time in service after the effective date of this AD, and at intervals thereafter, not to exceed 50 hours' time in service from the last inspection.

  (a) Inspect the entire main landing gear retracting strut (Bellanca P/N 7577 L/R), and the rear spar main landing gear fitting (Bellanca P/N 7560 L/R) for cracks using a dye penetrant and a 10-power magnifying glass, or an FAA approved equivalent inspection. Give particular attention to all welds, especially at the connecting link trunnion housing, and tube intersections. Prior to inspection, remove all grease and dirt from all surfaces of the upper and lower struts connected by the connecting link.(b) If cracks are found, repair that part in accordance with an FAA approved repair, or replace with a new part of the same part number, or an FAA approved equivalent before further flight.
