Compliance required as indicated. It has come to our attention that there are numerous instances wherein DC3 Series Aircraft have been approved for operation at landing and takeoff weights in excess of 25,200 pounds, in accordance with pertinent notes of Aircraft Specifications A-618 or A-669, that have main landing gear axle assemblies installed which are structurally unsatisfactory for the higher weights. The two axle assemblies involved are DACO P/N 5007396, and P/N 5007162 with P/N 5007390 torque collar. Therefore, all DC3 Series Aircraft in which either of these assemblies is installed must be operated at weights not to exceed 25,200 pounds for landing or takeoff (25,346 lbs. if deicers are installed) until satisfactory axle assemblies are installed. Note 9 of DC3 Aircraft Specification A-618 and Note 10 of DC3A Aircraft Specification A-669 contain a list of axle assemblies and the maximum weights for which each is structurally satisfactory.
