To be undiplomatic, dialing in a crank after a prop strike or sudden stoppage as has been defined by both the manufacturers and the FAA is essentially a fools errand-at least as possible decision making criteria on the serviceability of the crank. Either may require additional inspection but neither may negate the inspections required by the FARs. DeJoris, who deals with propeller strike issues quite frequently says, "We recently had a customer with a prop strike who struck a steel stake that cut 1/4-inch of the tip off one blade of a three bladed prop.

Be especially wary if this is some form of private cash sale that has to be done right away, unless you are planning to have it torn down and rebuilt by a shop with the right inspection equipment to inspect for crank and gear damage, and be prepared for costs potentially exceeding a factory reman engine i.e. Lycoming, in their prop-strike Service Bulletin 533A, takes the approach that the safest procedure is to take the engine apart for inspection following any incident involving propeller blade damage. What you see in the pictures is what you are getting. After defining a prop strike, TCM's SB 96-11A states: "A. Propeller strike inspections.
