## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) AIRCRAFT EXPERIENCED SUDDEN LOSS OF POWER WHILE CLIMBING OUT FROM TOUCH AND GO LANDING AT MOBILE AIRPORT (1A20). AIRCRAFT WAS SUCCESSFULLY LANDED IN OPEN DESERT APPROXIMATELY 3 N.M. S.E. OF AIRPORT. (.4) DURING CLIMB OUT THE ENGINE BEGAN SHAKING, RATTLING, AND LOSING POWER. THE FLIGHT INSTRUCTOR TOOK THE CONTROLS AND PERFORMED AN EMERGENCY OFF-AIRPORT LANDING. WHILE ON ROLLOUT THE AIRCRAFT SUSTAINED SUBSTANTIAL DAMAGE TO THE LEADING EDGES AND LOWER SURFACES OF BOTH WINGS. THE ENGINE HAD BEEN PREVIOUSLY INSPECTED IAW TCM 99-3, WHICH REQUIRED THE REMOVAL OF THE NO. 1 AND 3 CYLINDERS. UPON REASSEMBLY OF THE CYLINDERS, IT WAS NECESSARY TO REINSTALL THREE SNAP RINGS ON THE CRANKSHAFT COUNTERWEIGHTS AT THE NO. 2 AND 5 CHEEKS. AN INSPECTION OF HE NO. 5 CHEEK REVEALED THAT THESE THREE SNAP RINGS WERE NOT FULLY SEATED. THE SIGNATURES ON THE CRANKSHAFT AND COUNTERWEIGHT WERE CONSISTENT WITH A COUNTERWEIGHT STRIKING THE CRANKSHAFT. THIS CAN ONLY HAPPEN IF THE COUNTERWEIGHT PIN IS NOT IN PLACE. A REVISION TO TCM MANDATORY SERVICE BULLETIN 99-3C, PUBLISHED ON JULY 27, 1999, NOW REQUIRES THAT THE GAP BETWEEN THE SNAP RING EARS BE MEASURED TO INSURE THAT THEY ARE PROPERL                    Y SEATED DURING REASSEMBLY.
