AFTER COMPLETING THE BEFORE TAKEOFF CHECKLIST, RUNUP, AND RECEIVING TAKEOFF CLEARANCE, MISS KRUEGER AND MR. WALKER DEPARTED RUNWAY 29. THEY APPLIED FULL POWER FOR TAKEOFF AND DURING CLIMBOUT, AROUND 400 FEET, THE AIRCRAFT BEGAN TO SHAKE AND A REDUCTION IN POWER WAS FELT. AT THIS POINT, MR. WALKER TOOK CONTROL OF THE AIRCRAFT WHILE MISS KRUEGER REFERENCED THE NECESSARY CHECKLISTS. MR. WALKER DECLARED AN EMERGENCY AND CLEARANCE WAS GIVEN TO LAND ON EITHER RUNWAY 11 OR RUNWAY 29. THEY BEGAN TO MAKE A RIGHT HAND TURN AND LANDED SAFELY ON RUNWAY 11. ATC ASKED IF THEY NEEDED FURTHER ASSISTANCE WHICH THEY DECLINED. THEY EXITED THE RUNWAY AND TAXIED BACK TO THE TIE-DOWN. UPON INSPECTION OF AIRCRAFT N9389L, IT APPEARS THAT THE NUMBER THREE CYLINDER EXHAUST VALVE MAY HAVE BEEN DISLODGED. IT APPEARS THAT THE PUSH ROD TUBE MAY HAVE BEEN DISLODGED AS WELL.

Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
