AS THE AIRPLANE REACHED THE END OF THE 600-FT STRIP, THE PILOT APPLIED THE SECOND NOTCH OF FLAPS. THE AIRPLANE BECAME AIRBORNE FOR ABOUT 20 FT, AND THEN SETTLED INTO BRUSH. THE PASSENGER REPORTED THAT 'MY IMPRESSION IS THAT WE LACKED OR LOST ADEQUATE POWER TO MAINTAIN FLIGHT...' ANOTHER COMPANY PA-18 AT SITE HAD NO DIFFICULTY IN FERRYING EVERYONE FROM THE SITE. EXAMINATION OF THE ENGINE SHOWED THAT AN EXHAUST CAM LOBE WAS 30-40% WORN, AND THE ASSOCIATED CAM FOLLOWER WAS WORN AND DISH SHAPED. THE DEPTH OF THE WORN AREAS EXCEEDED THE DEPTH OF THE NITRATED SURFACE. ACCORDING TO THE DIR OF MAINT, A 50-HR INSPECTION WAS PERFORMED PREVIOUS TO THIS FLIGHT AND METAL PARTICLES WERE FOUND IN THE OIL SCREEN.
