What was found
(JRUR) A CRACK WAS DISCOVERED IN THE FIREWALL FWD DOUBLER (PN 0753600-24). THE CRACK WAS LOCATED BEHIND THE COWL EXIT RAMP- RT (PN 0752732-2). THE CRACK WAS 2-3 INCHES LONG. THIS AREA IS VERY DIFFICULT TO INSPECT ON A P1 (50 HR) WITH THE LOWER COWLING INSTALLED. IT IS STILL DIFFICULT TO INSPECT WITH THE LOWER COWLING REMOVED ON A P2 (100HR) OR P3 (ANNUAL), BUT IT IS ACCESSIBLE. THERE WAS SUBSTANTIAL DIRT AND OIL BUILD UP IN THE AREA BEHIND THE COWL EXIT RAMP MAKING THE AREA HARDER TO INSPECT.
