Required Actions
Inspect the material type of the lower forward corner reveal of the number 3 MEDs to determine if it is a casting. If castings, perform repetitive inspections for cracking and take corrective action if necessary. If not castings, perform a detailed inspection for a sharp edge and repetitive inspections for cracking, with corrective action if necessary. For certain airplanes, only perform a detailed inspection for a sharp edge and repetitive inspections for cracking, with corrective action if necessary. For other airplanes, perform repetitive inspections for cracking only, with corrective action if necessary. Optional replacement is allowed as an alternative to the material type inspection for certain airplanes.
