Brief Description: Trimming Engine Cooling Fins For Clearance
As the rear edge of the cowling was trimmed, the bottom of the cowling had a net upward movement. A contact point developed at the cooling fins of the right forwardmost cylinder.
The corner of the three fins were trimmed off and then deburred. This eliminated the cooling fin obstruction.
Contact point with cooling fins developed as the rear edge of the cowling was trimmed.
