32 32 Nacelles Oil Cooler Inlet Generator Cooling Air Duct / Shutoff Valve …also used to cool eng mounts

33 33 Nacelles Forward Spinner Aft Spinner Cuff Island Check for proper blade angle (should see three holes)

34 34 Main Mount Wheel Well General Items: -Chocks -Grounding strap -Tires

35 35 Counter Measures (If Installed) should see 1 pin per set of buckets Mechanical Down Lock Linkage Bungee Springs – help with freefall extension in flight Brake Fuse 30 cubic inches of fluid actuates shut off Fire Shield Normal Brake Lines Emergency Brake Line Look For: Uneven Tread Wear Max Tread Wear: When tread pattern is worn to the bottom of the tread groove Flat Spotting: due to prolonged standing Sidewall conditions: Look for cracks, cuts, abrasions, bulges, gouges, cord plies Enough tread for bounce flight? Lower drag strut

36 36 Main Mount Wheel Well Shuttle Valve Brake Pucks (1,2,3 rule) 1. No ONE flush 2. No 2 side by side not fluxing 3. No THREE total not fluxing with brake actuation.
