Collins Aerospace has issued Service Bulletin (SB) 2-1579-32-2/Goodrich Corporation SB No. 1286, to inform Learjet 45/75 operators that some insulator assemblies supplied by the manufacturer have a groove machined at an incorrect location. 

The SB specifies that insulators on each brake (part number P/N 2-1579-2) limited to brake serial numbers D0119 throughD0123, are affected and insulators should be replaced at the next brake shop visit. 

For detailed information, Learjet 45/75 operators should obtain the above SB through the Collins Aerospace Technical Publications portal at https://customers.collinsaerospace.com.
