Narrative:
Removed and replaced L1 window per maintenance manual. Removed shattered L1 window; replaced L1 window. Torqued to proper specifications; pressurized aircraft to 4 psi differential and then re-torqued. Aircraft was released for service at approximately XA00 pm. I understand that this aircraft had an air-return and mechanics found that the L2 window was leaking. They replaced L2 window and re-inspected torque on L1 window and found that torque was within specifications.
