Description

The Fiberglass Frangible Approach Mast was developed by the Federal Aviation Administration as a Low Impact Resistant (L.I.R.) support structure for high intensity (ALSF2) approach systems from 6 ft. to 128 ft. The essential function is to provide frangible support for equipment installed in the clear zone. In 1979 Jaquith Industries received a government contract as the lead manufacturer to develop the LIR Fiberglass Frangible Mast. Since then, Jaquith has expanded the role of the LIR Mast to include a variety of other applications. LIR is defined as a break-away mast for use in structures that support airport approach lighting & support systems. The LIR design will withstand 100 mph winds without ice and 75 mph winds with a 1/2 inch radial ice load. Yet, should an aircraft slip below the glide slope and impact a support structure, the structure breaks into pieces without catastrophic damage to the wing support.
