The Air Force Civil Engineer Center AFCEC tasked the Army Engineer Research and Development Center ERDC with developing a lightweight kit for proof load testing anchors used in airfield operations. The design was required to be rapidly deployable, lightweight i.e., no heavy equipment, and leave no permanent damage to the airfield. For the purposes of the project, airfield anchors were divided into three main types studsthreaded anchors, aircraft trim pad anchors, and aircraft tie-downsmooring points. Stud or threaded anchor testing can be performed expediently using a commercial testing device. Operability of the commercial device was tested at ERDC by pulling poly panel threaded rods to failure. A prototype anchor loading apparatus for trim pad anchors, the Lightweight Anchor Inspection Kit LAIK, was designed, built, and successfully tested to demonstrate operability. Trim pad anchors at Eglin AFB were proof loaded to 100 kips using the LAIK. The LAIK users manual, list of components, and design drawings are included as an appendix to the report. A tie-down anchor testing device was also designed and built. This testing device is intended to proof load aircraft tie-downsmooring points up to 70 kips. The tie-down tester makes use of the same hydraulic equipment included in the LAIK.
