The US Army Aviation Test Board USAAVNTBD conducted the product-improvement test of the OH-6A Helicopter Winterization Kit to determine the suitability of the helicopter and winterization kit for arctic testing. The test was conducted in a simulated Arctic environment at the Climate Laboratory, Eglin Air Force Base, Florida. Testing included 30.5 hours helicopter operating time and some firing of 7.62mm weapons. It was recommended that the design deficiencies be corrected, that further testing be accomplished in the actual arctic environment utilizing the Py-derichment fuel control, that the validity of the MCs in long-duration mission performance evaluation with crew-area temperatures between 0 F. and 10 F. be investigated, that further testing of the effects of cold weather on the sliding Teflon bearing surface be conducted, and that suitable equipment be developed to permit a reliable aircraft starting capability down to -65 F.
