The product improvement test of the U-8F Airplane (ECP-BEA-L23-138) was conducted by the US Army Aviation Test Board (USAAVNTBD) during September and October 1964. Deicing tests were conducted under artificially-induced ice conditions. Instrumented tests were conducted at the Beech Aircraft Company by Beech personnel. It was found that the ECP-BEA-L23-138 Retrofit Kit was capable of anti-icing and deicing the windshield and propellers of the U-8F airplane; the test system was functionally suitable, the generating system was capable of providing 300 amperes per generator; components of the test system were compatible with each other and with the U-8F a special tool was required to remove the rearmost generator mounting nuts; noise suppression devices did not reduce noise level in radio compass to an acceptable level; and maximum temperature in the avionic compartment or radome was 149.8 F. at 95 F. ambient temperature. It was recommended that the shortcomings be corrected; propeller deicing time be modified to provide 80-second cycling; and the special tool required to remove rearmost generator mounting bolts be procured with the retrofit kits.
