4. TT1200 with Option A There was no provision made for grounding the TT1200A Test Set to the airframe as the necessity for doing so is to our knowledge unique to the OH 58D aircraft and its installed equipment and wiring configuration Barfield has never been made aware of any other aircraft engine temperature indicating system which necessitated this grounding for correct operation The TT1200A test set can be ordered preconfigured for singular use on the OH 58D aircraft under the new Barfield P N 101 00930 OH58D This newly modified Test Set TT1200A is provided with a specific harness designed to interface it with the aircraft The only two Barfield approved Testers for the Engine Temperature Indicating System of the OH 58D airframe are the TT1200 with Option A and the new P N 101 00930 OH58D Inquiries may be emailed to gsesales barfieldinc com Nov 13 2014 Page 2 of 2 Subject Purpose Configurations Effectively Compliance Planning Conclusion SILO06 t BARFIELD SERVICE INFORMATION LETTER FOR DPS400 P N 101 01180 Pitot Static Test Set Using the Barfield DPS400 Test Set is on RVSM Certified Aircraft Regarding compliances with RVSM Barfield Inc defines compliance as meeting or exceeding the widely accepted RVSM test equipment Ps static channel accuracy specification of 0 0030 inHg To inform users how to clearly identify if their DPS400 test set configuration is in compliance to meet

7. 8D In late 2000 the US Army made Barfield aware of an issue when using the Barfield TT1200 Test Set P N 101 00920 on the OH 58D aircraft The observed error reported was that the aircraft temperature indications were unstable and subject to fluctuations Through their subsequent testing on the aircraft they made the determination that if the test set chassis was grounded to the airframe then the aircraft indicator readings were stable and accurate Nov 13 2014 Copyright 2014 Barfield Inc All Rights Reserved Page 1 of 2 Conclusion SILO05 t BARFIELD Based on these reported findings and their request for an embedded solution Barfield developed a modification for the TT1200 designated as Option A This Option consisted of a modification to the TT1200 Test Set panel connector wiring as well as the test set interface cables so that the test set chassis ground was provided by an added third clip lead to the testers cables so as to provide a ground strap to the airframe chassis The US Army subsequently procured some number of these Option A configured TT1200 testers specifically for use on the OH 58D aircraft and used them thereafter without report of any further issues The TT1200 was made obsolete upon the introduction of the TT1200A Test Set in 2003 The model TT1200A P N 101 00930 is an all new test set sharing no subassemblies with the earlier TT1200 tester P N 101 00920 The TT1200A is not a suitable substitute for the
