FAA Proposes New Airworthiness Directive for Hamilton Sundstrand Power Systems Auxiliary Power Units

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) to address two reports of uncontained failures of compressor impeller assemblies in Hamilton Sundstrand Power Systems auxiliary power units (APUs) models T-62T-46C2, T-62T-46C2A, T-62T-46C3, T-62T-46C7, and T-62T-46C7A, installed on aircraft. The proposed AD aims to prevent an uncontained APU failure and damage to the airplane by requiring removal from service of those compressor impeller assemblies at reduced service life limits.
