Airworthiness Directive · Amendment 39-10565 · AlliedSignal Inc. Model TPE331 Series Turboprop Engines
AlliedSignal Inc. Model TPE331 Series Turboprop Engines
AlliedSignal Inc. (formerly Allied-Signal Aerospace Company, Garrett Engine Division and Garrett Turbine Engine Co.) Model TPE331-8, -10, -11 and -12 series turboprop engines with fuel manifold, Part Number (P/N) 3102469-1 or -2, repaired by Hoses Unlimited, Inc. prior to November 20, 1995. These engines are installed on but not limited to Ayres S2R-G10; Cessna Model 441; Construcciones Aeronauticas, S.A. (CASA) C-212 series; Dornier 228 series; Fairchild SA226 and SA227 series; Jetstream 3101 and 3201 series; Mitsubishi MU-2B series (MU-2 series); and Twin Commander Aircraft Corp. Models 695 and 695A aircraft.
This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Inc. Model TPE331 series turboprop engines, that requires removal of suspect fuel manifold assemblies and replacement with serviceable assemblies. This amendment is prompted by an FAA investigation into Hoses Unlimited's repairs of TPE331 fuel manifolds, which were not approved by the FAA. The actions specified by this AD are intended to prevent fuel leakage at the fuel manifold fittings, resulting in fuel spraying on hot turbine components, which could result in an engine fire.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
