    07/17/09 Turbofan Engine Malfunction Recognition and Response Final Report Foreword This document summarizes the work done to develop generic text and video training material on the recognition and appropriate response to turbofan engine malfunctions, and to develop a simulator upgrade package improving the realism of engine malfunction simulation. This work was undertaken as a follow-on to the AIA/AECMA report on Propulsion System Malfunction Plus Inappropriate Crew Response (PSM+ICR), published in 1998, and implements some of the recommendations made in the PSM+ICR report. The material developed is closely based upon the PSM+ICR recommendations. The work was sponsored and co-chaired by the ATA and FAA. The organizations involved in preparation and review of the material included regulatory authorities, accident investigation authorities, pilot associations, airline associations, airline operators, training companies and airplane and engine manufacturers. The FAA is publishing the text and video material, and will make the simulator upgrade package available to interested parties. Reproduction and adaptation of the text and video material to meet the needs of individual operators is anticipated and encouraged.

FAULK Conducted lAW Air Force Instruction 51-503 EXECUTfVES~Y AIRCRAFT ACCIDENT INVESTIGATION BOARD F-16C+, SN 87-0242 TRUAX FIELD, WISCONSIN 7JUNE2011 On 7 June 2011, at 1316 local time, an F-16C+, serial number 87-0242, impacted the ground approximately 57 nautical miles northwest of Truax Field, Wisconsin. The Mishap Aircraft (MA) and Mishap Pilot {MP), assigned to the 176th Fighter Squadron, 115th Fighter Wing, Truax Field, Wisconsin, were participating in a training mission when the MA experienced a sudden loss of thrust approximately one hour and twenty-three minutes after takeoff. The MP was unable to achieve a successful engine restart. The MP ejected safely and sustained only minor scratches and bruises. The MA impacted near an unoccupied private residence and both were completely destroyed. There were no civilian injuries. The MA was valued at $25,691,100.30. The mishap mission was briefed as a continuation training basic fighter maneuver mission which involved simulated air-to-air "dogfights" between the MP and the mishap wingman, each in their own F -16 aircraft. As the mishap flight prepared to return to base, the MA experienced a sudden loss of thrust. The MP had cockpit indications of an engine failure and immediately began a turn to the nearest suitable runway while simultaneously initiating air start procedures to recover the engine. The MP jettisoned his empty external fuel tanks to reduce drag once clear of a populated area below the MA.

  • 2.10. ENGINES the Airplane Is Powered by Two Counter-Rotating Pratt & Whitney PT6A-66 Turboprop Engines, Each Flat Rated to 850 SHP
    PILOT’S OPERATING HANDBOOK P.180 AVANTI II DESCRIPTION AND OPERATION ENGINES 2.10. ENGINES The airplane is powered by two counter-rotating Pratt & Whitney PT6A-66 turboprop engines, each flat rated to 850 SHP. The rated power can be maintained during cruise to approximately 25,000 feet on a standard day. Inlet air enters the engine through an annular plenum chamber, formed by the compressor inlet case. The four-stage axial and single-stage centrifugal compressor is driven by a single-stage turbine. Downstream the compressor the air is routed through diffuser tubes to the combustion chamber liner. The flow of air changes direction of 180 degrees as it enters and mixes with fuel. The fuel/air mixture is ignited by two spark igniters, which protrude into the combustion chamber, and the resultant expanding gases are directed to the compressor turbine and then to the power turbine. The compressor and power turbines are located in the approximate center of the engine with their respective shafts extending in opposite directions. The exhaust gas from the power turbine is collected and ducted in the bifurcated exhaust duct and directed to atmosphere via twin opposed exhaust stubs. The fuel supplied to the engine from the airplane fuel system is routed through an oil-to-fuel heater to an engine-driven fuel pump where it is further pressurized. The fuel pump delivers the fuel to a fuel control unit, which determines the correct fuel schedule for engine steady state operation, both with and without power augmentation and acceleration. A flow divider supplies the metered fuel flow to the primary or to both primary and secondary fuel manifolds as required.

Of the 44 persons aboard, 10 were injured seriously. The aircraft was damaged substantially during the crash sequence and was destroyed by ground fire. The National Transportation Safety Board determines that the probable cause of the accident was the unwanted autofeather of the left propeller just after takeoff and an encounter with turbulence and downdrafts--a combination which exceeded the aircraft's singleengine climb capability which had been degraded by the high density-altitude and a turn to avoid an obstacle in the flightpath.
