Pt6-114a maintenance manual

The novel PT6A configuration has proven to be a key attribute to its success: its rearward, reverse flow inlet and forward facing turbine section providing fast maintenance turn-around through on-wing hot section refurbishment in most aircraft installations. The PT6A is a two-shaft engine with a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the propeller through an epicyclic concentric reduction gearbox.

Multi-stage axial and single-stage centrifugal compressor. Reverse flow, radial inlet with screen for FOD foreign object damage protection. Low emissions, high stability and easy starting. Cooled vanes in some models to maintain high durability. Forward-facing output for fast hot section refurbishment.

An important preventive practice such as regular fuel nozzle maintenance will minimize or prevent hot section distress. In an effort to reduce CT blade events, the engine OEM has conducted maintenance and engine operating training seminars in several continents and published numerous recommendations.

In response, we have issued some transportation-related measures and guidance. Please check if any of these measures apply to you. You may experience longer than usual wait times or partial service interruptions.

Page 25 emergency power lever Introduction The manual override function, when connected to the EPL, is intended for use during emergencies or closely monitored training only and must never be used during normal engine operation. This lever should only be used to modulate engine power to allow the pilot to continue flight to the nearest airport in the event of malfunction in the fuel control pneumatic system resulting in one of the following conditions: 1.

Page 26 scheDuleD mAintenAnce The following information is intended as an overview of maintenance practices. Chapter describes standard practices including servicing the engine oil system.

Chapter contains information on maintenance practices, including adjustment, test and cleaning. Page 27 engine inspections Chapter , Table , of the EMM contains the minimum recommendations for regular inspections of the engine. More precise intervals are used for specific components when required. Page 28 oil system inspection AnD servicing Oil Level Sightglass Some PT6A engine models are equipped with a sightglass to simplify the inspection of the engine oil level.

The sightglass has a centre green zone with red on each end. Engine operation is permitted with the oil level at any point in the green zone. Page 29 oil system inspection AnD servicing Oil Temperature and Colour High oil temperature will accelerate the accumulation of carbon particles in the oil and the deterioration of oil additives.

Oil colour will darken with usage and exposure to light. Page 30 performAnce checK Over the life of the PT6A engine, the performance charts have evolved in name, style and function. Today, a variety of charts can be found. The charts allow operators of PT6A engines to monitor the condition of their engines and the results of maintenance actions. Page 31 engine wAshing Atmospheric pollutants may contaminate the engine gas path, leading to a build up of deposits on airfoils, the initiation of corrosion, sulphidation or performance deterioration.

These effects can be alleviated with engine washing. Page 32 engine wAshing External Engine Wash Used as an effective method of tracing oil leaks, as well as removing salt and other environmental contaminants from the engine external surfaces. Wash fluid is drinking quality water, provided minimum standards are met.

Wash Schedule When operating continuously in a salt laden environment typically within 10 nautical miles from the sea and under 10, ft , it is recommended to perform compressor and compressor turbine desalination washes and Since it is generally not necessary to remove the engine from the aircraft during an HSI, the inspection procedure is both simple and fast.
