PT6A ENGINE TECHNICAL UPDATESPT6A Electrical Discharge Damage (EDD)

Issue:

If the STARTER / GENERATOR(S/G) is replaced to rectify starting /electrical generation issue, it issuspected that a electrical dischargemay have occurred though the S/Gdrive shaft.

Electrical Arcing

Starter Generator Gear

AGB input Driveshaft



No. 1 Bearing No. 1 Bearing Ball

No. 1 Bearing Thrust Race CT Blade Rub



Recommended Maintenance Actions

Ref. SIL PT6A-024

Electrical Discharge Damage (#1 Bearing)

Maintenance Manuals reflect preventive maintenance for S/G’s removed

Engine Maintenance Manual (CH 72-00-00)

Oil Filter Patch check (CH 79-20-02)

Review results within next 25 flight hours of S/G removal

Repeat Oil Filter Patch check every 100 hours for the next 700 flight hoursof S/G removal

If bearing material is found within the patch check, remove engine/gas generatormodule.


Single Engine Applications

SB 1645, Category 3, Issued Dec 2005

Visual Inspection of Fuel Pump within the next150 Flight hours.

Inspect for reddish brown residue (iron oxidedeposit) at fuel pump coupling.

Be Consistent!

15 – 20 min after engine shutdown isrecommended

If more than 30 min has passed anddipstick or sightglass indicateslow, start engine and run atground idle for 5 minutes, thenrecheck oil level


PT6A ENGINE MAINTENANCEOil Filter Inspections / Replacement

Oil Filter Inspection

Inspect initially at 100 hrs withextension to relevant airframe zoneinspection based on experience, notto exceed 200 hrs.

Oil Filter Replacement

To be accomplished every 1000 hrs


PT6A ENGINE MAINTENANCEChip Detector Inspection

Check for magnetic debris and performcontinuity check every 100 hrs withextension to relevant airframe zoneinspection based on experience, notto exceed 200 hrs.

For airframe indication systems, thecircuitry must be checked every 100hrs with extension to 400 hrsmaximum based on inspection results


PT6A ENGINE MAINTENANCEFuel Nozzle Maintenance

Why perform fuel nozzlemaintenance?

Ensure proper spray pattern

Prevent drooling, spitting andstreaking



Consequences of poor fuel nozzlemaintenance:

Cost You Money

Local overheating/burning

Improper flame propagation

Combustion liner distress

Small exit duct burning

CT Vane burning

CT Blade breakage

Can also affect your warranty claims

Compressor Turbine Vane Airfoil damage



Maintenance ManualRecommendation

200 hours for new operators andcan be escalated to 400 hrsbased on operators experience

Note: Do not double the interval,increase in steps based onexperience


PT6A ENGINE MAINTENANCEBorescope Inspection

Purpose

Allow for inspection of critical hotsection components such as the CTvane, CT blades and combustionchamber.

Also useful for inspections of the 1st

stage compressor rotor and 2nd stagepower turbine blades.

Interval

To be accomplished in conjunctionwith the scheduled fuel nozzlecleaning / testing.


PT6A ENGINE MAINTENANCEEngine Washing

Corrosion & Sulphidation attackmajor engine components

Inlet Case Corrosion

Turbine Blade Sulphidation



3 Types of Engine Washing

Compressor Desalination Wash

Turbine Desalination Wash

Performance Recovery Wash



Maintenance Manual recommendations

Compressor and CT desalination wash schedule is based on environmentand experience

Operators flying in salt laden/polluted environment should perform dailywash

After last flight of the day

Minimum water quality: drinkable water

Engine preservation also to be adapted to environment

When engine is exposed to severe environment, more stringentpreservation schedule is to be followed as defined in EMM



Best Results are obtained when:

Compressor wash is performed after last flight of day to prevent saltdeposits from doing damage overnight

Compressor Turbine wash is performed following the Compressor washsince salt and other contaminants are washed from compressor into thehot section
