How to Prevent Events & Unplanned Removals


WHY TORQUE NOT TEMP?

Do you set your power to torque per POH?



ECTM ANALYSIS

How

Identify “ECTM experts” - Allows for continuity in analysis

Who

Within your company (Training available at Flight Safety)

Use of Designated Analysis Center (DAC) - Subscription

Review Data

With WebECTM

Online trend monitoring and review

Benefits

Enhance communication between maintenance & flight ops

Timely interventions upon trend indications



PT6A ENGINE MAINTENANCEBorescope Inspection

Purpose

Allow for inspection of critical hot

section components such as the CT

vane, CT blades and combustion

chamber.

Also useful for inspections of the 1st

stage compressor rotor and 2nd stage

power turbine blades.

Interval

To be accomplished in conjunction

with the scheduled fuel nozzle

cleaning / testing.



Description• Identify “borescope specialists”

• Provide specialized training and foster expertise

• Allows for consistency in method and continuity in analysis of results

• Reports of borescope inspections should be sent to the borescope specialist for analysis and adjustment of maintenance plan

• Monitor condition of gas path components

Benefits• Detect premature hot section distress

• Repair vs un-repairable

PT6A ENGINE MAINTENANCEBorescope Inspection



Description

• Borescope unit with high resolution and digital picture capability

• Monitor progress of deterioration

• Archive and communicate results

Benefits

• Proper diagnosis compared to premature engine removal due to incorrect interpretation

• New revision of SIL NO. GEN- PT6-029 to be issued for equipment recommendation updates

PT6A ENGINE MAINTENANCEBorescope Inspection - Equipment


Maintenance Best Practices


FOD & EROSION PREVENTIONGeneral

Use inertial separator during taxi operation and icing conditions

Check that the tarmac is clean during walk-around

Avoid dropping safety wire or rivets in the air inlet plenum area

Install inlet / exhaust covers when aircraft not in use

Do not use reverse thrust at low ground speed

What damages the prop may damage the compressor

Damage example

1st stage Compressor



FOD & EROSION PREVENTIONInertial Particles Separator Operation


GROUND FLIGHT

Avoid starts with separator deployed

Only open separator in High Idle

Watch ITT closely during deployment

Reduce power by 10% before deployment

Allow for deployment time before entering

icing conditions

Watch ITT closely during deployment


FOD & EROSION PREVENTIONFirst Stage rotor icing damage

First stage blade bending is consistent with an

impact from a soft body that could be related to

formation of ice or other particles

Preventive Field Actions

Troubleshooting chart improvement made to add

unusual compressor high pitch noise to trigger

maintenance action

Add a periodic inspection (annual) for visual

borescope inspection on First Stage Rotor

Export Classification: (Canadian ECL:

N/A, US P-ECCN 9E991)

First Stage rotor icing damage

Q: When should the inertial separator be

activated?

A: Check the Pilot Operating Handbook

What’s the root cause of observed damage?

Erosion due to sand / dirt ingested


Inadvertent Cutoff & Relights and POHIssue

During landing roll engine flame came-out

from the exhaust pipe

Investigation

FCU and Fuel Flow Divider tested and

found acceptable

Conclusion

Hot section damage is consistent with an

overtemperature at a low Ng speed

Flame in exhaust and melted CT blade

tips associated to overfuelling

Export Classification: (Canadian ECL: N/A, US

P-ECCN 9E991)

Shroud segments covered with metal

splatter

Engine overtemps


Why do fuel nozzle maintenance?

EMM Recommendation

200 hours for new operators and

can be escalated to 400 hrs

based on operators experience

Note: Do not double the interval,

increase in steps based on

experience

PROPELLER STRIKE OR STOPPAGE

MM Chapter 72-00-00 Unscheduled inspection

For propeller strike causing minor blade damage (not structural, eg. delamination,

indentation, blade tip bent slightly, etc.) with engine at or below FLIGHT-IDLE power

or while engine was shut down, do the following:

• Turn propeller by hand, if no unusual noise from Power Section, run engine

at 80% TQ for 10 minutes, check chip detector, oil filter. Etc...

For propeller sudden stoppage, propeller strike causing blade structural damage

(eg. bent blade, or blade tip missing or bent over 1 in. (over 5 in. for composite

blade)), propeller strike on a power line, or propeller strike at power above FLIGHT-

IDLE (Ng above 82 %), do the following

• Engine is to be removed and sent to a shop for Light Overhaul. Ect..

If you need help to evaluate the propeller condition with respect to the

workscope to be applied, refer to EMM, then call CFirst or P&WC FSR
