What is a Cost effective Engine
Management?
It is all about Management of Engines, APU
and their Accessories in a manner that
minimizes the overall Cost of
Ownership while maintaining and
improving their Reliability.
It starts before the induction of the Engine
in the fleet and
continues till its disposal or return to the
Lessor.

What it can do for You?
A well managed Powerplant* means
ensuring the following:
• Optimizing Performance on Wing
• Reduces fuel cost-
• Reduces Surprises.
• Scientific Planning and Work-scoping
• Optimizes Life on Wing
• Reduces Cost of Shop Visits
• Making Lease returns easy and Cost
effective.
• Improving resale value of the Aircraft.
* (Powerplant is Engine plus components,
plumbing and wiring etc.)

The Cost of Ignoring Powerplant
Management
 Operational:
 Rejected Takeoffs
 Flight Diversions
 Higher Fuel
Consumption.
 Reduced range/
Payloads
 Removals at
Remote Stations
 Long Delays
 Line
Maintenance:
 Unexpected
Removals
 High number of
Pilot Reported
Defects.
 Unplanned Repairs
/ Rectifications
 Operating under
muliple MELs

The Cost of Ignoring Powerplant
Management (2)
 Off Wing
Maint:
 Unplanned Shop
Visits
 High cost Failures
 Unplanned Leases
 Unscheduled Work
 Delays in
offloading to Shop
 Work on AOG
 Extra TAT
 Planning /
Financial :
 Unplanned
Expenditures due
 Leasing on AOG
 Logistics to & from
Remote stations.
 Higher than expected
Shop Invoices
 High Lease Return
Costs
 Lower Asset Value

The Fruits of Powerplant Management
Unmanaged Vs Well Managed Powerplant
Unmanaged
1. Most Engines removed
in an unplanned
manner
2. Poor engine condition
on wing & at removal.
3. Little idea about
engines’ health for
Pilots & management
4. Engines fail to deliver
power at last minute
5. High (and unpredicted)
Shop Visit Costs.
Well Managed
1. Less or no Surprises-
most engines removed as
planned.
2. Better engine condition
at removal – lower cost
3. All concerned have a fair
idea of engines’ condition
and performance on wing
through analysis of Trend
4. Timely advices for
improving reliability and
prolonging their longevity
on wing.
5. Optimized and
predictable Shop Visit
Costs.

– How? - Transition to Effective
Powerplant Engineering Management
 On Wing Maintenance:
 Establish a Powerplant Engineering Cell
 Recruit and Train your own people OR
 Outsource the activities to one or more
service providers.
 Select and implement best Engineering
ERP solutions.
 Involve PEM from the very beginning in
 evaluating and selecting the Engines
 Agreement negotiations with Lessor and
Service Providers.
 Predicting an optimized Bill Of Work.

 On Wing Maintenance Contd:
 Establish, implement and monitor
programs for
 On Wing Trend Monitoring and analysis.
 Reliability Prog
 Use trend and reliability data to
determine proper Time periods for :
 BSI/NDT inspections of critical areas
 Water wash of compressor.
 Hard and soft time limits for
components.

Transition to Effective Powerplant
Engineering Management –(3)
Off Wing Maintenance
 Properly evaluate and Select Service
Provider / MRO Shop for a long term.
 Prepare and optimize Bills of Work
 Predict and then periodically update the
expected shop visit / PFH cost.
 Physically inspect and monitor the
Engine/APU in the Shop (MRO) as
much as viable.
 Properly Scrutinize the Invoices
 Outsource any activity for which
you do not have expertise at the
moment.
