Elements of Aircraft Maintenance Reserve Development
Jackson Square Aviation, LLC Overview
Jackson Square Aviation is a global commercial aircraft lessor headquartered in San Francisco, California
2IATA Maintenance Cost Conference, Abu Dhabi, UAE October 20th, 2010Jackson Square Aviation
Current satellite offices : London, Seattle, Miami & Buenos Aires. Opening Asia office in 2010. The company has a $500 million commitment from Oaktree Capital, which has financed the management team since the mid 1990’s with a high degree of success. Jackson Square Aviation is focused on acquiring – primarily through Sale & Leaseback (SLB) :
Narrowbody & widebody Passenger & freighter

I.Annual Escalation Policies – Varies By Lessor, But Typically:1. Fixed (i.e. 3%)2. Indexed to Core Producer Price (CPI) Index3. Computed Using OEM escalation formula – weighted using labor &
material Indices (ECI – Labor & PPI - Material)
I.Airframe Heavy Structural InspectionCosts Factors
I. Airframe Age (First, Mature, & Ageing Runs)• Costs are escalated to account for
airframe ageing, which results in higher non-routine tasks.
• General “non-routine” factor escalations: 10% - 15% per phase.
II.Flight Cycles• Cost may be increased to
account for high cycle operation.

III. Scope of Work Not driven by the aircraft operation, instead Policy established by Lessor Generally Falls Under Two Structures:
Structure A - Scope of work includes reimbursement for material and routine & non-routine labor for systems, structural & zonal tasks.
Structure B - Scope of work includes reimbursement for material and routine & non-routine labor for structural & zonal tasks.

I.Airframe Heavy Structural Inspection Interval Factors
Two Types of Calendar Interval Structures:
Structure A : Calendar interval based off the OEM generic and/orsample block program.
• Example Generic Block : A320 / A330 Family : 4C/6Yr & 8C/12Yr Structural Inspection Checks @ 6 & 12 Yr Intervals,
• Example Sample Block : 737NG Family : @ 8 Yr Intervals
Structure B : Calendar interval based on timing of majority of zonal /structural tasks. Reflective of a customized maintenance program.
• Example : 737NG Family – 8, 10, & 12 Year Intervals• Example : 747-8 Family – 8 Year Intervals

I.Airframe Heavy Structural Inspection Example : A330-300 HSI Costs
Scope of work assumption: includes routine & non- routine labor for systems, structural & zonal tasks, and material.
A. First-Run Phase - New - 6 Yr• 4C/6Yr SI Cost : $1.75M• 8C/6Yr SI Cost : $1.50M
B. Mature-Run Phase - 6 Yr - 12 Yr• 4C/6Yr SI Cost : $2.01M• 8C/6Yr SI Cost : $1.50M
C. Ageing-Run Phase - > 12 Yr• 4C/6Yr SI Cost : $2.20M• 8C/6Yr SI Cost : $1.65M

4.0 – Maintenance Reserve DevelopmentIII. Auxiliary Power Unit (APU) Restoration Cost Factors• Material driven – 70% - 80% of cost is material,• Minor variance between first & mature-run costs.• Scope of work : Rework of the power section, load impeller & gearbox
modules according to OEM’s performance restoration and full gas path overhaul criteria.
Time On-Wing Factors• If new generation APU :
Use of empirical Mean-Time Between Unscheduled Removal (MTBUR) from similar in-production APU model.
• If mature APU : OEM Published Mean-Time Between Unscheduled Removal (MTBUR)
Metrics.

IV. Environment - Engines operated in dusty, sandy and/or erosive-corrosive environments are exposed to higher blade distress and thus greater performance deterioration.
Notes:• Lessors are now adjusting their reserve rates to account for
region of operation. • Generally applies to narrow-body aircraft operating within
distressed environments.

• OEM piece part escalation – currently averaging over 5% per year.
• Inclusion of Static LLPs - Although these parts are not classified to be critical they do fall under the category of parts whose failure could create a hazard to the aircraft i.e. shrouds and frames.

V. Engine Life Limited Parts (LLP) ReplacementPiece Part Life-Limit Factors
Life limits tend to range between 15,000 – 30,000 flight cycles, however LLPs can have shorter lives imposed on them by airworthiness
directives (ADs). Lessor imposed stub factor on life limits – typically:
10% for narrowbody engines 5% for widebody engines
Some manufacturers certify ultimate lives of LLPs at the time they certify an engine model. Other manufacturers certify the lives as experience is accumulated. In these scenarios, ultimate lives are reached after one or several life extensions.

Elements of Aircraft Maintenance Reserve Development
Many lessors base their costs to be reflective of costs negotiated from either a U.S. or European based MRO facility.
Consequently, their reserves rates are normally ranked as “market-based to above market-based”.Ultimately, reserves are heavily negotiated and are often “marketing” driven.
