0:09 So let's begin by defining what we mean
0:11 by spare parts in the context of
0:14 aviation. Spare parts are basically
0:15 replacement items used during the
0:17 maintenance, repair or overhaul of
0:28 Airlines actually manage tens of
0:30 thousands of part numbers from tiny
0:32 screws all the way up to major landing gear
0:41 assemblies. There are a few different
0:44 types of spare parts. Consumables are
0:47 used just once, like filters or seals.
0:49 Expendables are lowcost items that
0:51 aren't repaired, such as O-rings.
0:53 Rotables are high value and repairable,
0:56 for example, avionics or actuators. And
0:57 then you have repables which aren't
1:00 rotables but can still be repaired like
1:02 certain brackets or [Music]
1:11 panels. For example, a Q400 aircraft
1:13 nose wheel tire is classified as a
1:15 repairable while the main gear strut is
1:25 So forecasting is really the foundation
1:28 of spare parts management. If you get
1:29 this wrong, well, you either end up
1:32 overstocking or worse, you go AOG,
1:34 aircraft on [Music]
1:42 ground, right, let's talk about the
1:45 types of forecasting. There's historical
1:47 usage analysis which looks at how parts
1:49 have been used in the past. Then failure
1:52 rate modeling often called MTBR or
1:55 meanantime between unscheduled removals.
1:57 We also have predictive analytics using
1:59 AI which is becoming more common these
2:02 days and of course scheduled maintenance
2:04 forecasts like you know those known Cch check
2:14 requirements. Now moving on to planning
2:17 methods, we have ABC classification,
2:19 which sorts parts by their criticality
2:21 and value. There's also safety stock
2:23 modeling, which helps ensure you don't
2:26 run out of essentials. And finally,
2:28 cannibalization modeling, which is
2:29 influenced by things like scheduled aircraft
2:31 aircraft [Music]
2:37 [Music]
2:39 retirements. So, let me give you an
2:42 example. The A330 oxygen masks may have
2:45 shown low usage historically, but if a
2:47 new airworthiness directive changes the
2:49 replacement cycles, then forecasting has
2:54 [Applause] [Music]
2:57 [Music]
2:59 immediately. There are several tools out
3:02 there like Amos, Tracks, Ramco, and SAPM
3:04 which all have built-in forecasting and
3:14 It all comes down to deciding how much
3:16 to hold, where to hold it, and of
3:19 course, who actually owns [Music]
3:27 it. So, let's talk about stocking
3:29 models. There's the choice between
3:31 centralized and decentralized storage,
3:33 which can really impact how quickly
3:35 parts are available. Forward stocking at
3:37 main airports is a common approach,
3:39 especially for airlines that want to
3:41 keep things moving smoothly. And you
3:43 know, hub and spoke models are often
3:45 used by global airlines to make sure
3:47 parts are where they need to be when
3:49 they need to be [Music]
3:57 there. Now, moving on to inventory optimization.
3:59 optimization.
4:00 One key aspect is service level
4:03 targeting like aiming for a 95% fill
4:06 rate for example. It's always a
4:08 balancing act between carrying cost and
4:10 stockout cost. Plus managing life
4:14 limited parts or LLPs and dealing with
4:16 obsolescence is absolutely crucial to
4:19 keep everything running efficiently. [Music]
4:27 For instance, Emirates maintains a
4:29 forward stocking location in London
4:31 Heathro to ensure quick access to wheels
4:34 and brakes. This setup really helps
4:35 reduce flight delays that could be
4:47 unavailable. So, let's talk about shelf
4:49 life management. Many aviation parts
4:51 actually have specific shelf lives.
4:54 Think items like life vests, fire
4:56 extinguishers, or even adhesives. This
4:58 means, you know, managing these parts
5:00 really requires a first in first out
5:02 inventory system and of course frequent
5:05 audits to make sure nothing expires [Music]
5:13 unexpectedly. When it comes to vendor
5:16 selection, there are several options.
5:18 You have OEMs such as Honeywell or
5:21 Saffron. Then there are PMA or parts
5:23 manufacturer approval sources. And
5:25 finally distributors like AVL and
5:27 SATire. Each plays a different role in
5:37 Honestly, there are a few different
5:39 contract types used in aviation parts
5:42 procurement. These include spot buys,
5:45 long-term agreements, often called LTAs,
5:47 power by the hour arrangements, and
5:49 consignment agreements. Each contract
5:52 type really has its own set of benefits and
5:53 and [Music]
5:59 [Music]
6:02 considerations. So, for example, let's
6:04 say an airline signs a consignment
6:06 agreement with Collins Aerospace. In
6:08 this arrangement, the parts actually
6:10 remain owned by Collins until they're
6:12 used, which, you know, really helps
6:21 [Music]
6:23 airline. When it comes to negotiation
6:25 considerations, there are a few key
6:28 things to keep in mind. Lead times,
6:29 warranty and returns, pricing
6:31 escalators, and of course, compliance
6:34 with ISA or FAA certifications. All of
6:37 these can really impact the [Music]
6:45 agreement. Here's a quick tip. Always,
6:47 and I mean always, verify traceability
6:51 and certification like FAA 8130-3 or ISA
6:53 form 1. This is super important to avoid
7:03 [Music]
7:05 So in today's global airline industry,
7:07 collaboration is [Music]
7:15 key. Right, let's talk about the types
7:18 of pooling. There are OEM pools like
7:20 Airbus FHS and Boeing Gold Care. Then
7:22 you've got independent pools such as
7:25 spar liners, AJW and Lufanza Technic.
7:27 And finally there are inter aairine
7:28 pools which operate through the
7:38 [Music]
7:41 IATP. For example, let's say a Thai
7:43 based airline joins IATP and suddenly
7:46 has access to over 10,000 roles all
7:49 around the world. If say an actuator
7:51 fails in Tokyo, another airline in the
7:55 pool can supply it the very same day. [Music]
8:00 [Music]
8:02 exchange programs. Well, they allow
8:04 airlines to swap identical roles and
8:07 then settle repair costs later. This
8:08 approach really supports fleet
8:10 commonality, making operations smoother
8:12 for everyone [Music]
8:20 involved. Airline parts logistics is not
8:22 just shipping, it's aviation grade
8:24 logistics. And honestly, that means a
8:27 whole new level of precision and [Music]
8:36 reliability. AOG logistics or aircraft
8:37 on ground logistics is all about
8:39 providing a roundthe-clock response when
8:42 an aircraft is grounded. This often
8:44 involves using couriers, charter
8:45 flights, and express freight to get
8:47 planes back in the air as quickly as possible.
8:58 So, here's an example. Imagine an A380
8:59 is grounded in Sydney because of a
9:02 failed avionics module. DHL manages to
9:04 rush a replacement unit all the way from
9:06 Frankfurt and they do it within just 18
9:09 hours using Priority Air [Music]
9:18 Cargo. Now, routine logistics are a bit
9:20 different. These involve scheduled
9:22 shipments that are based on maintenance
9:24 planning. Often bonded warehouses are
9:26 used to defer duties, which is pretty
9:28 clever. And you know, special packaging
9:30 and temperature control are needed for
9:32 sensitive items like avionics or adhesives.
9:42 Major logistics partners in this space
9:45 include DHL Aviation, Quain Plus, Nagel,
9:57 solutions. All right, so let's talk
10:00 about some key metrics. First up,
10:01 there's fill rate, which is the
10:03 percentage of requests that are actually
10:06 fulfilled. Then we have stockout rate
10:08 which tracks how often items are out of
10:10 stock. Inventory turnover is another
10:12 important one. It measures how quickly
10:15 inventory is being used or sold. There's
10:18 also AOG response time and finally
10:21 repair turnaround time often called TT.
10:23 These metrics, you know, really help us
10:25 understand performance and efficiency in
10:36 So for example, a top tier airline aims
10:37 for an aircraft on ground part dispatch
10:40 within 2 hours of notification and um
10:42 they track on-time logistics performance every
10:51 month. Compliance is absolutely
10:53 critical. All parts must meet
10:55 airworthiness and traceability
10:58 requirements. Regulators like the FAA,
11:00 ESAR and local civil aviation
11:02 authorities can, you know, audit stores
11:05 and documentation at any [Music]
11:12 time. In this module, we explored the
11:15 backbone of aircraft availability, spare
11:17 parts management. From forecasting and
11:20 sourcing to pooling and logistics, every
11:22 single decision impacts aircraft
11:25 readiness, cost, and compliance. [Music]
11:33 Strong coordination between planning,
11:35 procurement, engineering, and logistics
11:38 is honestly essential. With smart
11:40 systems and strategy, supply chains can
11:42 transform from a reactive model into a
