Part-147 or Part-145: who actually makes an aircraft engineer?

These two get mixed up constantly, even by people hiring for both. They are two different approvals, two different jobs, and the industry needs both.

Part-147 builds the engineer. It teaches:

◆ Part-66 basic training, modules and examinations
◆ Type training on specific aircraft
◆ Practical experience under supervision
◆ The certificate of recognition that feeds a Part-66 licence

Part-145 puts the engineer to work. It provides:

◆ The approved organisation where the licence becomes authority
◆ Company authorisation to certify, granted per type and per task
◆ Line and base maintenance under an approved quality system
◆ The CRS that only an authorised certifying staff member can sign

One creates the qualification. The other converts it into a signature the regulator accepts. A licence on its own releases no aircraft.

Within the Dedalus group, both sides exist. The people who train the next generation of engineers and the people who release aircraft into service work to the same standard, in the same group.

To the licensed engineers reading this: how long between passing your last module and signing your first CRS?

Nothing about an engine change is improvised.

Several tonnes of engine, suspended on certified hoists, guided onto a cradle rated for that specific engine type, and aligned to tolerances measured in millimetres.

Before the first chain takes load:

🔹 Approved removal and installation data reviewed
🔹 Bootstrap equipment and hoists within certification
🔹 Cradle and stand load rated and matched to the engine
🔹 Personnel authorised and briefed on the lift
🔹 Aircraft configured, secured and supported

At Dedalus Aviation Services, an engine change is a planned operation with a defined sequence, not a heavy lift with a deadline.

The weight is the easy part. The control is the job.

Every task on an aircraft rests on three approvals: the data, the tooling, and the materials.

The work you see on the ramp is the visible part. What makes it airworthy sits behind it.

🔹 Performed against current approved data
🔹 Tooling in calibration, with traceable records
🔹 Materials within shelf life, with batch traceability
🔹 Engines preserved, handled and transported under controlled conditions
🔹 Every step recorded before release

At DAS, this applies whether the engine stays on wing or comes off it. Same standard, from the first panel opened to the final signature.

Approved data. Approved tooling. Approved materials. If a job fails one of the three, it does not touch the aircraft.

Did you know that an aircraft keeps ageing even when it never leaves the ground?

Calendar limited tasks, life limited components and Airworthiness Directives run on the calendar, not on flight hours. A stored aircraft also carries its own preservation programme: periodic checks, engine and systems protection, and continuous record keeping.

That is why continuing airworthiness never pauses. At DAS, our CAMO keeps the maintenance programme, the records and the airworthiness status under control whether the aircraft is flying daily or sitting on the apron, so it returns to service without surprises.

There is no prompt that signs a CRS.

Software is genuinely good now. It reads fleet history in seconds, flags the component that has failed twice on the same tail, drafts the paperwork, spots the pattern nobody had time to look for.

Useful. We want more of it.

But a Certificate of Release to Service is not a data output. It is a named human with a licence number saying: this aircraft is airworthy, and I am personally accountable for that.

That signature is not admin friction to be automated away. It is the whole reason the system works.

Better tools give the engineer better information. They do not transfer the liability.

Certifying staff: what part of your job would you hand to software tomorrow?

The aircraft is not the only thing working in 40°C.

In July we posted about what extreme heat does to an aircraft on the ground. A licensed engineer asked the question underneath it: what about the people maintaining it?

Fair question, and the right one. In maintenance, asking it out loud is a safety behaviour.

August is hotter than July was. So here is the answer, properly.

Heat reaches the engineer before it reaches the aircraft:

◆ Focus: heat accelerates fatigue, and fatigue is on the Dirty Dozen for a reason
◆ Body: on a 50°C ramp you lose fluids faster than thirst warns you, and concentration goes before anything else does
◆ Hands: sweat, gloves and hot surfaces make precision work harder, from torque values to lockwire
◆ Judgment: heat plus time pressure is exactly when a shortcut starts to look reasonable

That last one is why Human Factors sits inside Part-145. Not as a poster in the crew room, but as part of how work is planned.

What that means at our line stations in peak season:

◆ Shift rotations adjusted so peak heat is rotated, not endured
◆ Hydration breaks scheduled, not left to the individual
◆ Shaded rest areas on the ramp
◆ Same checks, same standards, with the workload planned around the conditions

We said then that the aircraft does not get a summer break, and neither do we. That is true of the operation.

The aircraft does not take breaks in the heat. Our engineers do. By design.

Protecting the people is how you protect the aircraft.

To the engineers working the hottest ramps in Europe this month: what does your organisation actually do that makes a difference out there?

Every operator knows this feeling.
Compliance does not arrive one item at a time. It arrives all at once, usually in the same week.

The difference between surviving an audit season and dreading it is having a CAMO that is already three steps ahead of the geese.

CAMO and Part-145 under one roof. That is the whole point.

An Airworthiness Directive is not a suggestion.

A Service Bulletin usually is, until an authority decides otherwise.

A Modification is neither. It starts with you.

Three documents, three completely different obligations.
Telling them
apart, on every aircraft, every time, is where continuing airworthiness
actually happens.

Our Dedalus CAMO team assesses each one against your fleet: applicability,
impact on safety, cost and downtime, scheduling of the corrective
action, and a record that holds up under audit.

For large and commercially operated aircraft this is not just good
practice. M.A.301(7) requires an embodiment policy for every
non-mandatory modification or inspection not covered by an AD, with
the decision recorded and justified.

If you want a second pair of eyes on how your ADs, SBs and Mods are
being managed, send us a message.

An aircraft can legally fly with an inoperative item. That is not a shortcut. That is the MEL.

The Minimum Equipment List defines which items may be unserviceable, under which conditions, and for how long before the aircraft must be repaired.

Get it right and you protect the schedule without touching safety. Get it wrong and you have an undocumented defect on a flying aircraft.

For operators, MEL discipline is where continuing airworthiness is either respected or quietly eroded.
