The Problem Isn't You. It's How It Was Explained to You.

You're on the pad before the first lift and the check pilot points at the cargo hook: walk me through it, piece by piece, and tell me how it releases.

You know you read it. But the manual gives you the hook in paragraphs: load beam, keeper, solenoid, manual release, all in one block of text. Under the rotor, a paragraph doesn't turn into a picture.

Placard next to the hook + cockpit placard (133.49) · fly the lowest of hook, RLC manual and type-cert limits

In this book, the cargo hook is one page: exploded part by part, every piece labeled, the electric and the manual release drawn where they sit, and a box with the design factor: 2.5 × for cargo, 3.5 × for human external cargo.

The same goes for the four load classes, the long line, the sling angle factor, the pre-job briefing and HOGE: each one has its own page.

So you look at the hook, you know what every part does, and you explain it without going back to the manual.

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • Load classes explained only in words
  • You walk into the test still unsure
Under 14 CFR 1.1, rotorcraft-load combinations are classified by the nature of the external load. In a Class A combination, the load cannot move freely, cannot be jettisoned and does not extend below the landing gear. In Class B, the load is jettisonable and is lifted free of land or water during the operation. In Class C, the load is jettisonable and remains in contact with land or water. Class D means any combination other than A, B or C that has been specifically approved by the Administrator.

  • The key limits in a box
  • You see it and you get it

One Page, One Topic, All Clear

Think of it this way:

You're the designated pilot, the inspector is across the table, and he asks which class covers a load that stays in contact with the ground the whole time.

You've already opened the load classes page: A, B, C and D drawn side by side, the load fixed, lifted free, still touching the ground, and a box with the one detail that separates each class.

Weight per leg → angle factor → tension per leg: the same 3 steps on every page

Same with the cargo hook, the sling angle factor, the pre-job briefing, the hand signals and HOGE: each one on its own page.

Helicopter External Load Illustrated is 8 parts and 60 topics, all drawn, and at the end you get one-page reviews plus the pilot and ground crew checklists.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I already fly and just need to prepare for Part 133 work?

Yes. It doesn't teach you to fly a helicopter and it doesn't start from zero: it assumes you already fly or work the pad, and puts the external load work in order, from load classes to load math, hand signals and emergencies, one page each. It also works for ground crew.

Is it up to date with Part 133, or an old summary from the internet?

It's built from the current text of 14 CFR Part 133 and the 14 CFR 1.1 definitions, cross-checked with FAA AC 133-1B, the FAA Helicopter Flying Handbook and, for ground crew, OSHA 29 CFR 1926.551. It isn't a summary copied from the internet: every topic comes from those sources.

Is this official FAA material?

No. It's independent study material. It isn't published, endorsed or approved by the FAA or any operator, it doesn't give you a certificate and it doesn't count as approved training.

Does it replace my operator's training or my flight manual?

No. It doesn't replace the operator's approved training, the Rotorcraft-Load Combination Flight Manual, your aircraft's RFM or the inspector's instructions. It helps you study and review them.

Are the practice questions the ones on the test?

No. They were written for this book to help you check what you know. They aren't official questions from any FAA test.

When and how do I get it?

The book and the 2 bonus books come as PDFs by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I print it?

Yes. The PDF is made to print, so you can keep it in the hangar or the truck.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the regulation with nothing sticking.

The cargo hook and the four load classes: you see them drawn, and it clicks.

You walk into the test, or onto the pad, knowing where everything is.
