Ask an owner what the engine is worth and the answer usually starts with a number: time since major overhaul. That figure, and every oil change, cylinder replacement, and inspection behind it, lives in the engine logbook. Without it, the engine in the cowling is a question mark.
Engines also get removed, overhauled, and sometimes installed in a different airframe. Keeping a separate engine log means the history travels with the engine rather than staying behind in the airframe records. FAA rules (14 CFR 91.417) require owners and operators to keep maintenance records, including the current status of time since last overhaul for items that have one.
ASA’s SE-2 is The Standard hardcover engine log book, with a red cover that makes it easy to tell apart from the airframe log on the hangar shelf.
Quick answer: The ASA-SE-2 is The Standard hardcover engine log book from Aviation Supplies & Academics, a red-cover book for keeping an aircraft engine’s maintenance history separate from the airframe records. It’s for owners, operators, and mechanics who want the engine’s record to stay with the engine, available on Skyfarer and at Skyfarer Shop.

What usually goes in an engine log
- Engine identity. Make, model, and serial number at the front, so the book is tied to one engine.
- Overhaul history. When the engine was overhauled and by whom, and time since that overhaul.
- Maintenance entries. Oil changes, inspections, repairs, and parts replaced, each written and signed by the mechanic who did or supervised the work.
- Airworthiness directives. Engine ADs and how and when each was complied with.
Pilot tip: If you have an engine overhauled, ask for the overhaul paperwork to be kept with the engine log rather than in a separate folder. A buyer’s mechanic will want to see both together.

Frequently asked questions
Why not just use the airframe logbook?
Engines can be removed, overhauled, or moved to another airframe. A separate engine log keeps that history with the engine.
Can an owner make entries?
Owners commonly record hours, but maintenance entries on a certificated aircraft are made and signed by the person who performed or supervised the work, normally an appropriately certificated mechanic.
What color is it?
Red hardcover.
