FAR 91.1721 — MU-2B Checklist Incorporation
FAR 91.1721 incorporates by reference the Mitsubishi MU-2B cockpit checklists into Part 91, listing each approved model checklist and document number.
In Plain English
FAR 91.1721 is the rule that formally pulls the Mitsubishi Heavy Industries MU-2B Cockpit Checklists into Part 91 by incorporation by reference. That means the checklists themselves carry the force of regulation when you operate an MU-2B — they aren't just manufacturer suggestions.
Key points:
- The Director of the Federal Register approved the incorporation under 5 U.S.C. 552(a) and 1 CFR part 51.
- The approved materials are available for inspection at the DOT Docket Management Facility in Washington, DC, and at the National Archives.
- Mitsubishi Heavy Industries America, Inc. (Addison, TX) is the source for the documents.
- The rule lists the specific FSB-accepted Cockpit Checklists by model and MHI document number, covering MU-2B variants including the -60, -40, -36A, -36, -35, -30, -26A, -26, -25, -20, -15, -10, and the original MU-2B, under Type Certificates A10SW and A2PC.
Why it matters operationally: if you fly an MU-2B under the SFAR 108 / Subpart N training and operating rules, you must use the correct, FAA-accepted checklist for your specific model and type certificate. Using the wrong checklist — or an unofficial version — is a regulatory deviation, not just a procedural one.

Oral Exam Questions a DPE Might Ask
Q1What does FAR 91.1721 incorporate by reference, and why does that matter to an MU-2B pilot?

FAR 91.1721 lists each accepted checklist by MU-2B model (for example MU-2B-60, -40, -36A, -36, -35, -30, etc.) along with its Type Certificate (A10SW or A2PC) and MHI document number, so you match the checklist to your aircraft's model and type certificate.

FAR 91.1721 states the approved material is available for inspection at the U.S. DOT Docket Management Facility in Washington, DC, and at the National Archives and Records Administration.
