Diamond DA42 Planes Face Door Safety Mandates
Published Date: 8/25/2025
Proposed Rule
Summary
If you own a Diamond DA 42 airplane, the FAA wants you to update your flight manual, fix some parts, and regularly check the passenger door to keep it safe. This is because some doors have come loose mid-flight, which is super dangerous. These changes will help pilots fly safer without breaking the bank or causing big delays.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 0 costs, 3 mixed.
Flight Manual Update Required
If you own or operate a Diamond DA 42, DA 42 NG, or DA 42 M-NG airplane, the FAA proposes that you must revise the airplane flight manual (AFM) to add new operating limits, emergency procedures, and normal operating procedures. This change tells flight crews how to operate and respond to passenger door problems.
Airplane Modification Requirement
If you own or operate a Diamond DA 42, DA 42 NG, or DA 42 M-NG airplane, the FAA proposes that you must modify the airplane as specified by the directive. The modification requirement is intended to prevent passenger doors from separating from the fuselage in flight.
Repetitive Door Latch Inspections
If you own or operate a Diamond DA 42, DA 42 NG, or DA 42 M-NG airplane, the FAA proposes that you must perform repeated inspections of the passenger door latching and safety hooks. Inspections must check correct engagement, foreign objects, damage (including corrosion and wear that exceeds specified limits), and proper function.
