What is the EASA AMC for CS-23.2510 regarding equipment, systems, and installations?

AMC1 23.2510 Equipment, systems, and installations, as per ED Decision 2026/003/R, references ASTM standards including F44 F3264, F3233/F3233M-23b, F3309/F3309M-24a, F3408/F3408M-21, F3061/F3061M-24a, F3230-25, and F3227/F3227M-25, with specific remarks and variances.

Has EASA accepted Table 3 of F3230-25 for aircraft powered by electric motors?

No, EASA has not yet accepted Table 3 of F3230-25 for aircraft powered by electric motors, and its use should be discussed with EASA.

What is the EASA variance regarding Oxygen Fire Hazards Analysis in ASTM standards?

At variance with F3227-25, Oxygen Fire Hazards Analysis is not completely covered in current ASTM standards; additional means of compliance have been developed by EASA for the specific application.

Which ASTM standard is referenced for systems and equipment in small aircraft, and what is the variance?

F3061/F3061M-24a, Standard Specification for Systems and Equipment in Small Aircraft. The variance is that system level verification per paragraph 4.4.2 is usually not acceptable and should be discussed with EASA.

Which ASTM standard is referenced for environmental systems in aircraft, and what is the EASA variance?

F3227/F3227M-25, Standard Specification for Environmental Systems in Aircraft. The variance is that Oxygen Fire Hazards Analysis is not completely covered in current ASTM standards, and additional means of compliance have been developed by EASA.
