At variance with the note under Table 1 of [F3309/F3309M-21](https://www.astm.org/catalogsearch/result/?q=F3309-21), that Table 1 provides the applicable criteria for classification of a failure condition based on the severity of the effects. At variance with [F3309/F3309M-21](https://www.astm.org/catalogsearch/result/?q=F3309-21), paragraph 3.2.4, the term ‘on the order of’ means that, for various reasons, the component failure rate data is not precise enough to allow accurate estimates of the probabilities of failure conditions. This inability to establish accurate estimates of the probabilities of failure conditions results in some degree of uncertainty and the expression ‘on the order of’ is included in the descriptions of the quantitative probability terms that are provided to reflect this uncertainty. When calculating the estimated probability of each failure condition, that uncertainty should be accounted for in a way that does not compromise safety. In this context, ‘on the order of’ does not mean that for instance, the quantitative assessment of a major failure condition can be exceeded by a certain percentage to be ‘on the order of’ 1E-5. It means that there is uncertainty when determining the component failure rate, and that uncertainty should be accounted for in a way that does not compromise safety. At variance with Example 2 in paragraph 4.5.3.3 of [F3309/F3309M-21](https://www.astm.org/catalogsearch/result/?q=F3309-21), the use of service history data is limited to the fleet of an aeroplane type/aeroplane types for which the applicant is the holder of the TC(s), the owner of the data, or, if accepted by EASA, has concluded with the owner of the data an agreement that permits its use by the applicant for that purpose. ##### AMC1 23.2510 Equipment, systems, and installations *ED Decision 2026/003/R* **ASTM F44 F3264 Standard Specification for Normal Category Aeroplanes Certification** *9.3* *Equipment, Systems, and Installation* [F3233/F3233M-23b](https://www.astm.org/Standards/F3233.htm) Standard Specification for Flight and Navigation Instrumentation in Aircraft [F3309/F3309M-24a](https://www.astm.org/Standards/F3309.htm) Standard Practice for Simplified Safety Assessment of Systems and Equipment in Small Aircraft [F3408/F3408M-21](https://www.astm.org/Standards/F3408.htm) Standard Specification for Aircraft Emergency Parachute Recovery Systems **Remarks** — [F3061/F3061M-24a](https://www.astm.org/Standards/F3061.htm) Standard Specification for Systems and Equipment in Small Aircraft At variance with F3061-24a, paragraph 4.4.2, use of system level verification is usually not acceptable, and it should be discussed with EASA. — [F3230-25](https://www.astm.org/Standards/F3230.htm) Standard Practice for Safety Assessment of Systems and Equipment in Small Aircraft For aircraft that are powered by electric motors, EASA has not yet accepted Table 3 of F3230-25, and its use should be discussed with EASA. — [F3227/F3227M-25](https://www.astm.org/Standards/F3227.htm) Standard Specification for Environmental Systems in Aircraft At variance with F3227-25, Oxygen Fire Hazards Analysis is not completely covered in current ASTM standards.
