GM 21.A.35(b)(2) Objective and Content of Function and Reliability Testing

• ED Decision 2012/020/R found in: Initial Airworthiness and Environmental Protection (748/2012) Part-21 Part-21L (Jul 2024)

GM 21.A.35(b)(2) Objective and Content of Function and Reliability Testing ED Decision 2012/020/R 1.       OBJECTIVE The objective of this testing is to expose the aircraft to the variety of uses, including training, that are likely to occur when in routine service to provide an assurance that it performs its intended functions to the standard required for certification and should continue to do so in service. 2.       CONTENT OF FUNCTION AND RELIABILITY TESTING The testing should cover both routine operations and some simulation of abnormal conditions. The details of the programme should be agreed with the Agency prior to commencement of testing. It may be possible to combine this testing with any required to demonstrate compliance with the applicable CS. This will be agreed on a case-by-case basis with the Agency. Where possible, testing conditions should be defined with the co-operation of an operator. A substantial proportion of the flying should be on a single aircraft. The flying should be carried out to a continuous schedule on an aircraft that is very close to the final type design, operated as though it were in service and should include a range of representative ambient operating conditions and airfields. ##### GM 21.A.35(b)(2) Objective and Content of Function and Reliability Testing *ED Decision 2012/020/R* 1.
