Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: AMEND TSO C13D TO ESTABLISH SPECIFIC DONNING TESTS PERFORMANCE REQUIREMENTS AND COMPLIANCE CRITERIA, BASED ON ACCEPTED STATISTICAL SAMPLING PRACTICES THAT, AT A MINIMUM, SET A LOWER LIMIT ON THE NUMBER OF PERSONS TO BE USED IN EACH GROUP TEST; UPPER AND LOWER LIMITS ON THE NUMBER OF GROUP TESTS THAT MAY BE PERFORMED; THE MINIMUM PERCENTAGE OF PERSONS IN EACH GROUP WHO MUST PASS THE TEST IN ORDER TO COUNT THE GROUP TEST A SUCCESS; THE MINIMUM NUMBER OF GROUP TESTS THAT MUST BE SUCCESSFUL; AND THE COMPOSITION OF EACH GROUP, INCLUDING A REQUIREMENT THAT ONLY NAIVE SUBJECTS BE USED. (Supersedes Safety Recommendations A-79-067 and A-84-020)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to amend TSO C13D to create specific donning test performance requirements and compliance criteria, based on accepted statistical sampling practices. These requirements must include a minimum number of test subjects per group, limits on the number of group tests, a minimum pass rate per group, a minimum number of successful group tests, and a requirement that only naive subjects be used. This recommendation supersedes earlier ones A-79-067 and A-84-020.
