Note 1: The recommendation submitted to the FAA is acceptable except for oxygen bottles, which must meet the Department of Transportation Standards, 49 CFR, subchapter C.
Note 2: If the related draft Advisory Circular (AC) material (part of the ARAC recommendation) is used as a method of compliance, the use of paragraph 8d of the draft AC would not be acceptable to the FAA.
Note 3a: The ARAC proposed rule does not require evaluation of flight control jams during the time immediately before landing. The FAA does not accept this exclusion. However, flight control jams do not need to be evaluated if they are shown to be extremely improbable.
Note 3b: If the related draft advisory circular material (part of the FCHWG § 25.671 ARAC report) is used as a method of compliance, the use of paragraph 9.e(1)(v) and paragraph 10.b(4) would not be acceptable to the FAA for showing compliance with § 25.671(c) with respect to pilot strength without further justification. This FAA position is based on a recent review of pilot strength data.
Note 4: The MSHWG recommendation for rulemaking includes an analysis method. The analysis is a prerequisite for issuance of an exemption to 25.841(a) at amdt. 25-87.
