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 3: 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.
