Federal Aviation Administration, DOT.
Final rule; technical amendment.
The Federal Aviation Administration (FAA) is making minor technical changes to a final rule published in the Federal Register on July 18, 2003 (68 FR 42932). That final rule amended appendices in 14 CFR parts 121, 125, and 135. In that final rule the FAA inadvertently did not make conforming amendments to two parts of Appendix M of part 121.
Effective July 18, 2005.Start Further Info

The FAA published a final rule on July 18, 2003, that made changes to recording specifications for digital flight data recorders required in 14 CFR parts 121, 125, and 135. Since that rulemaking, two editions of the Code of Federal Regulations have been published (2004, 2005), and each new edition includes two small errors that we are correcting with this technical amendment. Both errors are found in Appendix M of part 121. This appendix lists airplane flight recorder specifications for all 88 parameters that are required for aircraft operating under the rules of part 121.
One error is found in parameter 12a, Pitch Control(s) (non fly-by-wire systems), and the other is found in parameter 19, Pitch trim surface position. These errors were brought to out attention in May 2005 and we are correcting them as quickly as possible. The first error lists a “%” sign under the “Accuracy (sensor input) for parameter 12a, but a “°” (for “degree”) sign should be listed. The second error is a spelling error in parameter 19. Parameter 19 currently reads, “Pitch trime,” when it should read “Pitch trim.”
Need for Correction
The two errors published in current versions of 14 CFR are very minor. It is possible that an operator subject to the requirements described in Appendix M, part 121, could be confused by what is published. It is unlikely that these errors will directly affect safety, but it is necessary for us to make sure that all information in the appendix is 100% accurate.
The technical amendment will correct parameters 12a and 19 in 14 CFR, part 121, Appendix M.Start List of Subjects
