14 CFR Part 121
[Docket No. FAA-2003-15682]
RIN 2120-AH81
Digital Flight Data Recorder Requirements
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; technical amendment.
-----------------------------------------------------------------------
SUMMARY: 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.
DATES: Effective July 18, 2005.

SUPPLEMENTARY INFORMATION:
Background
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 ``[deg]'' (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.
Technical Amendment
The technical amendment will correct parameters 12a and 19 in 14
CFR, part 121, Appendix M.
List of Subjects in 14 CFR Part 121
