Revisions to Cockpit Voice Recorder and Digital Flight Data 
Recorder Regulations

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The Federal Aviation Administration (FAA) is amending a final 
rule published in the Federal Register on March 7, 2008. That final 
rule amended cockpit voice recorder and digital flight data recorder 
regulations affecting certain air carriers, operators, and aircraft. In 
that final rule, the FAA failed to include conforming amendments to 
certain operating rules to ensure that certain new requirements apply 
to only newly manufactured aircraft.

DATES: Effective Date: These amendments become effective July 9, 2009.

SUPPLEMENTARY INFORMATION: The Federal Aviation Administration (FAA) 
published a final rule entitled ``Revisions to Cockpit Voice Recorder 
and Digital Flight Data Recorder Regulations'' in the Federal Register 
on March 7, 2008 (73 FR 12542). That final rule amended cockpit voice 
recorder (CVR) and digital flight data recorder (DFDR) regulations 
affecting certain air carriers, operators, and aircraft manufacturers 
by:
     Increasing the duration of certain CVR recordings,
     Increasing the data recording rate for certain DFDR 
parameters,
     Requiring physical separation of the DFDR and CVR, 
improving the reliability of the power supplies to both the CVR and 
DFDR, and
     Requiring that certain datalink communications received on 
an aircraft be recorded if datalink communication equipment is 
installed.
    Following publication of the final rule, an individual contacted us 
noting that Sec. Sec.  91.609(e)(1) and 135.151(a)(1) require a CVR to 
be installed in accordance with Sec.  23.1457(d) or Sec.  25.1457(d). 
He noted that when we added new requirements to Sec. Sec.  23.1457(d) 
and 25.1457(d) in the final rule without changing Sec. Sec.  
91.609(e)(1) and 135.151(a)(1), we mandated an immediate retrofit of 
existing aircraft to comply with the new certification requirements. He 
stated that this result appeared to conflict with our stated intent in 
the preamble to the final rule indicating that these new provisions 
would apply only to newly manufactured aircraft.
    We agree that our failure to amend certain operating rules not 
otherwise addressed in the final rule had this unintended effect. We 
took the opportunity to review all of the operating rules in Title 14 
Code of Federal Regulations (14 CFR) to determine whether other 
sections were similarly affected. Our review found similar issues in 
Sec. Sec.  121.344, 121.344a, 121.359, 125.226 and 135.152.
    We received another comment suggesting that we forgot to include 
the recorder location and mounting requirement for CVRs in airplanes 
operated under part 125. This is a requirement for newly manufactured 
airplanes. We agree that this was an oversight, and are amending Sec.  
125.227(h)(1) to correct this error.
    This document makes the appropriate amendatory changes to clearly 
reflect the impact that the final rule's new requirements have on 
Sec. Sec.  91.609, 121.344, 121.344a, 121.359, 125.226, 125.227, 
135.151 and 135.152. This amendment will not impose any additional 
restrictions on operators affected by these regulations.
    This document also corrects the change made to Sec.  129.1(b), 
which included certain sections that had been redesignated.

Correcting Amendment

    This correcting amendment will clarify the references to Sec. Sec.  
23.1457, 23.1459, 25.1457, 25.1459, 27.1457, 27.1459, 29.1457 and 
29.1459 in Sec. Sec.  91.609, 121.344, 121.344a, 121.359, 125.226, 
129.1, 135.151 and 135.152.
    This amendment also modifies references to Sec. Sec.  23.1457, 
25.1457, 27.1457, and 29.1457, by separating the two requirements in 
paragraph (d)(1) of each section into two subparagraphs. The first 
requirement will be designated (d)(1)(i); the second will be designated 
(d)(1)(ii). The second requirement, which was added in the final rule, 
applies only to airplanes manufactured after April 7, 2010. References 
to these sections contained in the operating rules are also being 
amended to conform to this modification.
    Similarly, this amendment modifies references to Sec. Sec.  
23.1459, 25.1459, 27.1459, and 29.1459 by separating the two 
requirements in paragraph (a)(3) of these sections into two 
subparagraphs. The first requirement will be designated paragraph 
(a)(3)(i); the second will be designated (a)(3)(ii). The second 
requirement, which was added in the final rule, applies only to 
airplanes manufactured after April 7, 2010. References to these 
sections contained in the operating rules are also being amended to 
conform to this modification.
    This amendment will revise Sec.  125.227(h)(1) to reference Sec.  
25.1457(e).
    Finally, this amendment corrects the list of sections included in 
Sec.  129.1(b).
