Federal Aviation Administration, DOT.
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. This AD requires you to modify the cockpit voice recorder (CVR) system. This AD is the result of instances where the recording quality of the CVR in the affected airplanes was so poor that the information was practically unrecoverable. The actions specified by this AD are intended to correct substandard quality cockpit voice recordings caused by the configuration of the present CVR system, which could affect air safety if important information that the CVR provides is not available after an accident. This information helps determine the probable cause of an accident and aids in developing necessary corrective action or design changes to prevent future accidents.
This AD becomes effective on November 22, 2000.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation as of November 22, 2000.

What caused this AD? The FAA has received reports of six instances where the recording quality of the cockpit voice recorder (CVR) system in Raytheon Beech Models 1900, 1900C, and 1900D airplanes was so poor that the information was practically unrecoverable.
Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Raytheon Beech Models 1900, 1900C, and 1900D. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on June 14, 2000 (65 FR 37311). The NPRM proposed to require you to modify the cockpit voice recorder (CVR) system.
Accomplishment of the proposed action as specified in the NPRM would be required in accordance with Raytheon Recommended Service Bulletin SB 23-3094, Issued: November, 1999.
What is the potential impact if FAA took no action? This condition, if not corrected, could affect air safety if important information that the CVR provides is not available after an accident. This information helps determine the probable cause of an accident and aids in developing necessary corrective action or design changes to prevent future accidents.
Was the public invited to comment? The FAA encouraged interested persons to participate in the making of this amendment. The following presents the concerns received on the proposal and FAA's response to these concerns:
What is the commenter's concerns? The commenter requests that FAA:
- Clearly define in the AD that the CVR must be installed and not just the incorporation of a kit; and
- Identify all affected CVR's by manufacturer or model number.
The commenter operates several of the affected airplanes in a configuration of freight-only, single pilot. These airplanes incorporate supplemental type certificates that allow operation with nine or fewer passengers and freight conversions. Under section 135.151 of the Federal Aviation Regulations (14 CFR 135.151), this operator does not have to operate with a CVR. The commenter believes that FAA could eliminate confusion as to whether the AD applied if the Applicability of the AD was written to specify that the CVR must be installed. Then, if you installed the CVR in the future, you would have to comply with the AD.
The commenter believes that identifying the CVR by manufacturer or model number would also clarify the Applicability of the AD.
What is FAA's Response to the Concerns? We concur that specifying that the CVR must be installed would clarify the Applicability of the AD. We have changed the wording in the final rule accordingly.
We do not concur with including the manufacturer or model number of the CVR in the Applicability of the AD. The intent of the AD is to modify the configuration of the CVR system, which includes the wiring and audio amplifier. Start Printed Page 59706The AD applies regardless of the CVR unit make and model that is installed.
The FAA's Determination
What is FAA's final determination on this issue? We carefully reviewed all available information related to the subject presented above and determined that air safety and the public interest require the adoption of the rule as proposed except for the change discussed above and minor editorial changes. These changes provide the intent that was proposed in the NPRM for correcting the unsafe condition and do not impose any additional burden than what was intended in the NPRM.
Compliance Time of This AD
What is the compliance time of this AD? The compliance time of this AD is “within 12 months after the effective date of this AD.”
Why is the compliance in calendar time instead of hours time-in-service (TIS)? The unsafe condition defined in this document is not a result of the number of times the airplane is operated, rather is a result of the present configuration of the CVR system. The chance of this situation occurring is the same for an airplane with 100 hours time-in-service (TIS) as it is for an airplane with 1,000 hours TIS. For this reason, FAA has determined that a compliance based on calendar time should be utilized in this AD in order to assure that the unsafe condition is addressed on all airplanes in a reasonable time period.
What is the cost impact of this AD on owners/operators of the affected airplanes? The following chart provides estimates of the cost this AD would impose upon the public:
|Action||No. of airplanes affected||Labor costs||Parts cost||Cost impact|
|Replacement/Incorporation of Modification kit||119||8 workhours at $60 per hour=$480 per airplane||$1,728||$262,752, or $2,208 per airplane.|
|Audio Amplifier Modification and Electrical Wiring Changes||377||8 workhours at $60 per hour=$480 per airplane||679||$436,943, or $1,159 per airplane.|
Does this AD impact various entities? The regulations adopted herein will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.
Does this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this action: (1) Is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.Start List of Subjects
